============
... so better sign this
Various helpers to pass data to untrusted environments and to get it
back safe and sound. Data is cryptographically signed to ensure that a
token has not been tampered with.
It's possible to customize how data is serialized. Data is compressed as
needed. A timestamp can be added and verified automatically while
loading a token.
Installing
----------
Install and update using `pip`_:
.. code-block:: text
pip install -U itsdangerous
.. _pip: https://pip.pypa.io/en/stable/quickstart/
A Simple Example
----------------
Here's how you could generate a token for transmitting a user's id and
name between web requests.
.. code-block:: python
from itsdangerous import URLSafeSerializer
auth_s = URLSafeSerializer("secret key", "auth")
token = auth_s.dumps({"id": 5, "name": "itsdangerous"})
print(token)
# eyJpZCI6NSwibmFtZSI6Iml0c2Rhbmdlcm91cyJ9.6YP6T0BaO67XP--9UzTrmurXSmg
data = auth_s.loads(token)
print(data["name"])
# itsdangerous

By default Flask-SQLAlchemy will apply some backend-specific settings
to improve your experience with them.
As of SQLAlchemy 0.6 SQLAlchemy
will probe the library for native unicode support. If it detects
unicode it will let the library handle that, otherwise do that itself.
Sometimes this detection can fail in which case you might want to set
``use_native_unicode`` (or the ``SQLALCHEMY_NATIVE_UNICODE`` configuration
key) to ``False``. Note that the configuration key overrides the
value you pass to the constructor. Direct support for ``use_native_unicode``
and SQLALCHEMY_NATIVE_UNICODE are deprecated as of v2.4 and will be removed
in v3.0. ``engine_options`` and ``SQLALCHEMY_ENGINE_OPTIONS`` may be used
instead.
This class also provides access to all the SQLAlchemy functions and classes
from the :mod:`sqlalchemy` and :mod:`sqlalchemy.orm` modules. So you can
declare models like this::
class User(db.Model):
username = db.Column(db.String(80), unique=True)
pw_hash = db.Column(db.String(80))
You can still use :mod:`sqlalchemy` and :mod:`sqlalchemy.orm` directly, but
note that Flask-SQLAlchemy customizations are available only through an
instance of this :class:`SQLAlchemy` class. Query classes default to
:class:`BaseQuery` for `db.Query`, `db.Model.query_class`, and the default
query_class for `db.relationship` and `db.backref`. If you use these
interfaces through :mod:`sqlalchemy` and :mod:`sqlalchemy.orm` directly,
the default query class will be that of :mod:`sqlalchemy`.
.. admonition:: Check types carefully
Don't perform type or `isinstance` checks against `db.Table`, which
emulates `Table` behavior but is not a class. `db.Table` exposes the
`Table` interface, but is a function which allows omission of metadata.
The ``session_options`` parameter, if provided, is a dict of parameters
to be passed to the session constructor. See :class:`~sqlalchemy.orm.session.Session`
for the standard options.
The ``engine_options`` parameter, if provided, is a dict of parameters
to be passed to create engine. See :func:`~sqlalchemy.create_engine`
for the standard options. The values given here will be merged with and
override anything set in the ``'SQLALCHEMY_ENGINE_OPTIONS'`` config
variable or othewise set by this library.
.. versionadded:: 0.10
The `session_options` parameter was added.
.. versionadded:: 0.16
`scopefunc` is now accepted on `session_options`. It allows specifying
a custom function which will define the SQLAlchemy session's scoping.
.. versionadded:: 2.1
The `metadata` parameter was added. This allows for setting custom
naming conventions among other, non-trivial things.
The `query_class` parameter was added, to allow customisation
of the query class, in place of the default of :class:`BaseQuery`.
The `model_class` parameter was added, which allows a custom model
class to be used in place of :class:`Model`.
.. versionchanged:: 2.1
Utilise the same query class across `session`, `Model.query` and `Query`.
.. versionadded:: 2.4
The `engine_options` parameter was added.
.. versionchanged:: 2.4
The `use_native_unicode` parameter was deprecated.
.. versionchanged:: 2.4.3
``COMMIT_ON_TEARDOWN`` is deprecated and will be removed in
version 3.1. Call ``db.session.commit()`` directly instead.

