Hi,
the luacode environment chokes on macro names with underscores.
Example:
\starttext
\unprotect
\def\number_two{two}
\startluacode
   userdata = userdata or { }
   function userdata.number_one() context("one") end
-- works
   userdata.number_one()
-- fails
   -- context.number_two()
-- workaround
   tex.print("\\number_two")
\stopluacode
\protect
\stoptext
Why is that and what can be done to access underscored macros in the
usual way? I guess it's some catcode change from the function that
prints into the TeX stream.
\starttext

\unprotect
     \def\number_two{two}
\protect

\startluacode
     userdata = userdata or { }
     function userdata.number_one() context("one") end

     userdata.number_one()

     context.unprotect()
     context.number_two()
     context.protect()

     context.pushcatcodes("prt")
     context.number_two()
     context.popcatcodes()

\stopluacode

\stoptext
