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`.
This enables adding the Typeable constraint to LayoutClass itself
(https://github.com/xmonad/xmonad/pull/242) which in turn enables
querying the current layout state. That might be useful to e.g. show the
current X.L.WorkspaceDir in xmobar.
This is a preparation commit that fixes the compile failures that would
result in merging that change to xmonad. For this to be generally useful
we first need to merge (and ideally also release) that xmonad change,
and then we'll need some documentation and perhaps a type class to help
find the right LayoutModifier in the tree of ModifiedLayouts and
Choices. That will come later.
X.L.LayoutBuilderP is nearly identical to X.L.LayoutBuilder. Originally
I wanted to add the ability to dynamically resize the layout boxes so it
make a lot of sense to join these two modules together so I wouldn't
have to do it in both. Even though I never got around to that I still
think it's a good idea to merge these two modules into one.
I believe I was able to merge these without creating any
backward-compatibility issues. I've been sitting on these changes since
2015 and they work for me without having to change older parts of my
config (relating to X.L.LayoutBuilder).
If anyone wants to work on dynamically resizing layout boxes the issue I
created for it is #36.
Despite myLayouts currently being more popular in examples, make
them all myLayout as in man/xmonad.hs to avoid mixing them in the
same module as was done a few places, leading to confusion for some users.
