Re^9: Truncating after the last period

Huh? What are you talking about?

Since this is, to my memory, the first time anyone has suggested what you are suggesting is possible, I assumed that you had to be talking about the new 5.14 regex modifiers: a, d, l and u These modifiers, new in 5.14, affect which character-set semantics (Unicode, ASCII, etc.) are used, as described below in Character set modifiers."

Of course, if you would demonstrate rather than allude, it wouldn't be necessary for all us lesser beings to guess what you are alluding to with your pronouncements from on high.

\X [4] Match Unicode "eXtended grapheme cluster" Hm. So let me see if I have this right. Because the OP mentioned the word "characters" -- even though he didn't mention ~~unicode~~ (Oops. PST) Unicode -- you are saying that we can no longer use the regex metachar '.', because we don't know that it won't be Unicode, and we therefore run the risk of splitting an "eXtended grapheme cluster". Which in turn implies that we should never use the '.' metachar. Which of course ~~begs~~(PST) leads to the questions: Why have '.' if you must always use \X instead? Why not simply replace the '.' semantics with the \X semantics and have done with it. I suspect the reason is PST, but I'll keep an open mind.

Like I wrote before, "You just have to know it and use it." Perl's got it. Almost every other programming language doesn't.	[reply]
