recommendedcross-file

Cross-file rule. It runs in falcon's whole-project pass, analyzing relationships across every file rather than one file at a time. Configure it under the top-level cross-file key.

Require package names to be valid lower_case_with_underscores identifiers.

void main() {}

No diagnostics in this file.

Configure package-names

Set its severity in falcon.json under the cross-file section. See the configuration guide.

falcon.jsonjson

    "rules": {
      "style": {
        "package-names": "error"
      }
    }
  }
}

Or silence one occurrence with a suppression comment; the reason is required.
