Using non-greedy quantifiers with substitute()

[Felix Thibault]

I'm having problems with a plugin and I've narrowed it down to one line. If I write:

echo substitute("#|\nmulti-line comment\n|#","#|.*|#","","g")

the substitution happens like expected. But if I use a non-greedy quantifier I get the original string unchanged

echo  substitute("#|\nmulti-line comment\n|#","#|.\{-}|#","","g")

You've used a double-quote string, which processes backslash characters, for the pattern. Either double the backslash, or use a single-quote string:

echo substitute("#|\nmulti-line comment\n|#",'#|.\{-}|#',"","g")

HTH, and regards,

Thank you so much- I had no idea about single quote strings.
