| .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 | ||

| .Description | ||
| Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the | ||
| given folder, and returns them in a map. | ||

| 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. | ||
