Defined in:

Overview

Resolves which language a check should run in.

The CLI’s –language flag accepts:

- omitted / "auto"   → detect from content, fall back if needed
- "default"          → Configuration.default_language (no detection)
- any other code     → used as-is

Pure logic — no IO. Detection delegates to Kotoshu::Language.detect which uses character-set heuristics and needs no model download. A detection only “sticks” if the detected language is set up (Kotoshu.setup? returns true); otherwise the configured default is used and a fallback note is included in the result.

    Raw –language flag value.

  • default_language (String, nil) —

    Configuration.default_language.

  • detector (#detect) (defaults to: Kotoshu::Language) —

    Object responding to .detect(text) -> String|nil. Defaults to Kotoshu::Language.
