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
