It may be easier to use one of the application repackaging tools which enable you to capture any number of MSI and make the necessary customisations, including any changes to the registry or file system. Here's the list of some of such tools on Microsoft website: <https://learn.microsoft.com/en-us/windows/uwp/porting/desktop-to-uwp-root>

It has a GUI that allows for advanced customization of the APPX packages, without requiring you to have knowledge about the internals package schemas.
If you have any questions about it, let me know, would love to help.

<issue_start>username_0: I inspected the output parquet file of a spark job that always beaks, because of `Out of Memory Errors`.
I use `Spark 1.6.0` on `Cloudera 5.13.1`
I noticed that the parquet row group size is uneven.
The first and the last row group are huge. The rest is really small...
Shortened output from parquet-tools `RC = row count`, `TS = total size`:
```

Is this a known bug? How can I set the parquet block size (row group size) in Spark?
**EDIT:**
What the Spark application does is: It reads a big AVRO file, then distributes the rows by two partition keys (using `distribute by` in the select) and then writes a parquet file for each partition using:
`DF.write.partitionBy().parquet()`<issue_comment>username_1: Your RDD could be unevenly partitioned. The number of rows in each block is related to the size of the different partition of your RDD.
When a RDD is created, each partition contains roughly the same amount of data (due to the [HashPartitioner](https://spark.apache.org/docs/1.6.3/api/java/org/apache/spark/HashPartitioner.html)). After the processing of the Spark job, one partition could contain more data than another , maybe a filter transformation removed more rows from one partition than from another. The partitions can be rebalanced calling [repartition](https://spark.apache.org/docs/1.6.3/api/java/org/apache/spark/rdd/RDD.html#repartition(int,%20scala.math.Ordering)) before writing the parquet file.
**EDIT:** if the problem is not related to the partitions, maybe reducing the size of the row groups could help:
```scala
sc.hadoopConfiguration.setInt( "parquet.block.size", blockSize )
```

<issue_start>username_0: **About**: there are two threads running - one check for timeout (inactivity for some time), another one is where user works with UI.
**Problem**: timeout event occured slightly before user action, even though at the same millisecond, based on logs I can see it
```
2018-03-15 16:58:54:921 INFO {Thread-58} [InputTimeoutThread] Input timeout occured.
2018-03-15 16:58:54:921 DEBUG {AWT-EventQueue-1} [INPUT\_EVENT] Input event : functionKeyID = 10056
2018-03-15 16:58:54:921 DEBUG {AWT-EventQueue-1} [FunctionManagerImpl] Calling function [ID (10056)]
```
**Result**: inconsistent results as because of timeout logout event was called, but at the same time user action was done.
If timeout had happened before the user action it would have blocked the user to do any action, but this did not happen here as you can see.
Can anyone please advise how to tackle this? So that it can be guaranteed: no actions possible after some event happaned (in different threads).<issue_comment>username_1: Your RDD could be unevenly partitioned.

<issue_start>username_0: I need help getting certain numbers with a regex.
As I dont know much about regex I have only managed to see if the first two characters match with 95 - 99. ^([0-9][5-9]{4})
I have the numbers 00000 through 99999.
I want to exclude all the numbers that start with 95 and up.
So 00000 - 94999 is ok, 95000 - 99999 is not ok.<issue_comment>username_1: A regex is for validating if a string matches the set pattern. It is not for comparing numbers to see if they are within range. Convert the text (if that is what you are starting from) to a number and then use comparison operators in an if statement.
Upvotes: 0 <issue_comment>username_2: Regex is not well suited to performing numeric comparisons, from both a readability and performance standpoint. It would be much more sensible to extract the number and perform a numeric compare afterwards.
You've not mentioned a language, so I'll demonstrate with Python3.
```py
# input data
lines = [
"my line #1 :94995: message #1",
"my line #2 :95005: message #2"
]
for i, line in enumerate(x):
# extract a 5-digit number wrapped in colons
match = re.search(':([0-9]{5}):', line)
if match is None:
continue
# convert to a number, and verify
num = int(match.group(1))
if num >= 95000:
continue
# print any lines that meet our criteria
print("line %d meets our criteria! (%d)" % ( i, num ))
```
Will output:
```none
line 0 meets our criteria! (94995)
```
Upvotes: 0 <issue_comment>username_3: You could match the range of numbers 00000 - 94999 including leading zeroes you might try it like this:
* `^` From the beginning of the string
* `(?=\d{5}$)` Start with a positive lookahead that makes sure that the number is not longer than 5 digits until the end of the string
* `0*` Preprend with zero or more zeroes
* `(?:9[0-4][0-9]{3}|[1-8][0-9]{4}|[1-9][0-9]{1,3}|[0-9])` Match the range of numbers
* `$` The end of the string
Your regex could look like:
[`^(?=\d{5}$)0*(?:9[0-4][0-9]{3}|[1-8][0-9]{4}|[1-9][0-9]{1,3}|[0-9])$`](https://regex101.com/r/700uRS/1)

<issue_start>username_0: I am supposed to make a program to add all the elements inside the 2D rectangular array but the answer for this is supposed to be 31, instead it prints 33.
What am I doing wrong?
Heres the code:
```
public static int sum(int[][] array) {
int[][] numArray = {
{3, -1, 4, 0},
{5, 9, -2, 6},
{5, 3, 7, -8}
};
int sumOfRow = 0;
for (int i = 0; i < numArray.length; i++) {
sumOfRow += numArray[0][i];
sumOfRow += numArray[1][i];
sumOfRow += numArray[2][i];
}
System.out.println(sumOfRow);
return sumOfRow;
}
```<issue_comment>username_1: `numArray.length` is the number of rows, and your code treats it as the number of columns, so you ignore the last column of each row. The number of columns in a given row is `numArray[i].length`.
You should use nested loops:
```
for (int i = 0; i < numArray.length; i++) {
for (int j = 0; j < numArray[i].length; j++) {
sumOfRow += numArray[i][j];
}
}
```
Upvotes: 3 [selected_answer]<issue_comment>username_2: `numArray.length` is the length of outer array, you should use `numArray[0].length` instead of `numArray.length` which should give you expected results.
If you are using java 8, here is the solution:
```
int sum = Arrays.stream(numArray)
.mapToInt(arr->IntStream.of(arr).sum()) // sum the inner array
.sum(); // sum the outer array
```
Upvotes: 2 <issue_comment>username_3: As mentioned by the others already, `numArray.length` refers to the number of rows (or in other words the number of other arrays referenced by the references in `numArray`), and your code treats it as the number of columns and because there are fewer rows than columns you're getting un-expected results.
Nevertheless, the first index for any two-dimensional array should be the row index and the second should indicate the column index. username_1's answer indicates how to solve your current issue.
However, I just wanted to provide another more ideal solution in Java-8+ to sum the elements of your two-dimensional array.
```
int sum = Arrays.stream(numArray)
.flatMapToInt(Arrays::stream)
.sum();
```
It's more ideal because the `flatMapToInt` is the perfect method for this type of job and simply calling the `sum` terminal operation should render the results you need.

<issue_start>username_0: Part of the deliverables for the client include the source code of the project we are working on. I'm using maven with `mvn generate-sources`. The problem is that it includes all the dependencies and aggregates the sources per dependency. I'm trying to generate a flat structure with the `.java` files filtered on `groupid`.
The documentation is very evasive about [maven-source-plugin](https://maven.apache.org/plugins/maven-source-plugin/usage.html). All the searches I do end-up pointing me toward filtering resources, which is not what I'am looking for.
The structure of my project is a parent pom with children and I'm trying to achieve something like this:
```
org.apache.maven.plugins
maven-source-plugin
3.0.1
attach-sources
jar
com.mygroupid.project
```
What I am expecting:
* A 'fat' structure (all project sources aggregated by package name in one dir)
* No duplicate sources
* No code outside of my source group id
**Edit:**
Assuming a structure like this:
```
- module-1 pom.xml // aggregate project
|- module-1-core (has dependency to module-2 and module-2)
|- module-1-war
- module-2 pom.xml // aggregate project
|- module-2-commons
- module-3 pom.xml // aggregate project
|- module-3-services
- // etc...
```
I would like the archive as follows:
```
- big-fat-code-sources.zip
|- module-1-core sources + test source
|- module-1-war sources + test source
|- module-2-commons sources + test source
|- module-3-services sources + test source
|- // etc...
```<issue_comment>username_1: Using `source:aggregate` goal should solve this task:
```
mvn clean source:aggregate

Supposing you have the following project structure

```
With just following configuration in root pom:
```
org.apache.maven.plugins
maven-source-plugin

and the above command executed, it will produce a `.jar` in `target` folder, which will contain the all the *sources* of `modules` mixed together.

5. Apply extra filtering when unpacking the transitive dependencies:
1. Include only mrkrabs projects (the `useTransitiveFiltering` should take care of this but does not)
2. Exclude certain files we do not wanna see in the archive (.sql, .zip, .class, .jar)

<issue_start>username_0: I am currently working on an assignment where I have to be able to read a certain predetermined amount of lines of input, each of which correlate to a certain line of output. Simply put, if I have 200 lines of input, I should also have 200 lines of output. I read the input through a scanner on the standard input, copy pasting it into the standard input, and every line, except the last line, is automatically outputted. For the last line to appear, I have to press enter. How do I make it so that this last line automatically appears and I don't have to press enter?
```
int numberOfPackets = Integer.parseInt(in.nextLine());
for (int i = 0; i < numberOfPackets; i++){
String nextLine = in.nextLine();
if (nextLine.charAt(0) == 'D'){ //Check to see if the packet is a data packet or a router packet
out.print("\n" + dataParser(nextLine));
} else if (nextLine.charAt(0) == 'R'){
out.print("\n" + routeParser(nextLine));
}
}
```
This is the code that reads each line into input, is there something I'm missing?

<issue_start>username_0: I'm working with Bootstrap 4 dropdown and there are about 18 dropdown items.
Because the height is too much, popper.js automatically moves the dropdown away from its original position to the top of the screen. How do I prevent this?
I always want the dropdown to appear right below the button that toggles it.
Thanks
Posting code as requested - ( I'm using C# but the code should convey the point I'm hoping)

There is a new "display" option that disables popper.js dropdown positioning. Use `data-display="static"` to [prevent popper.js from dynamically changing the dropdown position](https://getbootstrap.com/docs/4.1/components/dropdowns/#options)...
**Bootstrap 4.0**
There are some issues with `popper.js` and positioning.
I've found the solution is to `position-relative` the `.dropdown`, and set it as the `data-boundary=""` option in the dropdown toggle:

Upvotes: 5 [selected_answer]<issue_comment>username_2: ZimSystems got it almost right in Bootstrap 4.1. To disable the dropdown changing direction while open, aka. it's x-placement="bottom-end", you should use the "flip" option, instead of the "display" option.
Display static disables the positioning entirely, while flip only disables the LIVE checks, that flip the dropdown upside down, when you scroll towards the top of the screen.
Upvotes: 2 <issue_comment>username_3: I achieved this in Bootstrap 4.3.1 by adding `data-flip="false"` to the dropdown element.
ex:
`[dropdown](#)`
Upvotes: 3 <issue_comment>username_4: In options, you can try to change `dropupAuto : true` to `dropupAuto : false`.

<issue_start>username_0: I'm using `ngx-perfect-scrollbar` with my Angular 5 project. I want to scroll the `div` to top when the route changes.
**dashboard.html**

@ViewChild(PerfectScrollbarDirective) perfectscroll: PerfectScrollbarDirective;
you will have instance and then you can call functions like scrollToTop()

<issue_start>username_0: I have some HTML (which I have no control over) coming from a DB and it contains lots of text and images. I need to insert a particular element before or after the first tag that has an `![]()` tag inside it.
Here is an example of the HTML:

```
This is as far as I can get to moving the `div` before the `img` element but obviously it will never work because the img is wrapped in an anchor tag. So how would I get jQuery to insert the `div` before the first anchor element that has an image inside of it?
```
$(".movethisdiv").insertBefore( $("section.main").find("a > img").first());
```
The above will insert the `div` before the `img` tag only, but within the `a` element. I want it to insertBefore the `a` element.<issue_comment>username_1: use [`.first()`](https://api.jquery.com/first/) and [`.parent()`](https://api.jquery.com/parent/) method here is example
```js
$("a").find('img').first($(".movethisdiv").insertBefore($("section.main > a img:first").parent()));
```

```js
$('.movethisdiv').insertBefore(
$("section.main").find('a').filter(function() { // get all anchors in main
return $(this).children('img').length; // filter out anchors with an image
}).first()); // get the first one

Find all `img` that are inside an `a` , select first one, and select it's parent.
Then insert the div before that parent
```js
let firstAnchor = $("a img").first().parent()
$(".movethisdiv").insertBefore(firstAnchor)

.movethisdiv {

```<issue_comment>username_1: The answer in the similar issue mentioned by @SawThinkarNayHtoo will get you most of the way. Here's that link again: [Importing Vufoira Scene into native android app](https://stackoverflow.com/questions/49106942/importing-vufoira-scene-into-native-android-app/49125433#49125433)
The gist of it is you want to export your Unity project while targeting Android. There are great tutorials elsewhere about how to do this, but here's the link from the answer above:
[Export Unity Project to Android Studio](https://bettercallunity.blogspot.in/2017/09/unity3d-tutorial-export-project-unity.html)
After following the steps above, I needed one more step:
1. In Android Studio, open your exported project and go to Edit > Find > Find in Path...
2. Search for "buildToolsVersion" without the quotes.
3. Replace all instances of versions "buildToolsVersion '28" with "buildToolsVersion '27".
If necessary, you can also edit the files without exporting. Search your project directory in the file system for "buildToolsVersion". You should find build.gradle files. Edit those as above.
Upvotes: 2 <issue_comment>username_2: Solved it!
my main issue was here :
[](https://i.stack.imgur.com/r2hms.png)
see all these 28.0.0-alpha files, the problem start occurring because of these, i am 100% sure of it because when i rolled back (thankfully am using version control) one of the main differences was that these libraries weren't there, i deleted them, but they kept coming back due to the "Play Service Resolver", so i figured it has nothing to do with whatever version i have installed in my Android SDK and it was 100% related to one of the plugins.
I created a new project, imported GoogleAdsMediation for Unity (that's the most important plugin) and did the "Resolving" thing, and there was no "28" files at all, so it wasn't google plugin, i kept doing with this with all the plugins we have.
import -> delete all libraries -> force resolve.
Until i found the culpable one, it was OneSignal, their dependencies configuration (or something) forced the resolver to import these "28.0.0-alpha" libraries, i deleted that version of OneSignal, imported an older one (from an older version of our project) and Boom! problem solved :)
I hope this helps.
cheers!

I generated a mainTemplate.gradle file that unity creates when you turn on "use custom gradle file" in the player settings and changed the buildToolsVersion line.
Original line in Assets/Plugins/Android/mainTemplate.gradle:

New:

I have above 3 condition and have 3 different block of html, above code just work but I felt the `!loading` declaration is too repeatable, how to improve code above?
`!loading` is a must because I don't want to show anything before the API fetch is pending.<issue_comment>username_1: Consider splitting into it's own component/function and then do this:
```

Upvotes: 2 <issue_comment>username_3: I really like [`recompose`](https://github.com/acdlite/recompose) for that:
```
const BaseComponent = ()=>(
this is your most common case (blue sky scenario)
);
// add special cases as branches
const FinalComponent = compose(
branch(({loading}) => loading, renderNothing)),
branch(({ad}) => ad.paid, renderComponent(PaidContent))),
branch(({ad}) => !ad.active, renderComponent(InactiveContent))),
)(BaseComponent)
```
I might have mixed up which case is your normal case and which cases are the exceptions. But this gives you an idea of how it works.
In our project our Base components never include loading and edge cases. This makes the normal case code a lot easier to read.
Note: The order of the `branch` calls is important.

<issue_start>username_0: I'm revising for an operating systems exam and currently trying to understand this processes question:
```
int main()
{
int v=0;
if(fork())
{
v++;
if(!fork())
{
fork();
v--;
}
}
}
```
So the question asks to
>
> 1. Draw a tree reflecting the parent-child hierarchy of processes created when the program above is run.
> 2. How many separate copies of the integer variable v are created? Discuss what is the value of v at the end of the program for each of the processes in the tree.
>
>
>
The main thing I'm having an issue with is the
```
if(fork())
```
line in the code. From looking at other stack overflows I realised that
```
if(fork()) = if(fork() != 0)
```
but I'm still having difficulty understanding whether the first if statement creates a child process? Because thats the only way that the second if statement:
```
(!fork())
```
can be executed?
This is how far I've got with my current understanding of the question.
[screenshot of attempt](https://i.stack.imgur.com/1C6Gl.png)
[](https://i.stack.imgur.com/1C6Gl.png)
Hopefully the diagram is legible! I'd be really grateful for any hints or pointers with this.<issue_comment>username_1: Notice that `if (fork()) /*etc*/` is *exactly* the same as
```
pid_t newtmp = fork();
if (newtmp != 0) /*etc*/
```
where `newtmp` is a fresh (new) variable name not occurring in your program (you could use `x1`, `x2` etc.... provided it has no occurrence in your program), and `pid_t` is some integral type (probably `int`).
Once you rewrote your code with *explicit* and *unique* names given to result of `fork` you'll understand it better.
BTW, the code is poor taste. When you use `fork` you need to handle *three* cases:
* the `fork` failed (e.g. because your system has not enough memory, or because you exceeded some limits) and gives -1
* the `fork` succeeded in the child so gives 0
* the `fork` succeeded in the parent, so gives the pid of the child.
But when you code `if (fork())` you are forgetting -or handling incorrectly- the first case (failure). It can *rarely* happen.
Read *carefully* (and several times) the [fork(2)](http://man7.org/linux/man-pages/man2/fork.2.html) man page. Notice that [fork](https://en.wikipedia.org/wiki/Fork_(system_call)) is difficult to understand.
Regarding limits, be aware of [setrlimit(2)](http://man7.org/linux/man-pages/man2/setrlimit.2.html) (and the `ulimit` bash builtin).
Upvotes: 2 <issue_comment>username_2: The answer is
```
if (fork ())
```
may or may determine whether a child process was created.
Go to the man page:
<http://man7.org/linux/man-pages/man2/fork.2.html>
We find that fork () returns three types of values:
* -1 => fork() failed
* 0 => return value in the child process
* a positive value => success and the PID of the child process.
Thus the test
```
if (fork ())
```
which is the same as
if (fork () != 0)
may succeed whether or not a child process was created. A competently written question would have said
```
if (fork () > 0)
```
Assuming everything works correctly:
```
int main()
{
int v=0;
if(fork()) // Creates a child process that does nothing.
{
v++;
if(!fork()) // Creates a child process that creates a child process (that then does nothing but decrement v).
{
fork();
v--;
}
}
}
```

I have a dataset in which every variable name has the prefix "v23\_1\_". I want to remove this prefix from all variables, but there are hundreds of them, so I am looking for a way to do it without using the RENAME statement hundreds of times.
I used this code:
```
begin program.
vdict=spssaux.VariableDict()
mylist=vdict.range(start="v23_1_dg_mnpdocid", end="v23_1_phq9t0_asku3t0")
nvars = len(mylist)
for i in range(nvars):
myvar = mylist[i]
mynewvar = myvar.strip("v23_1_")
spss.Submit(r"""
rename variables ( %s = %s) .
""" %(myvar, mynewvar))
end program.
```
Here is a list of the first few variables:
```
v23_1_dg_mnppusid
v23_1_dg_sigstatus
v23_1_dg_mnpvsno
v23_1_dg_mnpvslbl
v23_1_dg_mnpcvpid
v23_1_dg_mnpvisid
v23_1_dg_mnpvisno
v23_1_dg_mnpvispdt
v23_1_dg_mnpvisfdt
v23_1_dg_mnpfs0
v23_1_dg_mnpfs1
v23_1_dg_mnpfs2
v23_1_dg_mnpfs3
v23_1_dg_mnpfcs0
v23_1_dg_mnpfcs1
v23_1_dg_mnpfcs2
```
It worked ok for the first variables but then stopped with the message "renaming has created two variables named dg\_mnpfs". But the next variable would after stripping has the name "dg\_mnpfs2". What has happened is that the 1 at the end in "v23\_1\_dg\_mnpfs1" gets deleted too. And then it propbably intends to also delete the 2 at the end in "v23\_1\_dg\_mnpfs2", which will then lead to the same variable. I don't understand why this is happening and how I can avoid it.
Thanks a lot for your support!

On one hand, this is in-efficient, as it takes longer to run than what I am suggesting below.
On the other (and more important) hand, doing it variable by variable, does not guard against duplicate variables. I am guessing that you already have in your datafile a variable named `dg_mnpfs`, and you are attempting to create a new one by renaming `v23_1_dg_mnpfs`. Just check your datafile, after your python code breaks.
A more efficient way of writing you code would be to create lists with the old names, and new names, and submit the syntax with only one command.
```
begin program.
import spss,spssaux
vdict=spssaux.VariableDict()
mylist=vdict.range(start="v23_1_dg_mnpdocid", end="v23_1_phq9t0_asku3t0")
nvars = len(mylist)
my_new_list=[]
for i in range(nvars):
myvar = mylist[i]
mynewvar = myvar.strip("v23_1_")
my_new_list.append(mynewvar)
my_syntax="ren var (" + " ".join(mylist) + "=" + " ".join(my_new_list) +")."
spss.Submit(my_syntax)
end program.
```
And one more thing: the `strip` function removes the text from both ends of the variables. If you only want to remove the prefix, consider using `lstrip`. Details can be found [here, in the official documentation.](https://docs.python.org/2/library/string.html#string.lstrip)

```
*this is just to create a sample data to play with.
data list list/v23_1_var1 to v23_1_var6.
begin data
end data.
```
The following creates a list of the relevant variables:
```
SPSSINC SELECT VARIABLES MACRONAME="!list" /PROPERTIES PATTERN = "v23_1_*".
* the following macro creates one rename command for all the list.
define !doRename ()
rename variables (!eval(!list)=!do !i !in(!eval(!list)) !substr(!i, 7) !doend).
!enddefine.
!doRename .

