v0.9.0-rc.1

What's New in libchewing 0.9.0-rc.1 (July 16, 2024)

• Features

  • Support two new input modes:
    • Fuzzy mode - support prefix search, partial zhuyin search, toneless input.
    • Simple mode - like the traditional input method on Windows 95 which does
      not perform any intelligent phrasing.
  • Allow space key for pagination regardless of space_is_select_key mode.
  • Merge DOWN and SPACE key behavior in pagination.
  • A new option to disable fullwidth toggle key.
  • Workman layout support.
  • Load embedded mini dictionary if system dictionaries were not found.
  • Show notification about mode switches triggered by input.
  • Automatically load extra dictionaries found in search path
    • ${CHEWING_PATH}/dictionary.d/*.dat

• Developer Features

  • BREAKING: Remove language_mode and character_form methods
  • BREAKING: Remove unused pinyin.tab file
  • BREAKING: Remove most unused C code
  • Bump minimum supported Rust version to 1.77
  • Enable ELF symbol versioning. All existing symbols are marked as version
    CHEWING_0.5 and new symbols from this release are marked as CHEWING_0.9.
  • A new set of configuration API:
    • chewing_config_has_option
    • chewing_config_get_int

• Bug Fixes

  • Separate special handling by pinyin variants (#298)
