bacon is a background code checker.

It's designed for minimal interaction so that you can just let it run, alongside your editor, and be notified of warnings, errors, or test failures in your Rust code.

Documentation

The bacon website is a complete guide.

Below is only a short overview.

install

cargo install --locked bacon

Run this command too if you want to update bacon. Configuration has always been retro-compatible so you won't lose anything.

Some features are disabled by default. You may enable them with

cargo install --features "clipboard sound"

check the current project

bacon

That's how you'll usually launch bacon, because other jobs like test, clippy, doc, your own ones, are just a key away: You'll hit c to see Clippy warnings, t for the tests, d to open the documentation, etc.

check another project

bacon --path ../broot

or

bacon ../broot

check all targets (tests, examples, benches, etc)

bacon --job check-all

When there's no ambiguity, you may omit the --job part:

bacon check-all

run clippy instead of cargo check

bacon clippy

This will run against all targets like check-all does.

run tests

bacon test

or bacon nextest if you're a nextest user.

When there's a failure, hit f to restrict the job to the failing test. Hit esc to get back to all tests.

define your own jobs

First create a bacon.toml file by running

bacon --init

This file already contains some standard jobs. Add your own, for example

[jobs.check-win]
command = ["cargo", "check", "--target", "x86_64-pc-windows-gnu"]

or

[jobs.check-examples]
command = ["cargo", "check", "--examples"]
watch = ["examples"] # src is implicitly included

and run

bacon check-win

or

bacon check-examples

The bacon.toml file may evolve with the features and settings of your project and should be added to source control.

Optional features

Some bacon features can be disabled or enabled at compilation:

• "clipboard" - disabled by default : necessary for the copy-unstyled-output internal
• "sound" - disabled by default : necessary for the play-sound internal
