[PATCH] ob-latex: Added support for including files with a relative path

[emacs]

Dear list, 

in the attachment you find a proposed patch to support including external files

when exporting a latex source block. Currently this was only possible by using a

:header argument. The problem with this approach is that, files needed to be

included with their absolute path.

My proposed change adds support for a :inputs header argument, which expands te

provided file paths to an absolute path before including them.

Example: 

#+HEADER: :file example.pdf

#+HEADER: :inputs '("./input/preamble.tex")

#+BEGIN_src latex

\begin{tikzpicture}

  \draw[->,custom-style] (-3,0) -- (-2,0)

    arc[radius=0.5cm,start angle=-180,endangle=0] (-1,0) -- (1,0)

    arc[radius=0.5cm,start angle=180,end angle=0] (2,0) -- (3,0);

    \filldraw (-1.5,0) circle[radius=1mm];

    \filldraw (1.5,0)circle[radius=1mm];

\end{tikzpicture}

#+END_src

Expands to 

\documentclass[article]

...

\input{absolute/path/to/input/preamble.tex}

\begin{document}

\begin{tikzpicture}

  \draw[->,custom-style] (-3,0) -- (-2,0)

    arc[radius=0.5cm,start angle=-180,endangle=0] (-1,0) -- (1,0)

    arc[radius=0.5cm,start angle=180,end angle=0] (2,0) -- (3,0);

    \filldraw (-1.5,0) circle[radius=1mm];

    \filldraw (1.5,0)circle[radius=1mm];

\end{tikzpicture}

\end{document}

Kind regards,

Bob