Quick Tutorial
==============
*toml.loads* takes in a string containing standard TOML-formatted data and
returns a dictionary containing the parsed data.
.. code:: pycon
>>> import toml
>>> toml_string = """
... # This is a TOML document.
...
... title = "TOML Example"
...
... [owner]
... name = "Tom Preston-Werner"
... dob = 1979-05-27T07:32:00-08:00 # First class dates
...
... [database]
... server = "192.168.1.1"
... ports = [ 8001, 8001, 8002 ]
... connection_max = 5000
... enabled = true
...
... [servers]
...
... # Indentation (tabs and/or spaces) is allowed but not required
... [servers.alpha]
... ip = "10.0.0.1"
... dc = "eqdc10"
...
... [servers.beta]
... ip = "10.0.0.2"
... dc = "eqdc10"
...
... [clients]
... data = [ ["gamma", "delta"], [1, 2] ]
...
... # Line breaks are OK when inside arrays
... hosts = [
... "alpha",
... "omega"
... ]
... """
>>> parsed_toml = toml.loads(toml_string)
*toml.dumps* takes a dictionary and returns a string containing the
corresponding TOML-formatted data.
.. code:: pycon
>>> new_toml_string = toml.dumps(parsed_toml)
>>> print(new_toml_string)
title = "TOML Example"
[owner]
name = "Tom Preston-Werner"
dob = 1979-05-27T07:32:00Z
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002,]
connection_max = 5000
enabled = true
[clients]
data = [ [ "gamma", "delta",], [ 1, 2,],]
hosts = [ "alpha", "omega",]
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"
*toml.dump* takes a dictionary and a file descriptor and returns a string containing the
corresponding TOML-formatted data.
.. code:: pycon
>>> with open('new_toml_file.toml', 'w') as f:
... new_toml_string = toml.dump(parsed_toml, f)
>>> print(new_toml_string)
title = "TOML Example"

data = [ [ "gamma", "delta",], [ 1, 2,],]
hosts = [ "alpha", "omega",]
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"

Note
----
For Numpy users, by default the data types ``np.floatX`` will not be translated to floats by toml, but will instead be encoded as strings. To get around this, specify the ``TomlNumpyEncoder`` when saving your data.
.. code:: pycon
>>> import toml
>>> import numpy as np
>>> a = np.arange(0, 10, dtype=np.double)
>>> output = {'a': a}
>>> toml.dumps(output)
'a = [ "0.0", "1.0", "2.0", "3.0", "4.0", "5.0", "6.0", "7.0", "8.0", "9.0",]\n'
>>> toml.dumps(output, encoder=toml.TomlNumpyEncoder())
'a = [ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0,]\n'
API Reference
=============
``toml.load(f, _dict=dict)``
Parse a file or a list of files as TOML and return a dictionary.
:Args:
* ``f``: A path to a file, list of filepaths (to be read into single
object) or a file descriptor
* ``_dict``: The class of the dictionary object to be returned
:Returns:
A dictionary (or object ``_dict``) containing parsed TOML data
:Raises:
* ``TypeError``: When ``f`` is an invalid type or is a list containing
invalid types
* ``TomlDecodeError``: When an error occurs while decoding the file(s)
``toml.loads(s, _dict=dict)``
Parse a TOML-formatted string to a dictionary.
:Args:
* ``s``: The TOML-formatted string to be parsed
* ``_dict``: Specifies the class of the returned toml dictionary
:Returns:
A dictionary (or object ``_dict``) containing parsed TOML data
:Raises:
* ``TypeError``: When a non-string object is passed
* ``TomlDecodeError``: When an error occurs while decoding the
TOML-formatted string

Jinja
=====
Jinja is a fast, expressive, extensible templating engine. Special
placeholders in the template allow writing code similar to Python
syntax. Then the template is passed data to render the final document.
It includes:
- Template inheritance and inclusion.
- Define and import macros within templates.
- HTML templates can use autoescaping to prevent XSS from untrusted
user input.
- A sandboxed environment can safely render untrusted templates.
- AsyncIO support for generating templates and calling async
functions.
- I18N support with Babel.
- Templates are compiled to optimized Python code just-in-time and
cached, or can be compiled ahead-of-time.
- Exceptions point to the correct line in templates to make debugging
easier.
- Extensible filters, tests, functions, and even syntax.
Jinja's philosophy is that while application logic belongs in Python if
possible, it shouldn't make the template designer's job difficult by
restricting functionality too much.

