I am converting markdown to pdf via latex using my own template.

In the template I have defined a new environment called 'hint' that is like a call-out.

This works:

The Lorem text appears in the callout-environment.

I want to make the environment accessible more conveniently via a short-code.

I have created a new lua-filter, 'hint.lua' that I successfully include:

return {
  {
    Str = function (elem)
      if elem.text == "{{hint_end}}" then
        return pandoc.Str("```{=latex}\n\\end{guidehint}\n```\n")
      elseif elem.text == "{{hint_begin}}" then
        return pandoc.Str "```{=latex}\\begin{guidehint}```"
      else
        return elem
      end
    end,
  }
}

But when I use it, the macro-text will be included literally:

{{hint_begin}}
Neque porro quisquam est,
{{hint_end}}

The code is not interpreted to end up being proper Latex, but it's escaped somehow to become a string literal.

Thus my output looks like this:

“‘{=latex}\begin{hint}“‘ Neque porro quisquam est, qui dolorem ipsum, quia dolor sit, amet, consectetur,
adipisci velit “‘{=latex} \end{hint} “‘

How do I make the short-code to get access to my own environments?

PS. If there are different apporaches, that'll be nice as well.

Thanks
