[NTG-context] \startluacode and macro names with underscores

2012-09-04 Thread Marco Patzer 
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.

Use this in your Lua code:

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