<issue_start>username_0: I am currently having trouble with some styling and i'm looking for some help. Currently i have a couple of divs which are separated by a grey line, however the content of the div doesn't sit vertically in the middle (i have looked to implement other things online but still can't get it to work for some reason).
I also have an image that needs to be to the left of the title and text (and centred as above) but just can't get it to work!
I have attached my code and screenshots to make it a bit clearer :)
Any help would be appreciated - thanks!

//The image looks centred on this example but needs to be consistent rather than its side, as you can tell the spacing above the grey line is larger and needs to be the same across all divs (if that makes sense, let me know if it doesn't)

//Image needs to be to the left and content to the right at all times, at the minute it wraps incorrectly

Edit:
I'm not sure what you want with the images, but at least one of them should be static of size. See below for another possible implementation.

I don't know if you can change the image to a div and set it with `background-image` like I did though.
**Edit:** I guess not.

.search-result__image {
background-image: url('http://via.placeholder.com/240x180');

<issue_start>username_0: I am trying to obtain some effeciency improvements by changing this line in my fsharp syntax file (from [this](https://github.com/fsharp/vim-fsharp) plugin) from:
```
syn match fsharpModule "\%(\
```
to
```
syn match fsharpModule "\%(\
```
since the docs on the "\@<=" construct states that:
>
> For speed it's often much better to avoid this multi. Try using "\zs" instead |/\zs|.
>
>
>
However, this doesn't work and there is no highligting for
```
open SomeModule
```
How can this be? Doing a regular search in vim (with /) highligts the 'SomeModule' both when using the first and the second match pattern.<issue_comment>username_1: In the [Vim docs for the `\@<=` construct](http://vimdoc.sourceforge.net/htmldoc/pattern.html#/%5C@%3C=), the example of using `\zs` omits the parentheses that had been present in the equivalent pattern match using `\@<=`. I'm just guessing, but what happens if you try the following syntax match?
```
syn match fsharpModule "\
```
Upvotes: 2 <issue_comment>username_2: As described in `:help syn-mult-line`, `\zs` has a few restrictions in a syntax command:
>
> When using a start pattern with an offset, the start of the match is not allowed to start in a following line. The highlighting can start in a following line though. Using the "\zs" item also requires that the start of the match doesn't move to another line.
>
>
>
so very likely `@<=` is is the best possible solution.
Upvotes: 0 <issue_comment>username_3: This is caused by the syntax containment and because another syntax group exists for the `open` keyword that you're trying to assert.
Within syntax highlighting, `\zs` only affects the result (what Vim will highlight with the syntax group); the whole pattern (i.e. including the text before the `\zs`) is treated as the match when it comes to relationships with other syntax groups. (This implementation detail is not explicitly documented in the help.) The *positive lookbehind assertion* (`\%(...\)\@<=`), by contrast, is neither included in the result nor the actual match. That explains the difference in behavior that you see. (It has nothing to do with the optional grouping, as @username_1 suspected, nor with multiple lines as per @Sergio's answer, as `\s\+` will not allow a linebreak in between.)
I think ease of implementation is more important here, so it should be fine to use `\@<=`, even though the help recommends `\zs`. If you're willing to completely restructure the syntax script, this could be solved with something along these lines, assuming there's a `syntax keyword fsharpOpen open` somewhere:
```
syntax keyword fsharpOpen nextgroup=fsharpModule skipwhite open
syntax match fsharpModule "[a-zA-Z.]\+" contained
```

<issue_start>username_0: I am using <https://github.com/daneden/animate.css> this css class to animate the boxes in grid.If a user clicks on "Fahrenheit to Celsius conversion" then the box with fahtocel id moves.Same for second box , It works well what I have written but Itmakes no sense to write javascript function for each box, Is there a way to get id of clicked div and relate it with the box which has to move in one function.
```js
function bounce() {
$("#fahtocel").addClass("animated bounce");
setTimeout(function() {
$("#fahtocel").removeClass("animated");
$("#fahtocel").removeClass("bounce");
}, 1000);
setTimeout(genQuote(), 5000);
}
function bounce2() {
$("#box2").addClass("animated bounce");
setTimeout(function() {
$("#box2").removeClass("animated");
$("#box2").removeClass("bounce");
}, 1000);
setTimeout(genQuote(), 5000);
}
```
```html
* Fahrenheit to Celsius conversion
* Box 2
* Lorem 3
```<issue_comment>username_1: You can make this function, and call it twice when needed:
```
function bounceBox($box){
$box.addClass("animated bounce");
setTimeout(function(){
$box.removeClass("animated");
$box.removeClass("bounce");
}, 1000);
setTimeout(genQuote, 5000);
}
bounceBox($('#fahtocel'));
bounceBox($('#box2'));
```
There is probably more that can be done, but you didn't show the code for it.
Upvotes: 2 <issue_comment>username_2: You can pass the ID (as a string/text) for the DIVs you want to change as a parameter to the function.
HTML
`onclick="bounce('fahtocel')"`
JavaScript
`function bounce( elementID ){ ... }`
jQuery
`$('#' + elementID)`
As an aside, I also turned your first DIVs into buttons -- not something that you have to do, its just nice to use buttons for things that need to be clicked instead of shoe-horning that functionality into a DIV.
```js
function bounce( elementID ) {
var target = $('#' + elementID );
target.addClass("animated bounce");
setTimeout(function() {
target.removeClass("animated");
target.removeClass("bounce");
}, 1000);
setTimeout(function(){
genQuote( elementID );
}, 5000);
}
function genQuote( elementID ){
// you can pass the string for the ID to another
// function. it's just like a variable, but you
// need to make sure your function will send and
// receive them as nessecary.
$('#' + elementID ).html( new Date() );
// this is just randomly putting in the current date
// and time to show an update.
}
```

<issue_start>username_0: Comparing these statements
```
SELECT * FROM Table
WHERE
(field IS NULL OR field = 'empty_value')
```
vs.
```
SELECT * FROM Table
WHERE
COALESCE(field, 'empty_value') = 'empty_value'
```
in terms of performance, which one is better? Is there any difference?
I already know the first one requires a slightly more complex filter operation, while the second one needs +1 scalar computation prior the filter. The performance impacts of doing this in a single table are insignificant, but what may happen when the query is complex? And when there are multiple fields in this situation? Should I prefer one over the other?
PS: I am using `'empty_value'` as a generic way to describe a situation where the absence of a particular value (`=NULL`) and a particular value (`='empty_value'`) have the same meaning for the query. Changing anything in the table design or how it stores its values is not an option.
PS2: I am using SQL Server, but I would like to get a more generic answer about this issue. But, I would stick to SQL Server if the answer is implementation dependent.<issue_comment>username_1: The `COALESCE()` precludes the use of an index (i.e. it is not sargable). The `OR` offers the chance of using an index. However, this might get complicated if there are other conditions in the query.
Benchmarking the solution in one case will not give a definitive answer. If indexes are not an issue, I would not expect the performance to differ very much. However, the short-circuiting of the `OR` would give it an advantage even in that case.
Upvotes: 2 <issue_comment>username_2: Not an answer as such, but this is too much information for a comment and it is relevant to the question.
There is a third option which springs to mind in this instance:
```
SELECT *
FROM Table
WHERE field IS NULL
UNION ALL
SELECT *
FROM Table
WHERE field = 'empty_value'
```
This is sargable but splits the query into two parts, so it's up to you to test all the alternatives you have.

Code ts:
```
this.addsale = this.fb.group({
'invoice_number': new FormControl('', [Validators.required, Validators.nullValidator]),
'amount_paid': new FormControl('', Validators.required),
'notes': new FormControl('', Validators.required),
'Subtotal': new FormControl('', Validators.required),
'products': this.fb.array([]),
'total': new FormControl('', Validators.required),
'Unit_price': new FormControl('', Validators.required),
'Quantity': new FormControl('', Validators.required),
'Description': new FormControl('', Validators.required)
});
}
ngOnInit() {
this.products = this.ps.getProduct();
console.log(this.products)
this.pts.getAllProductType().subscribe(
producttype => {
this.producttype = producttype;
}
);
}
onaddsale() {
}
get total() {
let Total = 0;
for (let p of this.products) {
Total += p.Unit_price * p.Quantity;
}
return Total;
}
}
```
Can you suggest me how to implement update total when I change quantity or unie\_price?
Thank you<issue_comment>username_1: You can use ng-template for that. E.g.

And load components with their selectors directly in html.
```

Component 1 is going to be displayed when h.type is car and component 2 is going to be displayed when h.type is truck.

<issue_start>username_0: I'm new to this. I have created a navigation form with 3 tabs. when I click on one tab it opens a pop-up form where I chose a record from a drop-down. when I click on a command button to "open file" I want the form to open in the tabs 'sub-form window'. at the moment all it does is opens in a separate window.
how do I get the form to open in the navigation sub-form window where it is linked, with the correct information in the fields based on the combo box?

<issue_start>username_0: I want to make a switch statement for in my code whose cases go over a wide span of integers (1-15000) split into 3 sections: 1-5000,5001-10000,10001-15000.
I tried it once like this:
```
switch(number) {
case 1 ... 1000: (statement here);
```
This gave me a syntax error on the "..."- "expected a :".
Then I tried:
```
switch (number) {
case 1:
case 5000:
(statement);
break;
```
This method did compile but didn't work as intended, wrong answer for the cases which were not explicitly listed.
Couldn't find any other suggestions online.
Can anyone help?<issue_comment>username_1: This is not possible in standard C, although some compilers offer switching on a range as a compiler extension1.
The idiomatic way in your case is to write
```
if (number < 1){
// oops
} else if (number <= 5000){
// ToDo
} else if (number <= 10000){
// ToDo
} else if (number <= 15000){
// ToDo
} else {
// oops
}
```
Or a very crude way would be to write `switch((number - 1) / 5000)` which exploits integer division: mapping the cases you need to deal with to 0, 1, and 2.

```<issue_comment>username_1: It means the *run()* method inside your Spring boot application threw an exception.
My guess is that some spring bean failed to initialize due to differences in how your environments are set up.
There's no way tell though based on gradle stacktrace. Post the code/error from the actual springboot app.

Upvotes: 0 <issue_comment>username_3: It looks like that your application is exiting with 1 and the application is not logging the reason for some reason. (Probably the issue was happened before your logger was initialized.)
To find out the root cause of the error put your Spring Boot Application's main function's content in a try-catch and in the catch:
```
catch (Throwable t) {
System.out.println(t.getMessage());
t.printStackTrace();
}

<issue_start>username_0: I have a string as `key1(value1) key2(vallue2) key3(value3) key4(value4) key5(value5) k` and would like to extract them into a dictionary as below. I am able to extract values inside and outside of parentheses separately but not able to correlate and create the dictionary in python. Please assist.
```
result = {
"key1" : "value1",
"key2" : "value2",
"key3" : "value3",
"key4" : "value4",
"key5" : "value5",
}
```<issue_comment>username_1: 1. Your key-value pairs are apparently delimited with the sequence `') '` between them, so `re.split()` is a nice choice for the first step, with `'\)\s\+'` as a pattern. And remember to first trim the trailing ')', to not corrupt the last value.
2. When you split the string on that regular expression, well, simply iterate through the results list and push each key-value pair into the dictionary. String's `split()` method can be used to split a list item into a key-value pair with `'('` as separator (and maxsplit 1, for you don't expect any more opening parentheses in the item).
Upvotes: 0 <issue_comment>username_2: A solution using `regex`:
```
import re
s = "key1(value1) key2(value2) key3(value3) key4(value4) key5(value5)"
keys = re.findall(r"([A-Za-z0-9_]+)\(", s)
values = re.findall(r"\(([A-Za-z0-9_]+)\)", s)
result = {k: v for k, v in zip(keys, values)}
print(result)
# {'key1': 'value1',
# 'key2': 'value2',
# 'key3': 'value3',
# 'key4': 'value4',

<issue_start>username_0: I'm currently collecting timestamp's using an android application which for some users stored the timezone as for example "GMT+03:00" browsing online I found this is not a proper timezone and because of that when trying to build a datetime object in python using
```
from datetime import datetime
from dateutil import tz
import pandas as pd
filename="data.csv"
data=pd.read_csv(filename)
[ datetime.fromtimestamp(data['timestamp'].iloc[i],
tz=tz.gettz(data['timezone'].iloc[i]))
for i in range(data.shape[0]) ]
```
does not work well. For example using that datetime object as index to create a Pandas dataframe in order to use the rolling window feature does not work. Any idea how to transform the "GMT+03:00" into a proper timezone or some way to incorporate that information to build correctly a datetime object?
update:
Here is a sample of `data['timestamps']`:
```
[1520719558.0, 1520719558.0, 1520719558.0, 1520719558.0, 1520719561.0, 1520719561.0, 1520719561.0, 1520719561.0, 1520719562.0, 1520719562.0]
```
and a sample of `data['timezone']`:
```
['GMT+03:00', 'GMT+03:00', 'GMT+03:00', 'GMT+03:00', 'GMT+03:00', 'GMT+03:00', 'GMT+03:00', 'GMT+03:00', 'GMT+03:00', 'GMT+03:00']

```
import datetime, re
def get_tz(s):
'''Returns a datetime.timezone object.
Uses regular expression to extract the UTC offset from s.
Assumes s is in the form of "GMT+03:00" or "GMT-03:00".
Does NOT have exception handling.
'''
pattern = r'GMT([+-])(\d{1,2}):(\d{1,2})'
match = re.match(pattern, s)
sign, hh, mm = match.groups()
hh, mm = map(int, (hh, mm))
t_delta = datetime.timedelta(hours=hh, minutes=mm)
t_delta = t_delta * (1 if sign == '+' else -1)
return datetime.timezone(t_delta)
```
Usage:
```
>>> timestamp = 1520719558.0
>>> timezone = 'GMT+03:00'
>>> dt = datetime.datetime.fromtimestamp(timestamp, get_tz(timezone))
>>> dt.isoformat()
'2018-03-11T01:05:58+03:00'
>>> timezone = 'GMT-03:00'
>>> dt = datetime.datetime.fromtimestamp(timestamp, get_tz(timezone))
>>> dt.isoformat()
'2018-03-10T19:05:58-03:00'

<issue_start>username_0: There are some huge legacy systems whose dependencies on PHPs' `mcrypt` are extremely important and vital (including the data storage in database). I need to find a way to maintain this library while upgrading to PHP 7.2 (which already worked fine).
My local test environment is Windows. The live environment is run on CentOS.
Some of the answers I have seen is decrypting and change mcrypt to openssl (*I think that's not possible at the moment since there's a lot of data to decrypt*).
Another way lights to download a lower PHP version with `mcrypt`-support, copy the extension and add it to php.ini (I do not even know the folder).
Downgrading PHP to 5.6 it's not suitable due to security issues.
Any light in what could be done in this scenario?<issue_comment>username_1: Basically I think you have mentioned all possibilities and you do not have a choice. ***Do not downgrade to PHP 5.6 this approach has no future***.
MCrypt was removed from PHP for one of the main reasons why you want to upgrade PHP: Security. The MCrypt library is not maintained anymore. ***Therefore installing the MCrypt extension is also a bad idea***. But it can be a temporary solution (follow e.g. those instructions <https://serverpilot.io/community/articles/how-to-install-the-php-mcrypt-extension.html>).
The ***only good solution is migrating from mcrypt to something*** else. There are questions regarding this topic on Stackoverflow already (e.g. [Upgrading my encryption library from Mcrypt to OpenSSL](https://stackoverflow.com/questions/43329513/upgrading-my-encryption-library-from-mcrypt-to-openssl)). Alternativly you could use some encryption library. Migrating a large amount of code/data might be a pain but this is the most future-oriented approach in this case.
Upvotes: 4 [selected_answer]<issue_comment>username_2: Note that no code or information about the `mcrypt` options/code.
Probably the only problems non-standard null padding used by `mcrypt`. To decrypt with another implementation that does not support null padding (it is non-standard) just decrypt with no padding and then remove the null padding.
If you also must encrypt the same as `mcrypt` just add null padding and encrypt with no-padding.
Really consider migrating the current encryption or adding some flag that the encryption is (or not) `mcrypt` compatible.

1. Locate your PHP directory. Usually it is located on C:\Program
Files\PHP\v7.2
2. Then go to this url:
<http://pecl.php.net/package/mcrypt/1.0.3/windows>
3. Download the package that better meets your requirements. For example if
you are
using FastCGI and have a 64 bit Windows installation pick
*7.2 Non Thread Safe (NTS) x64*
4. Open the zip and copy php\_mcrypt.dll file to the C:\Program
Files\PHP\v7.2\ext directory.
5. Edit the php.ini file and add this to the Dynamic extensions
section:
*extension=php\_mcrypt.dll*
6. Save php.ini and restart your web server.
Hope it helps.

