v0.8.0-rc.1

Hi,

大家好，從 2022 年 4/29 開始的 Rust Rewrite (89ef2a8) 終於進入一個新的里程碑！
0.8.0 將會是第一個完全用 Rust 重寫的 libchewing 的第一個 release，希望大家幫忙
多多測試。

重大變更：新字典格式與舊有工具不相容

現有使用者字典將會自動備份及轉移，但舊有工具將無法直接操作字典檔案。
請使用新的 chewing-cli 工具來檢視、傾出或建構使用者字典。最終版本將提供更新的文件說明。

What's New in libchewing 0.8.0-rc.1 (UNRELEASED)

BREAKING CHANGE: New dictionary format is not compatible with old tools.
Existing user dictionary will be automatically backed up and migrated
however old tools will not be able to manipulate the dictionary directly.
Use the new chewing-cli tool to inspect/dump/build user dictionaries.
Updated documentation will be provided in final release.

• Added

  • A new command line tool chewing-cli is included in this release. It can
    create or inspect dictionary files.
  • Reintroduce DictionaryMut as a separate trait.

• Changed

  • CMake default preset switched to build with rust.
  • CMake minimum required version bumped to 3.24.0.
  • Improved TrieBufDictionary::from ergonomics.
  • Rename DictEntries to Entries.
  • Ensure all fallible API returns Error.
  • Improved algorithm so using Tab key to find alternative phrasing is more
    responsive.
  • Easy symbol input now accepts arbitrary long "symbols". (rust)

• Removed

  • HashMap implemented Dictionary was removed.

• Documentation

  • Clarify the accepted value of chewing_handle_Default method.

Full Changelog: v0.7.0...v0.8.0-rc.1

v0.7.0

What's New in libchewing 0.7.0 (Apr 7, 2024)

This is the first beta release of the Rust rewrite. The library has been tested
with the AFL++ fuzzer and most of the obvious bugs have been fixed so it should
not crash for normal use. Now we invite power users to daily drive the beta
release in order to find more subtle bugs.

The Rust rewrite is ABI compatiable with previous releases. The most notable
difference with the C version includes a new portable dictionary format that can
be used both as system dictionary and user dictionary. Users with existing user
phrase dictionary will be automatically migrated. Old files will be backed up
automatically. With these change we will be able to support dictionary sharing
and loading multiple dictionaries in future releases.

• Future roadmap

  • 0.8.x after bug bashing this version will be the first public release with
    rust implementation as the default.
  • 0.9.x will focus on the stablization of the Rust crate API.
  • 1.0.0 will be the first public release of the Rust API. C implementation
    will be removed from the repository.

• Added

  • Added Colemak-DH ANSI/Orth layout support
  • Replace bespoke RIFF+TLV file format with standard DER format (rust)
  • Supporting migrating user dictionary file to new format. (rust)
  • Allow creating in memory user dictionary (rust)
  • New chewing-cli tool can be used to create or inspect dictionary files. (rust)
  • New chewing-cli tool can dump dictionary as or import from CSV file. (rust)
  • Audit dependencies using cargo-vet (rust)

• Changed

  • Buffer user dictionary changes and flush in background without blocking main
    thread (rust)

• Bug fixed

  • Some unsigned underflow issue found by afl++ (rust)
  • Skip symbol selection if preedit buffer is empty (rust)
  • Allow numlock in selection mode (rust)
  • Avoid infinite recursion (rust)
  • Ensure to return KeyBehavior::Commit when we push to commit buffer (rust)
  • Adjust selection offset after delete symbols (rust)
  • Disable trace logging if no logger is enabled (rust)
  • Should not start selection in English mode (rust)
  • Use offset to select from paginated phrase list (rust)

• Documentation

  • Added document for fuzzers (rust)
  • Describe how to compile dictionary files
  • Update build instruction and Rust MSRV info

• Testing

  • Added a fuzzer harness with afl++ (rust)

New Contributors

• @mlouielu made their first contribution in #441

The Rust rewrite is ABI compatiable with previous releases. The most notable

and two new user dictionary format. Users with existing user phrase dictionary
will be automatically migrated to either a new sqlite3 schema or CDB based
