Works for me. Do you have the Tree-sitter grammar installed? What does checkhealth rainbow-delimiters display?

[jay-babu]

==============================================================================
rainbow-delimiters: require("rainbow-delimiters.health").check()

- ERROR The healthcheck report for "rainbow-delimiters" plugin is empty.

Looks like the plugin did not install properly for you. Can you please try uninstalling and installing it again? If that does not work, can you please post the directory contents of your local copy? You can use the tree command to print a nice directory tree.

https://gist.github.com/jay-babu/787c7376f0b058f1ca51c26df4a5bc1d. I uninstalled and installed and the same error came up again

[HiPhish]

That's weird. Which version of Neovim are you running? Are you somehow lazy-loading this plugin?

[jay-babu]

NVIM v0.9.1
Build type: Release
LuaJIT 2.1.0-beta3

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/usr/share/nvim"

Run :checkhealth for more info

I was lazy loading, but just tried without it. the same problem

[jay-babu]

I am using the lazy plugin manager

[HiPhish]

Does the problem still persist on the current master? Are languages other
than Java affected? If you :edit the buffer again does it work then?

As for the health check, we can compare hash values. Here is the SHA-256 of my
file:

If yours differs then there is something wrong with your file.
