Commands
=========

.. module:: alot.commands

User actions are represented by :class:`Command` objects that can then be triggered by
:meth:`alot.ui.UI.apply_command`.
Command-line strings given by the user via the prompt or key bindings can be translated to
:class:`Command` objects using :func:`alot.commands.commandfactory`.
Specific actions are defined as subclasses of :class:`Command` and can be registered
to a global command pool using the :class:`registerCommand` decorator.

.. Note::

    that the return value
    of :func:`commandfactory` depends on the current *mode* the user interface is in.
    The mode identifier is a string that is uniquely defined by the currently focuses
    :class:`~alot.buffers.Buffer`.

.. note::

    The names of the commands available to the user in any given mode do not correspond
    one-to-one to these subclasses. You can register a Command multiple times under different
    names, with different forced constructor parameters and so on. See for instance the
    definition of BufferFocusCommand in 'commands/globals.py'::

        @registerCommand(MODE, 'bprevious', forced={'offset': -1},
                         help='focus previous buffer')
        @registerCommand(MODE, 'bnext', forced={'offset': +1},
                         help='focus next buffer')
        class BufferFocusCommand(Command):
            def __init__(self, buffer=None, offset=0, **kwargs):
            ...
