- Introduced comprehensive test plan to guide development and ensure coverage.
- Documented test principles, execution harness, build steps, and test catalog.
- Categorized test cases by functionality (e.g., filesystem I/O, PieceTable semantics, buffer editing, undo system, etc.).
- Outlined regression tests and performance/stress scenarios.
- Provided a phased roadmap for implementing planned test cases.
- Removed standalone test executables (`test_undo`, `test_buffer_save`, `test_buffer_open_nonexistent_save`, etc.).
- Introduced `kte_tests` as a unified test runner.
- Migrated existing tests to a new minimal, reusable framework in `tests/Test.h`.
- Updated `CMakeLists.txt` to build a single `kte_tests` executable.
- Simplified dependencies, reducing the need for ncurses/GUI in test builds.
- Introduced comprehensive tests:
- `test_buffer_open_nonexistent_save.cc`: Save after opening a non-existent file.
- `test_buffer_save.cc`: Save buffer contents to disk.
- `test_buffer_save_existing.cc`: Save after opening existing files.
- Implemented `PieceTable::WriteToStream()` to directly stream content without full materialization.
- Updated `Buffer::Save` and `Buffer::SaveAs` to use efficient streaming via `PieceTable`.
- Enhanced editing commands (`Insert`, `Delete`, `Replace`, etc.) to use PieceTable APIs, ensuring proper undo and save functionality.
- Introduced `BufferNew` command to create and switch to a new unnamed buffer.
- Registered `BufferNew` in the command registry and updated keymap and help text.
- Implemented `cmd_buffer_new()` to handle buffer creation and switching logic.
- Created `piece-table-migration.md` outlining the steps to transition from GapBuffer to a unified PieceTable architecture.
- Included phased approach: extending PieceTable, Buffer adapter layer, command updates, and renderer changes.
- Detailed API changes, file updates, testing strategy, risk assessment, and timeline for each migration phase.
- Document serves as a reference for architecture goals and implementation details.
- Deleted `GapBuffer` class and its API implementations.
- Removed `AppendBuffer` selector and conditional `KTE_USE_PIECE_TABLE` macros.
- Eliminated legacy support in buffer APIs, file I/O, benchmarks, and correctness tests.
- Updated guidelines and comments to reflect PieceTable as the default and only buffer backend.
- Added `PieceTable` class for efficient text manipulation and implemented core editing APIs (`Insert`, `Delete`, `Find`, etc.).
- Integrated `PieceTable` into `Buffer` class with an adapter for rows caching.
- Enabled seamless switching between legacy row-based and new PieceTable-backed editing via `KTE_USE_BUFFER_PIECE_TABLE`.
- Updated file I/O, line-based queries, and cursor operations to support PieceTable-based storage.
- Lazy rebuilding of line index and improved management of edit state for performance.
- Introduced `CommandId::CenterOnCursor` to center viewport on the cursor line.
- Improved scrolling behavior in `ImGuiRenderer` to avoid aggressive centering and keep visible lines stable.
- Updated `make-app-release` to rename the output app to `kge-qt.app`.
- Adjusted padding in `ImGuiFrontend` to align with `ImGuiRenderer` settings for consistent scrolling.
- Bumped version to 1.4.1.
- Added `QtFrontend`, `QtRenderer`, and `QtInputHandler` for Qt-based UI rendering and input handling.
- Implemented support for theming, font customization, and palette overrides in GUITheme.
- Renamed and refactored ImGui-specific components (e.g., `GUIRenderer` -> `ImGuiRenderer`).
- Added cross-frontend integration for commands and visual font picker.
- Update input handling to retain SDL_TEXTINPUT after Tab insertion for better platform consistency.
- Allow multiple app instances in macOS by modifying `Info.plist`.
- Bump version to 1.3.8-alpha.
