课程代码仓库初始化:Part1 (144) + Part3 (29) 全量生成与验证
把川大 wiki「02.Qt方向」课程代码整理为 CMake 管理的可编译运行项目。
Part1 C/C++ 强化 (p01/, 144 目标, host gcc/g++ 构建, 全绿):
- 修复全部编译失败:补 <cstring>/<fstream>/<iomanip>/<vector> 等缺失头
(common_fix + infer_stl_includes 自动检测注入)、修正 pause() 壳注入
(改检测已转换后的 pause 调用)、namespace 提升出函数体、const 成员函数
正确性、dedupe 不再破坏函数重载集、K&R 隐式 int / 动态异常规范等
C++17 移除特性的可编译等价改写。
- 目录采用深缩写 p01/ch04/s03/ (原 part1_cpp/ch04_class_object/03_ctor_dtor)。
Part3 Qt 桌面 (p03/, 29 目标, 隔离 Qt 5.14.2 构建, 全绿):
- gen_part3.py: Qt 外壳模板 (main+QApplication+show, QTimer 自动退出便于
offscreen 验证)、AUTOMOC + .moc include、rewrite_* 处理散文混入/重载/
资源依赖、生成占位 png/gif + .qrc + rundata 样例数据。
- 修正 QLable 笔误、全角分号、.→->、Windows 路径、QApplication 阻塞事件
循环改为 QCoreApplication 等。
任务1 概念/版本验证:
- tools/std_probe.py: 跨 -std= 编译探针 (--pedantic-errors 让已废除特性硬失败)。
- tools/demo_versions/: K&R 隐式 int、三目左值、void* 转换、enum 赋整、
const 经指针、动态异常规范 共 6 个跨版本演示。
- docs/VERSION_NOTES.md: 每条「原文说法→C17/C++17 是否成立→何版本成立→已验证」。
文档: 顶层 README、docs/SOURCE_PAGES.md (页面→目录映射)、
docs/ERRATA.md (Part1 修正)、docs/ERRATA_part3.md (Part3 修正)。
另修复 tools/run.sh / run_qt.sh 的 ${1:?...} 引号语法 bug。
隔离 Qt 验证: ldd 0 系统 Qt 引用; 173/173 目标全绿; p03 offscreen 运行通过。
