1 patch for repository http://code.haskell.org/XMonadContrib: Fri May 4 10:38:29 EST 2012 gopsychonauts@gmail.com * Converted UrgencyHooks to simple Window -> X () functions Previously, UrgencyHooks were members of the typeclass UrgencyHook, and had to implement Read and Show instances. This was for historical reasons, as originally the UrgencyHook was stored as a layout modifier. Changes in the module's implementation---it now uses handleEventHook and logHook instead---mean that those constraints are no longer needed. Thus, changing the UrgencyHook to a simpler single type is possible. This makes writing new UrgencyHooks simpler, as now they're just functions and don't require a whole new typeclass instance. It also allows for useful behaviour such as UrgencyHook being a Monoid: this increases cohesion in an XConfig definition since multiple UrgencyHooks may now be combined with <+>, just as manageHook and logHook may be. Regrettably, this does break compatibility with any previously-defined custom urgency hooks, since the UrgencyHook typeclass no longer exists.
