- * Message format grammar:
- *
- *    messageFormatPattern := string ( "{" messageFormatElement "}" string )*
- *    messageFormatElement := argumentIndex [ "," elementFormat ]
- *    elementFormat := "plural" "," pluralStyle
- *                      | "select" "," selectStyle
- *    pluralStyle :=  pluralFormatPattern
- *    selectStyle :=  selectFormatPattern
- *    pluralFormatPattern := \\[ "offset" ":" offsetIndex ] pluralForms*
- *    selectFormatPattern := pluralForms*
- *    pluralForms := stringKey "{" ( "{" messageFormatElement "}"|string )* "}"
- *
- *
- * Message example:
- *
- * I see {NUM_PEOPLE, plural, offset:1
- *         =0 {no one at all}
- *         =1 {{WHO}}
- *         one {{WHO} and one other person}
- *         other {{WHO} and # other people}}
- * in {PLACE}.
- *
- * Calling format({'NUM_PEOPLE': 2, 'WHO': 'Mark', 'PLACE': 'Athens'}) would
- * produce "I see Mark and one other person in Athens." as output.
- *
- * See tests/message_format_test.dart for more examples.
