Re: How to make my latex environment accessible from markdown via short-code?

[Bastien DUMONT <bastien.dumont-VwIFZPTo/vqsTnJN9+BGXg@public.gmane.org>]

To complement Denis' answer, your Markdown chunks in "hint.lua" are handled like strings because you created them as Str objects. What you want is to return a CodeBlock (https://pandoc.org/lua-filters.html#pandoc.codeblock), e.g. `pandoc.CodeBlock("latex", "\\begin{guidehint}")`.

More generally, Pandoc has already parsed the input file when it applies filters. Filters manipulate objects in the internal representation of the document and should return such objects. In exceptional cases where you really need to parse a Markdown string inside a filter, use pandoc.read.
