Can an 'Abstract' parameter be passed to pandoc to create a latex file? [closed]

Question

Similar to $title$, $author$, and $date$, is there an $abstract$ parameter that one can pass to a latex file from the title block? Example:

\begin{abstract}
    $abstract$
\end{abstract}

Answer 1

I had a look at the documentation and found out that you can easily set new variables. Sadly, I don't think pandoc is able to automatically extract custom variables, since the documentation states that some variables are automatically set, other aren't.

We can extend default.latex from $PANDOC_HOME/templates to include an abstract verification. I made a copy from https://github.com/jgm/pandoc-templates/blob/master/default.latex and added the following code before the $body$ markup:

...    
$if(abstract)$

\begin{abstract}
$abstract$
\end{abstract}
$endif$

$body$
...

I saved my new file as article.latex. Now I can call:

$ pandoc --template=article.latex --variable abstract="I'm an abstract" INPUT -o OUTPUT.tex

The new block

\begin{abstract}
I'm an abstract
\end{abstract}

will be available in the generated file.

Hope it helps. :)
