Hi,
Is there a simple way to build regex-based extensions to the exporters?
For example, I would like to convert this string "=>" to $\rightarrow$
when converting the document to latex.
There are lots of other uses, where I could create my shortcuts and
insert them in orgmode files without creating a lot of clutter in the
file.
Sebastian

I like this idea. It would be ideal if one could define these in the
header of the org document - easy to maintain and to edit.

There's an example of how to do something like this in the "Advanced
Configuration" section of the Export section in the manual. Maybe you
could adapt it like this?
(defun my-latex-filter-rightarrow (text backend info)
(when (org-export-derived-backend-p backend 'latex)
(replace-regexp-in-string "=>" "$\rightarrow$" text)))
(add-to-list 'org-export-filter-plain-text-functions
'my-latex-filter-rightarrow)
Hope that helps!
Best,
Richard

That works very well. Thank you very much. The only adjustment is to set
LITERAL to non-nil for replace-regexp-in-string and use double backslash.
(defun my-latex-filter-rightarrow (text backend info)
(when (org-export-derived-backend-p backend 'latex)
(replace-regexp-in-string "=>" "$\\rightarrow$" text nil t)))
I'm still undecided between a regex replace and org-entities. Is there
a straightforward way to define own directives for orgmode to then
support something like the following?
#+LaTeX_EXPORT: "=>":"$\rightarrow$"
or more generic
#+EXPORT_EXPAND: latex:"=>":"$\rightarrow$"
Then I could just make these expansions part of the standard header in
my org files.

Well, there are macros, which do something very similar. As far as I
know, they are the only way to achieve this kind of thing without some
Elisp.
You could do something like:
#+MACRO: => @@latex:$\rightarrow$@@
but that actually doesn't seem to work as is, I suspect because "=>" is
not an allowable macro name. (It works fine with an alphabetic name
like "ARR".) But even if you got it to work, you'd then have to type
Some text {{{=>}}} other text after the arrow
in your document, which sort of defeats the point of the nice, simple
"=>". If it were me, I'd opt for the regex replacement, and avoid
typing all the braces.
Best,
Richard

Yeah, filters. But I don’t think this is the best way to go about it.

This sounds a bit like org-entities. I use this together with cdlatex for
quickly inserting such things.
Try to type \Rightarrow and type C-c C-x \
Also try to export to text (non-unicode). You will get the desired symbol.
Alternatively, you can use one of the many input methods such as TeX or
rfc1345 in which case you can get the ‘⇒’ by typing ‘\Rightarrow’ or
‘&=>’, respectively. In latex, you can setup unicode-math.
Hope it helps,
Rasmus

Great - learned something. Never knew about org-entities.
Would it be possible to generate *easily* a pdf with all the org-entities?
Possibly include it in org as a kind of a cheat-sheet for org-entities?
Reading the help in this case is possible but not easy...

Might be nice... The styling would be essential.
For personal use you might experiment with the below function?
(I didn't try the resulting latex file).
(defun rasmus-org-entities-as-latex (file)
(with-current-buffer (or (get-file-buffer file)
(find-file file))
(erase-buffer)
(insert (mapconcat (lambda (e)
(format "- =\\%s= :: \\%s \n"
(nth 0 e)
(nth 0 e)))
(remove-if-not 'listp
(append org-entities-user org-entities))
""))
(save-buffer)))
(rasmus-org-entities-as-latex "/tmp/entities.org")

That's interesting, because it's more robust to add something to the
org-entities-user list than to regexp replace a portion of the whole
document.
However, there are two disadvantages to org-entities: (1) they have to
start with a backslash (e.g., \Rightarrow) and (2) they don't seem to
support alphabet-based names, so this doesn't work:
(add-to-list 'org-entities-user '("=>" "\\rightarrow" t "=>" "=>" "»" "»"))

Correct.
You can add a hook to ‘org-export-before-parsing-hook’ to have a list of
non-standard entities that are to be changed into "correct" entities
beforehand, e.g. (("=>" . "\\rightarrow")).
Or you can use something like cdlatex to quickly insert the "correct"
entities, e.g. "\Rightarrow" is inserted with "’]" in my setup. The added
benefit is that entities work out of the box so when I’m exporting on
another computer it just works.
