Subject: Weird error when using \startformula inside lua
Date: Fri, 10 Sep 2021 23:11:54 -0400 (EDT)	[thread overview]
Message-ID: <nycvar.YAK.7.78.908.2109102305430.1211317@nqv-guvaxcnq> (raw)

I sometimes define lua functions for showing out worked out calculations. The following minimal example shows that 

  context([[\startformula ... \stopformula]]) 

fails in LMTX with an error message:

tex error       > tex error on line 3 in file ./test.tex: Undefined control sequence \undefined 

MWE:

\startluacode
  thirddata = thirddata or {}

  local comment = [[
    This is a famous formula
    \startformula
      a^2 + b^2 = c^2
    \stopformula
  ]]

  function thirddata.explanation()
      context(comment)
  end

\stopluacode

\starttext
\ctxlua{thirddata.explanation()}
\stoptext

The actual use case is more complicated (where I use templates, so I don't want to convert everything to context.startformula() etc.). The example compiles with MkIV but not LMTX.

Any idea what is going on?

Thanks,
Aditya
