:py:mod:`activate`
==================

.. py:module:: conda.activate

.. autoapi-nested-parse::

   Conda activate and deactivate logic.

   Implementation for all shell interface logic exposed via
   `conda shell.* [activate|deactivate|reactivate|hook|commands]`. This includes a custom argument
   parser, an abstract shell class, and special path handling for Windows.

   See conda.cli.main.main_sourced for the entry point into this module.

          .. if you pass and set any other variable to None, then it
          emits it to the dict with a value of None.

.. py:function:: _build_activator_cls(shell)

   Dynamically construct the activator class.

   Detect the base activator and any number of formatters (appended using '+' to the base name).
   For example, `posix+json` (as in `conda shell.posix+json activate`) would use the
   `PosixActivator` base class and add the `JSONFormatMixin`.
