[NTG-context] Re: You can't use '\prevdepth' in restricted horizontal mode

3 Jan 2025

      Dear Dalyoung,

I am not sure what the issue is; but as a workaround it seems that using
\ctxlua works:

___________________________________________________
\starttext

\startluacode
  function makeHead(a)
    local n = #a

    context.HL()
    for i = 1, n  do
      context.NC() context(a[i])
    end
    context.NC()context.AR()
    context.HL()
  end
\stopluacode

\starttabulate[|mcw(1cm)|mcw(1cm)|mcw(1cm)|mcw(1cm)|]
    \ctxlua{local a = {"x","y","z","(x\\to y)"}; makeHead(a)}
\stoptabulate

\stoptext
___________________________________________________

Cheers,
Florent

Dear all,
I got the error "You can't use '\prevdepth' in restricted horizontal mode”
when I compile the following code.
If I remove “\starttabulete…  \stoptabulate”, then no errors, but the out
put is not the form of table.
How can I fix this error?
Thank you.
Best regards,
Dalyoung

\stopluacode

\startluacode
local a = {"x","y","z","(x\\to y)"}
