-.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:
