Hello,
Incidentally, because I had removed `paredit.el' from my load-path,
I could not export any Org file anymore which contained just one simple
`emacs-lisp' code block, such as:
--8<---------------cut here---------------start------------->8---
* ECM
Type:
#+begin_src emacs-lisp
M-x load-library RET ox-beamer RET
#+end_src
--8<---------------cut here---------------end--------------->8---
I found the culprit lines being:
--8<---------------cut here---------------start------------->8---
;; Common Lisp editing extensions
(autoload 'redshank-mode "redshank"
"Minor mode for restructuring Lisp code (i.e., refactoring)." t)
(add-hook 'emacs-lisp-mode-hook 'turn-on-redshank-mode)
--8<---------------cut here---------------end--------------->8---
because:
- Redshank requires ParEdit, and
- ParEdit was not found anymore.
What I don't understand is:
Why are Emacs Lisp minor modes loaded for exporting
the Org document to HTML?
If not necessary, this seems suboptimal (performance-wise).
Is it really necessary? I don't think so, because if I comment the
Redshank activation, then I can still export to HTML as before. I just
loose the editing features in my real Emacs Lisp buffers.
So, is there a way to disactivate those minor modes during export?
Best regards,
Seb

org-export-format-source-code-or-example loads the mode associated with
the language in org-src-lang-modes in order to fontify the block. You
could check if org-export-current-backend is nil before loading anything
that you want to use only interactively.
Maybe like so?
(add-hook 'emacs-lisp-mode-hook (lambda ()
(unless org-export-current-backend
(turn-on-redshank-mode))))

Hello Sacha and Nicolas,
Answering after a (too) long time with very intermittent Internet
access...

Only to fontify, not to indent, right?

This seems to be a solution (although I did not test it), but it seems
as well impractical: I'd have to chase almost all minor modes of all
languages...
Can't we assume that the major modes have all the information to fontify
the code blocks, and -- if yes -- have a manner to forbid loading all
the minor modes at once (as, then, they'd be completely useless for the
export process)?
Best regards,
Seb

As a final filter, `set-auto-mode' is called in order to indent the
buffer properly. See `org-html-final-function'. When the major mode
switch happens, all associated minor modes are installed.
It also happens when exporting to a temporary buffer.
Of course, this doesn't explain why Emacs lisp minor modes are attached
to an HTML buffer. I guess there is something funny happening with
`set-auto-mode'.

Not really. We could be more careful when generating code, i.e.,
we could generate code already indented.
Another option is to change major mode only when `org-html-indent' is
non-nil.

Not at the moment.

Err, I'm wide of the mark. Sacha is right.
