Subject: Bug: LaTeX: inline maths expression in \textrm is not fully supported
Date: Sun, 13 Dec 2020 02:30:15 +0100	[thread overview]
Message-ID: <87h7oq1oig.fsf@ens-lyon.fr> (raw)

Sometimes, we want to nest inline maths expression in \textrm to
handle spaces easily and avoid repetition.

Examples:

1. $A = \{n : \textrm{$n$odd in$X$}\}$
2. $A = \{n : \textrm{$$n$$ odd in $$X$$}\}$
3. $$A = \{n : \textrm{\(n$$ odd in $$X$$}\}\)
4. $$A = \{n : \textrm{n odd in X}\}$$

are all equivalent to

- $A = \{n : n \textrm{ odd in } X}\}$

But Org mode exports them in LaTeX as

\begin{enumerate}
\item \$A =$\backslash${n : \textrm{$n$odd in$X$}$\backslash$}\$
\item $$A = \{n : \textrm{\(n$$ odd in $$X$$}\}\)
\item $$A = \{n : \textrm{\(n$$ odd in $$X$$\}$\backslash$}$\backslash$)
\item $$A = \{n : \textrm{n odd in X}\}$$
\end{enumerate}

Namely, only cases 2. and 4., where nested maths delimiters are different
than the outer-most maths delimiters, are correctly exported.
On the other hand, Cases 1. and 3. introduced extra $\backslash$.

Interestingly, display style maths expressions are correctly exported.

5. $$A = \{n : \textrm{n odd in X}\}$$
6. $$A = \{n : \textrm{$$n$$ odd in $$X$$}\}$$
7. $A = \{n : \textrm{$$n$$ odd in $$X$$}\}$
8. $A = \{n : \textrm{n odd in X}\}$

exports to

\begin{enumerate}
\item $$A = \{n : \textrm{n odd in X}\}$$
\item $$A = \{n : \textrm{$$n$$ odd in $$X$$}\}$$
\item $A = \{n : \textrm{$$n$$ odd in $$X$$}\}$
\item $A = \{n : \textrm{n odd in X}\}$
\end{enumerate}

without extra $\backslash$.

Best,

Firmin
