This [1] is an attempt to do just that. I haven't really looked at the source, but from what I gather it is a way to combine keymaps, actions, parsers, and syntax grammars however you like. There's also a vi mode (don't know how complete) and I think the modular approach they've taken is the way to go.

Also, it is written in Haskell.

urgh; I feel that the last thing we need is to couple our editors even more strongly to the flavors of the month (and 500mb+ of dependencies). I wish these things were more ecumenical...

How is Haskell a flavor of the month?

For the record, the first commit to the Yi project was 8 years ago. This isn't some flash in the pan project.

We are speaking in a context set by vi/vim (remember, that was the jumping off point for promoting yi here).

If you cannot think of at least one language which is older and a better common denominator than Haskell (both at the binary level and at the interface presented to programmers)... I don't know what to say.

What actual reason do I have for switching from vim to yi? Just because it's written in Haskell and that obviously makes it better, or what?

[eridius]

I... have absolutely no idea what you're trying to say. It's not worth ever using a language if there's an older one around? Are you saying you don't want to switch editors unless the new one is written in FORTRAN?

[pka]

Yes, we should write our editors in assembler.

it's not that haskell is bloated...
