Changelog

All notable changes to TextTools will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

[0.3.0] — 2026-02-21

Added

  • Default tab is now Clean (was Find/Replace)
  • Keyboard shortcuts: Ctrl+F (find), Ctrl+H (replace), F3 (find next)
  • Encoding conversion button (F-001): re-saves file as UTF-8
  • Cursor position and character count in status bar
  • Save As (was stubbed)
  • Window geometry and splitter positions persist across sessions (QSettings)

Fixed

  • Encoding label now shows "utf-8" for ASCII files (ASCII is a subset of UTF-8)

[0.2.0] - 2026-02-21

Added

  • TextDocument dataclass — core domain model for loaded files (filepath, content, encoding, modified)
  • CleaningOptions dataclass — configuration for text cleaning passes
  • TextProcessingService — stateless text cleaning: trim_whitespace, clean_whitespace, remove_tabs, apply_options
  • FileService — atomic file save (tempfile.mkstemp + os.replace), encoding detection via chardet with 0.7 confidence threshold
  • MainViewModel — full signal/slot implementation: document_loaded, encoding_detected, file_saved, error_occurred, status_changed; slots for load_file, save_file, apply_cleaning, replace_all
  • MainWindow — wires QFileSystemModel file tree, all checkbox/button signals, find/replace with wrap-around cursor, ViewModel signal handlers
  • chardet>=5.0.0 runtime dependency for encoding detection
  • mypy, black, isort dev dependencies in requirements.txt
  • 60 unit and integration tests (100% coverage on models and TextProcessingService; 98% on ViewModel)
  • AGENTS.md rewritten with TextTools-specific architecture reference and widget objectName table

Changed

  • Renamed project from Template-Desktop-Application to TextTools
  • main.py composition root now wires FileService + TextProcessingService → MainViewModel → MainWindow; logging to stdout only
  • MainWindow changed from QMainWindow subclass to a plain Python controller — self.ui is the loaded .ui QMainWindow, preventing nested-QMainWindow sizing bugs
  • All template/scaffold files removed (ExampleModel, ExampleService, example_model.py tests)
  • CI workflow updated: develop → testing branch, action versions pinned to v4/v5, pip → uv
  • .ui window title changed from "MainWindow" to "TextTools"
  • pyproject.toml mypy config: added explicit_package_bases = true

Fixed

  • QFileSystemModel import moved from PySide6.QtGui to PySide6.QtWidgets (correct for PySide6 6.10.x)
  • Black/isort formatting applied to all source files

[0.1.0] - 2025-11-02

Added

  • MVVM architecture scaffold: ExampleModel, MainViewModel, ExampleService, MainWindow
  • Qt Designer .ui file loading via QUiLoader with findChild() widget access pattern
  • Dependency injection wired in main.py:create_application()
  • Test suite: 9 unit tests for Model (100% coverage), 10 unit tests for ViewModel (96% coverage), 3 integration tests
  • ServiceProtocol pattern using typing.Protocol for mockable service interfaces
  • Branch protection system: pre-commit hook blocks commits to main, .agents/branch_protection.py for AI agent checks
  • Coverage auto-configured in pyproject.toml (addopts); no extra flags needed when running pytest
  • Logging to both file (app.log) and console

Dependencies

  • PySide6 >= 6.8.0
  • pytest >= 8.3.0, pytest-qt >= 4.4.0, pytest-mock >= 3.14.0, pytest-cov >= 5.0.0
  • Python 3.14, Linux only
