For many (10+) years, we had a cascade of ugly workarounds:
* X.U.Run.spawnPipe returned a binary handle, so the String passed to
it must have been encoded by C.B.UTF8.String.encodeString
* X.H.DynamicLog.dynamicLogString therefore returned such an encoded
String, so one could use it directly in a hPutStrLn, but literal
Strings wouldn't work
* xmonadPropLog' also expected an encoded String to make it easier to
use together with dynamicLogString, again breaking usage with String
literals and other normal unicode Strings
Then in 1d0eaddc25 Sibi fixed spawnPipe to return a handle usable with
normal Strings, which then obviously broke the entire cascade. But,
instead of using the opportunity to remove all the ugly workarounds, he
decided to add some more on top, so now spawnPipe with dynamicLogString
outputs doubly encoded UTF-8 and xmobar has a hack to strip this double
encoding (https://github.com/jaor/xmobar/pull/482), which only works
when XFT is in use and breaks on some long unicode codepoints. :-(
There is a better way: make everything just use normal Strings and only
encode when it goes out the wire. This means dynamicLogString can be
freely mixed with String literals, manual uses of xmonadPropLog' don't
need encodeString, and everything just works nicely.
This obviously breaks configs that used some of these pieces in
isolation (like mine), but that's a small price to pay. After all, right
now all users of spawnPipe/dynamicLogString are getting doubly encoded
UTF-8 which might or might not work in xmobar and probably breaks
horribly everywhere else, so this fix should be a clear improvement. :-)

This makes it easier to see the differences between these functions,
makes it less likely someone will change one and not the others, etc.
More importantly, the documentation doesn't contain circular references
any more. :-)
Also, let's just use hSetEncoding. The concern of this being stateful
and theoretically having something written in the wrong encoding is
pointless: nobody has the handle until we return it from `spawnPipe'`.
(This also means that spawnPipeWithNoEncoding is now a text handle that
possibly does newline translation, just with char8 encoding. There
should be no difference in practice.)

This breaks putting <fn> tags and icons into workspace names, which some
people might like. Those few who generate workspace names dynamically
from window titles may (and should) escape it themselves.
* New logout options
Factor out Mate logout action and add a shutdown action which the user can bind additionally or in its place.
* Add documentation
* Update CHANGES.md
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.
When focus changes¹ on an inactive workspace (not `current`, but
`visible`), TrackFloating and UseTransientFor would think they should
use the remembered focus point as they look at the wrong (`current`)
workspace instead of the workspace they're supposed to layout, and so
focus seems to be out of their set of windows, when actually it is not.
Fix this by looking at the correct workspace.
¹) This isn't entirely straightforward, as there are normally no
keybindings or StackSet operations for this, but it's perfectly legal
to `W.view` the inactive workspace, change focus, and `W.view` back
in a single `windows` action.
If a manually crafted ClientMessageEvent with invalid (nonexistent)
ev_window is sent to xmonad (by sending it to the root window), the
nonexistent window is added to Urgents and stays there forever.
This can also happen when a window in Urgents disappears while xmonad is
restarting, in which case xmonad never sees the DestroyWindowEvent and
never gets to remove the window from Urgents.
As both of these are fairly unlikely, only do the cleanup in
startupHook to not waste cycles.
The EWMH support added in 7e9c986217 only added handling of
_NET_WM_STATE_DEMANDS_ATTENTION to handleEvent and cleanupUrgents, but
manual urgency clearing via clearUrgents or automatic urgency clearing
via filterUrgencyHook was left without EWMH support. This commit adds
the missing pieces.
Fixes: 7e9c986217 ("Add EWMH DEMANDS_ATTENTION support to UrgencyHook.")
Atoms are at most 32-bit even on 64-bit platforms, per the X protocol,
despite them being stored in a CLong. Even if they weren't (and they
are, see /usr/include/X11/Xproto.h and
https://stackoverflow.com/a/23265984/3407728), xmonadctl isn't unpacking
the CLong into multiple data items.
Stop pretending it has anything to do with time, it's zero, and it's not
being read anywhere, we're passing the parameter only because
setClientMessageEvent needs one. We should switch to
setClientMessageEvent' and pass no data, but that would move the X11
dependency lower bound.
- StatusBarConfig serves as an abstraction over status bars. This
enables users to customize their status bars without having to do
the plumbing themselves.
- Multiple status bars can be used directly thanks to the
StatusBarConfig, which provides a way to compose status bars