Six is a Python 2 and 3 compatibility library. It provides utility functions
for smoothing over the differences between the Python versions with the goal of
writing Python code that is compatible on both Python versions. See the
documentation for more information on what is provided.
Six supports Python 2.7 and 3.3+. It is contained in only one Python
file, so it can be easily copied into your project. (The copyright and license
notice must be retained.)
Online documentation is at https://six.readthedocs.io/.
Bugs can be reported to https://github.com/benjaminp/six. The code can also
be found there.

The header or list which are safe to expose to the API of a CORS API
specification.

resource is accessed by allowed origins. The header(s) may be regular
expressions, case-sensitive strings, or else an asterisk.
Default : '*', allow all headers

3. App level configuration settings (e.g. CORS_*)
4. Default settings
Note: as it is possible for multiple regular expressions to match a

r"""The core component of Jinja is the `Environment`. It contains
important shared variables like configuration, filters, tests,
globals and others. Instances of this class may be modified if
they are not shared and if no template was loaded so far.
Modifications on environments after the first template was loaded
will lead to surprising effects and undefined behavior.
Here are the possible initialization parameters:
`block_start_string`
The string marking the beginning of a block. Defaults to ``'{%'``.
`block_end_string`
The string marking the end of a block. Defaults to ``'%}'``.
`variable_start_string`
The string marking the beginning of a print statement.
Defaults to ``'{{'``.
`variable_end_string`
The string marking the end of a print statement. Defaults to
``'}}'``.
`comment_start_string`
The string marking the beginning of a comment. Defaults to ``'{#'``.
`comment_end_string`
The string marking the end of a comment. Defaults to ``'#}'``.
`line_statement_prefix`
If given and a string, this will be used as prefix for line based
statements. See also :ref:`line-statements`.
`line_comment_prefix`
If given and a string, this will be used as prefix for line based
comments. See also :ref:`line-statements`.
.. versionadded:: 2.2
`trim_blocks`
If this is set to ``True`` the first newline after a block is
removed (block, not variable tag!). Defaults to `False`.
`lstrip_blocks`
If this is set to ``True`` leading spaces and tabs are stripped
from the start of a line to a block. Defaults to `False`.
`newline_sequence`
The sequence that starts a newline. Must be one of ``'\r'``,
``'\n'`` or ``'\r\n'``. The default is ``'\n'`` which is a
useful default for Linux and OS X systems as well as web
applications.
`keep_trailing_newline`
Preserve the trailing newline when rendering templates.
The default is ``False``, which causes a single newline,
if present, to be stripped from the end of the template.
.. versionadded:: 2.7
`extensions`
List of Jinja extensions to use. This can either be import paths
as strings or extension classes. For more information have a
look at :ref:`the extensions documentation <jinja-extensions>`.
`optimized`
should the optimizer be enabled? Default is ``True``.
`undefined`
:class:`Undefined` or a subclass of it that is used to represent
undefined values in the template.
`finalize`
A callable that can be used to process the result of a variable
expression before it is output. For example one can convert
``None`` implicitly into an empty string here.
`autoescape`
If set to ``True`` the XML/HTML autoescaping feature is enabled by
default. For more details about autoescaping see
:class:`~markupsafe.Markup`. As of Jinja 2.4 this can also
be a callable that is passed the template name and has to
return ``True`` or ``False`` depending on autoescape should be
enabled by default.
.. versionchanged:: 2.4
`autoescape` can now be a function
`loader`
The template loader for this environment.
`cache_size`
The size of the cache. Per default this is ``400`` which means
that if more than 400 templates are loaded the loader will clean
out the least recently used template. If the cache size is set to
``0`` templates are recompiled all the time, if the cache size is
``-1`` the cache will not be cleaned.
.. versionchanged:: 2.8
The cache size was increased to 400 from a low 50.
`auto_reload`
Some loaders load templates from locations where the template
sources may change (ie: file system or database). If
``auto_reload`` is set to ``True`` (default) every time a template is
requested the loader checks if the source changed and if yes, it
will reload the template. For higher performance it's possible to
disable that.
`bytecode_cache`
If set to a bytecode cache object, this object will provide a
cache for the internal Jinja bytecode so that templates don't
have to be parsed if they were not changed.
See :ref:`bytecode-cache` for more information.
`enable_async`
If set to true this enables async template execution which allows
you to take advantage of newer Python features. This requires
Python 3.6 or later.

