To keep the behaviour of the old code, we want to fall back to the
unfocused format here, not the identity.

`WindowScreen` is a type synonym for the specialized `Screen` type, that
results from the `WindowSet` definition in XMonad.Core. Having this type
defined and exported in a central module saves extension developers from
trying to reconstruct it, whenever the general `Screen i l a sid sd` is
not suitable.
Note: this should be moved to `XMonad.Core` in the next core release.
This works like logTitles, but gets an explicit screen to log the window
titles on. This may be useful when having status bars for each screen
that show all windows on their respective visible workspaces.
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`.
- `logWhenActive` to have loggers active only when a certain screen is
active.
- `logTitleOnScreen`, `logCurrentOnScreen` and `logLayoutOnScreen` as
screen-specific variants of `logTitle`, `logCurrent`, `logLayout`
- `logConst` to log a constant `String`
- `logMaybe` and `.|` to combine loggers.
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.
The base that comes with ghc-7.6.1 no longer includes Prelude.catch;
so these modules were changed so that there is no warning for
import Prelude hiding (catch)
At the same time these changes should be compatible with older GHCs,
since the catch being has never been the one in the Prelude.
* true error: more modules export foldl/foldl'/foldr, so explicitly use the Data.Foldable one
* -Werror error: transition from Control.OldException to Control.Exception, assuming everything was IOException
Rework of the Logger portions of patches originally from seanmce33@gmail.com
to apply without conflicts, plus several formatting utilities for use with
X (Maybe String) aka Loggers.
Improvements to DynamicLog include:
* Greatly expanded and improved documentation and examples
* remove seemingly useless makeSimpleDzenConfig function
* factor out xmobarPP
* add new ppExtras field to PP record, for specifying 'extra'
loggers which can supply information other than window title,
layout, and workspace status to a status bar (for example, time and date,
battery status, mail status, etc.)
The new XMonad.Util.Loggers module provides some example loggers that
can be used in the new ppExtras field of the PP record. Create your own,
add them to this module, go crazy! =)
