Hi all,
When a line of babel source code starts with leading star
(also some other characters, see `org-unescape-code-in-string')
org-mode auto-escapes it with a comma.
I assume that there's no easy way not to add the comma.
But I think it should be possible to fontify it as if it's not there.
This comma is auto-removed for purposes of evaluation
or when switching to native mode to edit a source block.
The issue is that it's not removed when viewing the org-file.
Small example to illustrate: J souce "*/ 2 2" displays as
#+begin_src J
,*/ 2 2
#+end_src
I've found a work around:
(defvar keyword-comma-star
'(("^\\(,\\*\\)" (1 (prog1 ()
(compose-region (match-beginning 1)
(match-end 1)
?*))))))
(font-lock-add-keywords 'org-mode keyword-comma-star)
Is this good enough to add to org-babel core?
Maybe someone has a different option to fix the issue?
regards
Oleh

I think it's a good candidate for
http://orgmode.org/worg/org-hacks.html
but the default should be to display the comma so that users
know it's here.
2 cents,
