Hello ConTeXist.
Sorry for the beginner question, more for Lua(TeX) experts.
Can somehow be achieved that the parameter of TeX macro get to
luafunction unchanged?
In the debug.txt file is the result obtained.
Thanx Jaroslav
\startluacode
debug=io.open("debug.txt","w+")
function testfun(param)
debug:write(param)
-- tex.print(param)
end
\stopluacode
\def\testmac#1{\directlua{testfun('#1')}}
\starttext
$\frac{x_\alpha+y_\beta}{z_\gamma}$
\testmac{\frac{x_\alpha+y_\beta}{z_\gamma}}
\stoptext

Use the thirddata or userdata namespace for for functions.

\def\testmac#1{\ctxlua{testfun(\!!bs\detokenize{#1}\!!es)}}

Thanx Wolfgang.
In ConTeXt this solution works well.
Exist any similar solution in pure LuaTeX? I need solve one problem in
pure LuaTeX.
But solutions in Context I will also throw - thanx.
