This patch starts Emacs as a foreground daemon (so it can accurately be
killed) and terminates it by sending a signal (because
'server-force-delete' stops the local server, not the named server).
* exwm.el (exwm--server-timeout): The time to politely wait for the
subordinate server to exit before killing it.
(exwm--server-stop): Send SIGTERM to the subordinate process instead of
using 'server-force-delete'.
(exwm--server-eval-at): Prevent Emacs from forking so we can manage it
as a subprocess.
* exwm-workspace.el (exwm-workspace--remove-frame-as-workspace):
Add optional argument quit.
* exwm-background.el (exwm-background--exit):
* exwm-input.el (exwm-input--exit):
* exwm-manage.el (exwm-manage--unmanage-window):
* exwm-systemtray.el (exwm-systemtray--exit):
* exwm-workspace.el (exwm-workspace--exit-minibuffer-frame)
(exwm-workspace--exit):
* exwm-xim.el (exwm-xim--exit): Observe connection status when
deinitializing in order to support deinitializing when the
connection breaks.
* exwm.el (exwm--on-ClientMessage): Take care of focusing
workspace frames when a _NET_ACTIVE_WINDOW message is received for
a workspace frame. This is responsibility of the window manager
when it advertises _NET_ACTIVE_WINDOW support, which we do.
Emacs versions before 29 took care of setting the input focus to
the frame.
Thanks-to: Po Lu for the work on Emacs and assistance with this
issue.
* 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-echo-area-clear)
(exwm-workspace--on-delete-frame): Use it.
* exwm-workspace.el (exwm-workspace--client-p-hash-table): Remove
variable.
(exwm-workspace--client-p): Remove function.
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--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-layout.el (exwm-layout--set-ewmh-state): New function for
setting _NET_WM_STATE (according to local state).
* exwm.el (exwm--init-icccm-ewmh): Declare the support for this atom.
* exwm.el (exwm--on-ClientMessage): Calling `kill-buffer' directly
from an event context won't work since the DestroyNotify event for a
WM_DELETE_WINDOW request won't be handled until the current event
context terminates.
* exwm-manage.el (exwm-manage--kill-buffer-query-function): Avoid
potential side effects with MapWindow.
* 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.el (exwm-replace): New user option for specifying whether to
replace existing WM.
(exwm-init): Use it.
(exwm--wmsn-acquire, exwm-init): Do not print warning message when
user gives up replacing.
* exwm-core.el (exwm--wmsn-replace): Remove dead code.
