X windows in line-mode receive KeyPress events faked with SendEvent requests
previously. This causes many problems including:
* Some applications (e.g. xterm) ignore synthetic events completely
* KeyPress and KeyRelease evnets arrive disorderly
This commit makes EXWM exploiting AllowEvents requests (in ReplayKeyboard mode)
to forward KeyPress events to X windows instead.
* exwm-layout.el (exwm-layout-unset-fullscreen)
(exwm-layout-set-fullscreen): Use `user-error' rather than
`cl-assert'.
* exwm-input.el (exwm-input--set-focus): Silently accept unknown
ids. (exwm-input--grab-keyboard) (exwm-input--release-keyboard):
Silently ignore calls for windows that have no buffer.
* exwm-manage.el (exwm-manage--kill-client): Don't throw error
when trying to kill a vanished window.
* RandR module is now made optional; users can enable it with
`exwm-randr-enable`.
* Correct the calculation of sizes/coordinates at various places.
* Input focus is now tracked with (Emacs) window instead of buffer since the
latter can be ambiguous in multi-screen settings.
This commit should fix most input focus bugs (especially those related to
floating windows). The actual settings of input focus are delayed to exclude
redundant event. Dead code since this commit is removed.
This commit also fixes a bug for non-floating windows converted form floating
state. The workaround for `ido-mode` is also improved to properly handle
`exwm-mode` buffers.
This commit makes a floating window centered to its leading window if it has
a valid WM_TRANSIENT_FOR property set. Other it's placed at the center of the
screen.
For some reason, `MappingNotify` events are generated quite frequently and
greatly impact the performance. This commit disables the complete refresh of
keyboard mapping.
Remove `exwm--with-current-id`, which was introduced to as a wrapper to
`with-current-buffer` to do extra checks. Note that in functions run as hooks,
the validation of window ID is still required as they are not synchronized with
events.
`emacsclient` started with `-c` or `-t` argument create a new frame that shall
not be used to manage X windows.
Also fix some related input focus issues (with some remaining unfixed).
Close#17.
* Fix `exwm-reset`
* Make input mode buffer local
* Allow window to stay in `char-mode` while setting input focus to other window
or switching to other workspace
* Prevent marking the end of a key sequence with a single `C-u'.
* Enable `C-u' prefix for key simulation since it's not possible for users to
define simulation keys starting with `C-u'.
* Make Emacs idle only after the visual parts are updated to prevent from
disturbing users.
* Should use '?\s' instead of '? '.
