Hi Pablo,
unfortunately, that it is not possible:

\starttext \startTEXpage[pagestate=start, offset=1em] \startluacode local pat = (lpeg.Cmt(lpeg.P("this") + lpeg.P("that"), function(str,_,s) context(s) return #str end) + lpeg.P(1))^1 lpeg.match(pat,"how about this being that") local pat = (lpeg.Cmt(lpeg.oneof({ "this", "that" }), function(str,_,s) context(s) return #str end) + lpeg.P(1))^1 lpeg.match(pat,"how about this being that") \stopluacode \stopTEXpage \stoptext

Dear list,
I have the following sample:
\starttext \startTEXpage[pagestate=start, offset=1em] \startluacode local str = "this is that" context(str:match("(this|these)")) \stopluacode \stopTEXpage \stoptext
In short, I would like to know whether it is possible to have the regular expression (this|these) as a Lua pattern.
I mean, I need complete strings and I haven’t found the way to do it.
Many thanks for your help,
