Supported Languages
Since we're based on tree-sitter, we can support all the languages that tree-sitter supports.
Presently, however, we use the wonderful go-tree-sitter by Maxim Sukharev behind the scenes, which gives us first-class support for the following languages:
| Language | Identifier |
|---|---|
| Bash | bash, sh |
| C# | csharp, cs |
| CSS | css, css3 |
| Dockerfile | docker, dockerfile |
| Elixir | elixir |
| Elm | elm |
| Go | go |
| Groovy | groovy |
| HCL | hcl, tf |
| HTML | html |
| Java | java |
| JavaScript | javascript, js, jsx |
| Kotlin | kotlin, kt |
| Lua | lua |
| OCaml | ocaml, ml |
| PHP | php |
| Python | py, python |
| Ruby | rb, ruby |
| Rust | rust, rs |
| Scala | scala |
| SQL | sql |
| Swift | swift |
| TypeScript | typescript, ts, tsx |
In the checker YAML file, you can specify the language you want to run the checker on by setting the language field, which should be one of the identifiers listed above.
NOTE
You can write checkers for all the languages listed above using either the YAML or the Go interface. Advanced features like imports and scope resolution, cross-file analysis are only available in the Go interface and only for a subset of languages at the moment — Python, and JavaScript.
