;;; Commentary:
;; Overview
;; --------
;; EXWM (Emacs X Window Manager) is a full-featured tiling X window manager
;; for Emacs built on top of [XELB](https://github.com/ch11ng/xelb).
;; It features:
;; + Fully keyboard-driven operations
;; + Hybrid layout modes (tiling & stacking)
;; + Dynamic workspace support
;; + ICCCM/EWMH compliance
;; + (Optional) RandR (multi-monitor) support
2016-08-15 16:59:48 +02:00
;; + (Optional) Built-in system tray
2015-07-17 13:16:08 +02:00
;; Installation & configuration
;; ----------------------------
;; Here are the minimal steps to get EXWM working:
;; 1. Install XELB and EXWM, and make sure they are in `load-path'.
;; 2. In '~/.emacs', add following lines (please modify accordingly):
2015-07-17 13:16:08 +02:00
;;
;; (require 'exwm)
;; (require 'exwm-config)
;; (exwm-config-example)
2015-07-17 13:16:08 +02:00
;;
;; 3. Link or copy the file 'xinitrc' to '~/.xinitrc'.
;; 4. Launch EXWM in a console (e.g. tty1) with
2015-07-17 13:16:08 +02:00
;;
;; xinit -- vt01
2015-07-17 13:16:08 +02:00
;;
;; You should additionally hide the menu-bar, tool-bar, etc to increase the
;; usable space. Please check the wiki (https://github.com/ch11ng/exwm/wiki)
;; for more detailed instructions on installation, configuration, usage, etc.

Rework the X windows hierarchy model This commit add workspace and X window containers support to avoid using Emacs frames as the parents of X windows. This should make it easier to set input focus. * exwm-core.el (exwm--container, exwm--floating-frame-position): New file local variables. (exwm--floating-frame-geometry): Removed file local variable. * exwm-floating.el (exwm-floating--set-floating) (exwm-floating--unset-floating, exwm-floating--do-moveresize) (exwm-floating-move): Use container. (exwm-floating--fit-frame-to-window): No longer adjust stacking order. (exwm-floating--fit-frame-to-window): The first member is changed to buffer. (exwm-floating--start-moveresize): Use container. Correctly set input focus. * exwm-input.el (exwm-input--redirected, exwm-input--on-focus-in): Removed. (exwm-input--on-buffer-list-update): Remove the restriction on floating frames which is no longer valid. (exwm-input--update-focus): Adjust stacking order. (exwm-input--on-minibuffer-setup): New function for setting focus on the Emacs frame when entering minibuffer. (exwm-input--on-KeyPress-line-mode): No longer compensate FocusOut event. (exwm-input--grab-keyboard, exwm-input--release-keyboard): Local keys are now grabbed on the X window container. (exwm-input--init): Add `exwm-input--on-minibuffer-setup' to `minibuffer-setup-hook'. * exwm-layout.el (exwm-layout--resize-container): New function to resize/reposition both the X window and its container. (exwm-layout--show, exwm-layout--hide): Use container. (exwm-layout-set-fullscreen): Use container. No longer save width and height. (exwm-layout-unset-fullscreen, exwm-layout--set-frame-fullscreen): Use container. (exwm-layout--refresh): Update a frame parameter. Remove dead code. * exwm-manage.el (exwm-manage--manage-window): Reparent unmanaged X windows to the workspace. Create X window container as the parent of the X window. (exwm-manage--unmanage-window): Unmap/destroy container when appropriate. Use the position of container. (exwm-manage--unmanage-window): Destroy the container. * exwm-randr.el (exwm-randr--refresh): Resize workspace using container. * exwm-workspace.el (exwm-workspace-switch): Raise workspace. Correctly set input focus. (exwm-workspace--on-focus-in): Removed. (exwm-workspace-move-window): Reparent to workspace container. (exwm-workspace--init): Create workspace frames as visible. Create workspace containers. Remove exwm-workspace--on-focus-in from focus-in-hook. Update _NET_VIRTUAL_ROOTS. * exwm.el (exwm-init): No longer disable hourglass window. Initialize workspace module before input. * exwm-core.el (exwm--debug): New macro for setting debug forms. * exwm-floating.el (exwm-floating--set-floating): No longer do `exwm--lock' and `exwm--unlock' since `make-frame' is already adviced to take care of everything. Correctly set input focus to the newly created floating X window. * exwm-core.el (exwm--floating-edges): Removed file local variable. * exwm-floating.el (exwm-floating--set-floating) (exwm-floating--unset-floating): * exwm-layout.el (exwm-layout--show, exwm-layout-enlarge-window): * exwm-manage.el (exwm-manage--on-ConfigureRequest): No longer use floating geometry. * exwm-input.el (exwm-input--update-global-prefix-keys): Grab global keys on workspaces containers instead of the root window (or input focus would transfer to the workspace containing the pointer when the grab is active). * exwm-workspace.el (exwm-workspace-switch): No longer move mouse.

Make X windows container-less ; This is an attempt to make (managed) X windows container-less, i.e. direct children of the root window. This is mainly to make EXWM compatible with third-party compositors. Other issues like wrong absolute position should also get resolved by the way. The workspace containers ("virtual roots") are also removed. However Emacs frames are still wrapped in containers to avoid unexpected stack reordering. * exwm-cm.el: Make this module obsolete as EXWM supports third-party compositors now. * exwm-core.el (exwm--container): * exwm-floating.el (exwm-floating--set-floating) (exwm-floating--unset-floating, exwm-floating-hide) (exwm-floating--start-moveresize, exwm-floating--stop-moveresize) (exwm-floating--do-moveresize, exwm-floating-move): * exwm-input.el (exwm-input--update-focus): * exwm-layout.el (exwm-layout--show, exwm-layout--hide) (exwm-layout-set-fullscreen, exwm-layout-unset-fullscreen): * exwm-manage.el (exwm-manage--manage-window, exwm-manage--unmanage-window) (exwm-manage--kill-buffer-query-function, exwm-manage--kill-client): * exwm-workspace.el (exwm-workspace--set-fullscreen, exwm-workspace-switch) (exwm-workspace-move-window, exwm-workspace--add-frame-as-workspace) (exwm-workspace--remove-frame-as-workspace): Make adaptions for container-less X windows. * exwm-workspace.el (exwm-workspace--update-ewmh-props): * exwm.el (exwm--init-icccm-ewmh, exwm--exit-icccm-ewmh): No longer use virtual roots. * exwm-input.el (exwm-input--on-workspace-list-change) (exwm-input--update-global-prefix-keys, exwm-input--init, exwm-input--exit): From now on global key bindings are grabbed on the root window so it's no long required to re-grab them each time the workspace list changes. As a result `exwm-input--on-workspace-list-change' and its corresponding references are discarded. It remains to be seen if this change will raise input focus issues. * exwm-manage.el (exwm-manage--manage-window): Explicitly set the workspace for newly managed X windows. * exwm-floating.el (exwm-floating--set-floating): Avoid implicit reference to the current workspace. * exwm-core.el (exwm--set-geometry): New function for setting the geometry of an X window. * exwm-layout.el (exwm-layout--resize-container): Replaced by `exwm-layout--resize-container'. * exwm-core.el (exwm--guide-window): New global variable recording the guide X window. * exwm.el (exwm--init-icccm-ewmh): Set it. * exwm-input.el (exwm-input--post-init): New function containing staffs for initialization but should better get called after the event loop starts. * exwm.el (exwm-init): Use it.