the environment constructor but it's not possible to specify a loader.
Every template object has a few methods and members that are guaranteed
to exist. However it's important that a template object should be
considered immutable. Modifications on the object are not supported.
Template objects created from the constructor rather than an environment
do have an `environment` attribute that points to a temporary environment
that is probably shared with other templates created with the constructor
and compatible settings.

the minimal interface required.
Libraries compatible with this class:
- `cachelib <https://github.com/pallets/cachelib>`_
- `python-memcached <https://pypi.org/project/python-memcached/>`_
(Unfortunately the django cache interface is not compatible because it
does not support storing binary data, only unicode. You can however pass
the underlying cache client to the bytecode cache which is available
as `django.core.cache.cache._client`.)
The minimal interface for the client passed to the constructor is this:
.. class:: MinimalClientInterface
.. method:: set(key, value[, timeout])
Stores the bytecode in the cache. `value` is a string and
`timeout` the timeout of the key. If timeout is not provided
a default timeout or no timeout should be assumed, if it's
provided it's an integer with the number of seconds the cache
item should exist.
.. method:: get(key)
Returns the value for the cache key. If the item does not
exist in the cache the return value must be `None`.
The other arguments to the constructor are the prefix for all keys that
is added before the actual cache key and the timeout for the bytecode in
the cache system. We recommend a high (or no) timeout.
This bytecode cache does not support clearing of used items in the cache.
The clear method is a no-operation function.

system at the parser level. Custom extensions are bound to an environment
but may not store environment specific data on `self`. The reason for
this is that an extension can be bound to another environment (for
overlays) by creating a copy and reassigning the `environment` attribute.
As extensions are created by the environment they cannot accept any
arguments for configuration. One may want to work around that by using
a factory function, but that is not possible as extensions are identified
by their import name. The correct way to configure the extension is
storing the configuration values on the environment. Because this way the
environment ends up acting as central configuration storage the
attributes may clash which is why extensions have to ensure that the names
they choose for configuration are not too generic. ``prefix`` for example
is a terrible name, ``fragment_cache_prefix`` on the other hand is a good
name as includes the name of the extension (fragment cache).

default this function returns matches in babel style that means non string

allows Babel to figure out what you really meant if you are using

If you don't want that behavior set the `babel_style` parameter to `False`
which causes only strings to be returned and parameters are always stored
in tuples. As a consequence invalid gettext calls (calls without a single
string parameter or string parameters after non-string parameters) are
skipped.
This example explains the behavior:

>>> env = Environment()
>>> node = env.parse('{{ (_("foo"), _(), ngettext("foo", "bar", 42)) }}')

message)`` tuple, where:

* ``function`` is the name of the ``gettext`` function used (if the
string was extracted from embedded Python code), and
* ``message`` is the string itself (a ``unicode`` object, or a tuple
of ``unicode`` objects for functions with multiple string arguments).
This extraction function operates on the AST and is because of that unable
to extract any comments. For comment support you have to use the babel
extraction interface or extract comments yourself.

