in thread Find Prefix if regex didn't match
Thanks for your fast answer!
some good aproaches but no hit...
pos() doesn't work because if the string only contains a prefix of the given expression (what will be the hot case I'm looking for) I will get undef and not the position I need or do I overlook sth. here?
My "window" can become as large as it likes, doesn't matter, but I have to ensure that no matching will be overseen, that's quite important! It's just to make the searching faster and if I know that the first n characters can be thrown away because they can never be part of a matching would do the job.
Any alternative suggestion?
