The following MWE gives an error with LMTX 2020.09.05
\usemodule[vim]
\definevimtyping[MATLABCODE][syntax=matlab]
\starttext
\startMATLABCODE
saveas(gcf(), "output/same-sigma.png")
\stopMATLABCODE
\stoptext
The error message is:
callback error: ...metatex/texmf-context/tex/context/base/mkiv/lang-ini.lua:509: bad argument #1 to 'prehyphenchar' (luatex.lang expected, got no value)
stack traceback:

Any idea what is going on?
Thanks,

You have to add \resetbreakpoints to the vim/filter module.

Thanks. I had:
\doifnotinset{\v!hyphenated}{\externalfilterparameter\c!option}
{\language\minusone}%
which I changed to
\doifnotinset{\v!hyphenated}{\externalfilterparameter\c!option}
{\language\minusone
\resetbreakpoints}%
and this fixed the error.
Thanks,
Aditya

Don't use the \language hack, the official and supported commands are
\nohypens and \dohyphens or when you need a interface for it use
\usehyphensparameter\...parameter
which allows
\setup...[hyphens=yes|no]

This is a leftover from the old days. Thank for the suggestion on how to fix this. I'll play around a bit and perhaps add the option `hyphens=yes|no` instead of the current `option=hyphenated`.

the latest lmtx should be ok (predefines language zero)
but wolfgangs suggestions are the ones to follow ... language=0 is a
hack, just as is setting left/right hyphenmin so we now have a proper
disabler (in luametatex/lmtx that is; luatex/mkiv should not be affected)
