Is there an emacs c code document ?

Is there an emacs c code document ?

[Kyle M. Lee]

Hi all,
I am very interested in emacs internal implementation, especially the c
code. And I have gotten the cvs emacs 23 code. I googled with "emacs
internal", found nothing valuable. So I asked this question, are there
some nice documents or guide about the emacs internal implementation ?

Maybe someone would tell me, the code is the real document.:) The emacs
code is not doxygen-like. So I am reading code with emacs + ECB.

Any comments are welcome.

In addition to the code itself, there are a few documents in
admin/notes. I thought there was something about garbage collection
there, but it must be somewhere else.

Is there an emacs c code document ?

The XEmacs Internals Manual
http://www.xemacs.org/Documentation/21.5/html/internals.html
may be of some use for general coding conventions and techniques.  The
Mule code is quite different, as are the internal console APIs.  But
the coding conventions for the Lisp engine are pretty similar.

There is also the "the craft of text editing" book
(http://www.finseth.com/craft/), which is very old and doesn't describe
Emacs's code, but can still be relevant in giving an idea of the
general organization.

And if you have detailed questions, this mailing list may answer them,
of course.

Nice book. I will read it and the XEmacs Internal document that Stephen
gave. Thanks.

In addition to all the good advice others gave you, I'd like to
mention the node "GNU Emacs Internals" in the ELisp manual.  While it
doesn't really describe the C code, it does give you some good
background about how the fundamental Emacs objects work.

Thanks, Eli. That's what I want too.
The info of emacs likes forest. :)
