Rules

"Rules" are how Bazel is extended to learn how to use new tools to build and test more languages and frameworks. Thus rules are a critical part of Aspect's Bazel platform.

This documentation is mirrored from open-source rule sets, making them easier to use:

  • a single search bar that finds results from all the rules we mirror - thanks Algolia!
  • versioned so you can find docs for the release you're using
  • better rendering than Stardoc, including deep-links to attributes
  • copy-paste usage examples including the load statement

Use the sidebar on the left to navigate all the rules we've mirrored so far. Come visit this site again as we'll continue to add more.

Aspect's Rules

The Bazel rules listed below are built and maintained by Aspect engineers. They are free to use and released under the Apache 2.0 License.

Support for our rules is included in Aspect.build Enterprise. Both our Support for Aspect Rules and Support for Bazel Ecosystem plans cover usage of any rules in this section.

If you use our free software, please consider supporting the development and maintenance of our open source Bazel rules through open collective. We also accept Bug Bounties and Feature Bounties to unblock your usage of our rules when you find something broken or missing.

Community Rules

Any rules mirrored on this site which don't appear in the "Aspect Rules" section above are owned and maintained by others in the Bazel community. Aspect engineers have good relationships with these maintainers and we can help to resolve issues or contribute fixes to those as well.

Support for community rules is included in Aspect.build Enterprise in the Bazel Ecosystem plan.
