YAMLlint is a linter for YAML files that checks both for syntax validity and cosmetic problems like line length, trailing spaces, indentation, etc. CodeRabbit runs YAMLlint version 1.37.1.

​
Files

YAMLlint will run on files with the following extensions:
  • .yaml
  • .yml

​

YAMLlint is a linter for YAML files.

​
Features

YAMLlint performs several checks:

​
Syntax checks

  • YAML validity
  • Document structure

​
Cosmetic checks

  • Line length limits
  • Trailing whitespace
  • Indentation consistency
  • Empty lines
  • Comments formatting

​
Configuration File

CodeRabbit loads repository .yamllint.yml or .yamllint.yaml files for this integration if they exist. If not, it passes inline configuration data to yamllint based on the selected review profile.

​
When we skip YAMLlint

CodeRabbit will skip running YAMLlint when:
  • YAMLlint is already running in GitHub workflows.

​
Ignored rules

The following YAMLlint rules are automatically ignored (noisy whitespace/indentation-only rules):
  • trailing-spaces - extra spaces at end of line
  • trailing spaces - alternate spelling sometimes emitted by YAMLlint
  • indentation - spaces don’t line up
  • new-line-at-end-of-file - new line at end of file
  • commas - commas in lists
  • colons - spacing around colons
  • comments - comment formatting
  • line-length - line length limits
  • document-start - document start requirements
  • quoted-strings - quoted strings
  • braces - whitespace inside braces

​
Profile behavior

CodeRabbit uses different YAMLlint rule sets based on the review profile:
  • Chill Mode: Uses the relaxed rule set
  • Assertive Mode: Uses the default rule set
