Pandoc does know how to expand LaTeX macros. For example, given the LaTeX \newcommand{\pair}[2]{\langle #1, #2\rangle} $$\pair{a^2}{\frac{\pi}{2}}$$ pandoc will give you the Typst $ chevron.l a^2 \, pi / 2 chevron.r $ which is correct. Tylax, on the other hand, seems to have problems with this example, producing $ angle.l^()frac(pi,)angle.r $ which does not compile with typst. Going the other direction, pandoc also understands typst scripting. For example, from #let count = 8 #let nums = range(1, count + 1) #let fib(n) = ( if n <= 2 { 1 } else { fib(n - 1) + fib(n - 2) } ) The first #count numbers of the sequence are: #align(center, table( columns: count, ..nums.map(n => $F_#n$), ..nums.map(n => str(fib(n))), )) pandoc produces this LaTeX: The first 8 numbers of the sequence are: {\def\LTcaptype{none} % do not increment counter \begin{longtable}[]{@{}llllllll@{}} \toprule\noalign{} \endhead \bottomrule\noalign{} \endlastfoot \(F_{1}\) & \(F_{2}\) & \(F_{3}\) & \(F_{4}\) & \(F_{5}\) & \(F_{6}\) & \(F_{7}\) & \(F_{8}\) \\ 1 & 1 & 2 & 3 & 5 & 8 & 13 & 21 \\ \end{longtable} } With the same input, Tylax produces: The first 8 numbers of the sequence are: \begin{center} \begin{tabular}{|c|} \hline \hline \end{tabular}\end{center} which is just an empty table.
