Using Pandoc to convert a Latex document that contains unsupported language code (Dart)

[minoush82]

I have the following Latex document (example.tex).

\documentclass[a4paper]{report}
\usepackage{minted}
\begin{document}
	\begin{minted}[linenos, bgcolor=yellow, autogobble, tabsize=4]{dart}
		void main()
		{
			print("I need help!\n");
		}
	\end{minted}

	\begin{minted}[linenos, bgcolor=yellow, autogobble, tabsize=4]{dart}
		// main
		void main()
		{
			print("I need help!\n");
		}
	\end{minted}
\end{document}

I am using the following command to get the HTML output (example.html):
pandoc -s -N --syntax-definition=dart.xml -f latex -t html example.tex -o example.html

Where dart.xml is this one: https://github.com/KDE/syntax-highlighting/blob/master/data/syntax/dart.xml

I get the following warning for each code snippet containing a comment:
IncludeRules in Dart requires undefined context ##Comments

The result is that the code snippets containing comments are not syntax-highlighted. The following is what the generated HTML looks like in a browser. As can be seen, the code snippet with comments has no colors.

Any thoughts?

I think the file: https://github.com/KDE/syntax-highlighting/blob/master/data/syntax/dart.xml references other files such as https://github.com/KDE/syntax-highlighting/blob/master/data/syntax/comments.xml using IncludeRules.
If this is right, is there a way to include all the necessary XMLs using --syntax-definition?

Try just putting comments.xml in the working directory, or in the directory containing dart.xml ?

[minoush82]

This does not work unfortunately.

[jgm]

What if you use --syntax-definition twice with both dart.xml and comments.xml, does that work?

[minoush82]

Yes yes yes! That works! Thank you very much.

The solution to my problem is to use the following command (thanks to @jgm ):
pandoc -s -N --syntax-definition=dart.xml --syntax-definition=comments.xml --syntax-definition=spdx-comments.xml -f latex -t html example.tex -o example.html
