I'm having trouble finding a pattern that works for finding an
unescaped quote in a string. So:
[[\']] should not match
[[']] should match
I can get it to work with '([^%\\]")' , except at the beginning of the string.
You could put a dummy character at the beginning of the string ...
My suggestion:
 local function qfind( s )
 local ok, a, b = string.match( " "..s, "[^\\](\\*)%1()[\"']()" )
 if ok then
 return a-1, b-1
 end
 return nil
 end
(But if you write an extra function for matching, you could as well try the two different patterns and save the temporary string ...)
