Well I looked it up and did not find anything much on the C-lisp
interface. The lisp article: http://en.wikipedia.org/wiki/Lisp_programming_language
is a bit more detailed.
Anyhow let me try in ever so brief:
We start with some of the most basic editor-y things, say buffers and
windows -- which respectively manipulate and show text. Now as a C
programmer you will think of this essentially as two types, struct
buffer {...}; and struct window {...}; and along with that an API to
do the things you want to to them. Now a C++ programmer goes one step
further and binds the the API with the struct (and struts about
calling this an object :-) )
Stallman went one step further and asked What would it take to embed
this API+type fully embedded in its own dedicated language? And you
get elisp.
Well... That emphasised the e part of elisp more than the lisp. For
the lisp part you should study some of the model scheme
implementations -- a bit different from lisp but better for study.
But before that you will also have to study lisp as a language. The
bible today is SICP http://mitpress.mit.edu/sicp/
I myself prefer older books like Allens anatomy of lisp and
Henderson's Functional Programming but these are hard to get nowadays.
Last: Dont give up. The high from lisp cannot be easily replicated.
