Using `message' to log debugging information is cumbersome, as the output
appears constantly in the minibuffer, obscuring prompts and other information.
In the case of long messages, it might resize the minibuffer, which causes EXWM
to perform additional actions due to the log output.
This change reimplements EXWM debug logging using a separate
buffer (*EXWM-DEBUG*). Basic functionality, like scrolling when point is at the
end of the buffer is maintained.
* exwm-core.el (exwm--log): Use `exwm-debug--message' instead of
`message'. Prefix all messages with the name of the function.
Make FORMAT-STRING argument optional.
* exwm-debug.el: New file.
(exwm-debug-buffer): New variable holding the buffer where debug
messages are output to.
(exwm-debug--message): New function printing a message to
`exwm-debug-buffer'.
(exwm-debug--backtrace): New function printing a backtrace.
* exwm-manage.el (exwm-manage--unmanage-window): Set the Emacs window
of an full screen X window as non-dedicated before killing its buffer
so as not to cause other side effects.
* exwm-manage.el (exwm-manage--on-ConfigureRequest): There's a problem
in shrinking Emacs frames with `set-frame-width' and
`set-frame-height'. Use `exwm--set-geometry' instead.
; A change has been made in Xorg server 1.20 that replaying a key
; event with keyboard grabbed would generate extra focus change and
; enter/leave events. This basically breaks line-mode for apps like
; Firefox. This commit reimplements the grab & replay functionality
; with XI2 and XTEST.
