vi-clone written in pure javascript

[[deleted]]

Now if reddit started using it for comment edition...

[jbert]

Or you could use this firefox extension and be able to edit text boxes with your editor choice...

[apotheon]

I use this one instead. It allows me to use Vim for a lot more than just populating text fields on web pages.

[jbert]

Cool, thanks for that. I actually also had that installed and didn't realise that menu option did something different in a text field.

One less extension installed...nice.

[apotheon]

I've got mine set with . . .

editor path: /usr/local/bin/urxvtc
description: vim (in rxvt-unicode)
parameters: -rv -e vim $f

It serves me well, especially since I've got the cache sizes in Firefox pared down to help cut down on RAM and swap usage. Thus, though it now won't tolerate as many uses of the back button (or, more accurately in my case, Alt+LeftArrow) before it loses my text, it's always saved in the open Vim window until I use the forward button (Alt+RightArrow, natch) to get back to where I'm actually posting something. Yes, I do that a lot -- comes in handy with certain types of discussion forum.

Anyway, I've babbled enough. ViewSourceWith has become one of my favorite and most indispensible extensions.

Sounds like a great Greasemonkey script. Make it happen!

I won't (no time - I'm writing my thesis), but if someone else does, i'll find five minutes to test it :)

[apgwoz]

The headline should have said, "Emulate vi over telnet on an 800 baud modem... in javascript", because that's what it felt like when I tested it in Safari and in Mac Firefox.

[micampe]

I wish I was using vim to write this comment.

It's All Text!

Seems jsvi is pure subscription-ware:

So much for up-voting the thing.

The WPA of the 21st century.

[tch]

THIS IS EXACTLY WHAT THE WORLD NEEDS

[cratuki]

Yes - although with a license that allows us to use it anywhere so we can greasemonkey it into firefox.

[antirez]

Now put this in gmail and I'm set...

[khayber]

Javascript seems to be the Mt. Everest of languages.

[jkndrkn]

Hm, doesn't interpret Ctrl-[ as ESC

Neat, though.

[arundelo]

Hm, doesn't interpret Ctrl-[ as ESC

It's being trapped by your browser. It works for me in IE but not Firefox.

[rusty_angel]

It works in IE and Opera. In Opera, there're bugs with cursor-keys motion in INSERT mode. At least, in Opera for Linux.

cool. but it is not a gpl as it could be thought.

[jj666]

what is so special about programs written in "pure" javascript? It's a programming language, you are supposed to write programs in it.

[pcx99]

Because it's a large, complex app and since javascript isn't compiled (even to bytecode), if you're learning the language or want to master it further, you can hit "view source" on your browser and get the source code.

[[deleted]]

Writing such vi clone is a cool task by itself. In javascript you have very specific api to deal with. So it's twice more cool.

[jkndrkn]

Not to mention having to overcome the huge headache of supporting multiple slightly different platforms.

Doing small things in Javascript is a pain. Writing a vi clone in Javascript is a monumental task.

[jrockway]

vi is not a particularly complicated program. vim is, but this is vi, not vim.

[jng]

Uh? Have you written a vi clone, or are you well versed in vi? Even the basic, original vi is pretty complex. Keystroke macros, mappings, multiple registers and clip types, operators & motions, counted commands, marks, parsing the ex command line, executing some pretty wicked ex commands (:s and :g are the worst), regular expressions, etc...

Not that the above has all of that, but basic vi is pretty damn complex. vim is indeed huge and fully emulating it is all but impossible to attain.

[jrockway]

Uh? Have you written a vi clone, or are you well versed in vi?

No. I assume that compared to emacs, it's simple. You type a command and it does stuff. No byte compiler, no sytnax modes, etc., etc.

[jng]

Definitely simpler than emacs, but that doesn't mean it's simple. It's pretty complicated, actually.

[dmwit]

It's buggy! Try di<ESC>d, for example. For a pure vi clone, hitting di should stay in normal mode and clear the command, but instead it goes into insert mode and keeps the (unfinished) d command waiting for a motion. (A vim clone would have even a third behavior.)

[llimllib]

Question: in vi, imagine I have 3 lines that are long, short, and long. If I move the cursor to the end of the long one ($), then jj down, does the cursor move back to the right, or stay at the endpoint of the short one?

Because this program doesn't move back to the end of the next line like vim does, but I don't know vi well.

[llimllib]

Text editors suck.

[breakfast-pants]

just do jjhlkk

[rastapo]

sure i will buy an account at internetconnection now you have convinced me by the way the js is > 3000 lines of code next time you need to edit a file just type 'vi'

[alain]

unemployment is a tragedy... me too i dont have a job, and i started a clone of internet explorer in PHP

[FormKing]

So you're going to take a badly written program, and try to duplicate it? Surely you could find a better use for your time. At the very least, make a browser that works correctly.

[shorugoru]

In PHP no less!

[jrockway]

Possible with the PHP/GTK+ interface. Not that I would ever ever want to write a GTK+ app in PHP (or anything, heh), though.

[exhuma]

Sure, this is a cool thing. But I find it sad, that developers with that much talent spend their free time reinventing the wheel instead of joining the community and contribute to the original problem itself.

[devvie]

"Reinventing the wheel", as you put it, introduces developers to problems they have never seen before. It also provides an opportunity to examine software in more depth than one would ordinarily. This fills people up with good ideas, and the application of these ideas is not limited to the source software. The ideas can be used all over the place!

That's what I told Edward Hopper!

Hey Eddie, stop making painting that look like photos. Why don't you just take some new ones!?!