**< % int empid = (value of employeeid) % >**
Is there an easy way to do this?
Thanks for any help<issue_comment>username_1: EDIT: Only works in rails
```
def add_arrays(array_a, array_b)
results = []
array_b.in_groups_of(4).each do |group|
group.each_with_index do |record, j|
results << (record + array_a[j])
end
end
results
end
```
Not tested it but that should do the trick

b.zip(a * (b.size / a.size + 1)).map { |o| o.reduce(:+) }
#⇒ [69, 24, 62, 44, 86, 25, 72, 62, 68, 31]
```
Or, much better and more concise from @SimpleLime:
```
b.zip(a.cycle).map(&:sum)
```

```
b.map.with_index { |e, i| e + a[i % a.size] }
#=> [69, 24, 62, 44, 86, 25, 72, 62, 68, 31]

<issue_start>username_0: I have a Dictionary whose key values (string type) are as below:
* mark
* mark a
* mark b
* orange
* apple
* apple a
I also have a List(Of String) which contains:
* mark
* apple
I want to delete any entry in the Dictionary where any value in the List is a substring of the Dictionary item's key.
In the example above, the entries with the following keys will be removed from the Dictionary:
* mark
* mark a
* mark b
* apple
* apple a
How do I filter and delete those entries from the Dictionary without multiple loops?
Here is the sample code/pseudocode I have tried:
```
For Each whatKVP In whatDict
If IsSubstringFoundInAList(whatKVP.Key, listName) = True Then
listKeyDel.Add(whatKVP.Key)
End If
Next
For Each whatKey In listKeyDel
whatDict.Remove(whatKey)
Next
Private Function IsSubstringFoundInAList(ByVal strIp As String, ByVal listStr As List(Of String)) As Boolean
Dim whatStr As String
For Each whatStr In listStr
If strIp.Contains(whatStr) = True Then
Return True
End If
Next
Return False
End Function
```
In the code above, I need to use many (3) loops to complete the task. Is there any better way/neater code to complete it?<issue_comment>username_1: You can use List.Any() looks much cleaner in my opinion
```
Dim findString = "foo"
listOfString.Any(Function(stringInList)
Return stringInList.Equals(findString)
End Function)
```
if your looking for performance though, id suggest using [Linq](https://learn.microsoft.com/en-us/dotnet/visual-basic/programming-guide/language-features/linq/introduction-to-linq)
Upvotes: 1 <issue_comment>username_2: You can do this in a single statement. The following assumes that `whatDict` is your dictionary and `listName` is your list of key substrings.
```
whatDict = whatDict.Where(Function(kvp) Not listName.Any(Function(n) kvp.Key.Contains(n))) _
.ToDictionary(Function(kvp) kvp.Key, Function(kvp) kvp.Value)
```
This creates a new Dictionary containing only the KeyValuePairs from the existing Dictionary where the key does not contain any of the substrings in `listName`.
Upvotes: 2 [selected_answer]<issue_comment>username_3: This function should do the trick:
```
Public Function FilterDictionary(Of T, K)(Dictionary As IDictionary(Of T, K), FilterList As ICollection(Of T)) As IDictionary(Of T, k)
Return (From Item In Dictionary
Where Not FilterList.Any(Function(x) Item.Key.ToString.Contains(x.ToString))).
ToDictionary(Function(x) x.Key, Function(x) x.Value)
End Function
```
Usage:
```
Dim MyDictionary As New Dictionary(Of String, Integer)
Dim FilterList As New List(Of String)
'Fill Collections...
Dim FilteredDictionary = FilterDictionary(MyDictionary, FilterList)
```
Upvotes: 0 <issue_comment>username_4: You would need something like this. I used 'StartsWith' but you can change to 'Contains'
```
Dim outList As New List(Of String)
outList.Add("mark")
outList.Add("apple")
whatDict = whatDict.Where(Function(x) Not outList.Exists(Function(y) x.Key.StartsWith(y))).ToDictionary(Function(x) x.Key, Function(x) x.Value)
```

<issue_start>username_0: i am trying insert picture caption using Apache POI, but i dont have any ideas for it. I'm using
```
doc.createParagraph().createRun().addPicture(input,
Document.PICTURE_TYPE_PNG, "picture.png",
Units.pixelToEMU(603), Units.pixelToEMU(226));
```
to insert picture and now i would like to add caption for it to be able create Table of Figure.
I have tried use some styles
paragraph.setStyle("Legends");
but it changes only fonts i doesnt work like with "Header1" (I have template). I have looked into styles.xml (in my template where i inserted picture caption using word) and there is
```
-
```
so it looks like i just have to set paragraph w:name w:val as "caption". Am i right? How can i reach it?<issue_comment>username_1: What one should know about how the [inserting a table of figures](https://support.office.com/en-us/article/insert-a-table-of-figures-c5ea59c5-487c-4fb2-bd48-e34dd57f0ec1?ui=en-US&rs=en-US&ad=US) works in `Word`:
When we [add captions](https://support.office.com/en-us/article/add-format-or-delete-captions-in-word-82fa82a4-f0f3-438f-a422-34bb5cef9c81?ui=en-US&rs=en-US&ad=US), then each caption paragraph contains a sequence field `{SEQ figure \* ARABIC}`. The name "figure" is the name of the sequence field. Then, if a table of figures shall be created, `Word` collects all paragraphs which contains such a field to build the table of figures from those.
Until now (`apache poi` version 3.17) does not provide adding captions to figures nor inserting or creating a table of figures, at least as far as I know. So we must do it ourself using the low level [CTSimpleField](http://grepcode.com/file/repo1.maven.org/maven2/org.apache.poi/ooxml-schemas/1.1/org/openxmlformats/schemas/wordprocessingml/x2006/main/CTSimpleField.java).
Example:
```
import java.io.InputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;
import org.apache.poi.util.Units;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTSimpleField;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STOnOff;
public class CreateWordTableOfFigures {
public static void main(String[] args) throws Exception {
XWPFDocument document = new XWPFDocument();
XWPFParagraph paragraph;
XWPFRun run;
InputStream in;
CTSimpleField seq;
paragraph = document.createParagraph();
run = paragraph.createRun();
run.setText("Document containing figures");
paragraph = document.createParagraph();
run = paragraph.createRun();
run.setText("Lorem ipsum...");
//create paragraph containing figure
paragraph = document.createParagraph();
paragraph.setSpacingAfter(0); //Set spacing after to 0. So caption will follow immediately under the figure.
run = paragraph.createRun();
in = new FileInputStream("samplePict1.png");
run.addPicture(in, Document.PICTURE_TYPE_PNG, "samplePict1.png", Units.toEMU(150), Units.toEMU(100));
in.close();
paragraph = document.createParagraph(); //caption for figure
run = paragraph.createRun();
run.setText("Picture ");
seq = paragraph.getCTP().addNewFldSimple();
seq.setInstr("SEQ figure \\* ARABIC"); //This field is important for creating the table of figures then.
run = paragraph.createRun();
run.setText(": Description of sample picture 1");
paragraph = document.createParagraph();
run = paragraph.createRun();
run.setText("Lorem ipsum...");
paragraph = document.createParagraph();
paragraph.setSpacingAfter(0);
run = paragraph.createRun();
in = new FileInputStream("samplePict2.png");
run.addPicture(in, Document.PICTURE_TYPE_PNG, "samplePict1.png", Units.toEMU(150), Units.toEMU(100));
in.close();
paragraph = document.createParagraph();
run = paragraph.createRun();
run.setText("Picture ");
seq = paragraph.getCTP().addNewFldSimple();
seq.setInstr("SEQ figure \\* ARABIC");
run = paragraph.createRun();
run.setText(": Description of sample picture 2");
paragraph = document.createParagraph();
run = paragraph.createRun();
run.setText("Index of figures:");
//Create table of figures field. Word will updating that field while opening the file.
paragraph = document.createParagraph();
CTSimpleField toc = paragraph.getCTP().addNewFldSimple();
toc.setInstr("TOC \\c \"figure\" \\* MERGEFORMAT");
toc.setDirty(STOnOff.TRUE); //set dirty to forcing update
FileOutputStream out = new FileOutputStream("CreateWordTableOfFigures.docx");
document.write(out);
document.close();
}
}
```
Note, the inserted field `{TOC \c "figure" \* MERGEFORMAT}`, because it is set dirty, only forces updating that field while opening the file in `Word`. Creating the whole table of figures using `apache poi` without forcing `Word` doing that will be much more effort.

So for header1/header2 I neeed captions to be 1.1.1, 1.1.2, etc. Then adding another header2 they would restart at 1.2.1, 1.2.2. Here is the code for that. It also does not require you to create a table of contents as the answer from Richter (who I thank for pointing me in the right direction with this).
```
public void addCaption(String text) {
paragraph = doc.createParagraph();
paragraph.setStyle(STYLE_CAPTION);
paragraph.setSpacingAfter(0); // Set spacing after to 0. So caption will follow immediately under the figure.
run = paragraph.createRun();
run.setText("Figure ");
CTR ctr;
CTRPr ctrpr;
CTText ctText;
CTSimpleField seq = getParagraph().getCTP().addNewFldSimple();
String figureText1 = " STYLEREF 2 \\s ";
seq.setInstr(figureText1);
ctr = seq.addNewR();
ctrpr = ctr.addNewRPr();
ctrpr.addNewNoProof();
ctText = ctr.addNewT();
ctText.setStringValue("1");
ctr = paragraph.getCTP().addNewR();

axel's result:
```
Picture 2: Description of sample picture 2
PAGEREF \_Toc521591239 \h
1
```
manual insert result
```
Picture 2: Description
of sample picture 2
PAGEREF \_Toc521591266 \h
1
```
Having skimmed this thing, it seems that the run should be enveloped in a hyperlink object. ... and there are several subtle differences just to make things interesting.

<issue_start>username_0: I am a beginner in android studio. For weeks I have been stuck trying to read data from my database to my activity (Available Rides). Right now I am only transfering the data from one activiy to the other and puting it into text view.
In a previous activity I alreadt managed to save the data on the database.
Idealy I would like to have table view showing 3 columns. The first one beeing "Deprture" the next one "Arrival" and the third one "Time". Then in each line have each child.
I would be really thankful if anyone could help me!
Thank you in advance!
**Available Rides Activity:**
```
public class AvailableRides extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_available_rides);
// Get the Intent that started this activity
Intent intent = getIntent();
String messageTime = intent.getStringExtra(DisplayMessageActivity.EXTRA_MESSAGE);
String messageDep = intent.getStringExtra(DisplayMessageActivity.EXTRA_MESSAGE1);
String messageArr = intent.getStringExtra(DisplayMessageActivity.EXTRA_MESSAGE2);
// Capture the layout's TextView and set the string as its text
TextView textView1 = findViewById(R.id.textView26);
textView1.setText(messageTime);
TextView textView2 = findViewById(R.id.textView2);
textView2.setText(messageDep);
TextView textView3 = findViewById(R.id.textView4);

public static string/void sayGoodBye()
{
return "GoodBye";
}
}
static void Main(string[] args)
{
var gsgsg = PermenatEmployee.sayGoodBye;

```
Here I have choice of using `string` or `void` in the method.<issue_comment>username_1: I'm quite confused by the syntax here: `string/void`, if it's to indicate that it could be either, then to make a static function call you need to invoke the function with `()`, i.e.:
```
var gsgsg = PermenatEmployee.sayGoodBye()
```
That being said, you can't assign the return value of a `void` to a `var`.
You also can't have a method outside of class scope, so your example will fail to compile.

<issue_start>username_0: I am using the Native Geocoder in my Ionic app. Documented here
>
> [Ionic documentation](https://ionicframework.com/docs/native/native-geocoder/)
>
>
> [Github Repo](https://github.com/sebastianbaar/cordova-plugin-nativegeocoder)
>
>
>
This is the method in my provider -
```js
//This calls the Native geocoder and returns the geocoordinates.
getGeoCode(address: string): Promise {
console.log('The address key is - ' + address);
return new Promise((resolve, reject) => {
this.nativeGeocoder.forwardGeocode(address)
.then((nativegeocoordinates: NativeGeocoderForwardResult) => {
console.log('The coordinates are - ' + JSON.stringify(nativegeocoordinates));
let addressCoordinates: DeliveryAddressCoordinates = nativegeocoordinates;
resolve(addressCoordinates);
})
.catch((error: any) => {
console.log(JSON.stringify(error));
reject(error);
});
})
}
```
The method accepts an address string as input. So I get the address from google places API, and pass the description here.
Now, for certain addresses, it just doesn't seem to find the coordinates, and returns a "Cannot find a location" message. For e.g. *"Bhadra Brookefields Apartment B Block, Kundanahalli Lake Road, Kundalahalli, Brookefield, Bengaluru, Karnataka, India"* is a valid address and returns the coordinates, while *"Times Square 42 Street Station, New York, NY, USA"* does not find a match and returns a message saying - "Cannot find a location".
For more information the "Cannot find a location" seems to be originating from the [cordova plugin code here on line #182.](https://github.com/sebastianbaar/cordova-plugin-nativegeocoder/blob/master/src/android/NativeGeocoder.java), where it is referencing the Android class.
Is this a known issue? Or is there something that I am doing wrong?<issue_comment>username_1: At least one other person believes the plugin seems to be a bit of a hit/miss - a comment on this article below
[Ionic 2 – Geolocation and GeocodingIonic 2 – Geolocation and Geocoding](http://tphangout.com/ionic-2-geolocation-and-geocoding/)
The comment is from one Mr. Purple Edge, and I cannot link the comment itself because it is a disq, and not allowed by Stack.
So, I have resorted to what can be interpreted both as a solution or as a workaround. Instead of using the plugin, I am simply using the api, thus making a Http request to get the information.
Method to get the information (in a provider):
```js
getGeoCodefromGoogleAPI(address: string): Observable {
return this.\_http.get('https://maps.googleapis.com/maps/api/geocode/json?address=' + address)
.map(res => res.json());
}
```
Method call ->
```js
this._deliveryAddressService.getGeoCodefromGoogleAPI(event.description).subscribe(addressData => {
let latitude: string = addressData.results[0].geometry.location.lat;
let longitude: string = addressData.results[0].geometry.location.lng;
}
```
Of course, there needs to be the due process of registering for the key.

<issue_start>username_0: I am replacing standard input checkboxes with images and am running into two main issues with the code below:
1. No matter which image I click on (checkbox input), the value stays the same, instead of changing. (See the console for the printed value).
2. When an input is active, I am wanting to background color to change, but for some reason, on page load, all inputs have the red background color (there shouldn't be any background color). Then if I click on the input, nothing changes.
Does anyone see what I am doing wrong?
[Jsfiddle](https://jsfiddle.net/vdg6ka4d/1/)
```js
var interest = $('.interest');
interest.click(function() {
$('.interestCheck').prop('checked', true);
var check = $('.interestCheck').val();
console.log(check);
});
if ($('.interestCheck').prop('checked', true)) {
$('.interestBox').addClass('active');
}
```
```css
.interest {
width: 250px;
height: auto;
cursor: pointer;
}
.interestBox {
width: 100%;
border: 1px solid #CFCFCF;
border-radius: 2px;

.interestBox.active {

If you don't use `$(this)` inside your click function, then the code doesn't know what element you clicked, because `$('.interestCheck').val()` will return the first objects value.
You can also just `$('.interestCheck',this)`
```
var interest = $('.interest');
interest.click(function() {
$(this).find('.interestCheck').prop('checked', !$(this).find('.interestCheck').prop('checked'));
var check = $(this).find('.interestCheck').val();
$(this).find(".interestBox").toggleClass("active")
console.log(check);
});
```
**Demo**
```js
var interest = $('.interest');
interest.click(function() {
$(this).find('.interestCheck').prop('checked', !$(this).find('.interestCheck').prop('checked'));
var check = $(this).find('.interestCheck').val();
$(this).find(".interestBox").toggleClass("active")
console.log(check);
});
```
```css
.interest {
width: 250px;
height: auto;
cursor: pointer;
}
.interestBox {
width: 100%;
border: 1px solid #CFCFCF;
border-radius: 2px;
}
.interestBox.active {

You can do that by adding `this` as the second parameter of your jQuery selectors : `$('yourSelector',this)`.
* If you want to check/uncheck the checkboxes at every click, you need to replace
`$('.interestCheck', this).prop('checked',true)`
By
`$('.interestCheck', this).prop('checked', !$('.interestCheck', this).prop('checked'));`
* Plus, your last `if` can be replaced by a simple `.toggleClass` and needs to be inside your `click` handler.
```js
var interest = $('.interest');
interest.click(function() {
$('.interestCheck', this).prop('checked', !$('.interestCheck', this).prop('checked'));
var check = $('.interestCheck', this).val();
console.log(check);
$('.interestBox', this).toggleClass('active');
});

You need to make use of `this` keyword which means the element on which the event happens. You can then find the checkbox inside that element, change it's checked status and also find the `interestBox` you want to activate.
Also you find the other elements that may have been activated and deactivate them.
Your whole logic must be inside the click function. If you use the `if` outside the function, that condition will be executed on `window.load` or `dom.ready` etc, but it will executed BEFORE you click on the item. So the `if` is useless. It checks, sees that the checkbox is not checked and doesn't update and re-check the condition after the click event occurs.
```js
let interest = $('.interest');
interest.click(function() {
let targetCheck = $(this).find('.interestCheck'),
notCheck = $('.interestCheck').not(targetCheck)
notCheck.prop('checked', false);
notCheck.siblings(".interestBox").removeClass('active');
targetCheck.prop('checked', true);
targetCheck.siblings(".interestBox").addClass('active');
});
```
```css
.interest {
width: 250px;
height: auto;
cursor: pointer;
}
.interestBox {
width: 100%;
border: 1px solid #CFCFCF;
border-radius: 2px;
}
.interestBox.active {
background: red;
}
.interestBox img {
width: 100%;
}
.interestTitle {
font-size: 1.3rem;
text-align: center;
margin: 5px 0 0 0;

<issue_start>username_0: I have a matrix A and I want to find per column the last two non-NaN values.
For example, generate the following matrix:
```
A = [NaN, 3, NaN; 5 5 5; NaN 1 9; 4 1 4; NaN 6 NaN; 6 2 9]
```
I want to get the following result:
```
B =
4 6 4
6 2 9
```
**How can I do this in the most efficient way, without a for-loop?**
---
I tried the following: `[row,col,v] = find(A,3,'last')`, but this returns something that I do not understand:
```
row =
5
6
col =
3
3
v =
NaN
9
```<issue_comment>username_1: This is how:
```
A = [NaN, 3, NaN; 5 5 5; NaN 1 9; 4 1 4; NaN 6 NaN; 6 2 9]
N=2; %last 2
IsOK=~isnan(A);
[~,I]=sort(IsOK);
Iok=I(end-N+1:end,:); %get last N
LinearIndxs=sub2ind(size(A), Iok, repmat(1:size(A,2),N,1));
Result=A(LinearIndxs)
```

It searches on a column-wise basis and returns the row and column locations of the last three non-zero values and their actual values. `NaN` is technically non-zero, which is why it is returned to you.
First start off with finding all locations that are not `NaN` in your matrix with `find`:
```
[I,J] = find(~isnan(A));
```
This will now return row and column locations of the values that were not `NaN`. We now get:
```
>> [I,J]
ans =
2 1
4 1
6 1
1 2
2 2
3 2
4 2
5 2
6 2
2 3
3 3
4 3
6 3
```
We can see a nice pattern forming. The left column shows you all row locations that were not `NaN` and the right column tells you which column that was.
Next what we can do is for the second column, find the point where we transition from one column to another. That will give us the locations of last element that was not `NaN` for each column. We can then subtract these indices by 1 to give us the locations of the second last element that was not `NaN`. We can use the [`diff`](https://www.mathworks.com/help/matlab/ref/diff.html) function to help us do that and checking to see when the distance is non-zero. Note that this will decrease the size of the output by 1 because we're computing pairwise distances, but simply pad a 1 at the end because this signifies the end of the last column and this is where we want to find the last two elements of the column:
```
>> d = [diff(J) ~= 0; 1];
>> [J d]
ans =
1 0
1 0
1 1
2 0
2 0
2 0
2 0
2 0
2 1
3 0
3 0
3 0
3 1
```
Now let's take the output of `diff` and also shift everything up by 1:
```
d(1:end-1) = d(1:end-1) | d(2:end);
```
This will allow us to mark the second last element of each column to capture:
```
>> [I J d]
ans =
2 1 0
4 1 1
6 1 1
1 2 0
2 2 0
3 2 0
4 2 0
5 2 1
6 2 1
2 3 0
3 3 0
4 3 1
6 3 1
```
Last but not least, we now sample the first two columns of the above matrix where the third column is non-zero, convert these into linear indices and sample our matrix. We'll use a combination of [`reshape`](https://www.mathworks.com/help/matlab/ref/reshape.html) and [`sub2ind`](https://www.mathworks.com/help/matlab/ref/sub2ind.html) for that:
```
loc = d ~= 0;
out = reshape(A(sub2ind(size(A), I(loc), J(loc))), 2, size(A,2));
```
Thus:
```
>> out
out =
4 6 4
6 2 9
```
The final code is thus:
```
[I,J] = find(~isnan(A));
d = [diff(J) ~= 0; 1];
d(1:end-1) = d(1:end-1) | d(2:end);
loc = d ~= 0;
out = reshape(A(sub2ind(size(A), I(loc), J(loc))), 2, size(A,2));
```
Warning
=======
This assumes that you have at least two elements per column that are not `NaN`.

<issue_start>username_0: I have a webpage that has an animated flash gallery on its homepage.
By default, google chrome/firefox/safari ... does not let this page enable the flash plugin, so the gallery doesn't show.
Not only this happens, but also there is no prompt from the webpage requesting the user to enable flash, and the gallery completely disappear when flash is not enabled, so there's not even an error message saying that you need to enable flash to see the gallery.
What do I need to do on the page so that it requests the user to enable flash? Something like button to enable and then request permission from a browser.
Here is the sample which asks this permission in a browser.
<https://quickfire.gcontent.eu/aurora/default.aspx>
Cheers!<issue_comment>username_1: you should take the hint...Flash is dead...not supported...on its last legs.. covert your gaming/gambling website to html5>Canvas>SVG>scripting.
IE also has ActiveX filtering that blocks ActiveX controls from running on websites. see Tools ActiveX filtering.
The common design pattern for embedded plugins/ActiveX controls is to provide a fallback (link, image) nested INSIDE the parent object.
```
Opps.... your browser does not support flash, or it is disabled or it is blocked by ActiveX filtering.
```
For activeX filtering feature detection.. place a hidden div at the top of your document.... directly after the body.
eg.
```
ActiveX filtering for this site is turned on...
```
and at the bottom of the document (so it executes when the onload event fires) the following script block.
```
// Best Practice: First detect if ActiveX Filtering is enabled
if(document.documentMode&&document.documentMode>8){
if (typeof window.external.msActiveXFilteringEnabled == "unknown"
&& window.external.msActiveXFilteringEnabled() == true) {
document.getElementById('AXon').style.display = 'block';
//document.write("ActiveX Filtering has hidden this content.");
}
else {
// Either the browser isn’t IE, or ActiveX Filtering is not enabled in IE

