in reply to finding longest common substring

It seems I was a bit hasty in posting this question, and probably should have done a little more research first. gmax has pointed out Longest Common Substring, and etcshadow has pointed out Algorithm::Diff (which I have seen before, and is undoubtedly the reason the phrase "longest common substring" was floating around in my brain to begin with). Also, I updated my node mentioning japhy's Longest common substring, but apparently the update got eaten. (Is it just my imagination, or didn't we recently gain the ability to update root nodes?)

While Algorithm::Diff doesn't do exactly the same thing I am doing, it would have probably been useful at least. Sorry for wasting any time, and many thanks for the replies that did come! :-)

    It's not a waste of time (at least, I don't think it is). Personally, I think it's interesting that diff is based on LCS, and there are probably a lot of people who don't know that/might think it's interesting, too.

    Maybe this is more of a meditation, but I don't really consider it to be horribly obnoxious to ask a question that might be answerable via documentation search. Espescially when you consider how frequently people post ludicrously simple questions like "how do I write a regexp that does this: ...?" The other monks don't jump on those folks' cases, with "perldoc perlre... RTFM!" I don't understand why some of them are upset when someone asks a far more intelligent and informed question that might be answered by doc-diving.

    The truth of the matter is that doc-diving is often very difficult for finding where to start. You tend to run into the all-to-frequent problem of "I can find out what $module does, but I can't find which module does $thing".

    Anyway, don't appologize, it was a perfectly reasonable question. I (and the other folks) were just pointing you towards resources that might help in your search for more info.
