{- $usage
|
|
|
|
Import this module into your xmonad.hs as usual:
|
|
|
|
> import XMonad.Util.Paste
|
|
|
|
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 which is currently focused. This function correctly
|
|
-- handles capitalization.
|
|
pasteString :: String -> X ()
|
|
pasteString = mapM_ (\x -> if isUpper x then pasteChar shiftMask x else pasteChar noModMask 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'
|
|
|
|
Note that this function makes use of 'stringToKeysym', and so will probably
|
|
have trouble with any 'Char' outside ASCII.
