Re: [Orgmode] programming for org-mode

[Eric Schulte]

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.