pycodestyle is a tool to check your Python code against some of the style
conventions in `PEP 8`_.
.. _PEP 8: http://www.python.org/dev/peps/pep-0008/
.. note::
This package used to be called ``pep8`` but was renamed to ``pycodestyle``
to reduce confusion. Further discussion can be found `in the issue where
Guido requested this
change <https://github.com/PyCQA/pycodestyle/issues/466>`_, or in the
lightning talk at PyCon 2016 by @IanLee1521:
`slides <https://speakerdeck.com/ianlee1521/pep8-vs-pep-8>`_
`video <https://youtu.be/PulzIT8KYLk?t=36m>`_.
Features
--------
* Plugin architecture: Adding new checks is easy.
* Parseable output: Jump to error location in your editor.
* Small: Just one Python file, requires only stdlib. You can use just
the ``pycodestyle.py`` file for this purpose.
* Comes with a comprehensive test suite.
Installation
------------
You can install, upgrade, and uninstall ``pycodestyle.py`` with these commands::
$ pip install pycodestyle
$ pip install --upgrade pycodestyle
$ pip uninstall pycodestyle
There's also a package for Debian/Ubuntu, but it's not always the
latest version.
Example usage and output
------------------------
::
$ pycodestyle --first optparse.py
optparse.py:69:11: E401 multiple imports on one line
optparse.py:77:1: E302 expected 2 blank lines, found 1
optparse.py:88:5: E301 expected 1 blank line, found 0
optparse.py:222:34: W602 deprecated form of raising exception
optparse.py:347:31: E211 whitespace before '('
optparse.py:357:17: E201 whitespace after '{'
optparse.py:472:29: E221 multiple spaces before operator
optparse.py:544:21: W601 .has_key() is deprecated, use 'in'
You can also make ``pycodestyle.py`` show the source code for each error, and
even the relevant text from PEP 8::
$ pycodestyle --show-source --show-pep8 testsuite/E40.py
testsuite/E40.py:2:10: E401 multiple imports on one line
import os, sys
^
Imports should usually be on separate lines.
Okay: import os\nimport sys
E401: import sys, os
Or you can display how often each error was found::
$ pycodestyle --statistics -qq Python-2.5/Lib
232 E201 whitespace after '['
599 E202 whitespace before ')'
631 E203 whitespace before ','
842 E211 whitespace before '('
2531 E221 multiple spaces before operator
4473 E301 expected 1 blank line, found 0
4006 E302 expected 2 blank lines, found 1
165 E303 too many blank lines (4)
325 E401 multiple imports on one line
3615 E501 line too long (82 characters)
612 W601 .has_key() is deprecated, use 'in'
1188 W602 deprecated form of raising exception

of a physical line. (Issue #268)
1.5.2 (2014-04-04)
------------------
Changes:
* Distribute a universal wheel file.
Bug fixes:
* Report correct line number for E303 with comments. (Issue #60)

------------------
Bug fixes:
* Fix a crash with E125 on multi-line strings. (Issue #263)
1.5 (2014-03-26)
----------------
Changes:
* Report E129 instead of E125 for visually indented line with same
indent as next logical line. (Issue #126)
* Report E265 for space before block comment. (Issue #190)
* Report E713 and E714 when operators ``not in`` and ``is not`` are
recommended. (Issue #236)

consistent within the same continuation block. It helps when
error E121 or E126 is in the ``ignore`` list.
* Report E126 instead of E121 when the continuation line is hanging
with extra indentation, even if indentation is not a multiple of 4.
Bug fixes:
* Allow the checkers to report errors on empty files. (Issue #240)
* Fix ignoring too many checks when ``--select`` is used with codes
declared in a flake8 extension. (Issue #216)
* Fix regression with multiple brackets. (Issue #214)

