For the case of vertical columns of workareas, top and bottom struts
should only apply to workareas containing the respective edge of the
strut offset.
To simplify, imagine three monitors arranged vertically and one
workarea per display:
+-------+
| 1 | 2000x1000 px
+-------+
| 2 | 2000x1000 px
+-------+
| 3 | 2000x1000 px
+-------+
In sexp form: ((0 0 2000 1000) (0 1000 2000 1000) (0 2000 2000 1000))
where each element represents a workarea as x, y, width, height
And example struts of the form (offset-type offset (x-start x-end))
a.) (top 42 (0 2000))
b.) (top 1042 (0 2000))
c.) (top 2042 (0 2000))
d.) (bottom 42 (0 2000))
e.) (bottom 1042 (0 2000))
f.) (bottom 2042 (0 2000))
Workareas adjusted for struts before this change:
a.) ((0 42 2000 958) (0 1000 2000 1000) (0 2000 2000 1000))
b.) ((0 1042 2000 -42) (0 1042 2000 958) (0 2000 2000 1000))
c.) ((0 2042 2000 -1042) (0 2042 2000 -42) (0 2042 2000 958))
d.) ((0 0 2000 1000) (0 1000 2000 1000) (0 2000 2000 902))
e.) ((0 0 2000 1000) (0 1000 2000 902) (0 2000 2000 -98))
f.) ((0 0 2000 902) (0 1000 2000 -98) (0 2000 2000 -1098))
Note that a. and d. are sensible, while b., c., e., and f. are quite
user unfriendly.
After this change, the same adjusted workareas are:
a.) no change
b.) ((0 0 2000 1000) (0 1042 2000 958) (0 2000 2000 1000))
c.) ((0 0 2000 1000) (0 1000 2000 1000) (0 2042 2000 958))
d.) no change
e.) ((0 0 2000 1000) (0 1000 2000 902) (0 2000 2000 1000))
f.) ((0 0 2000 902) (0 1000 2000 1000) (0 2000 2000 1000))
The intent is to allow dock type windows such as typical status bars
to occupy space in a workarea on any of a set of vertically arranged
displays without occluding the other workareas due to the limitations
of the X spec regarding strut offsets.
Note that this behaviour conflicts with EWMH 1.3:
> Struts MUST be specified in root window coordinates, that is,
they are *not* relative to the edges of any view port or Xinerama
monitor.

* exwm-xim.el (exwm-xim--exit): Observe connection status when
deinitializing in order to support deinitializing when the
connection breaks.
* exwm-core.el (exwm--get-visual-depth-colormap): New function.
* exwm-workspace.el (exwm-workspace--add-frame-as-workspace): Use
Emacs' frame's visual, depth and colormap. Reset all attributes
that refer (also by default) to the parent window (the root
window), as it might have a different visual, depth or colormap.
Special-thanks-to: Elijah Malaby <qwe12345678910@gmail.com> for figuring out the
changes needed to suport 32-bit visuals and proposing the initial
version of this improvement.
* exwm-core.el (exwm--terminal-p): Add function.
* exwm.el (exwm--confirm-kill-terminal): Use it.
* exwm-input.el (exwm-input--on-buffer-list-update): Use it.
(exwm-input--on-minibuffer-setup)
(exwm-input--on-minibuffer-exit): Use it.
(exwm-input--on-minibuffer-exit): Use the minibuffer's selected
window's frame or selected frame instead of current workspace.
(exwm-input--on-echo-area-dirty): Removed test, as it's checked in
`exwm-input--on-minibuffer-setup'.
* exwm-layout.el (exwm-layout--on-minibuffer-setup)
(exwm-layout--on-echo-area-change): Use it.
(exwm-layout--on-echo-area-change): Refresh layout the
frame of selected window's minibuffer if it's an EXWM frame.
* exwm-workspace.el (exwm-workspace--update-minibuffer-height)
(exwm-workspace--on-minibuffer-setup)
(exwm-workspace--on-minibuffer-exit)
(exwm-workspace--on-echo-area-dirty)

