Here's an excerpt from xev output from me typing "¤xo", which is to say, Compose x o x o. What you can see from this:

1. The keystrokes eaten by the Compose key still appear as KeyPress and KeyRelease events. They just have XFilterEvent=True on the KeyPress events. The other keystrokes (and the KeyRelease events) have XFilterEvent=False.
2. The ¤ character is injected as a fake KeyPress, with keycode 0 and a keysym corresponding to the actual Unicode code point. I tried ☺ later; the corresponding keysym is keysym 0x100263a, U263A.
3. I believe that all of this compose-key hackery is being done by Xlib, not by the X server, because you have to start a new X client in order to get it to notice changes to .XCompose.

This version doesn’t yet implement template parsing or a reasonable
way to feed in template parameters (e.g. JSON).

I decided to do this entirely with polymorphic variants to familiarize
myself with them, and without any type declarations, but I did cheat a
little bit: in one place I use an ordinary list instead of faking one

Primer curso de Escuela Newton. Serán 8 clases sobre los conocimientos mínimos necesarios para poder trabajar cómodamente en cualquier sistema operativo de la familia Unix (en particular Linux - Ubuntu) Dictado por Javier Sitaker. 8 Clases. Comienza el 5 de Marzo de 2012. Mas info: [email protected]

Resumen Del Curso

Lamentablemente, un montón de nuestros sistemas actuales Unix están en otro mundo, diferente del de las interfaces de Web y GUI que usamos cotidianamente --- un mundo subterráneo debajo del iPhone, Android, Kindle, Mac, casi todos los servidores, y los desktops de software libre. Éste curso te abre las puertas a todo ésto.
