[xmonad] [SOLVED] Re: Complex hotkeys definition

-- Awesome! , ("M-2", spawn "something" *> windows (W.view "2")) did it!

...

race condition:

Thanks for the hint; maybe I can use that later. Anyway, in fact I don't want to spawn "konsole" but "xdotool" with a key combo (for some KDE5 action) – and so far it's working great! ^^ Am 17.01.22 um 21:10 schrieb Brandon Allbery:

You have two problems. The first is that `$` extends as far as possible, so `spawn` ends up being grouped with `W.view` instead of with `windows`; fix this by using explicit parentheses instead of `$`, that is `windows (W.view "2")`. The second is that the correct operator to use is either `*>` or `>>`.

Although you will then discover a third problem, which is a race condition because `spawn` is asynchronous (Linux is not Windows), meaning sometimes the new window will open on the previously active workspace. You may want to use https://hackage.haskell.org/package/xmonad-contrib-0.17.0/docs/XMonad-Action... instead (don't forget to add https://hackage.haskell.org/package/xmonad-contrib-0.17.0/docs/XMonad-Action... to the `manageHook` or it won't work).

Dear all,

yet I failed properly occasionally extending "myHotkeys" commands with additional arguments, e.g. like also spawning something when switching workspaces.

Say, the default is something like:

myHotkeys = [ ... , ("M-2", windows $ W.view "2") ... ]

for hitting for changing to workspace "2".

But what if I wanted to additionally execute some extra command or app – such as launching "konsole" (just for testing; I am going to do something else)?

Simply editing and adding stuff link

, ("M-2", windows $ W.view "2" $ spawn "konsole") or , ("M-2", windows $ W.view "2" . spawn "konsole") or , ("M-2", windows $ W.view "2" || spawn "konsole") or , ("M-2", windows $ W.view "2" <+> spawn "konsole")

doesn't work, due to compilation errors.

I am no programmer and haven't yet found the right operators or order; or am I missing brackets? And I don't get the error logs in detail really.

Thanks in advance! _______________________________________________ xmonad mailing list xmonad@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/xmonad
