Earlier quoted context omitted.
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).
Previous comment was written on my phone and it decided to autocorrect Lua to Lue.
