How on earth can it be weird that a vim extension is written in vimscript?!

Well imagine a Java extension being written in Javascript...

Don't have to imagine, it's been a thing since Java 8.

Sunsetted in Java 14. Now it’s Graal.

It's rad man, someone should do this.

Vim is basically dead. Most new plugins are written in Lue (for Neovim). I don’t like Lue much but it’s 1000x better than vim script. I occasionally tweak my Neovim plugins but don’t bother with those written in Vimscript.

1. Vim is extremely alive

2. “Lue” is actually Lua

3. It’s very possible to use both Vimscript and Lua in the same Neovim setup, so transition (or don’t) at your leisure.

4. New plugins tend to be written in Lua (for Neovim).

Yes, new plugins are written in Lua, and this one wasn't. That is what is too bad.

Previous comment was written on my phone and it decided to autocorrect Lua to Lue.

There are far more vim users in the world than you realize. Every time I’m on ssh, I’m on vim. So daily, for the last 30 years.