* Fix a false positive E126 when indenting with tabs. (Issue #204)
* Fix behaviour when ``exclude`` is in the configuration file and
the current directory is not the project directory. (Issue #247)
* The logical checks can return ``None`` instead of an empty iterator.
(Issue #250)
* Do not report multiple E101 if only the first indentation starts
with a tab. (Issue #237)
* Fix a rare false positive W602. (Issue #34)
1.4.6 (2013-07-02)
------------------
Changes:
* Honor ``# noqa`` for errors E711 and E712. (Issue #180)
* When both a ``tox.ini`` and a ``setup.cfg`` are present in the project
directory, merge their contents. The ``tox.ini`` file takes
precedence (same as before). (Issue #182)
* Give priority to ``--select`` over ``--ignore``. (Issue #188)
* Compare full path when excluding a file. (Issue #186)
* New option ``--hang-closing`` to switch to the alternative style of
closing bracket indentation for hanging indent. Add error E133 for
closing bracket which is missing indentation. (Issue #103)
* Accept both styles of closing bracket indentation for hanging indent.
Do not report error E123 in the default configuration. (Issue #103)
Bug fixes:
* Do not crash when running AST checks and the document contains null bytes.
(Issue #184)
* Correctly report other E12 errors when E123 is ignored. (Issue #103)
* Fix false positive E261/E262 when the file contains a BOM. (Issue #193)

* Fix false positive E121 with multiple brackets. (Issue #203)
1.4.5 (2013-03-06)
------------------
* When no path is specified, do not try to read from stdin. The feature
was added in 1.4.3, but it is not supported on Windows. Use ``-``
filename argument to read from stdin. This usage is supported
since 1.3.4. (Issue #170)
* Do not require ``setuptools`` in setup.py. It works around an issue
with ``pip`` and Python 3. (Issue #172)
* Add ``__pycache__`` to the ignore list.
* Change misleading message for E251. (Issue #171)
* Do not report false E302 when the source file has a coding cookie or a
comment on the first line. (Issue #174)
* Reorganize the tests and add tests for the API and for the command line
usage and options. (Issues #161 and #162)
* Ignore all checks which are not explicitly selected when ``select`` is
passed to the ``StyleGuide`` constructor.
1.4.4 (2013-02-24)
------------------

* Allow changing the ``checker_class`` for the ``StyleGuide``.
1.4.2 (2013-02-10)
------------------
* Support AST checkers provided by third-party applications.
* Register new checkers with ``register_check(func_or_cls, codes)``.
* Allow constructing a ``StyleGuide`` with a custom parser.
* Accept visual indentation without parenthesis after the ``if``
statement. (Issue #151)
* Fix UnboundLocalError when using ``# noqa`` with continued lines.
(Issue #158)
* Re-order the lines for the ``StandardReport``.
* Expand tabs when checking E12 continuation lines. (Issue #155)
* Refactor the testing class ``TestReport`` and the specific test
functions into a separate test module.
1.4.1 (2013-01-18)
------------------
* Allow sphinx.ext.autodoc syntax for comments. (Issue #110)
* Report E703 instead of E702 for the trailing semicolon. (Issue #117)
* Honor ``# noqa`` in addition to ``# nopep8``. (Issue #149)

1.4 (2012-12-22)
----------------
* Report E226 instead of E225 for optional whitespace around common
operators (``*``, ``**``, ``/``, ``+`` and ``-``). This new error
code is ignored in the default configuration because PEP 8 recommends
to "use your own judgement". (Issue #96)
* Lines with a ``# nopep8`` at the end will not issue errors on line
length E501 or continuation line indentation E12*. (Issue #27)
* Fix AssertionError when the source file contains an invalid line
ending ``"\r\r\n"``. (Issue #119)
* Read the ``[pep8]`` section of ``tox.ini`` or ``setup.cfg`` if present.
(Issue #93 and #141)
* Add the Sphinx-based documentation, and publish it
on https://pycodestyle.readthedocs.io/. (Issue #105)
1.3.4 (2012-12-18)
------------------

do not imply ``--first``. (Issue #89)
* Add E902 for IO errors. (Issue #87)
* Fix false positive for E121, and missed E124. (Issue #92)
* Set a sensible default path for config file on Windows. (Issue #95)

