Super-Linter

Super-linter is a ready-to-run collection of linters and code analyzers, to help validate and fix your source code.

The goal of super-linter is to help you establish best practices and consistent formatting across multiple programming languages, and ensure developers are adhering to those conventions.

Super-linter analyzes source code files using several tools, and reports the issues that those tools find as console output, and as GitHub Actions status checks. You can also run super-linter outside GitHub Actions.

Super-linter can also help you fix linting and formatting issues.

Here are some notable Super-linter features:

• MIT License: Super-linter is licensed under a MIT License.
• Independent project: Super-linter is maintained by a team of independent developers and is not commercially backed by any entity that might influence the course of the project.
• Widely used: Super-linter is the most widely used and forked project of this kind.
• Runs linters in parallel: Since v6, Super-linter parallelizes running all the included linters, leading to scanning massive code repositories in seconds.
• Highly curated set of linters: Avoid including linters that implement overlapping checks, reducing bloat, scanning times, and container image size.
• Run on GitHub Actions or other environments: Super-linter runs on GitHub Actions and other runtime environments, with the only dependency of an OCI-compatible container runtime engine, such as Docker.
• Lean codebase: Super-linter doesn't reinvent the wheel, and builds on top of established tools and standards, such as GNU Parallel.
• Extensive test suite: Super-linter includes an extensive test suite that covers every single linter and analyzer that Super-linter ships.
• Original design: to the best of our knowledge, Super-linter is the first open-source, fully-containerized linting suite. Other projects borrow ideas and design choices from Super-linter (and we're cool with that :).
