What languages are supported?

[shobrook]

Hi,

Just need some clarification. The tree-sitter-stack-graphs crate appears to only support four languages. The stack-graphs crate claims to work for any arbitrary programming language. I'm wondering, if I want to use this with more languages, what do I need to do? Which crate should I use? If I use the tree-sitter crate, do I need to supply a grammar for that language? What about the stack-graphs crate?

Thank you!

Thanks for the question. The setup for stack graphs is indeed similar to tree sitter. While tree-sitter is not specific to a language, a grammar is needed to support any particular language. Similarly, stack-graphs and tree-sitter-stack-graphs are not specific to any language, but a set of rules is needed to be able to generate stack graphs for any particular language. For tree-sitter-stack-graphs, these rules are written in TSG (e.g., for TypeScript) and we have done that for four languages so far. To support other languages, someone has to write such a TSG file for that particular language. (Since tree-sitter-stack-graphs is using tree-sitter, this assumes a tree-sitter grammar already exists.)

Hi
In Typescript stack-graphs.tsg i see rules support tsx too.
But when i try to index tsx file it does nothing.
When i try to parse like tree-sitter-stack-graphs-typescript parse Dropdown.tsx, i'm getting Error: No stack graph language found
Please help me.

Thank you!

Hello,
Has anyone enabled stackgraph for C programs? or is any one working and need collaboration. I can chime in.
please advise.
Thank you

@hendrikvanantwerpen is the TSG for Typescript written by hand, or can it be generated from the typescript grammar (and if so, how)?

It was written by hand (heroically) by @hendrikvanantwerpen

@hendrikvanantwerpen How can I start writing a TSG grammar? I want to create a grammar for C#, just to practice and understand this large project. I look at existing grammars and it seems overwhelming. I don't know where to start to understand the code.

• Should I start writing my grammar in the same order you wrote the TypeScript one?
• Do you have any debugging techniques to test that your grammar is working, something more visual?
• Any cookbooks?
