Module : XMonad.Util.XPaste
Author : Jérémy Bobbio
Copyright : (C) 2008
License : BSD3
Maintainer : <gwern0@gmail.com>
Stability : unstable
Portability : unportable
A module for sending key presses to windows. This modules provides generalized
and specialized functions for this task.

module XMonad.Util.XPaste where
import XMonad (io, theRoot, withDisplay, X ())
import Graphics.X11
import Graphics.X11.Xlib.Extras (none, setEventType, setKeyEvent)
import Control.Monad.Reader (asks)
import XMonad.Operations (withFocused)
import Data.Char (isUpper)
import Graphics.X11.Xlib.Misc (stringToKeysym)
import XMonad.Util.XSelection (getSelection)
{- $usage
Import this module into your xmonad.hs as usual:
> import XMonad.Util.XPaste
And use the functions. They all return "X ()", and so are appropriate for use as keybindings.
Example:
> , ((m, xK_d), pasteString "foo bar") ]
Don't expect too much of the functions; they probably don't work on complex
texts.
-}
-- | Paste the current X mouse selection. Note that this uses 'getSelection' from "XMonad.Util.XSelection" and so is heir to its flaws.
pasteSelection :: X ()
pasteSelection = getSelection >>= pasteString
-- | Send a string to the window with current focus. This function correctly handles capitalization.
pasteString :: String -> X ()
pasteString = mapM_ (\x -> if isUpper x then pasteChar shiftMask x else pasteChar 0 x)
{- | Send a character to the current window. This is more low-level.
Remember that you must handle the case of capitalization appropriately. That is, from the window's perspective:
> pasteChar mod2Mask 'F' ~> "f"
You would want to do something like:
> pasteChar shiftMask 'F'
-}
pasteChar :: KeyMask -> Char -> X ()
pasteChar m c = pasteKey m $ stringToKeysym [c]
