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: https://go.microsoft.com/fwlink/?LinkID=135170 #> Param( [Parameter(Mandatory = $false)] [String] $VenvDir, [Parameter(Mandatory = $false)] [String] $Prompt ) <# Function declarations --------------------------------------------------- #> <# .Synopsis Remove all shell session elements added by the Activate script, including the addition of the virtual environment's Python executable from the beginning of the PATH variable. .Parameter NonDestructive If present, do not remove this function from the global namespace for the session. #> function global:deactivate ([switch]$NonDestructive) { # Revert to original values # The prior prompt: if (Test-Path -Path Function:_OLD_VIRTUAL_PROMPT) { Copy-Item -Path Function:_OLD_VIRTUAL_PROMPT -Destination Function:prompt Remove-Item -Path Function:_OLD_VIRTUAL_PROMPT } # The prior PYTHONHOME: if (Test-Path -Path Env:_OLD_VIRTUAL_PYTHONHOME) { Copy-Item -Path Env:_OLD_VIRTUAL_PYTHONHOME -Destination Env:PYTHONHOME Remove-Item -Path Env:_OLD_VIRTUAL_PYTHONHOME } # The prior PATH: if (Test-Path -Path Env:_OLD_VIRTUAL_PATH) { Copy-Item -Path Env:_OLD_VIRTUAL_PATH -Destination Env:PATH Remove-Item -Path Env:_OLD_VIRTUAL_PATH } # Just remove the VIRTUAL_ENV altogether: if (Test-Path -Path Env:VIRTUAL_ENV) { Remove-Item -Path env:VIRTUAL_ENV } # Just remove the _PYTHON_VENV_PROMPT_PREFIX altogether: if (Get-Variable -Name "_PYTHON_VENV_PROMPT_PREFIX" -ErrorAction SilentlyContinue) { Remove-Variable -Name _PYTHON_VENV_PROMPT_PREFIX -Scope Global -Force } # Leave deactivate function in the global namespace if requested: if (-not $NonDestructive) { Remove-Item -Path function:deactivate } } <# .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.

The constructor parameters determine the builder's behaviour when called upon to create a virtual environment. By default, the builder makes the system (global) site-packages dir *un*available to the created environment. If invoked using the Python -m option, the default is to use copying on Windows platforms but symlinks elsewhere. If instantiated some other way, the default is to *not* use symlinks. :param system_site_packages: If True, the system (global) site-packages dir is available to created environments. :param clear: If True, delete the contents of the environment directory if it already exists, before environment creation. :param symlinks: If True, attempt to symlink rather than copy files into virtual environment. :param upgrade: If True, upgrade an existing virtual environment. :param with_pip: If True, ensure pip is installed in the virtual environment :param prompt: Alternative terminal prefix for the environment.

The constructor parameters determine the builder's behaviour when called upon to create a virtual environment. By default, the builder makes the system (global) site-packages dir *un*available to the created environment. If invoked using the Python -m option, the default is to use copying on Windows platforms but symlinks elsewhere. If instantiated some other way, the default is to *not* use symlinks. :param system_site_packages: If True, the system (global) site-packages dir is available to created environments. :param clear: If True, delete the contents of the environment directory if it already exists, before environment creation. :param symlinks: If True, attempt to symlink rather than copy files into virtual environment. :param upgrade: If True, upgrade an existing virtual environment. :param with_pip: If True, ensure pip is installed in the virtual environment :param prompt: Alternative terminal prefix for the environment.
