mcpp-community

Use when contributing to the mcpp project — submitting bug fixes, new features, code optimizations, documentation improvements, or any PR. Covers issue creation, branch conventions, build verification, CI requirements, and PR workflow using gh and git.

Use when releasing a new version of mcpp — bumps version, creates tag, triggers release CI, and monitors until all platforms succeed. Covers the full release checklist to avoid common pitfalls like version string mismatches.

Use when helping users install, configure, or use mcpp — the C++23 modular build tool. Covers installation, project creation, building, dependency management, toolchain management, workspace setup, packaging, diagnostics, and troubleshooting.

Authoring conventions, design principles, and file formats for the d2mcpp (D2X) Modern C++ tutorial project. Use this whenever you add or edit a C++ language-feature lesson — a book chapter, a dslings exercise, a reference solution, or when registering them in SUMMARY/xmake/changelog. Trigger it for any request like "add a chapter for X", "write a dslings exercise for fold expressions", "add the constexpr lesson", "fill the cpp14 section", or anything touching book/src, book/en/src, dslings/, or solutions/. Even small edits should follow these conventions so the bilingual + book/code/checker artifacts stay in sync.

为 mcpp 项目应用 Modern/Module C++ (C++23) 编码风格。适用于编写或审查带模块的 C++ 代码、命名标识符、组织 .cppm/.cpp 文件，或用户提及 mcpp、module C++、现代 C++ 风格时。
