[NTG-context] directlua question

[Hans van der Meer]

I am trying to extract something from a string with a \directlua call, the last word of a string in case:

\directlua{tex.print(string.match(“This is a string","%s%a$"))}

However, the %s%a are not working with the TeX-error “unfinished string near eof”. Obviously caused by the %’s.
How to get this working? \textpercent will not do, off course within Luacode.

Also I tried to no avail

\begingroup\catcode`\%=12\relax\directlua{tex.print(string.match(“This is a string","%s%a$"))}\endgroup

% = \letterpercent
$ = \letterdollar

You can also replace

\directlua{tex.print(...)}

with

\ctxlua{context(...)}

or

\cldcontext{...}
