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`.
Starting with 5240116f3cdf169e3aa226d9f8206a5f5b99c867 we only support
GHC versions 8.4.4 and up (more precisely, the GHC version associated
with stackage lts-12 and up). The imports in question are now in
Prelude and need not be imported explicitly.
As it now consists of a startup hook, a manage hook, an event hook and
a layout modifier, and behaves erratically when any one component is not
included in a user's config (which happens to be the case for all
configs from xmonad-contrib 0.12 since the startup hook is a new
inclusion), it's probably wise to have a single function that adds
all the hooks to the config instead.
NB: This will need a release notes entry anyway!
