I find it simpler to write macros where there is clean communicating between tex and lua. For example: [...] \define[1]\numbersfname {\cldcontext{userdata.numbersfname([==[#1]==])}} This is the first time I see that way of wrapping an argument.
In any case, I cannot compare to a number:
\startluacode userdata = userdata or {} function userdata.numbersfname(name) return string.match(name, "%d+") end \stopluacode
\define[1]\numbersfname {\cldcontext{userdata.numbersfname([==[#1]==])}}
Untested: \defineexpandable[1]\numbersfname {\cldcontext{userdata.numbersfname([==[#1]==])}} Wolfgang
