*Bug: LaTeX: inline maths expression in \textrm is not fully supported@ 2020-12-13 1:30 Firmin Martin2020-12-13 10:24 ` Eric S Fraga 0 siblings, 1 reply; 3+ messages in thread From: Firmin Martin @ 2020-12-13 1:30 UTC (permalink / raw) To: emacs-orgmode 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 $\backslash$.

As soon as you have complex LaTeX, it's best to be explicit about it being LaTeX, e.g.: 1. @@latex:$A = \{n : \textrm{$n$ odd in $X$}\}$@@ HTH, eric -- : Eric S Fraga via Emacs 28.0.50, Org release_9.4-160-g7c8dce ^ permalink raw reply [flat|nested] 3+ messages in thread

This does work for LaTeX export, but if one would also want to export in HTML, the LaTeX expression is lost. I will stay with the "multiple \textrm" solution for now.
