[SOLVED] \hyperlink raise an error inside \caption #2490

hadim · Oct 28, 2015

\hyperlink introduced in d5efa9b does not place nicely with \caption command and raise this kind of error :

! Argument of \caption@ydblarg has an extra }.
<inserted text> 
                \par

An easy fix is to use is to use \protect wich fix the issue. I tested the following diff and it works for me :

$ git diff
diff --git a/src/Text/Pandoc/Writers/LaTeX.hs b/src/Text/Pandoc/Writers/LaTeX.hs
index 9b345fc..7cbfce9 100644

@jgm, since the diff is really small, I don't open a PR and let you do the commit.

I have a question related to citation. Why does the citation links only applied on the year and note the whole citation ?

Well, you can have citations like [Smith 1980, 2000, 2007] where each year links to a different bib entry.
