Subject: [PATCH] ox-latex: Replace \verb instances in headings with \texttt
Date: Wed, 31 Mar 2021 23:14:35 +0800	[thread overview]
Message-ID: <87mtujfj8k.fsf@tecosaur.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 448 bytes --]

Hello again,

This time with a smaller patch that works around LaTeX peculiarities.
When LaTeX encounters \verb inside another command it's expanding, it
can panic and compilation fails.
This occurs inside \section commands, and so it's worth modifying the
default header format function to convert any instances of \verb to
\texttt, as that can actually compile successfully.

See https://www.texfaq.org/FAQ-verbwithin for more info.

Subject: [PATCH] ox-latex: convert verbatim text in headings to tt

* lisp/ox-latex.el (org-latex-format-headline-default-function): Convert
any instances of \verb text with \texttt.  This is required to work
around LaTeX peculiarities that would otherwise cause compilation to
fail (see the code comment for more information).
