== Coding guidelines for contributing to == xmonad and the xmonad contributed extensions * Comment every top level function (particularly exported funtions), and provide a type signature; use Haddock syntax in the comments. * Follow the coding style of the other modules. * Code should be compilable with -Wall -Werror. There should be no warnings. * Partial functions should be avoided: the window manager should not crash, so do not call `error` or `undefined` * Tabs are illegal. Use 4 spaces for indenting. * Any pure function added to the core should have QuickCheck properties precisely defining its behaviour. * New modules should identify the author, and be submitted under the same license as xmonad (BSD3 license or freer).
