Description

Evaluate haskell expressions at runtime in the running xmonad instance.

Synopsis

evalExpression :: EvalConfig -> String -> X ()

evalExpressionWithReturn :: EvalConfig -> String -> X String

data EvalConfig = EvalConfig {

handleError :: InterpreterError -> X String

imports :: [(ModuleName, Maybe String)]

modules :: [String]

}

defaultEvalConfig :: EvalConfig

Usage

This module provides functions to evaluate haskell expressions at runtime To use it, bind a key to evalExpression, for example in combination with a prompt:

 import XMonad
 import XMonad.Actions.Eval
 import XMonad.Prompt.Input
 ..
   , ((modMask,xK_t), inputPrompt defaultXPConfig "Eval" >>= flip whenJust (evalExpression defaultEvalConfig))

For detailed instructions on editing your key bindings, see XMonad.Doc.Extending.
