Dynamix HTML preamble/postamble

Dynamix HTML preamble/postamble

[Julien Barnier]

Hi,

I'm currently migrating a bunch of files from Muse to Org (not that
Muse was not a good project, but I'd like to minimize the number of
keyboard shortcuts to remember :-) ).

One thing that I miss in Org is the ability to dynamically generate
the pramble and postamble during HTML (or LaTeX) export. In muse you
can provide a lisp function that is evaluated per file and which is
able to access file options with muse-publishing-directive.

Is there a contrib or a method to do such a thing in Org mode ?

Thanks in advance for any answer, and thanks for this *great* Emacs
mode !

Sincerely,

-- 
Julien

Hi Julien,

There is `org-export-preprocess-hook' which is run over your org file
before the file is exported (to latex, html, or ascii).

,----`org-export-preprocess-hook'
| org-export-preprocess-hook is a variable defined in `org-exp.el'.
| Its value is 
| (org-export-blocks-preprocess)
| 
| 
| Documentation:
| Hook for preprocessing an export buffer.
| Pretty much the first thing when exporting is running this hook.
`----

If you add a function to this hook it would have access to the
parameters set in the org file through the `parameters' alist, see
`org-export-preprocess-string' in org-exp.el for more information.

As for changing the preamble and postamble, I don't know if these are
variables which could simply be overridden (which would be nice), or if
you would want to insert these in the buffer inside of #+begin/end_html
blocks.

If you come up with a generally useful function please be sure to share
it.

Good luck -- Eric