* Show the enforced ``max-line-length`` in the error message. (Issue #86)
1.3.1 (2012-06-18)
------------------
* Explain which configuration options are expected. Accept and recommend
the options names with hyphen instead of underscore. (Issue #82)
* Do not read the user configuration when used as a module
(except if ``config_file=True`` is passed to the ``StyleGuide`` constructor).
* Fix wrong or missing cases for the E12 series.
* Fix cases where E122 was missed. (Issue #81)
1.3 (2012-06-15)
----------------
.. warning::
The internal API is backwards incompatible.
* Remove global configuration and refactor the library around
a ``StyleGuide`` class; add the ability to configure various
reporters. (Issue #35 and #66)
* Read user configuration from ``~/.config/pep8``
and local configuration from ``./.pep8``. (Issue #22)
* Fix E502 for backslash embedded in multi-line string. (Issue #68)
* Fix E225 for Python 3 iterable unpacking (PEP 3132). (Issue #72)
* Enable the new checkers from the E12 series in the default
configuration.
* Suggest less error-prone alternatives for E712 errors.
* Rewrite checkers to run faster (E22, E251, E27).

closing brackets).
* Fix E127 and E128 for continuation line indentation. (Issue #74)
* New option ``--format`` to customize the error format. (Issue #23)
* New option ``--diff`` to check only modified code. The unified
diff is read from STDIN. Example: ``hg diff | pep8 --diff``

* Correctly report the count of failures and set the exit code to 1
when the ``--doctest`` or the ``--testsuite`` fails.
* Correctly detect the encoding in Python 3. (Issue #69)
* Drop support for Python 2.3, 2.4 and 3.0. (Issue #78)
1.2 (2012-06-01)
----------------
* Add E121 through E128 for continuation line indentation. These
checks are disabled by default. If you want to force all checks,
use switch ``--select=E,W``. Patch by Sam Vilain. (Issue #64)
* Add E721 for direct type comparisons. (Issue #47)
* Add E711 and E712 for comparisons to singletons. (Issue #46)
* Fix spurious E225 and E701 for function annotations. (Issue #29)
* Add E502 for explicit line join between brackets.
* Fix E901 when printing source with ``--show-source``.
* Report all errors for each checker, instead of reporting only the
first occurrence for each line.
* Option ``--show-pep8`` implies ``--first``.
1.1 (2012-05-24)
----------------
* Add E901 for syntax errors. (Issues #63 and #30)
* Add E271, E272, E273 and E274 for extraneous whitespace around

----------------
* Fix W602 ``raise`` to handle multi-char names. (Issue #53)
0.7.0 (2012-03-26)
------------------
* Now ``--first`` prints only the first occurrence of each error.
The ``--repeat`` flag becomes obsolete because it is the default
behaviour. (Issue #6)
* Allow specifying ``--max-line-length``. (Issue #36)
* Make the shebang more flexible. (Issue #26)

with fewer test files. Read the ``run_tests`` docstring for details
about the syntax.
* Fix E225: accept ``print >>sys.stderr, "..."`` syntax.
* Fix E501 for lines containing multibyte encoded characters. (Issue #7)
* Fix E221, E222, E223, E224 not detected in some cases. (Issue #16)
* Fix E211 to reject ``v = dic['a'] ['b']``. (Issue #17)
* Exit code is always 1 if any error or warning is found. (Issue #10)
* ``--ignore`` checks are now really ignored, especially in
conjunction with ``--count``. (Issue #8)
* Blank lines with spaces yield W293 instead of W291: some developers
want to ignore this warning and indent the blank lines to paste their
code easily in the Python interpreter.
* Fix E301: do not require a blank line before an indented block. (Issue #14)
* Fix E203 to accept NumPy slice notation ``a[0, :]``. (Issue #13)
* Performance improvements.
* Fix decoding and checking non-UTF8 files in Python 3.
* Fix E225: reject ``True+False`` when running on Python 3.

