ryl 0.3.3

Fast YAML linter (Rust) packaged for PyPI

ryl

ryl - the Rust Yaml Linter is intended to ultimately be a drop in replacement for yamllint. It's only just begun and isn't ready for use yet though. I'll update and post info as it becomes ready.

Usage

ryl accepts one or more paths: files and/or directories.

Basic:

ryl <PATH_OR_FILE> [PATH_OR_FILE...]

Behavior:

• Files: parsed as YAML even if the extension is not .yml/.yaml.
• Directories: recursively lints .yml and .yaml files.
  • Respects .gitignore, global git ignores, and git excludes.
  • Does not follow symlinks.

Exit codes:

• 0 when all parsed files are valid (or no files found).
• 1 when any invalid YAML is found.
• 2 for CLI usage errors (for example, no paths provided).

Examples:

# Single file
ryl myfile.yml

# Multiple inputs (mix files and directories)
ryl config/ another.yml

# Multiple directories
ryl dir1 dir2

# Explicit non-YAML extension (parsed as YAML)
ryl notes.txt

Help and version:

• ryl -h or ryl --help shows auto-generated help.
• ryl -V or ryl --version prints the version.

The CLI is built with clap, which auto-generates --help and --version.

Configuration

• Flags:
  • -c, --config-file <FILE>: path to a YAML config file.
  • -d, --config-data <YAML>: inline YAML config (highest precedence).
  • --list-files: print files that would be linted after applying ignores and exit.
  • -f, --format, -s, --strict, --no-warnings: reserved for compatibility.
• Discovery precedence: inline --config-data > --config-file > env YAMLLINT_CONFIG_FILE (global) > nearest project config up the tree (.yamllint, .yamllint.yml, .yamllint.yaml) > user-global ($XDG_CONFIG_HOME/yamllint/config or ~/.config/yamllint/config) > built-in defaults.
• Per-file behavior: unless a global config is set via --config-data, --config-file, or YAMLLINT_CONFIG_FILE, each file discovers its nearest project config. Ignores apply to directory scans and explicit files (parity).
• Presets and extends: supports yamllint’s built-in default, relaxed, and empty via extends. Rule maps are deep-merged; scalars/sequences overwrite.