(exwm-workspace--on-delete-frame): Use it.
* exwm-workspace.el (exwm-workspace--client-p-hash-table): Remove
variable.
(exwm-workspace--client-p): Remove function.
EXWM removed the `client' frame parameter from workspace frames,
perhaps in order to lead Emacs to ask for confirmation before
quitting. This change leaves the `client' frame parameter in
place. Emacs no longer asks for confirmation when killing the
emacsclient session. A followup commit will correct this.
* exwm-workspace.el (exwm-workspace--add-frame-as-workspace)
(exwm-workspace--init-minibuffer-frame, exwm-workspace--init)
(exwm-workspace--exit, exwm-workspace--post-init): Remove special
handling for `client' frames. They become workspaces just like
any other frame.
Check whether frames are alive upon teardown, as it might not be
the case when the terminal is killed as
`delete-terminal-functions' might be invoked after the terminal is
deleted.
* exwm-core.el (exwm--terminal): New variable holding the terminal
EXWM runs under.
(exwm-init, exwm-exit): Set and unset it.
* exwm.el (exwm--on-delete-terminal): New function for exiting
EXWM when the terminal is deleted.
(exwm-init): Use it.
* exwm.el (exwm--confirm-kill-terminal, exwm-init): Ask for
confirmation before deleting terminal.
* exwm-workspace.el (exwm-workspace--fullscreen-workspace): New
function. Ensure the frame is alive.
(exwm-workspace--add-frame-as-workspace): Use it.
(exwm-workspace--exit-minibuffer-frame): Cancel
`exwm-workspace--display-echo-area-timer'.
(exwm-workspace--exit-minibuffer-frame): Ensure the minibuffer
frame is alive.
(exwm-workspace--exit): Ignore dead workspace frames.
* exwm-workspace.el (exwm-workspace--get-next-workspace): Return
nil when there's only one frame.
(exwm-workspace--on-delete-frame)
(exwm-workspace--remove-frame-as-workspace): Create a workspace
when removing the last one, for X windows to be moved to.
* exwm-workspace.el (exwm-workspace--prompt-delete)
(exwm-workspace--set-desktop): Stop explicitly moving X windows to
other workspace; dealt with by
`exwm-workspace--remove-frame-as-workspace'.
(exwm-workspace--get-remove-frame-next-workspace): Remove
function. Refactored into `exwm-workspace--get-next-workspace'
and `exwm-workspace--remove-frame-as-workspace'.
(exwm-workspace--get-next-workspace): Add function.
(exwm-workspace--remove-frame-as-workspace): Move X windows to
next workspace.
* exwm-workspace.el (exwm--client-p-hash-table): New variable.
(exwm-workspace--client-p): Use `exwm--client-p-hash-table' to
store which workspace frames are client frames instead of
frequently invoking `frame-parameter'.
* exwm-workspace.el (exwm-workspace-switch): Stop aborting
recursive edit upon switching workspaces. Users should handle it
just like in regular Emacs (possibly customizing
`enable-recursive-minibuffers').
* exwm-workspace.el (exwm-workspace-switch): Abort recursive edit
before switching to other workspace. This avoids the usual
`set-window-configuration' calls (e.g., by `eval-expression') to
switch *us back to the previous workspace.
* exwm-workspace.el (exwm-workspace--update-offsets): Explicitly
request the geometry of the container for the first workspace as it
may not align with the top of the root X window.
* exwm-workspace.el (exwm-workspace--frame-y-offset)
exwm-workspace--window-y-offset, exwm-workspace--update-offsets): New
variables & function for the calculation of Emacs frame offsets, as
`frame-geometry' is not available in Emacs 24.
* exwm-floating.el (exwm-floating--set-floating)
(exwm-floating--do-moveresize):
* exwm-layout.el (exwm-layout--show):
* exwm-systemtray.el (exwm-systemtray--on-workspace-switch)
(exwm-systemtray--on-randr-refresh, exwm-systemtray--init): Use them.
* exwm-systemtray.el (exwm-systemtray--refresh-all): Renamed from
`exwm-systemtray--on-randr-refresh'.
(exwm-systemtray--init, exwm-systemtray--exit): Use it.
* exwm-floating.el (exwm-floating--stop-moveresize): Send a
ConfigureNotify event to floating frame to update its position (seems
required by Emacs 24).
* exwm-floating.el (exwm-floating-border-color)
(exwm-floating-border-width): Make changes take effect w/o restart.
(exwm-floating--init-border): Refactored out from
`exwm-floating--init'.
* exwm-workspace.el (exwm-workspace-minibuffer-position): Clarify
a restart is required.
* exwm-workspace.el (exwm-workspace--original-handle-focus-in)
(exwm-workspace--original-handle-focus-out): Store the original
`handle-focus-{in,out}'.
(exwm-workspace-switch): Now that `handle-focus-{in,out}' has been
updated to call other stuffs like `after-focus-change-function', we
can no longer run `focus-{in,out}-hook' only.
* exwm-workspace.el (exwm-workspace--get-remove-frame-next-workspace):
New function automatically moves X window elsewhere before removing a
workspace; also returns the destination workspace.
(exwm-workspace--prompt-delete, exwm-workspace-delete)
(exwm-workspace--remove-frame-as-workspace): Use it.
* exwm.el (exwm--on-ClientMessage): Use it.
* exwm-workspace.el (exwm-workspace--switch-map)
(exwm-workspace--init): Avoid initializing the keymap when loading.
(exwm-workspace--init-switch-map): Initialize
`exwm-workspace--switch-map' and also add extra keybindings when
`exwm-workspace-index-map' has been customized.
* exwm-randr.el (exwm-randr-workspace-monitor-plist): New user option
for specifying which monitor each workspace should be displayed on.
(exwm-randr-workspace-monitor-plist): Made obsolete.
(exwm-randr--get-monitors): New function for fetching active monitors.
(exwm-randr--refresh): Adapted to use monitor.
(exwm-randr--init): Now requires RandR 1.5.
* exwm-randr.el:
* exwm-workspace.el: Rename `output' to `monitor'.
* exwm-input.el (exwm-input--event-hook): New variable.
(exwm-input--on-ButtonPress, exwm-input--on-KeyPress): Run
`exwm-input--event-hook'.

Hide minibuffer upon noticing an event.
* exwm-workspace.el (exwm-workspace--echo-area-maybe-clear): New
function that postpones hiding the minibuffer when it's displaying
a message.
(exwm-workspace--on-echo-area-dirty): Use it.
* exwm-workspace.el (exwm-workspace-switch): On startup EXWM switches
to workspace 0 by force so the rest code can not assume the frames
before and after a switch different.
