How can I have more than 9 workspaces in xmonad?

Question

I can change the names of workspaces, and presumably simply add more by changing this conststant:

myWorkspaces = ["1","2","3⌂","4","5","6","7✉","8☺","9♫"]

If I add something to the array, there will be more workspaces, but how do I keybind them? Mod-1 through Mod-9 are the default but I can't find documentation for how to change that default.

Answer 1

I found the answer buried in this example configuration and together with the key names list, it looks like the following:

Defining a tenth workspace:

myExtraWorkspaces = [(xK_0, "0"),(xK_minus, "tmp"),(xK_equal, "swap")]

myWorkspaces = ["1","2","3⌂","4","5","6","7✉","8☺","9♫"] ++ (map snd myExtraWorkspaces)

Then the key binding looks like this:

myKeys = 
      [ -- ... some more keys ...
      ] ++ [
        ((myModMask, key), (windows $ W.greedyView ws))
        | (key,ws) <- myExtraWorkspaces
      ] ++ [
        ((myModMask .|. shiftMask, key), (windows $ W.shift ws))
        | (key,ws) <- myExtraWorkspaces
      ]

In this example the slash key is used, but any other key from the list above can be used instead.

And finally:

main = do
 xmonad $ config {
           workspaces = myWorkspaces
        } `additionalKeys` (myKeys)
