.Synopsis
Activate a Python virtual environment for the current PowerShell session.
.Description
Pushes the python executable for a virtual environment to the front of the
$Env:PATH environment variable and sets the prompt to signify that you are
in a Python virtual environment. Makes use of the command line switches as
well as the `pyvenv.cfg` file values present in the virtual environment.
.Parameter VenvDir
Path to the directory that contains the virtual environment to activate. The
default value for this is the parent of the directory that the Activate.ps1
script is located within.
.Parameter Prompt
The prompt prefix to display when this virtual environment is activated. By
default, this prompt is the name of the virtual environment folder (VenvDir)
surrounded by parentheses and followed by a single space (ie. '(.venv) ').
.Example
Activate.ps1
Activates the Python virtual environment that contains the Activate.ps1 script.
.Example
Activate.ps1 -Verbose
Activates the Python virtual environment that contains the Activate.ps1 script,
and shows extra information about the activation as it executes.
.Example
Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
Activates the Python virtual environment located in the specified location.
.Example
Activate.ps1 -Prompt "MyPython"
Activates the Python virtual environment that contains the Activate.ps1 script,
and prefixes the current prompt with the specified string (surrounded in
parentheses) while the virtual environment is active.
.Notes
On Windows, it may be required to enable this Activate.ps1 script by setting the
execution policy for the user. You can do this by issuing the following PowerShell
command:
PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
For more information on Execution Policies:

.Synopsis
Remove all shell session elements added by the Activate script, including the
addition of the virtual environment's Python executable from the beginning of
the PATH variable.
.Parameter NonDestructive
If present, do not remove this function from the global namespace for the
session.

.Description
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
given folder, and returns them in a map.
For each line in the pyvenv.cfg file, if that line can be parsed into exactly
two strings separated by `=` (with any amount of whitespace surrounding the =)
then it is considered a `key = value` line. The left hand string is the key,
the right hand is the value.
If the value starts with a `'` or a `"` then the first and last character is
stripped from the value before being captured.
.Parameter ConfigDir
Path to the directory that contains the `pyvenv.cfg` file.

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.

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'&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
>>> # 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>&#34;World&#34;</em>')

Key Features
============
- Supports both client and server side of HTTP protocol.
- Supports both client and server Web-Sockets out-of-the-box and avoids
Callback Hell.
- Provides Web-server with middlewares and plugable routing.
Getting started
===============
Client
------
To get something from the web:
.. code-block:: python
import aiohttp
import asyncio
async def main():
async with aiohttp.ClientSession() as session:
async with session.get('http://python.org') as response:
print("Status:", response.status)
print("Content-type:", response.headers['content-type'])
html = await response.text()
print("Body:", html[:15], "...")
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
This prints:
.. code-block::
Status: 200
Content-type: text/html; charset=utf-8
Body: <!doctype html> ...
Coming from `requests <https://requests.readthedocs.io/>`_ ? Read `why we need so many lines <https://aiohttp.readthedocs.io/en/latest/http_request_lifecycle.html>`_.
Server
------
An example using a simple server:
.. code-block:: python
# examples/server_simple.py
from aiohttp import web
async def handle(request):
name = request.match_info.get('name', "Anonymous")
text = "Hello, " + name
return web.Response(text=text)
async def wshandle(request):
ws = web.WebSocketResponse()
await ws.prepare(request)
async for msg in ws:
if msg.type == web.WSMsgType.text:
await ws.send_str("Hello, {}".format(msg.data))
elif msg.type == web.WSMsgType.binary:
await ws.send_bytes(msg.data)
elif msg.type == web.WSMsgType.close:
break
return ws
app = web.Application()
app.add_routes([web.get('/', handle),
web.get('/echo', wshandle),
web.get('/{name}', handle)])
if __name__ == '__main__':
web.run_app(app)

- Fix a problem with connection waiters that are never awaited.
`#4562 <https://github.com/aio-libs/aiohttp/issues/4562>`_

Reuse a protocol based on keepalive in headers is unreliable.
For example, uWSGI will not support keepalive even it serves a
HTTP 1.1 request, except explicitly configure uWSGI with a
``--http-keepalive`` option.
Servers designed like uWSGI could cause aiohttp intermittently
raise a ConnectionResetException when the protocol poll runs
out and some protocol is reused.

- Improve typing annotations for ``web.Request``, ``aiohttp.ClientResponse`` and
``multipart`` module.
`#4736 <https://github.com/aio-libs/aiohttp/issues/4736>`_
- Fix resolver task is not awaited when connector is cancelled
`#4795 <https://github.com/aio-libs/aiohttp/issues/4795>`_
