Defined in:
lib/kotoshu/grammar/pattern_matchers/word_list_matcher.rb

Overview

Matcher for word-list corrections.

Flags any token whose lowercase form is a key in the rule's corrections map. Useful for proper-noun capitalization (monday → Monday, english → English) where a single rule covers dozens of word pairs.

Rule shape:

patterns:
- conditions:
    - type: word_list_check
      corrections:
        monday: Monday
        tuesday: Tuesday
        english: English

The matcher only fires when the actual token text differs from the mapped correction (so "Monday" doesn't get flagged).
