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

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

[Stefan Schroeder]

[-- Attachment #1.1: Type: text/plain, Size: 1823 bytes --]

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:
---
```{=latex}
\begin{hint}
```
Lorem ipsum dolor sit amet, 
```{=latex}
\end{hint}
```
---
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
Stefan

Just use divs for that:

::: hint
Whatever
:::

Now, you can use a filter like the one below (posted by BPJ at some point).

This will check each div whether it has one of the classes defined in ENV_CLASSES. If yes, it will insert an appropriate raw block.

```lua
ENV_CLASSES = { 'intro', 'question', 'solution', 'hint', 'definition', 'whatever'}

local function latex(s)
  return pandoc.RawBlock('latex', s)
end

local function get_env_class(elem)
if elem.classes then
  for i = 1, #elem.classes do
    for j = 1, #ENV_CLASSES do
      if elem.classes[i] == ENV_CLASSES[j] then return ENV_CLASSES[j] end
  end
end
else
  error('function has_class used on an element of type ' ..
        elem.t .. ' that cannot have classes.') end end

function Div(el)
  local env_class = get_env_class(el) -- nil if there is none
  if env_class then -- false if env_class is nil
    return { latex('\\begin{'.. env_class..'}'), el, latex('\\end{'.. env_class..'}') }
  end
end

function Span(el)
                if el.classes[1] == 'speaker' then
                               return pandoc.RawInline('latex', '\\speaker{'..el.content..'}')
                end
end
```

Whoa! That was quick. Thanks, Denis. I'll try it out and post my result 
here.

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

[Bastien DUMONT]

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.

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

[denis.maier-NSENcxR/0n0]

Or, maybe even a RawBlock? Like in that function:
local function latex(s)
  return pandoc.RawBlock('latex', s)
end
