Add an option for -shell-escape

[protz]

Hi,

Would it be difficult to add an option to call LaTeX with the -shell-escape flag when compiling to PDF? My use-case is custom minted blocks that I'm adding directly, and this package requires latex to be called with the flag. Granted, I could generate .tex and then compile it myself, but it would definitely be more convenient to have pandoc add the right flag :).

Thanks,

jonathan

👍 Really need this (might also be of use to add a generic option for extra LaTeX flags).

We now have --latex-engine-opt, so this can be closed.

I get an empty space instead of highlighted LaTeX code with the following code. I have added the minted package in a template. To get the right output, I have to compile the generated TeX file with -shell-escape option before the file name. I was wondering if someone has an example of using -shell-escape that works.

output:
beamer_presentation:
pandoc_args: [
"--latex-engine-opt", "-shell-escape"
]
keep_tex: true
template: src/beamertemplate.tex

fonttheme: structurebold

Basic - Interfaces {.fragile}

\begin{minted}{latex}

\item Here
\end{itemize}
\end{minted}

I don't know what version of pandoc you're using, but
there was a problem with --latex-engine-opt that was fixed
(#1779) in pandoc 1.15.0.5.

I was using 1.15.0.6. and then I updated to 1.15.1.1. The issue was the same.

I assume you're running pandoc via some kind of wrapper
script? Because pandoc-options in YAML metadata is not
support in pandoc.

Yes. I am using RStudio. When I use:
pandoc_args: [
"--latex-engine-opt", "-shell-escape"
]
The -shell-escape option is passed to the latex engine because it generates the PDF file with no error. If I remove the -shell-escape option, I receive an error.

[jgm]

@bsamadi I'm confused about what problem you're encountering, if any.
When using minted, you do need the -shell-escape option, that's true.
And you say it works when you provide this. So, all is well, no?

[bsamadi]

John, I am able to generate the PDF with no error but instead of the highlighted code, I get an empty space. If I compile the generated tex file, I then get the right output. Does the pandoc job finishes with generating the tex file? If that is the case, then the problem is with RStudio and the way it calls pdflatex.

[Lesik]

I have the exact same issue as @bsamadi: There is only empty space. I am running

pandoc % --output=file.pdf --latex-engine=pdflatex --latex-engine-opt="-shell-escape"

No RStudio, just editing the file in vim.

@Lesik I'm not sure, but this is a closed issue.
