set modes for org-edit-special (elisp block)

set modes for org-edit-special (elisp block)

[Stefan Huchler]

Hi,

org-edit-special opens elisp code with emacs-lisp mode, which is not
bad, but I wanted to try out xah-elisp-mode for am while.

tried to overwrite or shadow the settings with something like

(add-to-list 'org-src-lang-modes '("xah-elisp" . emacs-lisp))

am I here at the right place to change that behaviour?

Looks like you've got the right variable, but the key should be the
language name and the value should be major mode you want.

    ("elisp" . xah-emacs-lisp)

I changed it a few times and I think I had it this way first, do I have
to reload org after it? I closed the file and reopened it did not help.

But I can try it again with that, maybe I really did not have it that
way.

Once you've modify org-src-lang-modes, it should work.  Since I don't
have xah-emacs-lisp-mode installed, I've just tested it with
python-mode.

  (add-to-list 'org-src-lang-modes '("elisp" . python))

After evaluating above, org-edit-special opens up

  #+begin_src elisp
    import sys
  #+end_src

in python-mode.

Shouldn’t it be "xah-elisp" (the mode is "xah-elisp-mode"). I gave it
a try and it’s also not working out of the box for me. I also restarted
emacs, to no avail.

Right, sorry.  It should be whatever the mode name is, minus "-mode".
Is it just xah-elisp-mode that is giving you a problem?  Did you try
with the example I gave in my previous message ($gmane/104430)?

I’m having the same problem with python: I’m still in emacs-lisp mode.
I checked the value of the variable and it is as expected. For some
reason the change is not picked up. Is it because there are several
occurrences of "elisp" in the list and it’s not the first one that is
picked up?

I’m using a fairly current org (compiled last week from master).

No, I don't think repeated keys are an issue as long as the one you want
occurs first.  (org-src--get-lang-mode uses assoc.)  It really should
just boil down to

   (cdr (assoc "elisp" org-src-lang-modes))

Perhaps you step through org-src--get-lang-mode (which is called by
org-edit-src-code) to see what's going on.

org-src--get-lang-mode uses assoc, so it should pick up the first pair
whose car matches. You can try it by hand:

(org-src--get-lang-mode "elisp")

Of course, it's possible (but unlikely) that somebody is using some
other way to get at the mode.

I finally found the source of my problem, and I feel very stupid: my
elisp blocks use the name "emacs-lisp" as language, so this
customization was not picked up, since "elisp" and "emacs-lisp" are
different.

Sorry for the confusion,

Alan