<issue_start>username_0: I am using altbeacon: <https://altbeacon.github.io/android-beacon-library/>
I bind my beaconManager. and then I call this:
```
public void startListeningForBeacons(RangeNotifier rangeNotifier) {
try {
Region region = new Region("all-beacons-region", null, null, null);
// Tells the BeaconService to start looking for beacons that match the passed Region object
beaconManager.startRangingBeaconsInRegion(region);
} catch (RemoteException e) {
e.printStackTrace();
}
// Specifies a class that should be called each time the BeaconService gets ranging data, once per second by default
beaconManager.addRangeNotifier(rangeNotifier);
}
```
Which starts calling this function inside my application class:
```
@Override
public void didRangeBeaconsInRegion(final Collection beacons, Region region) {
if (beacons.size() > 0) {
Log.i("BluetoothService", "BluetoothService region The first beacon I see is about " + beacons.iterator().next().getDistance() + " meters away.");
if (didRangeBeaconsCallback != null)
didRangeBeaconsCallback.rangeCalled(beacons, region);
}else {
Log.i("BluetoothService", "BluetoothService region NO BEACONS: " + beacons.size());
if(PSBluetoothService.getInstance(PSApplicationClass.this).beaconUUID != null){
if (didRangeBeaconsCallback != null)
didRangeBeaconsCallback.rangeCalled(null, null);
}
}
}
```
But a lot of times, I get back o collection of size 0. Even thought I have 2 beacons in range.
I also tried with a LG Nexus 5 and a LeEco LePro2 and both return the correct list of beacons. What might go wrong when it comes to the Huawei?
If it helps, this is the list of beacon layouts I configure:
```
//sets the types of beacons that the library is searching for
public void setNeededTypesOfBeacons() {
beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout(BeaconParser.EDDYSTONE_UID_LAYOUT));
beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout(BeaconParser.EDDYSTONE_TLM_LAYOUT));
beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout(BeaconParser.EDDYSTONE_URL_LAYOUT));
beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout(BeaconParser.ALTBEACON_LAYOUT));
beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
beaconManager.getBeaconParsers().add(new BeaconParser()
.setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));
}
```
And I use this beacons: <https://nl.aliexpress.com/item/3-pcs-BLE-4-0-Base-Station-Ebeoo-iBeacon-USB/32752285433.html?spm=a2g0s.9042311.0.0.g1aZkv>

To transmit as a beacon, Android 5.0+ and firmware supporting Bluetooth Low Energy Peripheral Mode are required.

I cant test your code on Mate10 because I didn't have one now but I think your problem for about the android 8 read this link about the changes on android 8
<http://www.username_2tech.com/2017/08/07/beacon-detection-with-android-8>
Apps that use the library will need to upgrade to version 2.12+ in order to detect in the background on Android 8 devices. Version 2.13+ adds further enhancements for Android 8.1 restrictions of scanning with the screen off.
```
dependencies {
compile 'org.altbeacon:android-beacon-library:2+'
}

There are some bluetooth chips that are slow to detect the first beacon after starting scanning. This may be a hardware limitation that you must learn to live with.
I would suggest you rework the code to:
1. Look for beacons for much longer than 5 seconds and show results as soon as you find one. This way it will be fast on fast devices and slow on slow devices.
2. Don't unbind from the beacon manager until the app goes to the background. This way, it is already scanning in case you hit retry, and there won't be a delay in starting up scanning.
3. If you have control over the configuration of the hardware beacon, make sure it is transmitting at the highest rate possible. Some beacons are set to transmit only once every 1-5 seconds, which decreases the chance of detecting a packet within a short time interval. The more often you make the beacon transmit, the greater the odds of it getting detected within 5 seconds.

(for example the second `&ght` in text has an `href=` before it but the `href=` is not immediately before the previous Quotation mark and I dont want it to be matched) In my text, there is 3 `&ght` and I want first and 3rd one to be matched and the second one not matched based on ruled I described above.
I hope the question is explained enough! and I work on some offline text files and I can use notepad++, powershell or any other suitable engine.
Any help will be appreciated.<issue_comment>username_1: One way you could do it in PowerShell, if your inputs always have spaces between each item:
```
$a = '"href="dermatitis>" "blah blah blah >" href="lichen-planus>"'
$b = $a.Split(" ")
$c = $b | ? { $_ -match 'href="' }
Write-Output $c
```

```
# Set the regular expression
$regex = '(?<=href\=")(.*?)(?=")'
$sampleText = 'href="dermatitis>&ght" "blah blah blah >" href="lichen-planus>&ght"'
# Separate the single line string into 3 entities with " " as the delimiter
$sampleTextSplit = $sampleText.Split(" ")
$sampleMatches = $sampleTextSplit | Where-Object {$_ -match $regex} | Foreach-Object { $_.Replace(">","") }
# Show the results
$sampleMatches
```
This returns two objects:
```
href="dermatitis>"
href="lichen-planus>"
```

* `Ctrl`+`F`
* Find what: `href="[^"]*\K>(?=")`
* *check Wrap around*
* *check Regular expression*
* `Search in document`
**Explanation:**
```
href="[^"]* : search for href=" followed by 0 or more any charcater but "
\K : forget all we have seen until this position
> : literally >
(?=") : lookahead, make sure we have '"' after
```
Upvotes: 2 [selected_answer]<issue_comment>username_3: I know I'm 2 years late, but anyway :) Here's solution:
```
$string = 'href="dermatitis>" "blah blah blah >" href="lichen-planus>"'
$value = '>"'
$regex = 'href=".+?(' + $value + ')'
([regex]::matches($string,$regex).groups.value) | ? {$_ -eq $value}
```
Which will return 1st and 3rd values:
```
>"
>"
```

<issue_start>username_0: <https://finance.google.com/finance/converter> now redirects to <https://www.google.com/search>
Have they changed the url ?<issue_comment>username_1: I found a workaround this url is working: <https://finance.google.co.uk/bctzjpnsun/converter>
you can view old pages by inserting this 'bctzjpnsun' in the url. For instance portfolio view with issues in the layout:
<https://finance.google.co.uk/bctzjpnsun/portfolio?action=view&pid=1&pview=sview>
They are unfortunately in the process of removing it to push a new sleek layout www.google.com/finance without portfolio management features.
Obviously many are complaining but that did not help when they said the would terminate Google Reader loved by millions which means you should plan for an alternative.
EDIT: They should have communicated more on this. Most feature are easily replicable in google spreadsheets using `=GOOGLEFINANCE` function.

I guess you could use google search instead... just google something like "1 USD to ARS" (1 us dollar to argentine peso) and grab the result from there...
The search query would be something like <https://www.google.com.ar/search?q=1+usd+to+ars> and you would be grabbing the result from the corresponding DIV tag...
EDIT:
In this particular case, the source code shows
```html
1 U.S. dollar =20.2675314 Argentine pesos
```
so you would grab the div with the **vk\_ans** class.

Both API's offer free 1000 requests per month with 1 hour refresh. Payed plans offer more requests and more updates per hour. Open Exchange Rates also offers HTTPS requests with free plan.
Both API's responds in JSON format so it's very easy to parse the response data.
More info here:
---------------
**Open Exchange Rates**
<https://openexchangerates.org/>
**Fixer.io**
<https://fixer.io/>
How to convert currencies using free plan?
==========================================
In free plans, both API's give you access to currency rates list only. Can't use currency exchange endpoints, so to be able to convert currencies, you need to apply this formula, `toCurrency * (1 / fromCurrency)`
Using Open Exchange Rates and PHP:
----------------------------------
```
$url = 'https://openexchangerates.org/api/latest.json?app_id=YOUR_APP_ID';
$useragent = 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:37.0) Gecko/20100101 Firefox/37.0';
$rawdata = '';
if (function_exists('curl_exec')) {
$conn = curl_init($url);
curl_setopt($conn, CURLOPT_USERAGENT, $useragent);
curl_setopt($conn, CURLOPT_FRESH_CONNECT, true);
curl_setopt($conn, CURLOPT_RETURNTRANSFER, true);
$rawdata = curl_exec($conn);
curl_close($conn);
} else {
$options = array('http' => array('user_agent' => $useragent));
$context = stream_context_create($options);
if (function_exists('file_get_contents')) {
$rawdata = file_get_contents($url, false, $context);
} else if (function_exists('fopen') && function_exists('stream_get_contents')) {
$handle = fopen($url, "r", false, $context);
if ($handle) {
$rawdata = stream_get_contents($handle);
fclose($handle);
}
}
}
if ($rawdata) {
$rawdata = json_decode($rawdata);
$convertedCurrency = false;
$convertedCurrency = $rawdata->rates->$currB * (1 / $rawdata->rates->$currA);
}

<issue_start>username_0: I'm using Javascript to summarise data from a sharepoint list. I've got the query working and returning OK, and i can see from the console that it is returning everything I need, however I cannot work out how to parse it.
`jQuery.fromJSON` returns an error, as does the significant number of other things i've tried. Other than doing some regex or something i'm at a loss.
Can anyone suggest how this type of sharepoint response can be parsed so i can use the objects/data in each row.
Thanks

One way to do this coule be to write it out like:
```
covergroup alfa_cv @(posedge clk);
coverpoint alfa[0];
coverpoint alfa[1];
coverpoint alfa[2];
coverpoint alfa[3];
endgroup
alfa_cv alfa_covergroup = new;
```
But is there an easier way to make coverpoints to cover each of the bits in a bus?<issue_comment>username_1: Usually code coverage includes toggle coverage. You shouldn't have to create a covergroup for this. But you can create an array of covergroups
```
covergroup cg(input int index, ref bit [31:0] bus) @(posedge clk);
each_bit: coverpoint bus[index];
option.per_instance = 1;
endgroup
cg cgbits[32];
for (int index=0; index<$size(alfa);index++)
cgbits[index] = new(index,alfa);
```

However, if you want to write a covergroup then you can directly use `alfa` as coverpoint, as follow.

1 - create helper function `changeDatabases($database)`
2 - change you config database
```
if(database == 'baseDat1'){
config(['database.connections.mysql.host' => 'newHost']);
config(['database.connections.mysql.database' => 'newDatabase']);
config(['database.connections.mysql.username' => 'newUsername']);
config(['database.connections.mysql.password' => '<PASSWORD>']);
}
```
3 - you must create two different model if they are not equal
the change is good the duration of the session

<issue_start>username_0: I have an issue with posting data to Symfony to an endpoint that expects data formatted as a Symfony form.
The endpoint validates the posted data with a Symfony form. Normally, when I have a rendered form with twig. A relationship field will have a structure like this:
```
...
A product
Some other product
Product
Nice product
Stupid product
Interesting product
```
Now I don't have this, I just have an endpoint.
Whenever I want to post a record with say, "Nice product" I could just post a body containing form[product]=4 and the relationship is handled properly. But I only know I should post 4 because I check the rendered form.
The same goes when I need to update a record's relationship to product because I don't know what to send because the values are not related to anything, the option value is just an incremental value regardless of record id or anything.
How is this normally done? How could I manually create a post body containing the relationship of my choice?<issue_comment>username_1: If you have control over the Symfony form class, you can make the `value` attributes predictable with the [choices](https://symfony.com/doc/current/reference/forms/types/choice.html#example-usage) option:
```
$builder->add('product', ChoiceType::class, array(
'choices' => array(
'Nice product' => 'nice-product',
'NOT nice product' => 'not-nice-product'
),
));
```
Being aware of this mapping beforehand, you'd then submit a POST with `form[product]='nice-product'`.
Note: the `choices` option also works for the [EntityType form type](https://symfony.com/doc/current/reference/forms/types/entity.html#choices).
Upvotes: 2 [selected_answer]<issue_comment>username_2: If you are using a REST endpoint I assume that you are building a web app with JavaScript, a phone app or similar.
In this cases the normal procedure is that exists one endpoint to list this related entities and know it.
For example, in a javascript web app I render a form that have a select of this relationated entities, before show this field I call to an endpoint who return the ids and labels from this entities:
```
{
{“id”: 1, “label”: “value 1”},
{“id”: 2, “label”: “value 2”}
}
```
After that we render the field with this values and the user select one, and this is if is finally sent to your endpoint.
I hope this can help you

<issue_start>username_0: Can we update the UWP TextBlock's text from **AppService**?
Here I'm having the app service in different UWP Runtime Component project and that is added as reference to the UI project.
So I don't have direct connection with UI. But I need to update UI if the App is running as active.
**Note:** We may show the Toast and Live Tile instead. But want to know the possibility to directly update the UI.
**Edited: [18/3/18]**
I'm trying to merge existing WPF app within UWP using **DesktopBridge**. Here I need to have two way communication between both apps.
So created two AppServices separately in WPF and UWP to send and receive data in form of ValueSet and based on the requested data need to update the UI.
For WPF App having the UI and AppService in same project. For UWP App separated the AppServices as Runtime Component project (Out-Of-Proc). In this case both AppServices are working fine at runtime but cannot update the UWP UI (But able to update the WPF UI).
Also I tried to have in-proc services, in this case both AppServices are working fine but I cannot establish a connection from UWP to WPF. So I cannot send request from UWP (WPF to UWP is working).
So this is my actual problem. Want to know am I doing right? And is there any way to fix or any other better way to do it.
Followings are the **.appmanifest** code.
**As In-Proc service**
```
```
**As Out-Of-Proc service**
```
```<issue_comment>username_1: You could use an **In-process App Service** as described in the [documentation](https://learn.microsoft.com/en-us/windows/uwp/launch-resume/convert-app-service-in-process).
>
> App Services can now run in the same process as the foreground

This means you don't even have to move the code to a separate Windows Runtime Component and you may communicate with the UI in case it is active via `Window.Current`. However, you need to remember to make sure that your code manipulating the UI runs on the UI thread using `Dispatcher`.
Upvotes: 2 <issue_comment>username_2: If you have configured your AppService to run in-proc with the foreground app then you can update the UI directly. If the AppService is running out-of-proc, then you would need to send a request to the foreground app to update it's UI on your behalf, or go with toast/tile notifications.
Here is some info on how to make your AppService run in-proc with the application process:
<https://learn.microsoft.com/en-us/windows/uwp/launch-resume/convert-app-service-in-process>
Regarding the edited question, the typical pattern to use is this: When the WPF app launches, open the app service connection to the UWP. Now on both sides keep a reference to the respective instance of the AppServiceConnection object. This way you can do two-way communication and either side (UWP and WPF) can establish a request to the other side.

<issue_start>username_0: I have a content-type referring to an other content-type (a pair of articles), which refer to a content-type (an article).
I would like to redirect to the article url when the article block is clicked on my twig, so I came up with the code below
```
{% for i, value in node.field_articles_pairs %}
{% endfor %}
function onArticleClick(link) {
window.location.href = link;
}
```
Unfortunately, this is not working, I've got an error saying that the route does not exists.
How can I refer to my article url with that complex structure ?<issue_comment>username_1: There's two different approaches you can use to get the node/entity reference url for output:
* **Option 1:**
1. Create a separate display mode (maybe name it "teaser") under the Structure > Content Types > [Parent Content Type] settings.
2. Then create a node-type and display-mode-specific twig template (article--teaser.html.twig). In it, you can output the `related_article` div with click handler.
3. Then in your existing parent node-type twig template, you can simply output
`{{field_articles_pairs}}` as it will loop through and pull the custom twig template for each article entity referenced in the field.
* **Option 2:**
Add custom preprocess node functionality for the referencing/parent content type to include the urls with each field\_articles value.
Upvotes: 3 [selected_answer]<issue_comment>username_2: I believe this should be the syntax?
```
{% for article_pair in node.field_articles_pairs %}
{% for article in article_pair.entity.field_articles %}
{{ path('entity.node.canonical', {'node': article.entity.id}) }}
{% endfor %}
{% endfor %}
```
I think the first parameter in path is a string defining the type of path, not a value of the entity.

The problem is that when I run it I get this error:
**java.lang.IllegalStateException: Cipher not initialized for encryption/decryption**
Any idea what I'm doing wrong and how to fix it?<issue_comment>username_1: Reusing the same `Cipher` variable for different purposes is poor programming practice and confusing, and led you to these errors. You last left the `cipher` instance in `WRAP_MODE` prior to calling `doWrap()`. Then you supply the same instance to the `CipherOutputStream` constructors. Those require that the `cipher` object be in either `ENCRYPT_MODE` or `DECRYPT_MODE`.
Just call `Cipher.getInstance()` for every distinct use of a Cipher object. The overhead of that call will be insignificant in your program unless you're doing something very strange (and likely wrong) indeed.
Upvotes: 2 <issue_comment>username_2: You're using the `CipherOutputStream` values incorrectly. To be precise, the way your code is setup you don't need to use them *at all*. These output streams are used to *encrypt* and *decrypt* the data.
However, the data is already encrypted when calling `encWrappedData[0] = cipher.doFinal(dadesAEncriptarEnByte);` and `encWrappedData[1] = cipher.wrap(clauSecretaSimetrica);`.
So you can simply directly write the result of those calls to file by just using the `FileOutputStream`.
---
The RSA-wrapped AES key will always be limited in size, so it doesn't make sense to stream that information. If the message (`dades`) is large you may want to use streaming, and use the AES based cipher instance to perform the encryption, without putting all of the plaintext and ciphertext in a byte array in memory. In that case the `CipherOutputStream` could make sense.

