+
+    Parameters:
+        check: Avoid writing any formatted files back; instead, exit with a non-zero status code if any files would have been modified, and zero otherwise
+        config: Path to the `pyproject.toml` or `ruff.toml` file to use for configuration
+        diff: Avoid writing any fixed files back; instead, output a diff for each changed file to stdout
+        target_version: The minimum Python version that should be supported [possible values: py37, py38, py39, py310, py311, py312]
+        preview: Enable preview mode; enables unstable formatting
+        exclude: List of paths, used to omit files and/or directories from analysis
+        extend_exclude: Like --exclude, but adds additional files and directories on top of those already excluded
+        respect_gitignore: Respect file exclusions via `.gitignore` and other standard ignore files
+        force_exclude: Enforce exclusions, even for paths passed to Ruff directly on the command-line
+        no_cache: Disable cache reads
+        isolated: Ignore all configuration files
+        cache_dir: Path to the cache directory [env: RUFF_CACHE_DIR=]
+        stdin_filename: The name of the file when passing it through stdin
+        verbose: Enable verbose logging.
+        quiet: Print lint violations, but nothing else.
+        silent: Disable all logging (but still exit with status code "1" upon detecting lint violations).
