How to get code line numbers inside page margins?

[MohamedEmary]

I'm using pandoc to generate PDFs from markdown files, when i write a code block with line numbers using {.lang .numberLines} the line numbers goes outside page margins like that:

Is there anyway to fix that.

I tried searching for this issue but most of the answers like this one were for how to fix that behavior when writing pure latex not pandoc flavored markdown.

We're using a customized fancyvrb Verbatim environment, so see fancyvrb's documentation.

You could try the following diff in the default template:

- \DefineVerbatimEnvironment{Highlighting}{Verbatim}{commandchars=\\\{\}}
+ \DefineVerbatimEnvironment{Highlighting}{Verbatim}{commandchars=\\\{\},xleftmargin=1.5em}

Sorry, forgot that that line is not in the template, because it is supplied by skylighting.
In that case, you can try adding this to header-includes:

\RecustomVerbatimEnvironment{Highlighting}{Verbatim}{commandchars=\\\{\}, xleftmargin=1.5em}
