No syntax highlight in Neovim (LazyVim by Folke)

[Memnoc]

Hello 👋🏻

I have just today attempted to use this project as I am starting to work with slint. I can successfully install the treesitter and lsp via Mason and TSInstall slint respectively.

However, I get completely white text, no syntax highlighting, linting or formatting provided. I have then tried to manually override the config offered from LazyVim to no avail.

I have tested this on three different machines with Debian, Fedora, MacOS Sonoma respectively.

just to make sure, I have tested the same code on VSCode with the slint-extension and there I get all the features and functionalities.

Let me know if I can help this in any way - thank you!

Hi!

I should probably mark this repo as public archive as I haven't maintained it in a while. Slint manages their own version of the Grammer in their main repository under the editors folder.

If the nvim lsp points here it should probably be changed to the slint version

[Memnoc]

Hey! Thank you for your answer!

Do you think submitting a PR to treesitter asking them to point to the new resources would be helpful?

[jrmoulton]

I do think that would be a good idea. What do you think @hunger?

@jrmoulton: My last state was that you wanted to continue working on your version and maybe even eventually merge that work into the official slint repo. I did not want to interfeer, so I did not do anything wrt. tree-sitter in a while.

If you are archiving this repository, then pointing Mason/etc. to the tree-sitter in the Slint repo would make a lot of sense.

@jrmoulton @hunger any news on this? Do you want me to submit the PR to tree-sitter? Happy to help :)

Feel free to do the PR:-) Any help with tree-sitter is appreciated!

PR was not accepted - sorry lads

[Memnoc]

However for anyone reading, if you attach a file type manually with :set filetype=slint you do get syntax highlighting at least

That was not a PR, but invalid usage question. slint is supported by nvim-treesitter and highlight should work fine as the parser and query files exist. Looking at your specific issue what you can refer to is

• :help ftdetect
• :help vim.filetype.add()

[jrmoulton]

I have no issue with this issue being open. Just seems like there was some misunderstanding.

I opened an actual PR to point nvim treesitter to the official slint repo

[wookayin]

Sorry for my misunderstanding, the request the OP wanted is now going to be addressed by replacing with a new tree-sitter parser, as you already did.

[jrmoulton]

@wookayin no problem. I got taken for a ride for a bit too.

@Memnoc PR is short for pull request which refers to the merging of changes into a repository.

It is separate from an issue.

Thanks for taking initiative to help improve things!

[Memnoc]

@jrmoulton @wookayin thank you both and sorry for the misunderstanding.

For the record, I know and work with PR's daily, and yet I've misused the term here, causing confusion. My bad!

I'll make sure to look into the technical aspect of this issue as there some things I don't understand (clearly) but I appreciate the help nonetheless.

Thank you all 👍🏻

Ah, progress, just in time when I just did something on our tree-sitter code :-)

Thanks @Memnoc and @jrmoulton for doing all this.

[Memnoc]

Hey @hunger I saw your PR was merge days ago, congrats and thank you for all the hard work! I am still clearly missing something I think because even after updating the LSP via Mason and reinstalling the Tresitter part I still get no highlighting just like before.

I apologise in advance if I am missing some basic neovim 101 here, but based on basically any other language I use, when I install LSP and Treesitter I get code highlights and completion and all the rest, but it does not seem to be the case here.

[jrmoulton]

@Memnoc can you run a :checkhealth and check in the tree sitter section if slint is listed there and has a checkmark for H (highlights)

[Memnoc]

@jrmoulton sure thing, it checks out all the boxes

- slint ✓ ✓ ✓ ✓ ✓

If I do a filetype=slint on the buffer, I do get highlighting but not formatting or autocompletion, and a LspInfo on the buffer shows

Seems to me the issue is that .slint is not detected as filetype, but I have no idea why is that

[jrmoulton]

You need to configure the filetype for slint in your configs. Neovim doesn't know about it natively. That will fix this issue with the highlighting.

The lsp issue is unrelated to the tree-sitter config and nothing with the tree-sitter highlighting affects it. You'll need to check the lsp configs (tree-sitter is also not involved with formatting or autocompletion. That is also the lsp)