- lambda function with argument unpacking or keyword defaults.
* Reserve "2 blank lines" for module-level logical blocks. (E303)
* Allow multi-line comments. (E302, issue #10 [1]_)

MarkupSafe
==========
MarkupSafe implements a text object that escapes characters so it is
safe to use in HTML and XML. Characters that have special meanings are
replaced so that they display as the actual characters. This mitigates
injection attacks, meaning untrusted user input can safely be displayed
on a page.
Installing
----------
Install and update using `pip`_:
.. code-block:: text
pip install -U MarkupSafe
.. _pip: https://pip.pypa.io/en/stable/quickstart/
Examples
--------
.. code-block:: pycon
>>> from markupsafe import Markup, escape
>>> # escape replaces special characters and wraps in Markup
>>> escape('<script>alert(document.cookie);</script>')
Markup(u'<script>alert(document.cookie);</script>')
>>> # wrap in Markup to mark text "safe" and prevent escaping
>>> Markup('<strong>Hello</strong>')
Markup('<strong>hello</strong>')
>>> escape(Markup('<strong>Hello</strong>'))
Markup('<strong>hello</strong>')
>>> # Markup is a text subclass (str on Python 3, unicode on Python 2)
>>> # methods and operators escape their arguments
>>> template = Markup("Hello <em>%s</em>")
>>> template % '"World"'
Markup('Hello <em>"World"</em>')

"""
werkzeug.serving
~~~~~~~~~~~~~~~~
There are many ways to serve a WSGI application. While you're developing
it you usually don't want a full blown webserver like Apache but a simple
standalone one. From Python 2.5 onwards there is the `wsgiref`_ server in
the standard library. If you're using older versions of Python you can
download the package from the cheeseshop.
However there are some caveats. Sourcecode won't reload itself when
changed and each time you kill the server using ``^C`` you get an
`KeyboardInterrupt` error. While the latter is easy to solve the first
one can be a pain in the ass in some situations.
The easiest way is creating a small ``start-myproject.py`` that runs the
application::
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from myproject import make_app
from werkzeug.serving import run_simple
app = make_app(...)
run_simple('localhost', 8080, app, use_reloader=True)
You can also pass it a `extra_files` keyword argument with a list of
additional files (like configuration files) you want to observe.
For bigger applications you should consider using `click`
(http://click.pocoo.org) instead of a simple start file.

"""Start a WSGI application. Optional features include a reloader,

This function has a command-line interface too::
python -m werkzeug.serving --help
.. versionadded:: 0.5
`static_files` was added to simplify serving of static files as well
as `passthrough_errors`.
.. versionadded:: 0.6
support for SSL was added.
.. versionadded:: 0.8
Added support for automatically loading a SSL context from certificate
file and private key.
.. versionadded:: 0.9
Added command-line interface.
.. versionadded:: 0.10
Improved the reloader and added support for changing the backend
through the `reloader_type` parameter. See :ref:`reloader`
for more information.

Bind to a Unix socket by passing a path that starts with
``unix://`` as the ``hostname``.
:param hostname: The host to bind to, for example ``'localhost'``.
If the value is a path that starts with ``unix://`` it will bind
to a Unix socket instead of a TCP socket..
:param port: The port for the server. eg: ``8080``
:param application: the WSGI application to execute
:param use_reloader: should the server automatically restart the python
process if modules were changed?
:param use_debugger: should the werkzeug debugging system be used?
:param use_evalex: should the exception evaluation feature be enabled?
:param extra_files: a list of files the reloader should watch
additionally to the modules. For example configuration
files.
:param reloader_interval: the interval for the reloader in seconds.
:param reloader_type: the type of reloader to use. The default is
auto detection. Valid values are ``'stat'`` and
``'watchdog'``. See :ref:`reloader` for more
information.
:param threaded: should the process handle each request in a separate
thread?
:param processes: if greater than 1 then handle each request in a new process
up to this maximum number of concurrent processes.
:param request_handler: optional parameter that can be used to replace
the default one. You can use this to replace it
with a different
:class:`~BaseHTTPServer.BaseHTTPRequestHandler`
subclass.
:param static_files: a list or dict of paths for static files. This works
exactly like :class:`SharedDataMiddleware`, it's actually
just wrapping the application in that middleware before
serving.
:param passthrough_errors: set this to `True` to disable the error catching.
This means that the server will die on errors but
it can be useful to hook debuggers in (pdb etc.)
:param ssl_context: an SSL context for the connection. Either an
:class:`ssl.SSLContext`, a tuple in the form
``(cert_file, pkey_file)``, the string ``'adhoc'`` if
the server should automatically create one, or ``None``
to disable SSL (which is the default).
