Which differences of vim relative to vi > are based on POSIX? One particular annoyance I just came across while trying to edit this message with VIM is that historical VI beeps when you're at the last word, while VIM insists on going to the last char. The rest are the same type of thing - where traditional VI does the so-called "logical" thing, but POSIX decides to try interpreting what you may've wanted to do, and acts based on that. Call me a control freak, but I don't like the idea of a smart editor; I want my editor to be a small piece of software that does exactly what I tell it to, not what it thinks I want it to. (Translation: as far as text editors go, AI sucks and elvis rocks.) I'm on an oldish version of VIM here, so I don't remember all the other ones off-hand. I just remember complaining about some annoyances a couple of years ago, and having the guy point to parts of the IEEE spec. I decided to read the rest with an open VIM handy and found a few other instances where the annoying VIM behavior was actually correct according to POSIX. (To be fair, virtually all of them had weird settings in VIM to disable the POSIX behavior, but since I wasn't on UTF yet I decided to just return to elvis and call it a day. I only use VIM now occasionally, mostly to help people who're having trouble getting their entity macros working properly (elvis' entities aren't exactly VIM-compatible in general) and occasionally to fix a UTF file that I screwed up while editing with elvis.) > Offhand, the only interesting POSIX-based vi behavior that I recall is the > support for character classes in regular expressions. That's one of the few advantages of POSIX compliance ;-P - Dave -- Uncle Cosmo, why do they call this a word processor? It's simple, Skyler. You've seen what food processors do to food, right?
