This is a convenience module in order to have less import noise. It
re-exports the following:
a) Commonly used modules in full (Data.Foldable, Data.Applicative, and
so on); though only those that play nicely with each other, so that
XMonad.Prelude can be imported unqualified without any problems.
This prevents things like `Prelude.(.)` and `Control.Category.(.)`
fighting with each other.
b) Helper functions that don't necessarily fit in any other module;
e.g., the often used abbreviation `fi = fromIntegral`.
Short-circuiting the search isn't worth the code complexity, so just
search for all windows with the same leader and then pick the first one
using `listToMaybe` and pass that to `doShiftTo`.
Also, rename to `shiftByLeader` because we aren't really shifting to the
leader itself. We just shift to another window that has the same leader.
Will be useful for shiftToLeader.
Use W.shiftWin instead of W.shift as it isn't guaranteed that the window
being managed by the ManageHook is still in focus.
Adds doRectFloat, which floats the new window in the given rectangle; and doCenterFloat, which floats the
new window with its original size, but centered.
The initial patch that extended the EDSL for writing ManageHook rules did not come with a good example on how to use it. This patch ammends that. 'move' is an example of how to write a rule to resolve a Query (Maybe a) into something tangible. 'move'' is an example of how to write a rule isolating window managing code from the rest ofthe mess the EDSL creates.
This patch adds a few types of relationships and operators for managing windows with rules. It provides grouping operators so the X action can access the quantifier that was matched or not matched. It provides a formalism for predicates that work in both grouping and non grouping rules. It could do with some classes, so that there are fewer operators that always do the Right Thing (TM), but the Haskell Type system currently has some problems resolving types. Since I don't know enough about these high level things, it would be hard to create a GHC patch just to make it all work.
