I use Pandoc to generate an output from a Markdown file to many outputs: html, word (.docx), latex, pdf, etc.

I tried using the "fenced div" feature to style differently some parts of the text. For example:


:::: special

Some special text, with markdown formatting.


To style that block with Html, it's fairly straight forward. I have a template.css file that includes a .special {background-color: #aaaaaa;} line and it's done (it's referenced in my command line arguments).

I also have a template.latex file, but I'm less fluent in all things Latex. I've tried in many ways and couldn't find how to tweak it to apply a style to pandoc fenced divs. In the raw Latex file that it outputs, there's not even a command indicating that there was something there. It's just ignored.

I've searched a long time for this answer, and I can't find any clue. Thanks in advance.

    Welcome to TeX.se! I don't think this is a supported feature yet (if it ever will be). See github.com/jgm/pandoc/issues/5880 for some discussion. The recommended approach seems to be to use Lua filters.

    AFAIK you must use ::: {.special data-latex=""} and of course the "special" environment should have been already defined in the template preamble, the document class or some package, that I suspect that is not usable to export to another formats.

You need a lua filter to process the fenced div:

function Div(el)
  if el.classes[1] == "special" then
    -- insert element in front
      el.content, 1,
      pandoc.RawBlock("latex", "\\begin{Special}"))
    -- insert element at the back
      pandoc.RawBlock("latex", "\\end{Special}"))
  return el

This will transform the div to a latex environment:



Some special text, \emph{with markdown formatting.}


You mustn't forget do define the environment in your template:

    Thanks! If you didn't already know: You can output the AST with --to native to figure out how pandoc represents the elements internally
