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
```

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

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
