Subject: Re: caption width in LateX export

P.S.: I have come up with another possibility, more automatic, on the
LaTeX side, if you compile with LuaTeX. This thread
(https://tex.stackexchange.com/questions/202046/width-of-the-caption-of-a-figure),
where someone proposes to use a \savebox for concrete images, gave me
the idea. We can automate that through a simple function in Lua, and add
it to the `process_input_buffer' callback, in order to the caption
*always* has the width of each image:

You can put this in your Org document:

#+NAME: luacode
#+begin_src latex :exports none
\usepackage{luacode}

\begin{luacode*}
  function caption_width ( text )
  text = string.gsub ( text, "(\\includegraphics.+)", "\\sbox0{%1}")
  text = string.gsub ( text, "(\\caption{.+})", "\\begin{minipage}{\\wd0}\\usebox0%1\\end{minipage}")
  return text
  end
\end{luacode*}

\newcommand\CaptionAutoWidth{\directlua{luatexbase.add_to_callback
( "process_input_buffer" , caption_width , "caption_width" )}}

\AtBeginDocument{\CaptionAutoWidth}
#+end_src

#+begin_src latex :noweb yes :results raw
,#+LaTeX_HEADER: <<luacode>>
#+end_src

And then:

#+CAPTION: Lorem ipsum dolor sit amet, consectetuer adipiscing elit
#+ATTR_LaTeX: :width .3\linewidth
[[img]]

Best regards,

Juan Manuel
