Pants v2: Fast, consistent builds for Python and more

Welcome to the Pants v2 documentation hub!

Pants v2 is a fast, scalable build system for growing codebases. It's currently focused on Python, with support for other languages coming soon.

Here you'll find guides to help you get started with Pants v2, comprehensive documentation on how to configure, run and customize Pants v2, and information on how to get help from the Pants community.

Get Started
./pants lint [args]

Lint source code.

Config section: [lint]

Basic options


Advanced options

default: False
Rather than linting all files in a single batch, lint each file as a separate process. Why do this? You'll get many more cache hits. Why not do this? Linters both have substantial startup overhead and are cheap to add one additional file to the run. On a cold cache, it is much faster to use `--no-per-file-caching`. We only recommend using `--per-file-caching` if you are using a remote cache or if you have benchmarked that this option will be faster than `--no-per-file-caching` for your use case.

default: None
Specifying a directory causes linters that support writing report files to write into this directory.

Deprecated options

default: False
Deprecated, will be removed in version: 2.1.0.dev0.
Use the renamed `--per-file-caching` option instead. If this option is set, Pants will now run per every file, rather than per target.
See `--per-file-caching`.
