Here is proof of concept:<br>
<br>
<br>
import XMonad<br>
import XMonad.Hooks.EwmhDesktops<br>
<br>
import System.Directory<br>
import System.FilePath<br>
<br>
<br>
main :: IO ()<br>
main = do<br>
let xcf = ewmh $ def<br>
{ modMask = mod4Mask<br>
, handleExtraArgs = disableKeys<br>
}<br>
xmonad xcf<br>
<br>
disableKeys :: [String] -> XConfig Layout -> IO (XConfig Layout)<br>
disableKeys _ xcf = do<br>
xd <- getXMonadDir<br>
let disableFn = xd </> "disable_keys"<br>
b <- doesFileExist disableFn<br>
if b<br>
then do<br>
trace "Disabling all keys."<br>
removeFile disableFn<br>
return (xcf {keys = \_ -> mempty})<br>
else return xcf<br>
<br>
<br>
To disable all keys create file `~/.xmonad/disable_keys` and then<br>
restart xmonad with `xmonad --restart`. All keys will be disabled<br>
_and_ file deleted (to avoid locking yourself), thus next restart will<br>
restore all keys back.<br>
<br>
As far as i understand, xmonad grabs keys in `X.Main.launch` before<br>
entering main loop. Thus, the one way to change key grab is to restart<br>
xmonad. I need to modify `XConfig` before calling X.Main.launch`, and<br>
this may be done by `handleExtraArgs` (called in `launch'` in<br>
`X.Main.xmonad`). Unfortunately, it seems, that xmonad does not allow<br>
to pass extra cmd arguments during restart (`X.Operations.restart`<br>
always starts xmonad with name `xmonad` and no arguments). Also, i<br>
can't use extensible state in `handleExtraArgs`, because it runs in<br>
`IO` (`X` context is not yet built at that time). Thus, to pass<br>
something to it, i may use either file or (probably) `--replace`. The<br>
above version uses file. And i have no luck with `--replace`: it<br>
seems, `xmonad` can't replace itself?..<br>
