There are a few fundamental data structures that Emacs uses
that are quite
complex and variable in form. I'm thinking of things like
keymaps (including
menus), font-lock-keywords, and faces/text properties.
I did a lot of work on the keymap documentation in response
to your last suggestion. Is there any part of it which is
still insufficient?
I doubt it. As far as reference material goes, it is good: accurate,
complete, concise.
I was suggesting more user-guide material or a tutorial - something along
the lines of the Emacs-Lisp Intro (but short). I suspect that only a
relatively small number of Emacs-Lisp programmers are comfortable with
keymaps in all their forms, and I think it would help Emacs development
(including 3rd-party features) for more people to be familiar with them.
That was the motivation.
I think the documentation of font-lock-keywords is complete.
I agree it is hard to grasp, but I don't know how to make
it clearer. Does anyone else have an idea?
Yes, it is probably complete. I was speaking only to the hard-to-learn part.
The best help is provided by walking a reader through examples. Examples are
the place to start. Again, see the Emacs-Lisp Intro for a good presentation
model.
As for faces and text properties, they are very simple structurally.
They are just plists. What aspect of them do you find complex?
I don't know. I recall trying to wade through some code that examined font
specs (with defaulting, inheritance, merging etc.), and it seemed complex.
Perhaps it had to do with face-spec-reset-face and set-face-attribute. I
don't remember.
