Right, good point - same in vi and vim (the editor). > > So perhaps the underlying regex parser ignores "/" characters at the > start/end of the regex unless they're quoted? Maybe, but I couldn't find any hint in the docs. > Is it used to refer to groups in text replacement? Sometimes that's a dollar > sign, sometimes a slash, but I thought it was a backslash Good point , but - IIRC, vim, at least, uses backslash for that, e.g., \1 ,\2, etc.; - furthermore, NSRegularExpression does not do any text replacement by itself, as far as I can see? Oh well, right now , I just don't escape any / , and it seems to work just fine. Best regards, Gabriel
