killersheep VS nvim-cursorword

We all know that the real must-have plugin is vim/killersheep.

I guess that I sort of did actually answer your question: there are plugins that work on Neovim but not on Vim, but the only plugin I found that worked on Vim but not on Neovim is vim/killersheep, so you get more plugins at no cost.

I'm looking for games (snakes etc) that can be played inside vim/nvim but I haven't find good ones. killersheep can only be played in Vim, vim-snake doesn't work that fine ...

You can play the killer sheep by the grand master. :KillKillKill!

Try nvim-cursorword

Ok, my guess is that you are using RRethy/vim-illuminate, xiyaowong/nvim-cursorword, or mini.cursorword. All of them use underline as default highlighting for word under cursor. And that you tried ellisonleao/gruvbox.nvim variant of Gruvbox, which doesn't explicitly support none of them.

Finally, I think this should be solved upstream (probably LSP / the author of this API) instead. And I did find an alternative that can highlight the cursor word immediately, xiyaowong/nvim-cursorword, the only problem is that it is completely NOT LSP-related, no usage of treesitter (so hovering on the Lua function won't highlight its end). But who cares? If a feature cannot provide a good UX, it is f**king useless IMOO.

I was sleeping. Did you mean this one? [xiyaowong/nvim-cursorword](https://github.com/xiyaowong/nvim-cursorword)
