XMonad.Util.EntryHelper.Config

Configuration for EntryHelper

Documentation

data Config a

the configuration for EntryHelper.

• run should execute XMonad using a customized configuration.
• compile force should compile the source file and return a value which will lately be consumed by postCompile. force is just a hint about whether the compilation should be forced. compile is free to ignore it and do up-to-date check on its own.
• postCompile val should take action according to the val, usually produced by compile

Note that:

• compile should create a new process for compilation, as otherwise things like executeFile will replace the current process image with a new process image, make it impossible for postCompile to invoke.
• force is just a hint about whether the compilation should be forced. and compile is free to ignore it and do up-to-date checking on its own.
• don't remove the binary file when the compilation has failed, as XMonad restart relies on it.

Fields

run :: IO ()

the action for executing XMonad

compile :: Bool -> IO a

the action for compiling XMonad

postCompile :: a -> IO ()

the action after compiling XMonad

defaultConfig :: Config ExitCode

default config for xmonad-entryhelper, invokes xmonad with its default config file

withHelper :: IO () -> IO ()

withHelper e is the same as calling withCustomHelper with default compile and postCompile actions

Either of the following will work:

• replace your main entry with main = withHelper yourOldMain
• use main = withHelper (xmonad cfg) if you have only customized your XConfig

withCustomHelper :: Config a -> IO ()

simulates the way that XMonad handles its command line arguments.

• when called with no argument, the action in run will be used
• when called with a string prefixed with "--resume", or when called with "--replace", the action in run will be used
• when called with "--recompile" or "--restart", compile will be called. And postCompile will handle the results from compliation.
• additionally when called with "--restart" a restart request will be sent to the current XMonad instance after the compilation regardless of the compilation result.
