The Birth of vi
lanc writes "Bill Joy, co-founder of Sun, tells the story of how he wrote the vi editor. The article at The Register delves into his motives, who instigated the project, and some of the quirks of leaving a 'gift to mankind'. From the piece: '9600 baud is faster than you can read. 1200 baud is way slower. So the editor was optimized so that you could edit and feel productive when it was painting slower than you could think. Now that computers are so much faster than you can think, nobody understands this anymore. The people doing Emacs were sitting in labs at MIT with what were essentially fibre-channel links to the host, in contemporary terms. They were working on a PDP-10, which was a huge machine by comparison, with infinitely fast screens. So they could have funny commands with the screen shimmering and all that, and meanwhile, I'm sitting at home in sort of World War II surplus housing at Berkeley with a modem and a terminal that can just barely get the cursor off the bottom line.'"
(I'm using Emacs, BTW.)
I think in vi. When editing, commands just happen like thoughts. They are so ingrained in my brain I don't even remember the actual key sequences. When a vi newbie asks, "how do you do XYZ in vi?," I have to stop and think hard, because I don't even know the commands any more.
Vi is the ultimate editor, for one main reason. It's a modal editor, so commands can be mnemonic. With editors like emacs, you're always having to hit ^X before commands, or with MS word you're always having to lift your hand off the keyboard to move the silly mouse around. With vi, you don't need a steenking mouse. Your hands never leave the keyboard. And commands make sense and don't require that you hit some yucky control sequence to initiate.
I love my vi.

I use vi everyday but i've long stopped recommending it to most people i introduce to linux.
it really doesn't seem worth steep learning curve for most people.
Do you recommend vi to all new *nix users now?
This is good history to remember. Those who weren't there find it hard to appreciate the tremendous leap forward of Unix Version 6 and ed on a PDP-11. We had been using teco on our PDP-10 and the cousin of ed that was on Multics, but we had been getting into PDP-11s for more and more things. Comparing ed on Unix with the line editors available on PDP-11 DOS/BATCH and that new-fangeled RT-11 thing was amazing. Along with all the other tools available on Unix, the PDP-11 went from a toy to a state-of-the-art (for then) development environment. We were mostly on DECwriters and TI-Silent 700s runing hardwired 1200 baud at work and 300 baud from home over the modems. We started to get VT-100s about the time vi was being released and it was again a great leap forward.
Thanks Bill Joy! I have used your work in the BSDs and Suns and all the followons over the years, but vi was a most important gift at an important time.
vi was a horror when I started using UNIX systems and I couldn't understand why anyone would want to use such a strange editor. So I went with emacs and was happy. But after a while (dunno how this happened) I went back to vi(m) and invested the necessary time to learn it. I took me about a year before I could say that I'm able to use it efficiently, so the learning curve is pretty heavy. But at the end I don't regret it at all, because I feel a lot more efficient with vi(m) than with any other editor. I couldn't live without it now.
Good tools are hard to master.
The article has definately triggered some nostalgic moments, but it's an article from September 2003 that reports on the content of an interview conducted in 1999. It isn't really news any longer.
I haven't found vi or emacs to be hard enough.
That why I port edlin to every box I work on.

I actually want that on a t-shirt. I would do it myself, but I don't think my stenciling skills are up to the task.
Modal editors are a bad idea, but the thing is, most people don't actually want an editor. Most of the time, they want an electronic typewriter. Entering text and editing text are two conceptually separate tasks, and this is why vi works as an exception to the rule 'modal user interfaces are bad.' Vi is really two separate applications; one for entering text, and one for editing text. Because you often want to do these in quick succession, it allows you to quickly switch between them.
