Re: programming for org-mode

So,

The way that I learned how to program in emacs lisp was mainly using two
commands `elisp-index-search' bound to `C-h e' on my system, and most
importantly `describe-function' bound to `C-h f'.  With
`describe-function' you can look at the source code of functions whose
behavior you are familiar with, you can then copy portions of the code
to your *scratch* buffer where they can be edited and evaluated with
`eval-defun' bound to `C-M-x'.  Now with Babel, instead of doing this in
the scratch buffer you could do this in emacs-lisp code blocks in an org
file, enabling notes and hierarchical organization -- it can be nice to
have your noodling all collected in one file for later reference.

If you are going to do any serious work with lisp, I would emphatically
recommend using paredit-mode, and becoming friends with the Sexp
movement functions

| C-M-f | runs the command paredit-forward  |
| C-M-b | runs the command paredit-backward |
| C-M-u | runs the command backward-up-list |
| C-M-k | runs the command kill-sexp        |
| C-y   | runs the command yank             |

They allow you to manipulate lisp code on the level of logical
expressions, the utility of which can not be over stated.

As for working with Org-mode in particular, I'd recommend looking at the
documentation and source-code of Org-mode functions with
`describe-function', and then looking for how these functions are
actually used in the Org-mode code base with `rgrep'.

For a more structured learning experience, I've heard very good things
about http://www.gnu.org/software/emacs/emacs-lisp-intro/, although I
haven't used it myself.

Hope this helps.  Happy Hacking -- Eric

I'm afraid there is no such thing as an org-mode api, the closest you
could come would be

grep -i defun org/lisp/org.el

for a list of function names and their arguments, or run
`describe-function' then type "org-" into the minibuffer, tab complete,
and then search through the resulting function-names.

If you have any org-collector.el specific questions please let me know.
