Hi Albert,
hi John,
hi all,

sorry for hijacking the thread.

I want to insert special context markup like

\startparagraph[intro]
...
\stopparagraph

via

::: intro :::
...
:::

The solution for latex was this:

There also was a short snippet from John MacFarlane:

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

function Div(el)
  if el.classes[1] == 'solution' then
    return { latex('\begin{solution}'), el.content, latex('\end{solution}') }
  end
end


How can I achieve this with context output. Simply changing the string "latex"
to "context" results in this error.

Error running filter filter.lua:
./filter.lua: createProcess: runInteractiveProcess: exec: invalid argument (Exec format error)
make: *** [Makefile:36: pdf] Fehler 83

TIA
