I’m afraid it doesn’t work.
\startluacode
userdata = userdata or {}
function userdata.numbersfname(name)
return string.match(name, "%d+")
end
\stopluacode
\defineexpandable[1]\numbersfname
{\cldcontext{userdata.numbersfname([==[#1]==])}}
\starttext
\numbersfname{abc123}
\numbersfname{\env{fname}}
\doifelse{\numbersfname{\env{fname}}}{123}{yes}{no}
\stoptext
Just curious about what the difference might be.
Many thanks for your help,
Pablo
