yamllint is a Python-based linter for YAML files that checks syntax validity plus style issues like key duplication, line length, trailing spaces, and indentation. It runs as a CLI, supports custom rule configurations, inline disables, and parsable output for editor integration.
Use cases
- lint yaml files for syntax errors
- check yaml indentation and formatting
- enforce yaml style rules in ci
- detect duplicate keys in yaml
- validate yaml config files before deployment
- integrate yaml linting into vim or emacs
When to choose
- you need configurable yaml style and syntax checking
- you want a lightweight CLI linter with parsable output for editors and CI
- you need per-line or per-file rule disables and ignore patterns
When to avoid
- you need linting for formats other than YAML
- you want a full YAML parser or data transformation library rather than a linter
