I was just rolling my own little thread about gsub ;]
and trying to fix my stupid regexen when
I came up with the perfect solution to replace the last occurence of a
pattern (if it is simple, thus not of any interest to the OP of the OT).
string.reverse.sub("<","").reverse is fast
string.sub(Regexp.new("<(?=[^<]*$)", Regexp::MULTILINE), “”)
is almost three times as fast (to my surprise), only that it does not
if there are newlines in the string, they match $.
Is there a way to anchor on the end of the string in multiline strings.
Just didn’t find it.
Ty in advance
