Hello dear list,
* Summary
I want to know if someone could tell me how to replace (the macro,
function, string) includegraphics for something else when exporting to
LaTeX. In my case, simplesvg.
* Why
I have my own version of the svg package (I only extracted bits and
pieces from it long time ago), and I want to make clear for others who
may use my files that I'm not using includesvg (I could just change the
definition of simplesvg to includesvg).
* What I have tried
** Stealing from the webz
This does not work. I think that the list doesn't exist in org-mode
anymore:
#+BEGIN_SRC emacs-lisp
;; Export svg (does not work)
;;
https://lists.gnu.org/archive/html/emacs-orgmode/2013-08/msg00221.html
;;
https://github.com/tsdye/tufte-org-mode/blob/master/ox-tufte-latex.el
(defun my-svg-graphics (contents backend info)
(when (eq backend 'latex)
(replace-regexp-in-string
"\\`\\\\includegraphics.+\\({.+\.svg}\\)"
"\\\\simplesvg\1" contents))
)
(add-to-list 'org-export-filter-link-functions 'my-svg-graphics)
#+END_SRC
** Looking into org (ox-latex.el)
I found this (around line 2375 in ox-latex.el):
#+BEGIN_SRC emacs-lisp
(when (equal filetype "svg")
(setq image-code (replace-regexp-in-string "^\\\\includegraphics"
"\\includesvg"
image-code
nil t))
(setq image-code (replace-regexp-in-string "\\.svg}"
"}"
image-code
nil t)))
#+END_SRC
I could just change the code here (simplesvg instead of includesvg), but
before f\#\#cking up my system, I would like to know if there is another
alternative.
Thanks, as always :D !

This made me think of the various times someone wants to use endnotes
instead of footnotes. Have you considered just changing the definition
in LaTeX instead? [1] [2]
#+LaTeX_HEADER: \usepackage{endnotes}
#+LaTeX_HEADER: \let\footnote=\endnote
In other words, utilize the fact that Org already handles images
flawlessly and then just define \includegraphics to be something else
on the LaTeX end of things.

Yes, may be the redaction of my request was not very clear, I'm sorry. I
did not want to do that, because I foresee that someone may think that
my \includesvg is the \includesvg from the svg package. However, the two
do not work in the same way, and may lead to problems.
If my previous e-mail was indeed clear, may be I'm not getting what you
are trying to say, sorry.
Thank you.
Edgar

I initially saw this:
(replace-regexp-in-string "\\`\\\\includegraphics.+\\({.+\.svg}\\)"
"\\\\simplesvg\1" contents))
That looked like you wanted to just swap \includegraphics with
\simplesvg. Doing that via LaTeX directly seemed like an easy way:
#+latex: \let\includegraphics\simplesvg
Now that I'm re-examining, you only want to do this for .svgs so
that's not nearly as straightforward.

If the above *did* work, I don't see why you couldn't just remove the
#+latex line before publishing. Or define it in a setupfile that you
load and no one would ever know the contents to get confused. Or
perhaps it was a mandatory requirement to do zero changes to the file
you publish? The first method you showed appeared to apply elisp code
from within the file, so I'd assume an external user would see it but
have to ignore/not eval.
Filters are intimidating to me (no elisp-fu here!), but they
definitely sound like the ticket!
Good luck,
John
P.S. On a last point re. the confusion alone, I'm interpreting you to
mean users may think \simplesvg == \includesvg? Or simplesvg is your
package *name*, svg is the CTAN package, and they both provide
\includesvg? Why not rename your local version's command to a
different name? Or do \usepacakge{simplesvg} locally, and in the
published version have it commented with a note that it's special? Or
make your package available and include a link and instructions to
replicate? Just seems like an awful lot of work for a naming
convention issue!

This is what filters are for. In your case `:filter-link' needs to have a
function that changes `includegraphics' to `simplesvg', if I get what you
want.
Check out the manual:
(info "(org) Advanced configuration")
maybe run the example here:
http://orgmode.org/worg/exporters/filter-markup.html
and consult the part about filters here:
http://orgmode.org/worg/dev/org-export-reference.html
There are examples in the ox-*.el files, too. So, grep these for
`filters-alist' to see some examples.
HTH,
Chuck

Oh! Thanks! I was unaware of this. I'll try :) .
