Introducing GitHub Super Linter: one linter to rule them all

Organising a brand new repository with all the correct linters for the various kinds of code will be time consuming and tedious. So many instruments and configurations to select from and infrequently multiple linter is required to cowl all of the languages used.

The GitHub Super Linter was constructed out of necessity by the GitHub Providers DevOps Engineering group to take care of consistency in our documentation and code whereas making communication and collaboration throughout the corporate a extra productive expertise. Now we’re open sourcing that so everybody can use and enhance it!

The Super Linter solves many of those necessities via automation. Some included options:

  • Stop damaged code from being uploaded to grasp branches
  • Assist set up coding greatest practices throughout a number of languages
  • Construct pointers for code format and format
  • Automate the method to assist streamline code critiques
  • With these fundamental standards, we ought to be transport higher, cleaner, and extra steady code internally and to our clients and companions

What’s it?

The Tremendous Linter is a supply code repository that’s packaged right into a Docker container and known as by GitHub Actions. This permits for any repository on to name the Tremendous Linter and begin using its advantages.

The Tremendous Linter will at present help quite a lot of languages and extra coming sooner or later. For particulars on languages, take a look at the

The way it works

Once you’ve set your repository to start out operating this motion, any time you open a pull request, it’ll begin linting the code case and return by way of the Standing API. It’ll let if any of your code adjustments handed efficiently, or if any errors had been detected, the place they’re, and what they’re. This then permits the developer to return to their department, repair any points, and create a brand new push to the open pull request. At that time, the Tremendous Linter will run once more and validate the up to date code and repeat the method. You possibly can configure your department safety guidelines to verify all code should cross earlier than having the ability to merge as a further measure.

There’s a ton of customization with flags and templates that may enable you to customise the Tremendous Linter to your particular person repository. Simply observe the detailed instructions on the Super Linter repository and the Super Linter wiki.

This software may also be useful for any repository the place a number of sorts of code and/or documentation all dwell collectively (monorepo).

Default guidelines

Standardizing a rule set throughout the Tremendous Linter has been an fascinating problem as every developer is exclusive in how they code. Because of this we enable customers to make use of any guidelines for the linter as they see match for his or her repository. However, if no ruleset is outlined, we should default to a sure commonplace.

The rule set for Ruby and Rails are pulled from the Ruby gem: rubocop-github and observe the identical guidelines and versioning we use on

For different languages, we select what’s the default when putting in the linter equivalent to: coffeelint or yamllint. For others, we attempt to discover a comfortable center floor that lays the straightforward groundwork and helps set up some greatest practices like: Markdownlint or pylint.

The great thing about that is, out of the field you’ll begin establishing the framework, and your group can resolve at any level, if further customization is required, you’ve all the flexibility to take action.

Simply navigate to the Tremendous Linter and duplicate templates from the TEMPLATES folder to your native repository.

Be part of within the enjoyable

We encourage you to arrange this motion and begin the method of cleansing up your codebase and constructing your group’s requirements and greatest practices.

How can I contribute?

We’re all the time trying to replace greatest practices, add further languages, and make the software simpler for consumption. If you happen to’d like to assist contribute to this motion, take a look at our contributing guide.
