Hi everyone
I guess this is mostly a request for Nicolas, but maybe others would
like to chime in.
Quite often I am in a situation where I want to use filters
to customize the export for a specific file. I was wondering
if it would be useful to support a special source code block
that can contain code that should be executed before export in
a way that a temporary list of export filters is installed
for this specific backend and then removed again.
For example, I would like to have special formatting of
time stamps in a specific file - I could then use this
to install a filter in org-export-filter-timestamp-functions
that would do this special formatting, without influencing
what happens to other exports.
Have I overlooked an easy way to do this, or would this be
something others would like to use as well.
- Carsten

I didn't check, but I think it is possible to set filter through #+BIND
keyword? Otherwise, you can try file local variables.

OK, I'll try this. However, if the code is a bit more extensive, an SRC block would make it more comfortable to maintain this code inside a file. If I want to write a somewhat complex filter function, it is not convenient to do so in #+BIND line.

I can't see why it would be inconvenient, since you needn't define the
filter within the BIND keyword.
Anyway, you can write a source block that sets locally the filters. That
should work too.

OK, I'll give that a try.
Thanks

Indeed, this can be done. Here is an example (thanks also to Eric for
quick help with the export arguments):
* Special export setup :noexport:
#+begin_src emacs-lisp :exports results :results none
(defun my-org-export-filter-timestamp-function (timestamp backend info)
"removes relevant brackets from a timestamp"
(when (org-export-derived-backend-p backend 'html)
(replace-regexp-in-string "&[gl]t;\\|[][]" "" timestamp)))
(make-local-variable 'org-export-filter-timestamp-functions)
(add-to-list 'org-export-filter-timestamp-functions
'my-org-export-filter-timestamp-function)
#+end_src

Can't you identify it by the folder name? Or with a
special #+DESCRIPTION or #+KEYWORDS?
Like this:
#+TITLE: MySpecialFile.org
#+begin_src emacs-lisp
(defun rasmus/match-buffer (text backend info)
"Match only some buffers identified by "
(if (and
(string-match "MySpecialFile" (plist-get info :input-file))
(org-export-derived-backend-p backend 'latex))
"Match!" text))
(add-to-list 'org-export-filter-final-output-functions
'rasmus/match-buffer)
#+end_src
Otherwise I'd also bind the value locally and maintain the code in a
SETUPFILE or in a * lisp :noexport: heading.
