Documentation

Overview

Package pattern parses brace-delimited formatter patterns.

It provides the small tokenizer used by ECMA-402 partition algorithms before formatter packages substitute localized field values.

Only internal ECMA-402 and formatter code should use this package; public callers receive already formatted strings or parts.

Package pattern parses generated CLDR placeholder patterns.
