In the Python universe ruff handles code formatting and linting. Is there anything in Julia that I could call like `Linter.lint(".")`?

For formatting, you can check out Runic.jl, which is actually written in ~~Rust~~ Julia, or JuliaFormatter.jl. The linting story is less satisfying, the closest we have at the moment is JET.jl.

Runic.jl is written in Julia

Oops, I actually had Rust in mind because it’s so blazing fast 🤣

JET.jl is no linter, or maybe just a very small part of it. There are no rules like unused variables or so.
In principle there would be the linter that is in the VSCode extension. I don’t know how good that one is, it certainly has no convenient entry point.

I’ve come across [GitHub - RelationalAI-oss/ReLint.jl: Linter for the Julia programming language](https://github.com/RelationalAI-oss/ReLint.jl/) but haven’t used it myself

Looks promising

Aqua.jl does some things that could be called linting.

In case you’re not aware, the Julia VS Code extension does have [a linter](https://www.julia-vscode.org/docs/stable/userguide/linter/). I’m not sure if it’s enabled by default. To enable it, make sure that `julia.lint.run` is set to true. I also recommend turning on the linting for missing references, which is the most common kind of linting error that you will see.

Just out of curiosity, is it possible to run the VS Code linter from the command-line, e.g. in CI?

Since it uses StaticLint.jl, I guess not [Docs? · Issue #14 · julia-vscode/StaticLint.jl · GitHub](https://github.com/julia-vscode/StaticLint.jl/issues/14)

There is an [upcoming JuliaCon talk about ReLint](https://pretalx.com/juliacon-2025/talk/RCUTNF/) by the way!

There is my new package Fatou! [https://github.com/jolars/fatou](https://github.com/jolars/fatou). It is not just a formatter and linter but also a language server (exactly like ruff). Still very early in development, but please consider giving it a go 🙂
