.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

.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.
