Troubleshooting
attempt to compare nil with number
warning (node filter): error: ...e/2022/texmf-dist/tex/generic/babel/babel-bid
i-basic.lua:155: attempt to compare nil with number
This bug can be produced by a statement with a custom label containing an uppercase letter followed by a dash, such as:
::: statement
__L-a__. This statement might generate an error!
:::
Fix 1. Put the dash in a \textrm{...} command:
::: statement
__L\textrm{-}a__. This will not generate an error.
:::
This still comes out as a simple dash in formats other than LaTeX.
Fix 2. Surround the dash with spaces
::: statement
__L - a__. This will not generate an error.
:::
A longer dash probably looks better:
::: statement
__L -- a__. This will not generate an error.
:::
If that’s not satisfying, and you don’t want to change the statement label, you will have to change your font or your pdf engine.
Details. This is not a statement filter bug, but a bug within
LaTeX (as of nov 2022). It arises when using the lualatex pdf
engine and certain fonts (e.g. Libertinus and STIX Two Text
generate it, Times New Roman, Helvetica Neue, Avenir don’t).
The bug is a conflict between the amsthm and babel (specifically, I
suspect, its luababel component) packages. It can be generated in LaTeX
itself, e.g:
\documentclass{article}
\usepackage{amsthm}
\usepackage{fontspec}
\setmainfont{Libertinus Serif}
% The error appears with bidi=basic, not bidi=default
\usepackage[bidi=basic]{babel}
\begin{document}
\newtheorem*{statement}{A-b} % generates an error
% \newtheorem*{statement}{{A}-b} % generates an error
% \newtheorem*{statement}{A{-}b} % generates an error too
\newtheorem*{statement}{a-b} % does not generate an error (only upper case letters)
\end{document}
calc needed
The calc package is needed to handle statements placed
within list (itemize/enumerate environements). The default Pandoc
template for LaTeX loads it, but if you use a custom template instead
its preamble should contain \usepackage{calc}.
