It talks with X windows through the XIM protocol. The XIM +;; protocol is quite flexible by itself, stating that an implementation can +;; create network connections of various types as well as make use of an +;; existing X connection for communication, and that an IM server may +;; support multiple transport versions, various input styles and several +;; event flow modals, etc. Here we only make choices that are most popular +;; among other IM servers and more importantly, practical for Emacs to act +;; as an IM server: +;; +;; + Packets are transported on top of an X connection like most IMEs. +;; + Only transport version 0.0 (i.e. only-CM & Property-with-CM) is +;; supported (same as "IM Server Developers Kit", adopted by most IMEs). +;; + Only support static event flow, on-demand-synchronous method. +;; + Only "root-window" input style is supported. + +;; To use this module, enable it as follows: +;; +;; (exwm-xim-mode 1) +;; +;; A keybinding for `toggle-input-method' is probably required to turn on & +;; off an input method (default to `default-input-method'). It's bound to +;; 'C-\' by default and can be made reachable when working with X windows: +;; +;; (push ?\C-\\ exwm-input-prefix-keys) +;; +;; It's also required (and error-prone) to setup environment variables to +;; make applications actually use this input method.

Install XELB and EXWM, and make sure they are in `load-path'. +;; 2. In '~/.emacs', add following lines (please modify accordingly): +;; +;; (require 'exwm) +;; (setq exwm-input-global-keys `(([?\s-r] . exwm-reset))) +;; (exwm-enable) +;; +;; 3. Add the following lines to '~/.xinitrc': +;; +;; exec emacs +;; +;; 4. Launch EXWM in a console (e.g. tty1) with +;; +;; xinit -- vt01 +;; +;; You should additionally hide the menu-bar, tool-bar, etc to increase the +;; usable space.
