Do we have support for ruby?

[Bennet-Sunder]

I do not see a tsg file for ruby which means it's not supported I believe. However, I do see a crate here https://crates.io/crates/tree-sitter-stack-graphs-ruby which unfortunately doesn't install correctly.

I get the below error. when doing

cargo install --features cli tree-sitter-stack-graphs-ruby

Some initial work was done on Ruby support. You can find it in this PR: #270. But there has been no work beyond that.

[Bennet-Sunder]

if ruby support is not present in stack-graph, I'm guessing ruby repo's in github doesn't support precise navigation. So how does code navigation for ruby repos work in github if I may ask.

[hendrikvanantwerpen]

That's correct. Navigation for languages that don't have stack graph definitions is based on tree-sitter tags queries, as described here.

[Bennet-Sunder]

Thank you for the link, it's from the linked page how I discovered stack graph initially.

One final question, for search based code navigation which relies on tags generated via tree-sitter do you have an open source implementation of the same.

My use case I want to parse all the files in my repo via tree-sitter, generate tags via tree sitter and keep doing this for all the files in the repo. Later I want to run queries like find me references to a particular method etc for which the tags based implementation similar to stack-graph would be helpful if it's open source.

[hendrikvanantwerpen]

If there is such a tool it would be part of tree-sitter (similarly to how there's a highlighting command), but I haven't seen it, so probably not.