<issue_start>username_0: I am having a react-redux action creation problem. My props are an empty object when I log props at the life cycle method componentDidMount()
```
import React, { Component } from 'react';
import { connect } from 'react-redux';
import { fetchSurveys } from '../../actions/index';
export class SurveyList extends Component {
componentDidMount() {
console.log(this.props);
this.props.fetchSurveys();
}
renderSurveys() {
return (
this.props.surveys.length &&
this.props.surveys.map(survey => {
return (
{survey.title}
{survey.body}
Sent On: {new Date(survey.dateSent).toLocaleDateString()}
Yes: {survey.yes}
No: {survey.no}
);
})
);
}
render() {
return {this.renderSurveys()};
}
}
function mapStateToProps({ surveys }) {
return { surveys };
}
export default connect(mapStateToProps, { fetchSurveys })(SurveyList);
```
Now according to the react-redux docs by default dispatch is included on the props so we do not need to explicitly call a mapDispatchToProps in the connect method in order to hit our action creators. fetchSurveys() is an action creator and I expect it to return a list of surveys which I then render.
However this.props = {}; so of course I cannot call .map on undefined at renderSurveys() as I do not get the surveys property on props either.
I am really troubled by why my props are empty. Can anybody shed some light onto this problem, I would be very grateful. I have tried using bindActionCreators and having my own mapDispatchToProps method, this doesn't work either.
Here are my actions.
```
import axios from 'axios';
import { FETCH_USER, FETCH_SURVEYS } from './types';
export const fetchUser = () => async dispatch => {
const res = await axios.get('/api/current_user');
dispatch({ type: FETCH_USER, payload: res.data });
};
export const handleToken = token => async dispatch => {
const res = await axios.post('/api/stripe', token);
dispatch({ type: FETCH_USER, payload: res.data });
};
export const submitSurvey = (values, history) => async dispatch => {
const res = await axios.post('/api/surveys', values);
history.push('/surveys');
dispatch({ type: FETCH_USER, payload: res.data });
};
export const fetchSurveys = () => async dispatch => {
console.log('called');
const res = await axios.get('/api/surveys');
dispatch({ type: FETCH_SURVEYS, payload: res.data });
};
```
My surveys reducer -
```
import { FETCH_SURVEYS } from '../actions/types';
export default function(state = [], action) {
switch (action.type) {
case FETCH_SURVEYS:
return action.payload;
default:
return state;
}
}
```

Combined reducer -

import { combineReducers } from 'redux';
import authReducer from './authReducer';
import { reducer as reduxForm } from 'redux-form';
import surveysReducer from './surveysReducer';
export default combineReducers({
auth: authReducer,
form: reduxForm,
surveys: surveysReducer
});
```<issue_comment>username_1: Have you used your reducer in combineReducers? you should have an index.js file in reducers folder (for example) which has something like this:
```
import {myreducer} from './myreducer';
const rootReducer = combineReducers(
{
myreducer: myreducer
}
);
export default rootReducer;
```
Do you have complete codebase somewhere? It looks like issue is not in provided code..
Upvotes: 0 <issue_comment>username_2: Seems that you forgot to add your reducer to main reducers file.
So, it depends on your code it should be:
```
// reducers/index.js
import { combineReducers } from 'redux';
import surveys from './surveysReducer';
const rootReducer = combineReducers({
surveys,
});
export default rootReducer;
```
Hope it will helps.

Shouldn't
```
import { SurveyList } from './surveys/SurveyList';
```
be
```
import SurveyList from './surveys/SurveyList';
```
Since the connected component is exported as default?

<issue_start>username_0: I want to check if an input string follows a pattern and if it does extract information from it.
My pattern is like this `Episode 000 (Season 00)`. The 00s are numbers that can range from 0-9. Now I want to check if this input `Episode 094 (Season 02)` matches this pattern and because it does it should then extract those two numbers, so I end up with two integer variables `94` & `2`:
```
string latestFile = "Episode 094 (Season 02)";
if (!Regex.IsMatch(latestFile, @"^(Episode)\s[0-9][0-9][0-9]\s\((Season)\s[0-9][0-9]\)$"))
return
int Episode = Int32.Parse(Regex.Match(latestFile, @"\d+").Value);
int Season = Int32.Parse(Regex.Match(latestFile, @"\d+").Value);
```
The first part where I check if the overall string matches the pattern works, but I think it can be improved. For the second part, where I actually extract the numbers I'm stuck and what I posted above obviously doesn't works, because it grabs all digits from the string. So if anyone of you could help me figure out how to only extract the three number characters after `Episode` and the two characters after `Season` that would be great.<issue_comment>username_1: In your regex `^(Episode)\s[0-9][0-9][0-9]\s\((Season)\s[0-9][0-9]\)$` you are capturing `Episode` and `Season` in a capturing group, but what you actually want to capture is the digits. You could switch your capturing groups like this:
[`^Episode\s([0-9][0-9][0-9])\s\(Season\s([0-9][0-9])\)$`](https://regex101.com/r/AotmAu/1)
Matching 3 digits in this way `[0-9][0-9][0-9]` can be written as `\d{3}` and `[0-9][0-9]` as `\d{2}`.
That would look like [`^Episode\s(\d{3})\s\(Season\s(\d{2})\)$`](https://regex101.com/r/AotmAu/2)
To match one or more digits you could use `\d+`.
The `\s` is a matches a [whitespace character](https://www.regular-expressions.info/shorthand.html). You could use `\s` or a whitespace.
Your regex could look like:
[`^Episode (\d{3}) \(Season (\d{2})\)$`](https://regex101.com/r/ICeS83/2)
```
string latestFile = "Episode 094 (Season 02)";
GroupCollection groups = Regex.Match(latestFile, @"^Episode (\d{3}) \(Season (\d{2})\)$").Groups;
int Episode = Int32.Parse(groups[1].Value);
int Season = Int32.Parse(groups[2].Value);
Console.WriteLine(Episode);
Console.WriteLine(Season);
```
That would result in:
```
94
2
```

^Episode (\d{1,3}) \(Season (\d{1,2})\)$
```
Captures the 2 numbers (even with length 1 to 3/2) and gives them back as a group.
You can go even further and name your groups:
```
^Episode (?\d{1,3}) \(Season (?\d{1,2})\)$
```
and then call them.
Example for using groups:
```
string pattern = @"abc(?\d{1,3})abc";
string input = "abc234abc";
Regex rgx = new Regex(pattern);
Match match = rgx.Match(input);
string result = match.Groups["firstGroup"].Value; //=> 234
```

<issue_start>username_0: My `Post` entity looks like this:
```
php
// ...
class Post
{
/**
* The ID generated manually.
*
* @ORM\Id
* @ORM\Column(type="integer", length=3)
*/
private $id;
//...
/**

* @ORM\OneToOne(targetEntity="DovStone\Bundle\BlogAdminBundle\Entity\Post", fetch="EAGER")
* @JoinColumn(name="parent_id", referencedColumnName="id")
*/
private $parent;
</code
```
One insertion works as expected and I can even get the parent `$post->getParent()` of a given post.
A problem occures when I try to make **another post insertion which has the same parent as the previous post inserted successfuly**.
I'll make this following example so you can get clearly what I mean:
Insertion #1:
**Id**: 613
**Parent**: NULL `//success`
Insertion #2:
**Id**: 156
**Parent**: 613 `//success`
Insertion #3:
**Id**: 156
**Parent: 613** `//fail`
Insertion #3 returns me `SQLSTATE[23000]: Integrity constraint violation: 19 UNIQUE constraint failed` because I think insertion #2 has already its parent it as **613**.
So what should I do to tell doctrine `parent_id` column must not be unique as `id` column.<issue_comment>username_1: If your $parent class could have more than one child, it should be usually mapped as ManyToOne relation
Upvotes: 1 <issue_comment>username_2: You need to change your relation from
```
@ORM\OneToOne
```
to

@ORM\ManyToOne

@ORM\JoinColumn(name="parent_id", referencedColumnName="id")

Any help or advice would be much-appreciated! I have already attempted pointing `reticulate` at different Conda environments and Python installations with no luck. Thanks!<issue_comment>username_1: I think I've figured this out. I misunderstood the reticulate documentation, taking it to mean I could share state between Python cells interactively in RStudio. After perusing the open issues on Github, it appears RStudio integration is still being worked on. When employing knitr directly to knit a document, I get the expected behavior with shared state between cells.
Upvotes: 3 <issue_comment>username_2: This is fixed in current RStudio e.g. `1.2.1114`. But if you are like me stuck with RStudio Server Pro 1.1.456 a workaround is to use `reticulate::repl_python()` to run python chunks by copy pasting them into a python console. You can close and open the console again if you need to run an R chunk in between - the state will be maintained. When you are done hacking around you can knit the whole file without problems.

<issue_start>username_0: Following the tutorial about Kafka Streams located at: <https://github.com/confluentinc/kafka-streams-examples/blob/4.0.0-post/src/main/java/io/confluent/examples/streams/WikipediaFeedAvroExample.java>
There is a line:
```
import io.confluent.examples.streams.avro.WikiFeed
```
As I suppose it relates to this file: <https://github.com/confluentinc/kafka-streams-examples/blob/4.0.0-post/src/main/resources/avro/io/confluent/examples/streams/wikifeed.avsc>
* How does Maven knows it is in `resource` not `java` folder?
* Why *io/confluent/examples/streams/**avro**/wikifeed.avsc* instead of ***avro***/io/confluent/examples/streams/wikifeed.avsc?
The other import is even more fantastic:
```
import io.confluent.kafka.serializers.AbstractKafkaAvroSerDeConfig;
```
* There is no `kafka` folder in the `java/io/confluent` folder.
<https://github.com/confluentinc/kafka-streams-examples/tree/4.0.0-post/src/main/resources/avro/io/confluent>.
How does all this magic suppose to work?<issue_comment>username_1: The `WikiFeed` class is created dynamically at build time using the `avro-maven-plugin` from the .avsc file you linked to. You can check how it's configured [in the section of pom.xml](https://github.com/confluentinc/kafka-streams-examples/blob/4.0.0-post/pom.xml#L346-L363).
The `AbstractKafkaAvroSerDeConfig` class comes from the `kafka-avro-serializer` dependency. Eclipse has a nice way of navigating from the individual class in the Editor view back to the Package Explorer which includes the Maven dependencies, like this:
[](https://i.stack.imgur.com/6UoTb.png)
Upvotes: 1 <issue_comment>username_2: The *magic* is made by [avro-maven-plugin](https://github.com/phunt/avro-maven-plugin) which you can find in the [pom.xml](https://github.com/confluentinc/kafka-streams-examples/blob/4.0.0-post/pom.xml):
```xml
org.apache.avro
avro-maven-plugin
${avro.version}
generate-sources
schema
src/main/resources/avro/io/confluent/examples/streams
${project.build.directory}/generated-sources
String
```
Quoting from the documentation of the plugin:
>
> Simple integration with dynamic languages. Code generation is not required to read or write data files nor to use or implement RPC protocols. Code generation as an optional optimization, only worth implementing for statically typed languages.
>
>
>
This is, at pre compile time, the plugin reads the content of *avsc* files and generate binary sources (for this case, Java classes) that then can be used in the code.
You can see the code generated by the plugin in `target/generated-sources`. There will be a folder structure and proper java (not class) files there.

<issue_start>username_0: I'm new to machine learning.
I've got a huge database of sensor data from weather stations. Those sensors can be broken or have odd values. Broken sensors influences the calculations that are being done with that data.
The goal is to use machine-learning to detect if new sensor values are odd and mark them as broken if so. As said, I'm new to ML. Can somebody push me in the right direction or give feedback to my approach.
The data has a datetime and a value. The sensor values are being pushed every hour.
I appreciate any kind of help!<issue_comment>username_1: Since the question is pretty general in nature, I will provide some basic thoughts. Maybe you are already slightly familiar with them.
1. Set up a dataset that contains both broken sensors, as well as good sensors. That is the dependent variable. With that set you also have some variables that might predict the Y variable. Let's call them X.
2. You train a model to learn te relationship between X and Y.
3. You predict, based on X values where you do not know the outcome, what Y will be.
Some useful insight on the basics, is here:

Twitter has developed a algorithm called ESD (Extreme Studentized Deviate) also useful.
<https://github.com/twitter/AnomalyDetection/>
However a good EDA (Exploratory data analysis) is needed to define the types of abnormality found in the readings due to faulty sensors.
1) Step kind of trend, where suddenly the value increases and remains increased or decreased as well
2) Gradual increase in the value compared to other sensors and suddenly very high increase
3) Intermittent spike in the data

And I added:
```
.BeerListItem-img {
height: auto;
max-height: 250px;
width: auto;
max-width: 250px;
}
```
And for card size I just added inside `BeerListItem` class to `Card` like so (`.BeerListItem-main-card`):
```
function BeerListItem(props) {
return (
{props.beer.name}
{props.beer.tagline}
);
}
```
And here is corresponding css to that component.
```
.BeerListItem-main-card {
width: 320px;
height: 415px;
}
.BeerListItem-img {
height: auto;
max-height: 250px;
width: auto;
max-width: 250px;
}
```
With that two changes, I've managed to achieve my goal.
Upvotes: 3 <issue_comment>username_3: by using display flex, my humble suggestion is adding "flex:1" to parent element of the card. This will allow your display to set the same size to each children and with that auto adjust each card to the same size, including the img.
I solved that, using that property.

<issue_start>username_0: Why does this happen?
In the following example, when i ISNULL to compare a blank int and a blank varchar they equal each other.
When the same logic is wrapped with a convert they do not equal each other.
```
DECLARE @myint int
DECLARE @mychar VARCHAR(200)
SET @myint = null
SET @mychar = NULL
SELECT CASE when CONVERT(VARCHAR(40),iSNULL(@myint,'')) = CONVERT(VARCHAR(40),ISNULL(@mychar,'')) THEN 1 ELSE 0 END AS 'poop'
SELECT CASE when iSNULL(@myint,'') =ISNULL(@mychar,'') THEN 1 ELSE 0 END AS 'poop'`
```
The reason this is an issue is because I am creating hashkeys with several appended fields. I recently changed the data type of one field from a varchar to an int (the field only ever stores an int) and now when that field is null the generated hashkey is different because the Convert function somehow sees the data as being different.<issue_comment>username_1: It's instructive if you also print out the results of the smaller expressions:
```
DECLARE @myint int
DECLARE @mychar VARCHAR(200)
SET @myint = null
SET @mychar = NULL
SELECT CASE when CONVERT(VARCHAR(40),iSNULL(@myint,'')) = CONVERT(VARCHAR(40),ISNULL(@mychar,'')) THEN 1 ELSE 0 END AS 'poop',
CONVERT(VARCHAR(40),iSNULL(@myint,'')),
CONVERT(VARCHAR(40),ISNULL(@mychar,''))
SELECT CASE when iSNULL(@myint,'') =ISNULL(@mychar,'') THEN 1 ELSE 0 END AS 'poop',
iSNULL(@myint,''),
ISNULL(@mychar,'')
```
You should be able to see that even after the `ISNULL` checks, you end up with `@myint` replaced by `0` and `@mychar` an empty string. Why? Because `ISNULL` will always returns data of the same type as its first argument, which for `@myInt` is an `int`. And an `int` cannot store an empty string. When an empty string is converted to an `int`, it's interpreted as `0`.
And that's also what's happening in your second comparison - we're comparing an `int` to a `varchar` and since `int` has higher precedence, that's the direction that the conversion happens in and so they compare equal.

Different functions handle data type precedence differently. So, for example `COALESCE` uses the highest data type precedence in used in the function.

<issue_start>username_0: I use stackoverflow on a regular basis to find answers to my problems, but I cannot seem to solve this one. So here is my first question:
I have a Google form that (amongst other things) asks for the duration of a job. I want the google spreadsheet to contain the form-answers, and add some columns. In this case, I want to add the cost of the job, using an hour rate of 126,-
But I keep running into problems in calculating with the duration: my script either tells me its a text (if I use getDisplayValue in retrieving the data), or it gives me a #NUM error in the spreadsheet itself.
Can anyone pinpoint me towards a solution how to retrieve the hours and the minutes from the form-field (time as duration), so I can do some basic math with it in the script?
I've setup a small form and connected spreadsheet showing my problems. The example form only asks for the duration, and places this in the spreadsheet in column 2. In the spreadsheet I've setup a script that runs on form submit an I try to explain all steps I do. The script should take the form input, convert it to hours (as a num-field) and multiply that with the PricePerHour. The result should be placed in column 3 on the same row of the form submit.
This is my script so far:
```
// CALCULATE COST OF JOB
function calculatePriceDuration(e) {
// get source data
var sourceSheet = SpreadsheetApp.getActiveSheet(); // connect to source sheet
var sourceRow = sourceSheet.getActiveRange().getRow(); // connect to event row (form submit)
// get destination data
var destinationSheet = sourceSheet; // connect to destination sheet
var destinationRow = sourceRow; // connect to destination row
var destinationColID = 3; // set column number of value to paste
// set variables
var colID_FormDuration = 2; // set column number where the form places the duration
var formDuration = sourceSheet.getRange(sourceRow, colID_FormDuration).getDisplayValue(); // get value for duration
// set price per hour
var PricePerHour = 126;
// calculate job price
var PriceForJob = formDuration * PricePerHour;
// set destination cell
destinationSheet.getRange(destinationRow,destinationColID).setValue(PriceForJob); // paste value in the 3rd column of the same row of form submit
}
```
the spreadsheet itself can be found [here](https://docs.google.com/spreadsheets/d/1jnLmIyjA15ll1bxEyQvJpMFVvC-qPpTR9202mJwyx1Y/edit#gid=480868069):
the form can be found [here](https://docs.google.com/forms/d/e/1FAIpQLSdniHbIK13G2YXY3TcCjxSqXZ5vxDZl6aEID7wEJqi9QrVajQ/viewform):
Any help is much appreciated!
Kind regards,

```
DECLARE @myint int
DECLARE @mychar VARCHAR(200)
SET @myint = null
SET @mychar = NULL
SELECT CASE when CONVERT(VARCHAR(40),iSNULL(@myint,'')) = CONVERT(VARCHAR(40),ISNULL(@mychar,'')) THEN 1 ELSE 0 END AS 'poop',
CONVERT(VARCHAR(40),iSNULL(@myint,'')),
CONVERT(VARCHAR(40),ISNULL(@mychar,''))
SELECT CASE when iSNULL(@myint,'') =ISNULL(@mychar,'') THEN 1 ELSE 0 END AS 'poop',
iSNULL(@myint,''),
ISNULL(@mychar,'')
```
You should be able to see that even after the `ISNULL` checks, you end up with `@myint` replaced by `0` and `@mychar` an empty string. Why? Because `ISNULL` will always returns data of the same type as its first argument, which for `@myInt` is an `int`. And an `int` cannot store an empty string. When an empty string is converted to an `int`, it's interpreted as `0`.
And that's also what's happening in your second comparison - we're comparing an `int` to a `varchar` and since `int` has higher precedence, that's the direction that the conversion happens in and so they compare equal.
But in the first case, you're effectively forcing the data conversion to happen in the other direction. And `0` converted to a `varchar` does not become an empty string.

