How are identified applicable files

  • File extensions: .clj, .cljs, .cljc, .edn

How the linting is performed

  • clj-kondo is called one time by identified file

Example calls

clj-kondo --lint myfile.clj

clj-kondo --lint --config .clj-kondo/config.edn myfile.clj

Help content

clj-kondo v2022.04.25


Options:

  --lint <file>: a file can either be a normal file, directory or classpath. In the
    case of a directory or classpath, only .clj, .cljs and .cljc will be
    processed. Use - as filename for reading from stdin.

  --lang <lang>: if lang cannot be derived from the file extension this option will be
    used. Supported values: clj, cljs, cljc.

  --filename <file>: in case stdin is used for linting, use this to set the
    reported filename.

  --cache-dir: when this option is provided, the cache will be resolved to this
    directory. If --cache is false, this option will be ignored.

  --cache: if false, won't use cache. Otherwise, will try to resolve cache
  using `--cache-dir`. If `--cache-dir` is not set, cache is resolved using the
  nearest `.clj-kondo` directory in the current and parent directories.

  --config <config>: config may be a file or an EDN expression. See
    https://cljdoc.org/d/clj-kondo/clj-kondo/2022.04.25/doc/configuration

  --config-dir <config-dir>: use this config directory instead of auto-detected
    .clj-kondo dir.

  --parallel: lint sources in parallel.

  --dependencies: don't report any findings. Useful for populating cache while linting dependencies.

  --copy-configs: copy configs from dependencies while linting.

  --skip-lint: skip lint/analysis, still check for other tasks like copy-configs.

  --fail-level <level>: minimum severity for exit with error code.  Supported values:
    warning, error.  The default level if unspecified is warning.

  --debug: print debug information.
