Hey. I'm trying to configure Xmonad, the window manager. for this purpose, I'm trying to read the *workspaces* variable in the code below from file. As you can see, I do workspaces = readWS where * readWS = do l <- readFile "~/bla" return l* I get an error saying I am mismatching types IO [String] and [String]. But I thought that once one does * l <- readFile "~/bla"*, l is the a string or, in this case, a String list. If I run that line in prelude it seems to be working fine, prints the content of the file "~/bla" on screen (though I'm not sure if as a String or as a list of Strings, i.e. [String]) Can anyone help please? I've been struggling with this for days... 94 main = do 95 xmonad 96 $ defaultConfig { 97 manageHook = manageDocks <+> myManageHook <+> manageHook defaultConfig, 98 layoutHook = avoidStruts $ layoutHook defaultConfig, 99 logHook = dynamicLogWithPP $ conkyPP "", 100 terminal = "gnome-terminal", 101 keys = myKeys, 102 workspaces = readWS, 103 mouseBindings = myMouseBindings, 104 focusedBorderColor = "#008E00", 105 borderWidth = 3 106 --modMask = mod1Mask, --This is to rebind mod key 107 } `additionalKeys`
