vim9 VS vim9jit

According to some of the original benchmarks Bram and others did, yes, by a small margin.

I can't comment on the language, but Bram wrote up motivations in brammool/vim9.

I don't see why you would write a plugin in VimL in 2021. I mean even VimL's author decided to just create a new language — vim9 script — instead of fixing this one [1].

With neovim rpc you can write glorious plugins in TypeScript and Python such as coc.nvim [2].

Other than that, I'm inspired by amount of work you put in the project.

I think its cryptic reputation comes form the use of normal mode commands and regex within scripts. There certainly are warts, like the user's 'ignorecase' setting permeating to many places in the runtime. Which I'd love to see fixed and whilst may also represent a breaking change for some scripts would be far more easily adoptable.

That's not happening any time soon, but there's this project by one of Neovim's contributers that transpiles Vim9 script into Lua.

Probably feasible with https://github.com/tjdevries/vim9jit actually

There's https://github.com/tjdevries/vim9jit. It has reportedly been used to port Vim9script runtime files to Neovim.

Neovim is going to use a transpiler that covers vim9script code to lua code using the nvim api in the future (https://github.com/tjdevries/vim9jit)

I didn’t watch the streams because I wasn’t totally sure what he was even doing, but maybe this will take some of it off your hands: https://github.com/tjdevries/vim9jit

It could (rightly) be argued that neovim could just merge in vim9script, but I think this probably isn't the best more. I'm personally more in favor of getting a vim9 cross-compiler working, that way there's an easy way to support both. But that's my ignorant two cents on the matter.

A core contributor to Neovim is toying with a Vim9Script to Lua convertor.

That's not necessarily true.

Core maintainer of the Neovim Tjdevries is working on a compatibility layer that would allow vim9 to not only run in Neovim, but likely faster.

My understanding was the neovim folks decided this wasn't work the hassle. TJ already has https://github.com/tjdevries/vim9jit, which transpiles vim9scripts to lua, and that is much more likely the way things will go.
