Precious is a code quality tool that lets you run all of your linters and tidiers with a single command.

It's features include: * One file, `precious.toml`, defines all of your linter and tidier commands, as well as what files they operate on. * Respects VCS ignore files and allows global and per-command excludes. * Language-agnostic, and works the same way with single- or multi-language projects. * Easy integration with commit hooks and CI systems. * Commands are executed in parallel by default, with one process per CPU. * Commands can be grouped with labels, for example to just run a subset of commands for commit hooks and all commands in CI.