<issue_start>username_0: This seems to be a duplicate question of an already asked one but not really. What I'm looking for is one or more regular expressions without the help of any programming language to change the following text `String.Concat( new string[] { "some", "random", "text", string1, string2, "end" })` into `"some" + "random" + "text" + string1 + string2 + "end"`.
I was thinking of using two regular expressions, replacing the commas with pluses, and then removing the `String.Concat( new string[] { ... })`. The second part is quite easy, but I am struggling with the first regular expression. I used a positive look-behind expression, but it matches only the first comma: `(?<=String\.Concat\(new string\[\] \{[^,}]*),`
I'm not an expert but I think that this is a limitation of the regular expression engine. Once the first comma is matched, the regular expression engine moves the starting matching index after the comma and it doesn't match anymore the look-behind group before it.

Is there a regular expression to make this substitution, pluses instead of commas, without the help on any programming language?<issue_comment>username_1: It's instructive if you also print out the results of the smaller expressions:

<issue_start>username_0: I created an arraylist with 4 items
```
val myList = arrayListOf("Item1", "Item2", "Item3", "Item4")
```
Then I printed a random item from myList
```
val randomNum = Random()
val randomItem = randomNum.nextInt(myList.count())
println(myList[randomItem])
```
Shouldn't this fail? Once randomItem is equal to 4? Ideally what I'm asking is that randomItem is returning an int from 0-4, correct? But the arraylist index is only 0-3. Should I do -1 to randomItem? I'm just confused because the program isn't throwing an error.<issue_comment>username_1: The [documentation](https://docs.oracle.com/javase/8/docs/api/java/util/Random.html#nextInt-int-) explains it pretty well:

<issue_start>username_0: I am doing some entity matching based on string edit distance and my results are a dictionary with keys (query string) and values [list of similar strings] based on some scoring criteria.
for example:
```
results = {
'ben' : ['benj', 'benjamin', 'benyamin'],
'benj': ['ben', 'beny', 'benjamin'],
'benjamin': ['benyamin'],
'benyamin': ['benjamin'],
'carl': ['karl'],
'karl': ['carl'],
}
```
Each value also has a corresponding dictionary item, for which it is the key (e.g. 'carl' and 'karl').
I need to combine the elements that have shared values. Choosing one value as the new key (lets say the longest string). In the above example I would hope to get:
```
results = {
'benjamin': ['ben', 'benj', 'benyamin', 'beny', 'benjamin', 'benyamin'],
'carl': ['carl','karl']
}
```
I have tried iterating through the dictionary using the keys, but I can't wrap my head around how to iterate and compare through each dictionary item and its list of values (or single value).<issue_comment>username_1: This is one solution using `collections.defaultdict` and sets.
The desired output is very similar to what you have, and can be easily manipulated to align.
```
from collections import defaultdict
results = {
'ben' : ['benj', 'benjamin', 'benyamin'],
'benj': ['ben', 'beny', 'benjamin'],
'benjamin': 'benyamin',
'benyamin': 'benjamin',
'carl': 'karl',
'karl': 'carl',
}
d = defaultdict(set)
for i, (k, v) in enumerate(results.items()):
w = {k} | (set(v) if isinstance(v, list) else {v})
for m, n in d.items():
if not n.isdisjoint(w):
d[m].update(w)
break
else:
d[i] = w
result = {max(v, key=len): v for k, v in d.items()}
# {'benjamin': {'ben', 'benj', 'benjamin', 'beny', 'benyamin'},
# 'carl': {'carl', 'karl'}}
```
Credit to @username_2 for the idea of manipulating `v` to `w` in second loop.
**Explanation**
There are 3 main steps:
1. Convert values into a consistent set format, including keys and values from original dictionary.
2. Cycle through this dictionary and add values to a new dictionary. If there is an intersection with some key [i.e. sets are not disjoint], then use that key. Otherwise, add to new key determined via enumeration.
3. Create result dictionary in a final transformation by mapping max length key to values.

<issue_start>username_0: ```
client_id visittype
1 Comprehensive Eval
1 Psychotherapy
1 Case Management
2 CM Eval
3 Comprehensive Eval
3 Case Management
3 Psychotherapy
4 Comprehensive Eval
5 Comprehensive Eval
5 Psychotherapy
```
I’m new to Python. I need to read a csv file with the two columns above. I need a count of each `client_id` that has at least one `visittype` entry other than an entry with ‘Eval’ in the name. Even if a `client_id` has more than one entry other than ‘%Eval%’, it should only be counted once. I’ll also need a count of the `client_ids` that do not have a `visittype` other than ‘%Eval%’. And, I need the averages for both.
In the above sample, `client_ids` 1, 3, and 5 will count as having the qualifying entry. 2 and 4 will not.
Total with: 3
Total without: 2
The logic will be something like:
```
For each client_id
If visittype NOT like '%Eval%'
with_count += 1
client_count +=1
else
without_count +=1
client_count +=1
endif
avg_with = with_count/client_count
avg_without = without_count/client_count
```
I realize that is not Python syntax.
I usually post code that I’ve tried when asking a question. I’m choosing not to do that this time since it turned into a mess.
Thanks in advance for any help. Feel free to post links to similar code that would help in learning Python.<issue_comment>username_1: A Python-Version of your Pseudo-Code would be like this:
```
for client in clients:
if not "Eval" in client:
with_count += 1
else:
without_count += 1
client_count += 1
avg_with = with_count / client_count
avg_witout = without_count / client_count
```
clients would be some kind of iterable from your csv and client would be from type string.
To address your only counted once problem, you could use an array and push the user\_id of counted entries into it.
```
counted = []
for i in range(clients):
if not "Eval" in clients[i].visittype and not clients[i].client_id in counted:
with_count += 1
counted.append(client.id)
else:
without_count += 1
client_count += 1
avg_with = with_count / client_count
avg_witout = without_count / client_count
```
Since we don't know how the structure of the data is you get from the csv, we cannot know how to implement it besides from theory.
Upvotes: 1 <issue_comment>username_2: Here's a solution by reading the data into a python dictionary, and then iterating over the keys (Patient ID).
```
import csv
with open("data.csv", "r") as f:
reader = csv.reader(f, delimiter=",")
patient_dict = {}
for line in reader:
key = line[0]
patient_id = line[1]
if key not in patient_dict:
patient_dict[key] = []
patient_dict[key].append(patient_id)
```
Here the output:
```
{'1': ['Comprehensive Eval', ' Psychotherapy', 'Case Management'],
'2': ['CM Eval'],
'3': ['Comprehensive Eval', 'Case Management', 'Psychotherapy'],
'4': ['Comprehensive Eval'],
'5': ['Comprehensive Eval', ' Psychotherapy']}
```
Here's the rest of it
```
with_counter = 0
without_counter = 0
for k, v in patient_dict.items():
for item in v:
if 'Eval' not in item:
with_counter = with_counter + 1
break
else:
without_counter = without_counter + 1
print('With = ' + str(with_counter))
print('Without = ' + str(without_counter))
#With = 3
#Without = 2

If I understand your issue, you can try this (no use of loops here)
```
#import the library & read your file
import pandas as pd
temp = pd.read_csv("path/to/your/file/your_file.csv")
# your condition is : "the type contains "Eval""
condition = temp["visittype"].str.contains("Eval")
with_count = temp.loc[~condition, "client_id"].unique()
# get the list of non "Eval" count
without_count = list(set(temp.loc[condition, "client_id"].unique()) - set(with_count))
client_count = len(temp.client_id.unique())
avg_with = len(with_count) / client_count
avg_witout = len(without_count) / client_count

a1 b1 d f d d na na na f
a1 b2 d d d f na f na na
a1 b3 d f d f na na d d
a2 c1 f f d na na d d f

Here we have V1-V10 columns. a1 and a2 are 2 distinct values in column V1,
b1-b3 in column V2 are distinct values related to a1 in V1 and c1-c3 related to a2.
column V3- V10 we have distinct values in each rows related to a1 and a2
Result i want is as below-
```
NewV1 max.occurrence(V3-V10)
a1 d
a2 f

to summarize i want to get the value with maximum occurrence(max.occurrence(V3-V10)) across column V3-V10 based on V1. NOTE= NA to be excluded.<issue_comment>username_1: Another possiblity using the `data.table`-package:

```
df %>%
gather("key", "value", V3:V10) %>%
group_by(V1) %>%
dplyr::summarise(max.occurence = names(which.max(table(value))))
```
This gives:
```
# A tibble: 2 x 2
V1 max.occurence
1 a1 d
2 a2 f
```

<issue_start>username_0: I use cx\_Oracle driver with SQLAlchemy to create engine.
Succesfully create enine like:
```
conn_string = 'oracle+cx_oracle://user:pass@host:1521/?service_name=some_service'
eng = create_engine(conn_string, encoding='utf8')
```
When I try to connect with:
```
eng.connect()
```
I catch the error:
```
DatabaseError: (cx_Oracle.DatabaseError) DPI-1004: unable to get error message
```
Using:
```
Python 3.5.2
cx-Oracle (6.2.1)
SQLAlchemy (1.1.15)
```
Does anybody know solution?<issue_comment>username_1: Run a script that looks like this in order to determine the source of the issue:
```
import cx_Oracle
try:
cx_Oracle.connect("user/pw@dsn")
except cx_Oracle.DatabaseError as e:
obj, = e.args
print("Context:", obj.context)
print("Message:", obj.message)
```

it needs to provide full TNS sting in create engine like:
```
eng = create_engine('oracle+cx_oracle://user:pass@full_TNS_string')

<issue_start>username_0: This worked at some point but I can't figure out what went wrong or how to correct course.
I'm getting the following on my index page:
NoMethodError in Admin::Locations#index undefined method `name' for nil:NilClass
It's coming from the following:
```
<% @locations.each do |location| %>
| <%= location.name %> | <%= location.state %> | <%= location.region.name %> |
<% end %>
```
Specifically the location.region.name. My locations controller looks like:
```
class Admin::LocationsController < Admin::ApplicationController
belongs_to_app :locations
add_breadcrumb 'Locations', :admin_locations_path
before_action :load_location, only: [:show, :edit, :update, :destroy]
def index
@locations = Location.ordered.paginate(page: params[:page])
@locations = @locations.search(params[:search]) if params[:search]
respond_with @locations
end
def show
respond_with @location
end
def new
@location = Location.new
respond_with @location
end
def create
@location = Location.new(location_params)
flash[:notice] = 'Location created successfully' if @location.save
respond_with @location, location: admin_locations_path
end
def edit
respond_with @location
end
def update
flash[:notice] = 'Location updated successfully' if @location.update_attributes(location_params)
respond_with @location, location: admin_locations_path
end
def destroy
flash[:notice] = 'Location deleted successfully' if @location.destroy
respond_with @location, location: admin_locations_path
end
private
def load_location
@location = Location.find_by!(id: params[:id])
end
def location_params
params.require(:location).permit(:name, :hours_operation, :abbreviation, :address_1, :address_2, :city, :state,
:postal_code, :phone, :fax, :region, :region_id)
end
end
```
Now if I change `location.region.name` to `location.region`, it will actually generate something like
```
#
```
Really there's only one region being applied so I'm at a loss.<issue_comment>username_1: You should replace it to:
```
location.region.try(:name)
```

Ah, but if you use simply use `location.region`, do you have that for all locations? I bet you $10 that there's at least one location without this. (meaning that this location's region is `nil`. Also meaning that it's a data problem and rolling code back likely wouldn't help)
A quick fix would be to do what @Kwstas suggests. Or this one (called "safe navigation operator" or "lonely operator"):
```
location.region&.name
```
But this is just a band-aid. If regions are mandatory for all locations, I'd look into ways of ensuring that. Maybe put some activerecord validations in place, or something.

<issue_start>username_0: I am using mongodb 3.6.3 on a centos 7 aws ec2 instance.
2 Questions (only one needs to be answered):
1. Why is the --logpath preventing the mongod command if done manually through the cli with `sudo mongod --storageEngine etc`
2. Why is `sudo service mongod status` showing the failure that it is?
When I run the below command, (since currently, `sudo service mongod start` isn't working but the below works) it fails when I specify the `--logpath` but will run without it. Unfortunately, when I run it without it, all of my logs end up in the `/` which is absolutely the wrong location.
`sudo mongod --storageEngine wiredTiger --dbpath /data --bind_ip 127.0.0.1,apiIP --logpath /var/log/mongodb/mongod.log --auth --fork`
Below is what happens when I try to run that above line as is.
`I CONTROL [main] log file "/var/log/mongodb/mongod.log" exists; moved to "/var/log/mongodb/mongod.log.2018-03-16T15-16-01".`
From what I can tell, it is conflicting with the currently existent
Just for reference, `sudo service mongod status` returns:
```

<issue_start>username_0: I'm trying to style points in a vector source in OpenLayers 4.
I've defined a style:
```
var pStyle = new ol.style.Style({
stroke: new ol.style.Stroke({
width: 6, color: [255, 0, 0, 1]
})
});
```
and added the style in the layer definition
```
var pLayer = new ol.layer.Vector({
source: new ol.source.Vector({
features: [p]
}),
style: pStyle
});
```
Commenting the style definition makes the point appear on the map so I'm assuming the rest of the code is fine. But I can't get my point to appear in red on the map.

Where am I going wrong?<issue_comment>username_1: You can use `ol.style.icon` for that.

<issue_start>username_0: I'm open to use a lib. I just want something simple to diff two collections on a different criteria than the normal equals function.
Right now I use something like :
```
collection1.stream()
.filter(element -> !collection2.stream()
.anyMatch(element2 -> element2.equalsWithoutSomeField(element)))
.collect(Collectors.toSet());
```
and I would like something like :
```
Collections.diff(collection1, collection2, Foo::equalsWithoutSomeField);
```
(edit) More context:
Should of mentioned that I'm looking for something that exists already and not to code it myself. I might code a small utils from your ideas if nothing exists.
Also, Real duplicates aren't possible in my case: the collections are Sets. However, duplicates according to the custom equals are possible and should not be removed by this operation. It seems to be a limitation in a lot of possible solutions.<issue_comment>username_1: **Comparing**
You can achieve this without the use of any library, just using java's [Comparator](https://docs.oracle.com/javase/8/docs/api/java/util/Comparator.html)
For instance, with the following object
```
public class A {
private String a;
private Double b;
private String c;
private int d;
// getters and setters
}
```
You can use a comparator like
```
Comparator comparator = Comparator.comparing(AA::getA)
.thenComparing(AA::getB)
.thenComparingInt(AA::getD);
```
This compares the fields `a`, `b` and the int `d`, skipping `c`.
The only problem here is that this won't work with null values.
---
**Comparing nulls**
One possible solution to do a fine grained configuration, that is allow to check for specific null fields is using a `Comparator` class similar to:
```
// Comparator for properties only, only writed to be used with Comparator#comparing
public final class PropertyNullComparator>
implements Comparator {
private PropertyNullComparator() { }
public static > PropertyNullComparator of() {
return new PropertyNullComparator<>();
}
@Override
public int compare(Object o1, Object o2) {
if (o1 != null && o2 != null) {
if (o1 instanceof Comparable) {
@SuppressWarnings({ "unchecked" })
Comparable comparable = (Comparable) o1;
return comparable.compareTo(o2);
} else {
// this will throw a ccn exception when object is not comparable
@SuppressWarnings({ "unchecked" })
Comparable comparable = (Comparable) o2;
return comparable.compareTo(o1) \* -1; // \* -1 to keep order
}
} else {
return o1 == o2 ? 0 : (o1 == null ? -1 : 1); // nulls first
}
}
}
```
This way you can use a comparator specifying the allowed null fields.
```
Comparator comparator = Comparator.comparing(AA::getA)
.thenComparing(AA::getB, PropertyNullComparator.of())
.thenComparingInt(AA::getD);
```
---
If you don't want to define a custom comparator you can use something like:
```
Comparator comparator = Comparator.comparing(AA::getA)
.thenComparing(AA::getB, Comparator.nullsFirst(Comparator.naturalOrder()))
.thenComparingInt(AA::getD);
```
---
**Difference method**
The difference (A - B) method could be implemented using two `TreeSets`.
```
static TreeSet difference(Collection c1,
Collection c2,
Comparator comparator) {
TreeSet treeSet1 = new TreeSet<>(comparator); treeSet1.addAll(c1);
if (treeSet1.size() > c2.size()) {
treeSet1.removeAll(c2);
} else {
TreeSet treeSet2 = new TreeSet<>(comparator); treeSet2.addAll(c2);
treeSet1.removeAll(treeSet2);
}
return treeSet1;
}
```
note: a `TreeSet` makes sense to be used since we are talking of uniqueness with a specific comparator. Also could perform better, the `contains` method of `TreeSet` is `O(log(n))`, compared to a common `ArrayList` that is `O(n)`.
Why only a `TreeSet` is used when `treeSet1.size() > c2.size()`, this is because when the condition is not met, the `TreeSet#removeAll`, uses the `contains` method of the second collection, this second collection could be any java collection and its `contains` method its not guaranteed to work exactly the same as the `contains` of the first `TreeSet` (with custom comparator).
---
**Edit (Given the more context of the question)**
Since collection1 is a set that could contains repeated elements acording to the custom `equals` (not the `equals` of the object) the solution already provided in the question could be used, since it does exactly that, without modifying any of the input collections and creating a new output set.
So you can create your own static function (because at least i am not aware of a library that provides a similar method), and use the `Comparator` or a `BiPredicate`.
```
static Set difference(Collection collection1,
Collection collection2,
Comparator comparator) {
collection1.stream()
.filter(element1 -> !collection2.stream()
.anyMatch(element2 -> comparator.compare(element1, element2) == 0))
.collect(Collectors.toSet());
}
```
**Edit (To Eugene)**
*"Why would you want to implement a null safe comparator yourself"*
At least to my knowledge there isn't a comparator to compare fields when this are a simple and common null, the closest that i know of is (to raplace my sugested `PropertyNullComparator.of()` [clearer/shorter/better name can be used]):
```
Comparator.nullsFirst(Comparator.naturalOrder())
```
So you would have to write that line for every field that you want to compare. Is this doable?, of course it is, is it practical?, i think not.
Easy solution, create a helper method.
```
static class ComparatorUtils {
public static > Comparator shnp() { // super short null comparator
return Comparator.nullsFirst(Comparator.naturalOrder());
}
}
```
Do this work?, yes this works, is it practical?, it looks like, is it a great solution? well that depends, many people consider the exaggerated (and/or unnecessary) use of helper methods as an anti-pattern, (a good old article by [<NAME>](https://blogs.msdn.microsoft.com/nickmalik/2005/09/06/are-helper-classes-evil/)). There are some reasons listed there, but to make things short, this is an OO language, so OO solutions are normally preferred to static helper methods.
---
*"As stated in the documentation : Note that the ordering maintained by a set (whether or not an explicit comparator is provided must be consistent with equals if it is to correctly implement the Set interface. Further, the same problem would arise in the other case, when size() > c.size() because ultimately this would still call equals in the remove method. So they both have to implement Comparator and equals consistently for this to work correctly"*
The javadoc says of [TreeSet](https://docs.oracle.com/cd/E17802_01/j2se/j2se/1.5.0/jcp/beta1/apidiffs/java/util/TreeSet.html) the following, but with a clear if:
>
> Note that the ordering maintained by a set (whether or not an explicit comparator is provided) must be consistent with equals **if it is to correctly implement the Set interface**
>
>
>
Then says this:
>
> See Comparable or Comparator for a precise definition of consistent with equals
>
>
>
If you go to the [Comparable](https://docs.oracle.com/javase/8/docs/api/java/lang/Comparable.html) javadoc says:
>
> It is strongly recommended (though not required) that natural orderings be consistent with equals
>
>
>
If we continue to read the javadoc again from Comparable (even in the same paragraph) says the following:
>
> This is so because the Set interface is defined in terms of the equals operation, but a TreeSet instance performs all key comparisons using its compareTo (or compare ) method, so two keys that are deemed equal by this method are, from the standpoint of the set, equal. The behavior of a set is well-defined even if its ordering is inconsistent with equals; it just fails to obey the general contract of the Set interface.
>
>
>
By this last quote and with a very simple code debug, or even a reading, you can see the use of an internal [TreeMap](https://docs.oracle.com/javase/8/docs/api/java/util/TreeMap.html), and that all its derivated methods are based on the `comparator`, not the `equals` method;
---
*"Why is this so implemented? because there is a difference when removing many elements from a little set and the other way around, as a matter of fact same stands for addAll"*
If you go to the definition of `removeAll` you can see that its implementation is in `AbstractSet`, it is not overrided. And this implementation uses a `contains` from the argument collection when this is larger, the beavior of this `contains` is uncertain, it isn't necessary (nor probable) that the received collection (e.g. list, queue, etc) has/can define the same comparator.
**Update 1:**
This jdk bug is being discussed (and considerated to be fixed) in here <https://bugs.openjdk.java.net/browse/JDK-6394757>
Upvotes: 0 <issue_comment>username_2: We use similar methods in our project to shorten repetitive collection filtering. We started with some basic building blocks:
```
static boolean anyMatch(Collection set, Predicate match) {
for (T object : set)
if (match.test(object))
return true;
return false;
}
```
Based on this, we can easily implement methods like `noneMatch` and more complicated ones like `isSubset` or your `diff`:
```
static Collection disjunctiveUnion(Collection c1, Collection c2, BiPredicate match)
{
ArrayList diff = new ArrayList<>();
diff.addAll(c1);
diff.addAll(c2);
diff.removeIf(e -> anyMatch(c1, e1 -> match.test(e, e1))
&& anyMatch(c2, e2 -> match.test(e, e2)));
return diff;
}
```
*Note that there are for sure some possibilities for perfomance tuning. But keeping it separated into small methods help understanding and using them with ease. Used in code they read quite nice.*
You would then use it as you already said:
```
CollectionUtils.disjunctiveUnion(collection1, collection2, Foo::equalsWithoutSomeField);
```
Taking <NAME>'s suggestion into account, you could even use `Comparator` to build your criteria on the fly:
```
Comparator special = Comparator.comparing(Foo::thisField)
.thenComparing(Foo::thatField);
BiPredicate specialMatch = (e1, e2) -> special.compare(e1, e2) == 0;
```

