Opening the latest Neovim to various files (e.g. lua, fish, etc.) results in the following error, and disabling neodim fixes it.

Error in decoration provider treesitter/highlighter.line:

Maybe you should care about the version

[carmarfee]

I am having the same question:(

[futsuuu]

@carmarfee
Can you show me the error message and the output of nvim --version?

[carmarfee]

@futsuuu
nvim0.9.5
sorry，i don't know how to show the entire error message,but it shows the same error as the man

[carmarfee]

@futsuuu
okay,i have tried my best and it does bother me a lot ,it seems that i can't find where the function"highlighter:for_each_highlight_state" is, and is that the problem?

[futsuuu]

@carmarfee
This plugin requires Neovim v0.10.0. Please use nightly version.

[carmarfee]

@futsuuu
emm...,this was so annoying that i deleted your plugin,but now i'll think about downloading it back,anyway,thanks for your kindness!

[zbirenbaum]

Keep in mind this plugin was made back when LSP support for unused variables was nowhere near what it is now. This plugin is likely not super useful for most languages anymore due to semantic tokens and is probably due to be archived soon.

I'm happy to keep it around if you think that it still has a use case @futsuuu but figured I'd let my thoughts be known

[AlexSWall]

Neovim v0.10 hasn't even been released, so making it a dependency of neodim's master feels premature.

It's probably worth putting into the README the tag, commit, etc. to use for those on the latest released version (v0.9.5).

@futsuuu nvim0.9.5 sorry，i don't know how to show the entire error message,but it shows the same error as the man

@carmarfee
I had the same problem as you, and I just successfully solved it

Different from yours, my neovim version is 0.10.0. I found out that the reason why I had this bug was that my lazy pulled a non-latest version of neodim. So the problem is most likely caused by the version matching between neovim and neodim.

Considering that your neovim version is 0.9, I guess it is because you pulled the latest version of neodim that caused your problem. My suggestion is that you can delete ~/.local/share/nvim/site/lazy/neodim manually pull the old version of neodim

My neovim version is 0.10, I had the same problem:

[futsuuu]

@yinghaoyu Please update neodim.

[futsuuu]

@zbirenbaum Sorry for very slow response... Are there any ways to dim unused values using builtin lsp client?
