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.


% = \letterpercent
$ = \letterdollar

You can also replace

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

with

  \ctxlua{context(...)}

or

  \cldcontext{...}

\begingroup\catcode`\%=12\relax\directlua{tex.print(string.match(“This is a
