Re^2: Dictionary filter regex

I second your approach to break up the logic into 3 regexes, but

> Mushing this into a single regular expression is possible, by using [^sh] instead of dot

Do you mean /s[^sh]*h/i ?

I doubt this, you would also need to check all characters before and after the match

/^ [^sh]* s [^sh]* h [^sh]* $/xi *

Otherwise something like "h--<s--h>--s" should match in the middle. (Untested)

I think this demonstrates well why stuffing all logic into one regex is not always a good idea, particularly inversion isn't trivial.

Yes - my post would have been much clearer had I also included the anchors and the (then explicit) `.*` before and after the matches. Thank you for pointing this out and making it explicit!	[reply] [d/l]