`HashingStrategy` allows the user to use a custom `hashCode()` and `equals()`. The Object's `hashCode()` and `equals()` is not used.
**Edit based on requirement from OP via comment**:
You can use `reject()` or `removeIf()` depending on your requirement.
**Code Example:**
```
// Common code
Person person1 = new Person("A", "A");
Person person2 = new Person("B", "B");
Person person3 = new Person("C", "A");
Person person4 = new Person("A", "D");
Person person5 = new Person("E", "E");
MutableSet personSet1 = Sets.mutable.with(person1, person2, person3);
MutableSet personSet2 = Sets.mutable.with(person2, person4, person5);
HashingStrategy hashingStrategy =
HashingStrategies.fromFunction(Person::getLastName);
```
1) Using `reject()`: Creates a new `Set` which contains all the elements which do *not* satisfy the `Predicate`.
```
@Test
public void reject()
{
MutableSet personHashingStrategySet = HashingStrategySets.mutable.withAll(
hashingStrategy, personSet2);
// reject creates a new copy
MutableSet rejectSet = personSet1.reject(personHashingStrategySet::contains);
Assert.assertEquals(Sets.mutable.with(person1, person3), rejectSet);
}
```
2) Using `removeIf()`: Mutates the original `Set` by *removing* the elements which satisfy the `Predicate`.
```
@Test
public void removeIfTest()
{
MutableSet personHashingStrategySet = HashingStrategySets.mutable.withAll(
hashingStrategy, personSet2);
// removeIf mutates the personSet1
personSet1.removeIf(personHashingStrategySet::contains);
Assert.assertEquals(Sets.mutable.with(person1, person3), personSet1);
}
```
**Answer before requirement from OP via comment:** Kept for reference if others might find it useful.
3) Using `Sets.differenceInto()` API available in Eclipse Collections:
In the code below, `set1` and `set2` are the two sets which use `Person`'s `equals()` and `hashCode()`. The `differenceSet` is a `UnifiedSetWithHashingStrategy` so, it uses the `lastNameHashingStrategy` to define uniqueness. Hence, even though `set2` does not contain `person3` however it has the same lastName as `person1` the `differenceSet` contains only `person1`.
```
@Test
public void differenceTest()
{
MutableSet differenceSet = Sets.differenceInto(
HashingStrategySets.mutable.with(hashingStrategy),
set1,
set2);
Assert.assertEquals(Sets.mutable.with(person1), differenceSet);
}
```
Person class common to both code blocks:
```
public class Person
{
private final String firstName;
private final String lastName;
public Person(String firstName, String lastName)
{
this.firstName = firstName;
this.lastName = lastName;
}
public String getFirstName()
{
return firstName;
}
public String getLastName()
{
return lastName;
}
@Override
public boolean equals(Object o)
{
if (this == o)
{
return true;
}
if (o == null || getClass() != o.getClass())
{
return false;
}
Person person = (Person) o;
return Objects.equals(firstName, person.firstName) &&
Objects.equals(lastName, person.lastName);
}
@Override
public int hashCode()
{
return Objects.hash(firstName, lastName);
}
}
```

<issue_start>username_0: I m making a small web/application to exercise what I m learning from Spring boot and ajax.
I have a web page where I have a form that have two date inputs 'start date' and 'end date' I wanted to send the user input to a RestController and to get a response that I should show in a empty div
here is what I have done till now
My Form :
```
Resrvation de salle
===================
[[#{homePage.envoyer}]]
```
Now I will show you my ajax script
```
$(document).ready(function () {
//alert("is loading");
$("#searchSalle").submit(function (event) {
//stop submit the form, we will post it manually.
event.preventDefault();
fire_serach_salle();
});
$("#send_mail").submit(function (event) {
//stop submit the form, we will post it manually.
event.preventDefault();
fire_send_mail();
});
});
function fire_serach_salle(){
var searchReserv = {};
searchReserv["dateDebutAnnee"] = $("#dateDebut").val().split('-')[0];
searchReserv["dateDebutMois"] = $("#dateDebut").val().split('-')[1];
searchReserv["dateDebutJour"] = $("#dateDebut").val().split('-')[2];
searchReserv["dateFinAnnee"] = $("#dateFin").val().split('-')[0];
searchReserv["dateFinMois"] = $("#dateFin").val().split('-')[1];
searchReserv["dateFinJour"] = $("#dateFin").val().split('-')[2];
$("#searchSalle").prop("disabled",true);
console.log(searchReserv);
$.ajax({
type: "POST",
contentType: "application/json",
url: "/homePage/reservation/search",
data: JSON.stringify(searchReserv),
dataType: 'json',
cache: false,
timeout: 900000,
success: function (result) {
if (result.answer === "DONE") {
/**/
var html ='<h2>Liste des salles </h2>';
html+='<ul class="w3-ul w3-hoverable">';
for(var i = 0 ;i<result.data.length;i++){
html += ' <li class="w3-display-container ">'+result.data[i].titre+'-'+result.data[i].id+'<span onclick="reserve('+result.data[i].id+')" class="w3-button w3-transparent w3-display-right w3-hover-green">reserver</span></li>';
}
html+='</ul>';
/**/
$("#salleList").html(html);
$("#searchSalle").prop("disabled",false);
}
}
});
}
```
now I will show my controller
```
@RestController
@PropertySource(ignoreResourceNotFound = true, value = "classpath:messages.properties")
public class HomePageController {
@RequestMapping(value = "/homePage/reservation/search", method = RequestMethod.POST)
public @ResponseBody
AjaxResponse doSearch(@RequestBody SearchReserv searchReserv, Model model) {
try {
System.out.println(searchReserv);
ArrayList response = new ArrayList<>();
response.add(new ReservationSearchResponse(Long.valueOf(0), "hello 0"));
response.add(new ReservationSearchResponse(Long.valueOf(1), "hello 1"));
return new AjaxResponse("DONE", response);
} catch (Exception e) {
e.printStackTrace();
return new AjaxResponse("BAD", null);
}
}
```
Finally my two classes AjaxResponse and SearcheReserv
```
public class AjaxResponse {
private String answer;
private Object data;
//geters setters and contructors
}
import org.springframework.stereotype.Component;
/**

@Component
public class SearchReserv {
private int dateDebutAnnee;
private int dateDebutMois;
private int dateDebutJour;
private int dateFinAnnee;
private int dateFinMois;
private int dateFinJour;
//geters setters and contructors
}
```
What I can't understand that I m using this way to implement a send mail using spring mail and it working fine
but in this one I still getting

<issue_start>username_0: I have a straightforward XPage that lets a user answer a question with a simple Yes/No/NA response using radio buttons. I have restyled the radio buttons to look like a bootstrap button group to make it visually more interesting for the user. If the user chooses "Fail" then they are informed that they need to do something else - easily done with a simple partial refresh to a div further down the page.
This all works fine.
The problem I'm having is that I'd like it so that when the user selects an option, I would like to add a new class of "active" to the selected option so that it highlights in a pretty colour. But for the life of me I can't get this to work and though I'm sure it's a straight forward problem, I can no longer see the wood for the trees.
My current (abridged) iteration of the radio button code is this:
```
XSP.partialRefreshPost('#{id:edit-result}');
```
This was attempting to do a chained partial refresh on the radio button container so that the EL would evaluate and apply/remove the 'active' style based on the document datasource ('item') value. I have also tried using dojo.addClass, dojo.removeClass, XSP.partialRefreshGet and other options. I don't mind what the solution is as long as it's efficient and works. I'd prefer not to move the actionAlert panel to within the same container as the radio buttons and I can't do a full page refresh because there are other fields which will lose their values.
Some notes:
* I'm not using a RadioGroup control because it outputs a table and I haven't got around to writing my own renderer for it yet. Single Radio button controls work fine for what I need them to do.
* I originally tried using the full Bootstrap solution of using "data-toggle='buttons'" ([source](https://getbootstrap.com/docs/3.3/javascript/#buttons)) which sorts out applying the "active" style fine but then, inevitably, prevents the partial refresh from working.
* the radio button styles are clearly not Bootstrap standard
Any assistance pointers or, preferably, working solutions would be appreciated.<issue_comment>username_1: Try using annotation **@RequestMapping(method=GET)** and share the result after that. It should resolve this issue.

<issue_start>username_0: I am trying to use `react-dates` with `redux-form`. Did a `render` thing for it. I have handled `text` `input` and `select` fields pretty much the same way. Those are working fine.
Getting a funky error on either `DateRangePicker` or even `SingleDatePicker`, which I cannot make sense of. Any ideas/suggestions are greatly appreciated.
Did a render component as:
```
const renderDateRangePicker = ({
input,
focusedInput,
onFocusChange,
startDatePlaceholderText,
endDatePlaceholderText
}) => (
input.onChange(start, end)}
onFocusChange={onFocusChange}
startDatePlaceholderText={startDatePlaceholderText}
endDatePlaceholderText={endDatePlaceholderText}
focusedInput={focusedInput}
startDate={(input.value && input.value.startDate) || null}
startDateId="startDateId"
endDateId="endDateId"
endDate={(input.value && input.value.endDate) || null}
minimumNights={0}
/>
)
```
My class is just a form as:
```
class ActivityForm extends Component {
// values: ['startDate', 'endDate']
state = {
focusedInput: null
}
onFocusChange(focusedInput) {
this.setState({ focusedInput });
}
render () {
const { focusedInput } = this.state
const { handleSubmit, teams } = this.props
return (
Save
)
}
}
export default reduxForm({ form: 'activity' })(ActivityForm)
```
For some reason, DateRangePicker causes a strange error: `Uncaught TypeError: Cannot read property 'createLTR' of undefined`.
What am I missing?<issue_comment>username_1: Try using annotation **@RequestMapping(method=GET)** and share the result after that. It should resolve this issue.

<issue_start>username_0: My Json is
```
{
Id: 1,
Name:'Alex',
ConnectedObjectName:'Obj',
ConnectedObjectId: 99
}
```
I want this JSON to be converted to the following object
```
Class Response
{
int Id,
string Name,
ConnectedObject Obj
}
Class ConnectedObject
{
string COName,
int COId
}
```
Is there a way to achieve this using DataContractJsonSerializer<issue_comment>username_1: Most serializers want the object and the data to share a layout - so most json serializers would want `ConnectedObjectName` and `ConnectedObjectId` to exist on the root object, not an inner object. Usually, if the data isn't a good "fit" for what you want to map it into, the best approach is to use a separate DTO model that matches the data and the serializer, then map from the DTO model to the *actual* model you want programatically, or using a tool like auto-mapper.
If you used the DTO approach, *just about any* JSON deserializer would be fine here. `Json.NET` is a good default. DataContractJsonSerializer would be *way way* down on my list of JSONserializers to consider.
Upvotes: 3 <issue_comment>username_2: To expand on what username_1 has said, most JSON serializers would expect your JSON to look like the following, which would map correctly to your classes:
```
{
"Id": 1,
"Name": "Alex",
"Obj" : {
"COName": "Obj",
"COId": 99
}
}
```
The way to get around this would be to read your JSON into an object that matches it, and then map it form that object to the object that you want:
Deserialize to this object:
```
class COJson {
public int Id;
public string Name;
public string ConnectedObjectName;
public int ConnectedObjectId;
}
```
Then map to this object:
```
class Response {
public int Id;
public string Name;
public ConnectedObject Obj;
}
class ConnectedObject {
public string COName;
public string COId;
}
```
Like this:
```
using(var stream = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
var serializer = new DataContractJsonSerializer(typeof(COJson));
var jsonDto = (COJson)ser.ReadObject(stream);
var dto = new Response(){
Id = jsonDto.Id,
Name = jsonDto.Name,
Obj = new ConnectedObject(){
COName = jsonDto.ConnectedObjectName,
COId = jsonDto.ConnectedObjectId
}
};
return dto;
}
```

```<issue_comment>username_1: The reason you are getting zero rows is because the only thing you do in `j` is print the outcome of the `summary` command.
Considering the following example data:
```
set.seed(2018)
dt <- data.table(bin = rep(c('A','B'), 5), val = rnorm(10,3,1))
```
Now when you do (like in your question):
```
s <- dt[, print(summary(val)), by = bin]
```
the summary statistics are printed to the console but it results in an empty *data.table*:

Removing the `print`-command doesn't help:

because `summary` returns a table-object which is treated a vector by `data.table`.
Instead of using `print`, you should use `as.list` to get the elements of `summary` as columns in a *data.table*:
```
s <- dt[, as.list(summary(val)), by = bin]
```
now the summary statistics are included in the resulting *data.table*:

Because the summary statistics are stored in the non-empty *data.table* `s`, you can write `s` to a file with for example `fwrite` (the fast write function the`data.table`-package).

**EDIT**
I tried to simplify my example, and I did an error by making it too simple. What I'm interested is an explanation for this error which is output by IntelliJ:
```

}
private static BiConsumer super T, ? super Throwable f2(Consumer super Throwable consumer)

@Test

{
BiConsumer super Integer, ? super Throwable action1 = f1(throwable -> { });
BiConsumer super Integer, ? super Throwable action2 = f2(throwable -> { }); // ERROR HERE
}

IntelliJ considers this an error because "inference variable T has incompatible bounds: equality constraints: T lower bounds: Integer".
But when compiling it, it's fine, no error. Is this an actually valid Java code and just a bug in IntelliJ? Thanks.<issue_comment>username_1: A `Consumer super Something` isn't a `Consumer`.
The compiler doesn't know that there are no producer methods on the `Consumer` class, so it stops you potentially using it as a producer.
As far as the type inference rules are concerned, there is no difference between `Consumer` and `List`, for example. So the same rule which stops you writing the following also stops you in what you are doing:
```
List super Integer c = Arrays.asList("");
List d = c; // Compiler error; let's pretend it works.
Integer i = d.get(0); // ClassCastException!
```

I suspect this is a bug in intellij. If I remove the variable declaration, and then select the expression and press `Ctrl`+`Alt`+`V` to extract a variable, it picks the following type:
```
BiConsumer super Object, ? super Throwable biConsumer = f2(throwable -> {});
```
which, despite just having picked itself, it highlights the lambda as an error.

<issue_start>username_0: Lets say I have a list with three arrays as following:
`[(1,2,0),(2,9,6),(2,3,6)]`
Is it possible I get the average by diving each "slot" of the arrays in the list.
For example:
`(1+2+2)/3, (2+0+9)/3, (0+6+6)/3`
and make it become new arraylist with only 3 integers.<issue_comment>username_1: Here are couple of ways you can do it.
```
data = [(1,2,0),(2,9,6),(2,3,6)]
avg_array = []
for tu in data:
avg_array.append(sum(tu)/len(tu))
print(avg_array)
```
using list comprehension
```
data = [(1,2,0),(2,9,6),(2,3,6)]
comp = [ sum(i)/len(i) for i in data]
print(comp)
```

Create an empty array. Loop through your current array and use the sum and len functions to calculate averages. Then append the average to your new array.
```
array = [(1,2,0),(2,9,6),(2,3,6)]
arraynew = []
for i in range(0,len(array)):
arraynew.append(sum(array[i]) / len(array[i]))
print arraynew
```
Upvotes: 0 <issue_comment>username_3: As you were told in the comments with `sum` and `len` it's pretty easy.
But in python I would do something like this, assuming you want to maintain decimal precision:
```
list = [(1, 2, 0), (2, 9, 6), (2, 3, 6)]
res = map(lambda l: round(float(sum(l)) / len(l), 2), list)
```
Output:
```
[1.0, 5.67, 3.67]
```
But as you said you wanted 3 `int`s in your question, would be like this:
```
res = map(lambda l: sum(l) / len(l), list)
```
Output:
```
[1, 5, 3]
```
Edit:
To sum the same index of each tuple, the most elegant method is the solution provided by @PatrickHaugh.
On the other hand, if you are not fond of list comprehensions and some built in functions as `zip` is, here's a little longer and less elegant version using a `for` loop:
```
arr = []
for i in range(0, len(list)):
arr.append(sum(l[i] for l in list) / len(list))
print(arr)
```
Output:
```
[1, 4, 4]
```
Upvotes: 0 <issue_comment>username_4: You can use [`zip`](https://docs.python.org/3/library/functions.html#zip) to associate all of the elements in each of the interior tuples by index
```
tups = [(1,2,0),(2,9,6),(2,3,6)]
print([sum(x)/len(x) for x in zip(*tups)])
# [1.6666666666666667, 4.666666666666667, 4.0]
```
You can also do something like `sum(x)//len(x)` or `round(sum(x)/len(x))` inside the list comprehension to get an integer.

