tree-sitter: Add the .slint UI language

[flukejones]

• Added an entry to CHANGELOG.md if this change could be valuable to users

This is paired with lapce/tree-sitter-grammars#28

I don't know if this is the correct method to go about this. There does not appear o be much documentation about adding languages.

Slint is a UI made with rust https://slint.dev/

We don't accept more grammars built-in to lapce

[panekj]

The grammar is not open source so it can't be added

[aurindam]

@panekj Its licensed under GPLv3.

[panekj]

@aurindam it is absolutely not, there is a directory with 3 different licences without any guidance what is supposed to be used (probably same how slint is licenced but I'm not going to be guessing)

Cargo.toml, pyproject.toml and etc. specify MIT, which means that no one bothered to actually licence that repository properly

[aurindam]

@panekj Would a README in that folder clarifying that its triple licensed (like Slint) be sufficient?

[panekj]

@aurindam yes, if it also includes a note on how the parser code is licenced, if grammar.js is to be triple-licenced like slint according to the SPDX in file with parser code as MIT or the generated bindings/parser code should also be triple-licenced together with grammar.js

@panekj: I just pushed a PR re-licensing the gammar.js to MIT (in the mono repo) and will put a copy of MIT into LICENSE.md in that tree-sitter-slint repo once that gets visible there. I hope that makes everything clearer.

Thanks for raising this, licensing is always tricky to get right and feedback like this is really helpful.

@panekj: I updated slint-ui/tree-sitter-slint. It's README.md states that we only hold copyright to grammar.js, which contains MIT now in its SPDX identifier. LICENSES contains MIT.txt only now and the README points to that file. I hope this makes it crystal clear that our tree-sitter parser is open source software.

[panekj]

@hunger Thank you, it definitely works for me and assures the status of grammar "legality" :)

[hunger]

Great! Anything else I can do to help from our side?

[panekj]

Nope (unless you're interested in preparing queries for Lapce), I'm in progress of restructuring (and adding much more) grammars here: https://github.com/lapce/tree-sitter-grammars/tree/be-less-stupid
Languages/queries are updated here: #3279 (partially, will be cherry-picked to master once ready) but we're planning on moving queries to the repo with grammars

Overall its just time consuming (and tedious) to prepare logic for updating and distributing grammars.

[flukejones]

@panekj will you be managing this from now, or shall I update and reopen the PR?

[panekj]

@panekj will you be managing this from now, or shall I update and reopen the PR?

If you remove the tree-sitter grammar (just add the Syntax definition and slint LSP id in proxy buffer) I'll merge it

[flukejones]

@panekj should be good to reopen and merge now I think

@panekj: Sorry, I am not into GUI IDEs anymore. Been there, done that...
