Usage ----- [](#usage) ``` 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 -t, --parse-tags Enable parsing of custom YAML tags (symfony/yaml 3+ only) -h, --help Display this help -V, --version Display application version ``` Install ------- [](#install) ### Composer [](#composer) 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`). Note **Binary Name Conflict**: Both `j13k/yaml-lint` and `symfony/yaml` provide a `yaml-lint` binary. If you see this message during installation: ``` Skipped installation of bin bin/yaml-lint for package j13k/yaml-lint: name conflicts with an existing file ``` You can either call the binary directly with `vendor/j13k/yaml-lint/bin/yaml-lint`, or create a symlink: ``` ln -sf ../j13k/yaml-lint/bin/yaml-lint vendor/bin/yaml-lint ``` See [\#181](https://github.com/j13k/yaml-lint/issues/181) for details. ### Binary [](#binary) A binary edition , `yaml-lint.phar`, is available for download with [each release](https://github.com/j13k/yaml-lint/releases). 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](https://phar.io/): ``` phive install yaml-lint ``` #### Verifying Signatures [](#verifying-signatures) Release binaries are signed with GPG. To verify the signature: 1. Download both `yaml-lint.phar` and `yaml-lint.phar.asc` from the [releases page](https://github.com/j13k/yaml-lint/releases) 2. Import the public key: ``` gpg --recv-keys 38A182AB413064D7 ``` Or download it from this repository: ``` curl -O https://raw.githubusercontent.com/j13k/yaml-lint/master/j13k_users_noreply_github_com.pub gpg --import j13k_users_noreply_github_com.pub ``` 3. Verify the signature: ``` gpg --verify yaml-lint.phar.asc yaml-lint.phar ``` You should see: `Good signature from "John Fitzpatrick (Software signing key) "` ### Docker [](#docker) yaml-lint is bundled in the [phpqa Docker image](https://hub.docker.com/r/jakzal/phpqa/), which provides a suite of static analysis tools for PHP. See the [phpqa project](https://github.com/jakzal/phpqa) for [installation and usage instructions](https://github.com/jakzal/phpqa#running-tools).
