Well, you could use the Lua ‘read’ function to read in a snippet consisting of the macro definitions + the math. e.g. pandoc -f latex -t native \newcommand{\pie}{\pi} $\pie^2$ ^D [ Para [ Math InlineMath "\\pi^2" ] ] > On Jan 17, 2023, at 11:17 AM, bapt a wrote: > > Hi, > > I've found it useful in some situations to expand all custom LaTeX macros (such as `\newcommand{\Curl}{\nabla\times}`, for example) in a document before rendering it. > For example, with Quarto being used to produce a book in both pdf and html formats, the macros stored in a file `_macros.tex` are processed differently in the LaTeX path (simply including `_macros.tex` in the preamble) and in the Html version (where Mathjax needs to be given such macros for every page that it renders; it doesn't work to provide it once for the whole book/website). > > An alternative that sounds quite robust would be to run something like de-macro (https://www.ctan.org/tex-archive/support/de-macro) on the source document before it is rendered: the macros are still used for convenience of writing in the input file, but they get expanded explicitly before LaTeX or Mathjax is asked to render. > > Unfortunately, de-macro is a Python script, and might be a little fragile as it processes whole documents with regex. I wonder if achieving the same thing would be easier with a Lua filter in pandoc? Presumably, having already all the equations isolated in the AST makes life a bit easier, and I believe there is already a mechanism in pandoc to process and expand `\newcommand` directives for non-latex output. Is this mechanism available to a Lua filter that could be used in a Quarto workflow? > > Many thanks, > > baptiste > > > > > > -- > You received this message because you are subscribed to the Google Groups "pandoc-discuss" group. > To unsubscribe from this group and stop receiving emails from it, send an email to pandoc-discuss+unsubscribe-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org . > To view this discussion on the web visit https://groups.google.com/d/msgid/pandoc-discuss/a5d780b9-2dcc-4cc4-bade-29bae4777811n%40googlegroups.com . -- You received this message because you are subscribed to the Google Groups "pandoc-discuss" group.
