+<#
+.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:

+Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the

+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.

+    -------

+
+    Notes
+    -----
+    In Python, objects can declare their textual representation using the
+    `__repr__` method. IPython expands on this idea and allows objects to declare
+    other, rich representations including:
+
+      - HTML
+      - JSON
+      - PNG
+      - JPEG
+      - SVG
+      - LaTeX
+
+    A single object can declare some or all of these representations; all are
+    handled by IPython's display system.
+
+    The main idea of the first approach is that you have to implement special
+    display methods when you define your class, one for each representation you
+    want to use. Here is a list of the names of the special methods and the
+    values they must return:
+
+      - `_repr_html_`: return raw HTML as a string, or a tuple (see below).
+      - `_repr_json_`: return a JSONable dict, or a tuple (see below).
+      - `_repr_jpeg_`: return raw JPEG data, or a tuple (see below).
+      - `_repr_png_`: return raw PNG data, or a tuple (see below).
+      - `_repr_svg_`: return raw SVG data as a string, or a tuple (see below).
+      - `_repr_latex_`: return LaTeX commands in a string surrounded by "$",
+                        or a tuple (see below).
+      - `_repr_mimebundle_`: return a full mimebundle containing the mapping
+                             from all mimetypes to data.
+                             Use this for any mime-type not listed above.
+
+    The above functions may also return the object's metadata alonside the
+    data.  If the metadata is available, the functions will return a tuple
+    containing the data and metadata, in that order.  If there is no metadata
+    available, then the functions will return the data only.
+
+    When you are directly writing your own classes, you can adapt them for
+    display in IPython by following the above approach. But in practice, you
+    often need to work with existing classes that you can't easily modify.
+
+    You can refer to the documentation on integrating with the display system in
+    order to register custom formatters for already existing types
+    (:ref:`integrating_rich_display`).
+
+    .. versionadded:: 5.4 display available without import
+    .. versionadded:: 6.1 display available without import
+
+    Since IPython 5.4 and 6.1 :func:`display` is automatically made available to
+    the user without import. If you are using display in a document that might
+    be used in a pure python context or with older version of IPython, use the
+    following import at the top of your file::

+"""Hooks for IPython.
+
+In Python, it is possible to overwrite any method of any object if you really
+want to.  But IPython exposes a few 'hooks', methods which are *designed* to
+be overwritten by users for customization purposes.  This module defines the
+default versions of all such hooks, which get used by IPython if not
+overridden by the user.
+
+Hooks are simple functions, but they should be declared with ``self`` as their
+first argument, because when activated they are registered into IPython as
+instance methods. The self argument will be the IPython running instance
+itself, so hooks have full access to the entire IPython object.
+
+If you wish to define a new hook and activate it, you can make an :doc:`extension
+</config/extensions/index>` or a :ref:`startup script <startup_files>`. For
+example, you could use a startup file like this::
+
+    import os
+
+    def calljed(self,filename, linenum):
+        "My editor hook calls the jed editor directly."
+        print("Calling my own editor, jed ...")
+        if os.system('jed +%d %s' % (linenum,filename)) != 0:
+            raise TryNext()
+
+    def load_ipython_extension(ip):
+        ip.set_hook('editor', calljed)