Do I need to fetch something from additional repositories?
I am using Maven 3.3.9 and Java JDK version: 1.8.0\_111, from Oracle Corporation.

```<issue_comment>username_1: Have you fetched/updated recently? There were some issues with version numbers that broke the build recently: <https://github.com/eclipse/milo/issues/230>
They have been fixed on HEAD
Upvotes: 0 <issue_comment>username_2: The org.opcfoundation.\* sources are generated during the 'generate-sources' phase and placed in ../target/generated-sources. In Eclipse, you have to add this folder to the build-path.
Open the properties dialog for bsd-parser-core, open the build path folder and add the source folder.

<issue_start>username_0: I'm trying to replicate the output that jupyter uses for a pandas dataframe in their notebooks to html/css/js so that it's returnable by Flask `jsonify` as html that I later use in an AJAX call.
I found [this](https://stackoverflow.com/questions/38511373/change-the-color-of-text-within-a-pandas-dataframe-html-table-python-using-style), and [this](https://stackoverflow.com/questions/36897366/pandas-to-html-using-the-style-options-or-custom-css), which suggested using the pandas builtin style functionality rather than CSS hacks but i'm struggling to get the desired functionality:
```
def hover(hover_color="#add8e6"):
return dict(selector="tr:hover",
props=[("background-color", "%s" % hover_color)])
styles = [
hover(),
dict(selector="th", props=[("font-size", "125%"),
("text-align", "center"),
("padding", "5px 5px")]),
dict(selector="tr", props=[("text-align", "center")]),
dict(selector="caption", props=[("caption-side", "bottom")])
]
# creating some dummy data
index = pd.MultiIndex(levels=[['bar', 'baz', 'foo', 'qux'], ['one', 'two']],
labels=[[0, 0, 1, 1, 2, 2, 3, 3], [0, 1, 0, 1, 0, 1, 0, 1]],
names=['first', 'second'])
df = pd.DataFrame(data=np.random.randn(8), index=index)
# you'll see the html rendered bellow
df.style.set_table_styles(styles).set_caption("test").render()
```
Compared to jupyter notebooks, this is missing some default background color stripping, and the header shouldn't apply the hover class. The only way I can think to apply something on select elements would be to add `class=` or `id=` but the style functionality hides all that.
```html
#T\_479b61ba\_292a\_11e8\_86bf\_0ee09a5428a2 tr:hover { background-color: #add8e6; } #T\_479b61ba\_292a\_11e8\_86bf\_0ee09a5428a2 th { font-size: 150%; text-align: center; } #T\_479b61ba\_292a\_11e8\_86bf\_0ee09a5428a2 caption { caption-side: bottom; }
Hover to highlight.| | | 0 |

| bar | one | -0.0690895 |
| two | -0.518092 |
| baz | one | -0.163842 |

| foo | one | 1.22865 |
| two | 1.83947 |
| qux | one | 0.793328 |
| two | -0.723836 |
```<issue_comment>username_1: I've made a few changes to your code to get the functionality you want:
* Pandas dataframes are styled with two special HTML tags for tables, namely `thead` for the header and `tbody` for the body. We can use this to specify the highlighting behavior as body-only
* CSS has "even" and "odd" properties which you can use to add shading effects to tables.
* In order for hover to work with the background shading specified, it must be called last not first
**In Jupyter Notebook:**
```
import pandas as pd
import numpy as np
from IPython.display import HTML
def hover(hover_color="#add8e6"):
return dict(selector="tbody tr:hover",
props=[("background-color", "%s" % hover_color)])
styles = [
#table properties
dict(selector=" ",
props=[("margin","0"),
("font-family",'"Helvetica", "Arial", sans-serif'),
("border-collapse", "collapse"),
("border","none"),
("border", "2px solid #ccf")
]),
#header color - optional
dict(selector="thead",
props=[("background-color","#cc8484")
]),
#background shading
dict(selector="tbody tr:nth-child(even)",
props=[("background-color", "#fff")]),
dict(selector="tbody tr:nth-child(odd)",
props=[("background-color", "#eee")]),
#cell spacing
dict(selector="td",
props=[("padding", ".5em")]),
#header cell properties
dict(selector="th",
props=[("font-size", "125%"),
("text-align", "center")]),
#caption placement
dict(selector="caption",
props=[("caption-side", "bottom")]),
#render hover last to override background-color
hover()
]
html = (df.style.set_table_styles(styles)
.set_caption("Hover to highlight."))
html
```

**...but is it still beautiful when we output the HTML file??**
Yes. You can do some more CSS styling to get it just right (font-size, font-family, text-decoration, margin/padding, etc) but this gives you a start. See below:
```
print(html.render())
```
```html
#T\_3e73cfd2\_396c\_11e8\_9d70\_240a645b34fc {

I believe this includes all the CSS for notebook cell outputs, so you just need the table related parts (table, thead, tbody, th, etc) and tweak them to your liking. You still need to turn it in python, but to illustrate it works, here's the raw HTML
```html

Mi and di mandem
We haffi run from half of di gyal dem
So sweet, so sweet
Don't want mi children and ting'
Mi nuh ready fi all dem tings
So sweet, you're so sweet, yeah
Yeah, mi nuh ready fi all dem things yet
So sweet, so sweet, yeah
Yeah, I'm not ready fi all dem tings yet
I'm not ready fi all dem tings yet
She call me kid, kid, kid
My mama kiss her kid
She say mi tooth-tooth sweet
She say mi tooth-tooth sweet
Don't make me feel like I love you
Just 'cause I thought you was special
Won't make me feel like I love you
Baby, girl, I won't settle
I had dreams of fuckin' the baddest bitch
Last night I awoke up and I fucked the baddest bitch
I thought I would be ready when I seen her
When I was in the disco
I gotta keep it honest
Keep it real with you
Mi and di mandem
We haffi run from half of di gyal dem
So sweet, so sweet
Don't want mi children and tings
Mi nuh ready fi all dem tings
So sweet, you're so sweet
Mi nuh ready fi all dem tings yet
So sweet, so sweet
Mi and di mandem

So sweet, you're so sweet
Don't want mi children and tings
Mi nuh ready fi all dem tings
So sweet, you're so sweet
Mi nuh ready fi all dem tings
So sweet, so sweet
I strapped up 'cause they mapped up
'Cause I need to know where you are
Can't keep following these signs
'Cause you're lookin' for a sign, and I can't give you one
Start to feel like it's mad love
That's givin' your attraction, to me
Yeah, I just want you, nobody else, baby
I don't wanna get too far
It's just you that I want
When it's mi and di mandem
We haffi run from half of di gyal dem
So sweet, so sweet
Don't want mi children and tings
Mi nuh ready fi all dem tings
So sweet, you're so sweet
Mi nuh ready fi all dem tings yet
So sweet, so sweet
Mi and di mandem
We haffi run from half of di gyal dem
So sweet, so sweet
Don't want mi children and tings
Mi nuh ready fi all dem tings

What changes should I do to achieve the above? Thanks<issue_comment>username_1: Try this
```
Elements main = doc.select("div[class=container main-page]");
Elements row = main.select("div[class=row]");
Elements col = row.select("div[class=col-xs-12 col-lg-8 text-center]");
songMetaDataTextView.setText(Html.fromHtml(col.select("div").get(7).toString());
```
You have nested tags
```

So first you get container main-page then row and then col-xs-12 col-lg-8 text-center and then finally get the text using index 7

```
// Get the lyrics div element
Element lyricsDiv = document.select("div.main-page > div.row > div.col-xs-12").select("div").get(7);
// Get the html of the element and replace
and comments
String lyrics = lyricsDiv.html().replaceAll("
", "").replaceAll("", "");
```

<issue_start>username_0: Consider this variable
```
X = "1_2_3_4",
```
How to I get X into a binary string format?
So like this
```
<<"1_2_3_4">>
```
I'm getting all manner of errors trying to figure it out.
Thanks in advance,
Snelly.<issue_comment>username_1: Use the built in conversion function.
list\_to\_binary(X).

In case you are interested:
```
convert(L) ->
convert(L, <<>>).
convert([], Bin) ->
Bin;
convert([H|T], Bin) ->
convert(T, <>).
```

I think the reason that it's confusing is because sometimes the shell prints out a list as a string and sometimes it doesn't. In my opinion, things would be much clearer if the shell always output a list as a list unless you specifically requested a string.

<issue_start>username_0: On the subject of Anonymous classes, the Oracle documentation states that...
>
> They are like local classes except that they do not have a name. Use them if you need to use a local class only once
>
>
>
Now, given that local classes are (to my knowledge) classes defined within a method (or some other local construct) like the following...(where 'MyInterface' is an interface with an abstract 'test' method)
```
public void localTest(){
MyInterface mi = new MyInterface(){
@Override
public void test(){System.out.println("test");};
};
}
```
The above is OK and falls within the definition above, however, I can also define the following...
```
class MyClass{
MyInterface mi = new MyInterface(){
@Override
public void test(){System.out.println("test");};
};
}
```
This isn't within a method so isn't a 'Local' class and therefore doesn't fall within the above definition. Is there anywhere I can read about these types of anonymous classes (anonymous member classes if you will). What exactly are they if not anonymous classes as defined?<issue_comment>username_1: Local classes are defined [here](https://docs.oracle.com/javase/tutorial/java/javaOO/localclasses.html) as being defined in a *block*, rather than in a method. Your example is still an anonymous class. If you're in the process of learning, a note here is that you can actually replace the declaration with a lambda expression like so:
```
MyInterface mi = () -> System.out.println("test");
```
Also, anonymous classes are only described as being *like* local classes, meaning that the former is not necessarily a subset of the latter.
Upvotes: 0 <issue_comment>username_2: Both examples you show are anonymous classes. A true local class is a class definition in a method (or other code block), with an actual name (so, not anonymous). Given your example, an equivalent local class would be:
```
public void localTest(){
class LocalClass implements MyInterface {
@Override
public void test(){
System.out.println("test");
}
}
MyInterface mi = new LocalClass();
}
```
In my opinion you should hardly ever need a local class. I think I have only tried to use it once, to only quickly refactor it when I got a grip on what I actually needed.
The most important difference between local classes and anonymous classes is that you can reuse a local class within the same method (that is create multiple instances in the same method; without resorting to loops or lambdas).
Furthermore, as you actually have class definition, you can also define and call methods that aren't defined in the interface or super-class. Prior to Java 10 and the introduction of `var`, this was not possible with anonymous classes.
Other minor differences are that local classes can be abstract or final, and local classes can extend (and be extended by) other local classes, while an anonymous class is not final and cannot be abstract, but anonymous classes cannot be extended by other classes.
For more information regarding the difference between local classes and anonymous classes, see the Java Language Specification, specifically [14.3. Local Class Declarations](https://docs.oracle.com/javase/specs/jls/se9/html/jls-14.html#jls-14.3) and [15.9.5. Anonymous Class Declarations](https://docs.oracle.com/javase/specs/jls/se9/html/jls-15.html#jls-15.9.5) and related sections.

<issue_start>username_0: I need to test that a series of asynchronous functions are called in a particular order. Is there an easy way to do this?
An example of what I want to achieve below:
```
describe("Test ASYNC order", () => {
it("Calls in a particular order", () => {
const p1 = new Promise(resolve => setTimeout(resolve, 500));
const p2 = new Promise(resolve => setTimeout(resolve, 600));
const p3 = new Promise(resolve => setTimeout(resolve, 200));
/* How would I test that the order of the promises resolving is p3 then p1 then p2 ????? */
})
})
```<issue_comment>username_1: One way to do that is the following:
```
test('Calls in a particular order', async () => {
const res = [];
const storeRes = index => res.push(index);
const p1 = new Promise(resolve => setTimeout(resolve, 500)).then(() => storeRes(1));
const p2 = new Promise(resolve => setTimeout(resolve, 600)).then(() => storeRes(2));
const p3 = new Promise(resolve => setTimeout(resolve, 200)).then(() => storeRes(3));
await Promise.all([p1, p2, p3]);
expect(res).toEqual([3, 1, 2]);
});
```
It pushes values to an array after each promise, and once all of them have resolved, tests the order of the values in the `result` array against the expected order.
Upvotes: 4 [selected_answer]<issue_comment>username_2: You can create and use a Deferred object, as described in [Testing Promise Side Effects with Async/Await](https://rescale.com/testing-promise-side-effects-with-asyncawait/).
I would recommend this over using setTimeout, as unless you are controlling clocks with `jest.useFakeTimers`, setTimeout will increase the time it takes to execute your test.
```js
class Deferred {
constructor() {
this.promise = new Promise((resolve, reject) => {
this.resolve = resolve;
this.reject = reject;
});
}
}
test('Calls in a particular order', async () => {
const res = [];
const storeRes = index => res.push(index);
const d1 = new Deferred();
d1.promise.then(() => storeRes(1));
const d2 = new Deferred();
d2.promise.then(() => storeRes(2));
const d3 = new Deferred();
d3.promise.then(() => storeRes(3));
d3.resolve();
d1.resolve();
d2.resolve();
await Promise.all([d1.promise, d2.promise, d3.promise]);
expect(res).toEqual([3, 1, 2]);
});
```

<issue_start>username_0: I have 20 csv files. Each are unrelated. How do I combine them together into one xlsx file with 20 sheets, each named after the csv files.
```
$root = "C:\Users\abc\Desktop\testcsv"
$CSVfiles = Get-ChildItem -Path $root -Filter *.csv
$xlsx = "C:\Users\abc\Desktop\testxl.xlsx" #output location
$delimiter = "," #delimiter
#Create a excel
$xl=New-Object -ComObject Excel.Application
$xl.Visible=$true
#add a workbook
$wb=$xl.WorkBooks.add(1)
ForEach ($csv in $CSVfiles){
#name the worksheet
$ws=$wb.WorkSheets.item(1)
$ws.Name = [io.path]::GetFileNameWithoutExtension($csv)
$TxtConnector = ("TEXT;" + $csv)
$Connector = $ws.QueryTables.add($TxtConnector,$ws.Range("A1"))
$query = $ws.QueryTables.item($Connector.name)
$query.TextFileOtherDelimiter = $delimiter
$query.TextFileParseType = 1
$query.TextFileColumnDataTypes = ,1 * $ws.Cells.Columns.Count
$query.AdjustColumnWidth = 1
# Execute & delete the import query
$query.Refresh()
$query.Delete()
$wb.SaveAs($xlsx,51)
}
# Save & close the Workbook as XLSX.
$xl.Quit()
```<issue_comment>username_1: See below for a solution with uses the [`OpenText`](https://msdn.microsoft.com/en-us/vba/excel-vba/articles/workbooks-opentext-method-excel) method.
At least two things to note:
* I'm assuming your workbook creates a single sheet by default. if creates more than that, you will need to modify the script so that these additional sheets are deleted from the end result.
* The way you specify `TextFileColumnDataTypes` is quite clever. You will need to modify it and feed the array to the `FieldInfo` argument below. See the documentation linked above for the kind of array it is expecting.

```
$path="c:\path\to\folder" #target folder
cd $path;
$csvs = Get-ChildItem .\* -Include *.csv
$y=$csvs.Count
Write-Host "Detected the following CSV files: ($y)"
foreach ($csv in $csvs)
{
Write-Host " "$csv.Name
}
$outputfilename = $(get-date -f yyyyMMdd) + "_" + $env:USERNAME + "_combined-data.xlsx" #creates file name with date/username
Write-Host Creating: $outputfilename
$excelapp = new-object -comobject Excel.Application
$excelapp.sheetsInNewWorkbook = $csvs.Count
$xlsx = $excelapp.Workbooks.Add()
$sheet=1
foreach ($csv in $csvs)
{
$row=1
$column=1
$worksheet = $xlsx.Worksheets.Item($sheet)
$worksheet.Name = $csv.Name
$file = (Get-Content $csv)
foreach($line in $file)
{
$linecontents=$line -split ',(?!\s*\w+")'
foreach($cell in $linecontents)
{
$worksheet.Cells.Item($row,$column) = $cell
$column++
}
$column=1
$row++
}
$sheet++
}
$output = $path + "\" + $outputfilename
$xlsx.SaveAs($output)
$excelapp.quit()
cd \ #returns to drive root

Upvotes: 3 [selected_answer]<issue_comment>username_3: <https://stackoverflow.com/a/51094040/5995160> answer is too slow when dealing with csv's with a ton of data, I modified this solution to use <https://github.com/dfinke/ImportExcel>. This has greatly improved the performance of this task, at least for me.
```
Install-Module ImportExcel -scope CurrentUser
$csvs = Get-ChildItem .\* -Include *.csv
$csvCount = $csvs.Count
Write-Host "Detected the following CSV files: ($csvCount)"
foreach ($csv in $csvs) {
Write-Host " -"$csv.Name
}
$excelFileName = $(get-date -f yyyyMMdd) + "_" + $env:USERNAME + "_combined-data.xlsx"
Write-Host "Creating: $excelFileName"
foreach ($csv in $csvs) {
$csvPath = ".\" + $csv.Name
$worksheetName = $csv.Name.Replace(".csv","")
Write-Host " - Adding $worksheetName to $excelFileName"
Import-Csv -Path $csvPath | Export-Excel -Path $excelFileName -WorkSheetname $worksheetName
}
```
This solution assumes that the user has already changed directories to where all the csv's live.

<issue_start>username_0: I'm using lodash map in this way
```
const newCollection = _.map(
responseJson.OldCollection,
AddDetailsToSingleItems
);
```
having
```
function AddDetailsToSingleItems (item ) {
...
}
```
I ask you, please, what's the right syntax to pass a parameter to this function.
I'd like to have
```
function AddDetailsToSingleItems (item, myNewParam ) {
...
}
```
(note the `myNewParam`).
I don't kow how to tell to loadsh map to pass every single item to my function *and* to pass one more param when calling `AddDetailsToSingleItems`<issue_comment>username_1: You haven't explained where `myNewParam` is coming from, but I assume you have that data somewhere.
Lodash [map](https://lodash.com/docs/4.17.5#map) (just like normal JavaScript [map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map)) accepts a function as its second argument to be run on all elements of the supplied list. You can just pass an anonymous function:
```
_.map(
responseJson.OldCollection,
item => AddDetailsToSingleItems(item, myNewParam)
);
```
Upvotes: 4 [selected_answer]<issue_comment>username_2: You can create a function that knows the value of `myNewParam`, but only accepts the `item` parameter like this:
```
var myNewParam = 'param_value';
var AddDetailsFn = function(m) {
return function(item) {
return AddDetailsToSingleItems(item, m);
};
};
const newCollection = _.map(
responseJson.OldCollection,
AddDetailsFn(myNewParam)
);
```
This way, `_.map` only sees a function that takes a single parameter. The `AddDetailsFn` returns a function that takes a single parameter, but already has the value of `myNewParam` captured. You can also be more succinct with:
```
const newCollection = _.map(
responseJson.OldCollection,
function(item) { return AddDetailsToSingleItems(item, myNewParam); }
);
```

<issue_start>username_0: For example, I have JSON in response:
```
[{"id":1,"name":"text"},{"id":2,"name":"text"}]}
```
I want to verify if a response contains a custom object. For example:
```
Person(id=1, name=text)
```
I found solution:
```
Person[] persons = response.as(Person[].class);
assertThat(person, IsArrayContaining.hasItemInArray(expectedPerson));
```
I want to have something like this:
```
response.then().assertThat().body(IsArrayContaining.hasItemInArray(object));
```
Is there any solution for this?
Thanks in advance for your help!<issue_comment>username_1: The `body()` method accepts a path and a Hamcrest matcher (see the [javadocs](https://static.javadoc.io/io.rest-assured/rest-assured/3.0.6/io/restassured/response/ValidatableResponseOptions.html#body-java.lang.String-org.hamcrest.Matcher-java.lang.Object...-)).
So, you could do this:
```
response.then().assertThat().body("$", customMatcher);
```
For example:
```
// 'expected' is the serialised form of your Person
// this is a crude way of creating that serialised form
// you'll probably use whatever JSON de/serialisaiotn library is in use in your project
Map expected = new HashMap();
expected.put("id", 1);
expected.put("name", "text");
response.then().assertThat().body("$", Matchers.hasItem(expected));
```
Upvotes: 4 <issue_comment>username_2: In this case, you can also use json schema validation. By using this we don't need to set individual rules for JSON elements.
Have a look at [Rest assured schema validation](https://github.com/rest-assured/rest-assured/wiki/Usage#json-schema-validation)
```
get("/products").then().assertThat().body(matchesJsonSchemaInClasspath("products-schema.json"));
```

```
body("path.to.array",
hasItem(
allOf(
hasEntry("firstName", "test"),
hasEntry("lastName", "test")
)
)
)
```
