Hello all-
When trying to export via latex -> pdf, the following org-mode snippet
fails to compile. Presumably there's something that should be changed
in the export filters?
Here's the org-mode snippet:
---------------------
*** [[http://www.example.com:90/search~S2?/Xsearchterm&searchscope%3D2&SORT%3DD/Xsearchterm&searchscope%3D2&SORT%3DD&SUBKEY%3Dsearchterm/1%252C742%252C742%252CB/frameset&FF%3DXsearchterm&searchscope%3D2&SORT%3DD&16%252C16%252C][Title
(mediatype) / Publisher]]
---------------------
Relevant generated tex code:
---------------------
\subsubsection{\href{http://www.example.com:90/search~S2?/Xsearchterm&searchscope=2&SORT=D/Xsearchterm&searchscope=2&SORT=D&SUBKEY=searchterm/1%2C742%2C742%2CB/frameset&FF=Xsearchterm&searchscope=2&SORT=D&16%2C16%2C}{Title
(mediatype) / Publisher}}
\label{sec-1-6-1}
(Does this work?)
---------------------
Relevant snippet from the latex log:
---------------------
Runaway argument?
{\href {http://www.example.com:90/search~S2?/Xsearchterm&searchscope=\ETC.
! File ended while scanning use of \@xdblarg.
<inserted text>
\par
<*> /tmp/test.tex
! Emergency stop.
<*> /tmp/test.tex
! ==> Fatal error occurred, no output PDF file produced!
Transcript written on .//test.log.
---------------------
I'm using org-mode release_8.0.5-316-g878d6c. Let me know if you have
any ideas on what is going on, and how to make this work correctly.
Regards,
Mark

Hi Mark,
I confirm this bug: "%" in links breaks the export.
The attached patch is a quick fix, but it needs to be double-checked
and surely amended. Also, I didn't check other link-related functions.
Thanks for reporting this bad bug,

Actually, some characters need to be escaped when used in a URL within
a \href command, but not all of them. `org-latex-plain-text' escapes too
many of them and `org-link-escape' doesn't escape enough (and we don't
need to rely on it).
According to hyperref documentation # and ~ need not be escaped. Though,
%, { and } do. I'm not sure about \, ^ and _.
Also, I don't think \url command has the same problem, so escaping can
happen later in the function, not at the `raw-path' level.

Please feel free to go ahead with whatever fix is better, I was just
trying to quickly reproduce the bug.

I will have a look at it, but this is not clear to me either. I still
have to understand what should be escaped, and when.

A quick related observation. Consider this Org-mode link:
[[https://commons.wikimedia.org/wiki/File:Lysenko-Lullaby_(%C2%AB%D0%9F%D1%96%D1%81%D0%BD%D1%8F_%D0%BF%D1%80%D0%B8_%D0%BA%D0%BE%D0%BB%D0%B8%D1%81%D1%86%D1%96%C2%BB).ogg][https://commons.wikimedia.org/wiki/File:Lysenko-Lullaby_(«Пісня_при_колисці»).ogg]]
The LaTeX code it generates:
\href{https://commons.wikimedia.org/wiki/File:Lysenko-Lullaby_(«Пісня_при_колисці»).ogg}{\url{https://commons.wikimedia.org/wiki/File:Lysenko-Lullaby}$_{\text{(«Пісня}_{\text{при}}_{\text{колисці»}}\text{)}}$.ogg}
Or if I add a "#+OPTIONS: ^:nil" line, then LaTeX code will be the following:
\href{https://commons.wikimedia.org/wiki/File:Lysenko-Lullaby_(«Пісня_при_колисці»).ogg}{\url{https://commons.wikimedia.org/wiki/File:Lysenko-Lullaby}\_(«Пісня\_при\_колисці»).ogg}
I.e. it wraps only part of the description of the link with \url due
to the parentheses in it.

One more thing, related to unicode inside the href of the link:
[[https://commons.wikimedia.org/wiki/File:%D0%91%D1%83%D0%B7%D0%BE%D0%BA.ogg][https://commons.wikimedia.org/wiki/File:Бузок.ogg]]
Turns into:
\href{https://commons.wikimedia.org/wiki/File:Бузок.ogg}{\url{https://commons.wikimedia.org/wiki/File:Бузок.ogg}}
I.e. for some reason the href gets url-decoded. Such links don't work in evince.

This is to be expected. Only the beginning of your description part
matches `org-plain-link-re' and gets converted to a link.

Indeed, links are url-decoded when parsed (see line 3139 in
org-element.el). I think the reasoning behind it is that url should then
be encoded again to make sure every url is correctly encoded.
One possibility is to use (org-link-escape (org-link-unescape
raw-link)), that is every parsed link will be url-encoded. Another one
is to leave links as-is, but back-end developers will have to deal with
that. I lean towards the former.
Funnily, this only applied to bracket links (i.e., [[link][desc]]),
plain links are not url-decoded (or encoded) at all. This isn't
consistent and also needs to be fixed.
Any opinion?

I cannot reproduce the bug anymore. Can you?
