XMonad.Util.ActionCycle
Contents
Description
This module provides a way to have "cycling" actions.
This means that you can define an X () action that cycles through a list of actions,
advancing every time it is executed.
This may for exapmle be useful for toggle-style keybindings.
Synopsis
- cycleAction :: String -> [X ()] -> X ()
- cycleActionWithResult :: String -> NonEmpty (X a) -> X a
Usage
You can use this module to implement cycling key-bindings by importing ActionCycle
import XMonad.Util.ActionCycle
and then creating a keybinding as follows:
((mod1Mask, xK_t), cycleAction "cycleActions" [ spawn "commmand1", spawn "command2", spawn "command3" ])
Note that the name given to cycleAction must be a unique action per cycle.
Arguments
| :: String | Unique name for this action. May be any arbitrary, unique string. |
| -> [X ()] | List of actions that will be cycled through. |
| -> X () |
Generate an X () action that cycles through a list of actions,
advancing every time the action is called.
cycleActionWithResult Source #
Arguments
| :: String | Unique name for this action. May be any arbitrary, unique string. |
| -> NonEmpty (X a) | Non-empty List of actions that will be cycled through. |
| -> X a |
Another version of cycleAction that returns the result of the actions.
To allow for this, we must make sure that the list of actions is non-empty.
