XMonad.Util.NamedActions

A wrapper for keybinding configuration that can list the available keybindings.

Note that xmonad>=0.11 has by default a list of the default keybindings bound to M-S-/ or M-?.

Usage:

Here is an example config that demonstrates the usage of sendMessage', mkNamedKeymap, addDescrKeys, and ^++^

import XMonad
import XMonad.Util.NamedActions
import XMonad.Util.EZConfig

main = xmonad $ addDescrKeys ((mod4Mask, xK_F1), xMessage) myKeys
                   def { modMask = mod4Mask }

myKeys c = (subtitle "Custom Keys":) $ mkNamedKeymap c $
   [("M-x a", addName "useless message" $ spawn "xmessage foo"),
    ("M-c", sendMessage' Expand)]
    ^++^
   [("<XF86AudioPlay>", spawn "mpc toggle" :: X ()),
    ("<XF86AudioNext>", spawn "mpc next")]

Using ^++^, you can combine bindings whose actions are X () as well as actions that have descriptions. However you cannot mix the two in a single list, unless each is prefixed with addName or noName.

If you don't like EZConfig, you can still use ^++^ with the basic XMonad keybinding configuration too.

Also note the unfortunate necessity of a type annotation, since spawn is too general.

sendMessage' :: (Message a, Show a) => a -> NamedAction

sendMessage but add a description that is show message. Note that not all messages have show instances.

spawn' :: String -> NamedAction

spawn but the description is the string passed

submapName :: HasName a => [((KeyMask, KeySym), a)] -> NamedAction

submap, but propagate the descriptions of the actions. Does this belong in XMonad.Actions.Submap?

addDescrKeys :: (HasName b1, HasName b) => ((KeyMask, KeySym), [((KeyMask, KeySym), NamedAction)] -> b) -> (XConfig Layout -> [((KeyMask, KeySym), b1)]) -> XConfig l -> XConfig l

Merge the supplied keys with defaultKeysDescr, also adding a keybinding to run an action for showing the keybindings.

addDescrKeys' :: HasName b => ((KeyMask, KeySym), [((KeyMask, KeySym), NamedAction)] -> b) -> (XConfig Layout -> [((KeyMask, KeySym), NamedAction)]) -> XConfig l -> XConfig l

Without merging with defaultKeysDescr

xMessage :: [((KeyMask, KeySym), NamedAction)] -> NamedAction

An action to send to addDescrKeys for showing the keybindings. See also showKm and showKmSimple

showKmSimple :: [((KeyMask, KeySym), NamedAction)] -> [[Char]]

showKm :: [((KeyMask, KeySym), NamedAction)] -> [String]

noName :: X () -> NamedAction

These are just the NamedAction constructor but with a more specialized type, so that you don't have to supply any annotations, for ex coercing spawn to X () from the more general MonadIO m => m ()

oneName :: (X (), String) -> NamedAction

addName :: String -> X () -> NamedAction

separator :: ((KeyMask, KeySym), NamedAction)

For a prettier presentation: keymask, keysym of 0 are reserved for this purpose: they do not happen, afaik, and keysymToString 0 would raise an error otherwise

subtitle :: String -> ((KeyMask, KeySym), NamedAction)

(^++^) :: (HasName b, HasName b1) => [(d, b)] -> [(d, b1)] -> [(d, NamedAction)]

Combine keymap lists with actions that may or may not have names

data NamedAction

An existential wrapper so that different types can be combined in lists, and maps
