Support alt text as short caption for Latex

[hadim]

Using this patch (jgm/pandoc#2447) allow to use image alt text to convert in latex short caption. When it is used with pandoc-crossref, the short caption becomes empty...

See :

![My long caption](figure.png "SHORT CAPTION"){#fig:figure-label}

produces

\begin{figure}[htbp]
\centering
\includegraphics{figure.png}
\caption[]{\label{fig:figure-label}My long caption}
\end{figure}

Instead of :

\begin{figure}[htbp]
\centering
\includegraphics{figure.png}
\caption[SHORT CAPTION]{\label{fig:figure-label}My long caption}
\end{figure}

Any idea to fix it ?

With latex output, pandoc-crossref writes raw latex. So to fix this, one
needs to patch pandoc-crossref. I will try to take a look later this week.

I have the feeling there is something to do there :

pandoc-crossref/src/Text/Pandoc/CrossRef/References/Blocks.hs

Line 39 in a8110d8

RawInline (Format "tex") ("\\label{"++label++"}") : alt

but I suck too much in Haskell to be able to fix it. If you guide me I can maybe try to propose a patch.

If you think it involves too much work, I'll let you do it later this week.

At first glance line 41 should probably have "fig:" ++ snd img instead of
"fig:".

return $ Para [Image alt' (fst img, "fig:" ++ snd img)] produces the following :

\begin{figure}[htbp]
\centering
\includegraphics{figure.png}
\caption[fig:]{\label{fig:figure-label}My long caption}
\end{figure}

and return $ Para [Image alt' (fst img, "fig:" ++ "test" ++ snd img)] produces:

\begin{figure}[htbp]
\centering
\includegraphics{figure.png}
\caption[testfig:]{\label{fig:figure-label}My long caption}
\end{figure}

Seems weird to me... is haskell an inverted language ?

[lierdakil]

That's probably Pandoc, not Haskell. I don't have immediate access to
Pandoc's source ATM, so I'm not sure what's going on. Note that Pandoc's
document model uses "fig:" prefix for implicit figures, so it probably
shouldn't end up in LaTeX output...

Ok. Thanks anyway. I will wait for a fix then !

[lierdakil]

Ok, so 9ef29f9 should fix this. Sorry about misleading you, I kinda forgot my own code 😅 Would be great if you could test with jgm/pandoc#2447 before I publish a release.

[hadim]

It works like a charm ! Thank you.

However there is a little issue and I can't tell wether it is related to pandoc-crossref or pandoc.

String inside short caption does not seems to be parsed by pandoc. For example a short caption (inside []) such as test _italic_ is not rendered with italic style but as test _italic_.

Any idea ?

[hadim]

After some tests, it seems related to pandoc. I will report on jgm/pandoc#2447

Thanks again @lierdakil !

[lierdakil]

Yep, that's expected. Pandoc doesn't parse image title as markdown (I think that's primarily due to "title" being an html attribute, which can't have rich formatting)

[hadim]

Ok I guess I can live with that :-)

I close

FYI, 9ef29f9 published as 0.1.5.5
