history
Project history and usage
yamllint is a Python linter for YAML files. It checks syntax validity, duplicate keys, and style problems such as line length, trailing spaces, indentation, comments, and document markers.
Project history
The GitHub repository was created on 2016-01-11. From the beginning of its public documentation, yamllint occupied the linter niche rather than the formatter niche: it reports problems and lets users tune rules rather than rewriting files wholesale.
The official docs organize the project around a rule system. Each rule is independent and can be enabled, disabled, or configured, with bundled `default` and `relaxed` configurations and custom configuration through files, inline `-d` values, or comments that disable checks in selected places.
Adoption history
yamllint became the default YAML linting package across many Unix-like environments. The official quickstart documents installation on Fedora/CentOS, Debian/Ubuntu, macOS through Homebrew, FreeBSD, OpenBSD, Alpine Linux, pip, and source builds.
Its adoption tracks YAML becoming infrastructure glue: CI definitions, Ansible playbooks, Kubernetes manifests, packaging metadata, and documentation configs all benefit from a linter that catches both invalid YAML and review-noise style drift.
How it is used
Common usage is `yamllint file.yml other-file.yaml`, `yamllint .` for a directory, or `echo ... | yamllint -` for stdin. Output formats include standard terminal output and parsable output for editor integrations.
Configuration is normally kept in `.yamllint`, `.yamllint.yaml`, or `.yamllint.yml` in a project tree, a file referenced by `YAMLLINT_CONFIG_FILE`, or XDG config paths. Configurations can extend the default ruleset and adjust rule severity to warnings or errors.
Why package nerds care
yamllint is one of the canonical examples of a small language-specific linter becoming packaging infrastructure. It is not tied to one YAML-using ecosystem, so it appears wherever maintainers need reproducible checks for human-edited YAML.
It also matters because YAML has edge cases that parsers may accept but humans do not want in shared repos, such as duplicate keys, truthy values, bad indentation, and noisy whitespace. yamllint gives package maintainers a standard policy layer for those files.
