XMonad.Util.SpawnOnce

A module for spawning a command once, and only once. Useful to start status bars and make session settings inside startupHook. See also XMonad.Util.SessionStart for a different and more flexible way to run commands only on first startup.

Documentation

spawnOnce :: String -> X ()

The first time spawnOnce is executed on a particular command, that command is executed. Subsequent invocations for a command do nothing.

SpawnOn helpers

These functions combine spawnOnce with their relatives in XMonad.Actions.SpawnOn. You must add manageSpawn to your manageHook for them to work, as with SpawnOn.

manageSpawn :: ManageHook

Provides a manage hook to react on process spawned with spawnOn, spawnHere etc.

spawnOnOnce :: WorkspaceId -> String -> X ()

Like spawnOnce but launches the application on the given workspace.

spawnNOnOnce :: Int -> WorkspaceId -> String -> X ()

Lanch the given application n times on the specified workspace. Subsequent attempts to spawn this application will be ignored.

spawnAndDoOnce :: ManageHook -> String -> X ()

Spawn the application once and apply the manage hook. Subsequent attempts to spawn this application will be ignored.
