# Linting

We use automated tools, rather than human effort, to spot possible bugs or dubious structural choices, where possible. This is handled by three tools:

- Javascript is linted using [eslint].
- Rust is linted using [cargo check] and [clippy].

[eslint]: https://eslint.org/

[cargo check]: https://doc.rust-lang.org/cargo/commands/cargo-check.html

[clippy]: https://doc.rust-lang.org/cargo/commands/cargo-clippy.html

## Tools

- To check for detectable lints, run
  `tools/check-lint`. This should be run whenever making changes, and is part of the optional
  `git-hooks/pre-commit` hook script.

- To fix lints that have automatic fixes, run
  `tools/delint`.

You can also run the individual lint tools directly. The tool scripts listed above contain the specific commands needed.
