A compact command line linting tool for validating YAML files, using the parsing facility of the Symfony Yaml Component.

usage: yaml-lint [options] [input source]
  input source    Path to file(s), or "-" to read from standard input
  -q, --quiet     Restrict output to syntax errors
  -h, --help      Display this help
  -V, --version   Display application version

To get started using yaml-lint in a project, install it with Composer:

composer require --dev j13k/yaml-lint

It can then be run from the project's vendor/bin directory.

To set up yaml-lint globally, install it in the Composer home directory:

composer global require j13k/yaml-lint

It can then be run from the bin directory of Composer home (typically ~/.composer/vendor/bin).

A binary edition , yaml-lint.phar, is available for download with each release. This embeds the latest stable version of the Symfony Yaml component that is current at the time of the release.

The binary can be conveniently installed using PHIVE:

phive install yaml-lint

yaml-lint is bundled in the phpqa Docker image, which provides a suite of static analysis tools for PHP. See the phpqa project for installation and usage instructions.
