Also ignore the throwaway upstream STL/ clone (the curated subset lives in msvc-stl/). * docs(cpp11/00): overhaul auto/decltype chapter (zh + en) - add section 二 真实案例 — verbatim std::begin/cbegin cited from the vendored msvc-stl/ basis - restructure to 5 sections; section 三 注意事项 now also covers auto's const/reference stripping - exercises: topic-specific Tips, add char-case asserts to exercise 0, new exercise -5 (const/reference stripping & preservation) - practice section: list all 6 exercises, single entry checker command, collapsible d2x setup, per-chapter discussion link - footer: add mcpp-community org + d2x tool links - fix typos (变得 / 显式) - register exercise -5 in dslings + solutions xmake * update xmake.lua --- .agents/skills/d2mcpp-authoring/SKILL.md | 182 +

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. +--- + +# d2mcpp (D2X) Authoring Conventions + +d2mcpp teaches **Modern C++ core language features** through a tightly coupled +quartet: **Book (mdBook) + Code (dslings exercises) + Solution + Auto-checker +(`d2x checker`)**, all of it **bilingual (zh + en)**. A "lesson" is never one +file — it is a coordinated set across several directories. The cardinal sin here +is producing a half-set (a chapter with no exercise, a zh file with no en +counterpart, an exercise not registered in xmake). This skill exists so every +lesson lands complete and consistent. + +Read `references/anatomy.md` for the full directory map and the exact list of +files every lesson must touch. Use the ready-made scaffolds in `assets/` rather +than reconstructing format from memory. + +## The design principle (decide this BEFORE writing) + +The project is organized **by standard** (`cpp11/ cpp14/ cpp17/ cpp20/ cpp23/`). +Honor that axis: + +- **Teach each feature as the standard that introduced it actually delivered + it** — the historical state, compiled at its introduction standard. The + compiler-driven (dslings) format is at its best when the learner feels the + C++11-era restriction first (e.g. `constexpr` single-return, `std::is_pod`, + copy-elision behavior). Folding every later refinement back into the + introduction chapter erases that, and empties out the later-standard sections. +- **Independent later capabilities become their own chapter under the later + standard's section** — this is what fills `cpp14/17/20`. Examples: fold + expressions → cpp17, `using enum` → cpp20, designated initializers → cpp20, + `if constexpr` → cpp17, `decltype(auto)` → cpp14, `consteval`/`constinit` → cpp20. +- **Pure refinements / rule-tweaks / deprecations stay in the introduction + chapter as a short "特性演进 / Feature Evolution" note** with a cross-link + forward — they are not chapter-worthy on their own. Examples: `auto x{1}` + deduction change, `std::is_pod` deprecation pointer, guaranteed copy elision + remark, P0136 inheriting-constructor semantics fix. +- **Compile each chapter at its introduction standard.** Do not globally pin a + newer standard. If one exercise genuinely needs a later standard, make it an + **explicit, commented exception** in xmake — never a bare `-- TODO` hack. + +Background and the full per-feature evolution analysis live in +`.agents/docs/2026-06-08-cpp11-feature-evolution-and-cxx20-baseline.md`. Consult +it when deciding where a feature's later improvements should go. + +The decision rule, compactly: + +| Kind of later change | Where it goes | +|---|---| +| New independent syntax/ability | New chapter in the later standard's section | +| Relaxation/tweak/deprecation | "Feature Evolution" note in the intro chapter + forward link | + +## The unit of work: one lesson = these files, all bilingual + +When adding a feature numbered `NN` with slug `topic` (e.g. `06-scoped-enums`): + +1. `book/src//NN-topic.md` — zh chapter +2. `book/en/src//NN-topic.md` — en chapter (translate prose, keep code identical) +3. `dslings//NN-topic-K.cpp` — one or more exercises (`K` = 0,1,2…), zh comments +4. `dslings/en//NN-topic-K.cpp` — en exercises (translate comments only) +5. `solutions//NN-topic-K.cpp` — reference solution per exercise +6. Register each exercise target in `dslings//xmake.lua` +7. Register each solution target in `solutions/xmake.lua` +8. Add the chapter line to **both** `book/src/SUMMARY.md` and `book/en/src/SUMMARY.md` +9. Add a changelog entry to **both** `book/src/changelog.md` and `book/en/src/changelog.md` + +Missing any of these = an incomplete lesson. `references/anatomy.md` has the +exact registration snippets and SUMMARY/changelog line formats. + +## Naming and numbering + +- Chapter/exercise prefix is a **two-digit** sequence `NN` within the standard + section; slug is **kebab-case** and matches book + dslings + solutions. +- Exercises split into `-0`, `-1`, … by sub-topic; a single-exercise chapter has + no numeric suffix on the dslings target name but the file is still `NN-topic.cpp`. +- The **`d2x checker `** name is the slug (and `-1`, `-2` for + later exercises) — it omits the `NN-` prefix. Keep checker names, file names, + and book references mutually consistent. + +## Book chapter format + +Use `assets/chapter.zh.md` / `assets/chapter.en.md`. Required structure, in order: + +1. Language-switch header `
🌎 [中文] | [English]` + link defs. + - zh links: `[中文]: ./NN-topic.html` and `[English]: ../en//NN-topic.html` + - en links: `[中文]: ../..//NN-topic.html` and `[English]: ./NN-topic.html` +2. `# 标题 - english name` (zh) / `# English Title` (en), then a one-paragraph + intro that states the feature **was introduced in C++NN** and what problem it solves. +3. Resource table `| Book | Video | Code | X |` — cppreference link + markdown + permalink + video link + first practice-code permalink. +4. Bold motivation blocks: `**为什么引入?**`, `**和……的区别?**`. +5. Numbered Chinese-numeral sections, in order: `## 一、基础用法和场景`, + `## 二、真实案例 - STL 中的 `, `## 三、注意事项`, + `## 四、练习代码`, `## 五、其他`. +6. `## 二、真实案例` corroborates the feature with **real, verbatim STL code** + quoted from the in-repo `msvc-stl/` basis — see "The 真实案例 section" below. +7. `## 四、练习代码` lists **every** exercise topic of the chapter (`-0`, `-1`, …, + matching the dslings/xmake count) with dslings links as an index, but the checker + block shows only the **single entry** command `d2x checker ` — `d2x` auto- + advances through the remaining exercises, so do NOT list one command per exercise. + Then a `### 练习交流讨论` link to the chapter's forum thread. Each exercise's own + `d2x checker -K` name and a Tips line **specific to that exercise** belong in + that exercise file's header, not in the book. +8. `## 五、其他` is the fixed footer (forum / repo / video list / xlings links). +9. If the feature evolved later, add a **`## 特性演进 / Feature Evolution`** + block before `## 五、其他` — introduced standard + bullet list of later + refinements + forward links to the later-standard chapters. + +Keep prose tone consistent with existing chapters: explanatory, example-driven, +short code blocks with inline comments showing the failure and the fix. + +### The 真实案例 / Real-World Case section (msvc-stl basis) + +`## 二、真实案例` exists to prove the feature earns its place by showing **real +production code, quoted verbatim** — never invented, never paraphrased. The single +source of truth is the in-repo vendored MSVC STL basis at the top-level +**`msvc-stl/`** (the complete upstream `stl/` subtree; `msvc-stl/SOURCE.md` records +the pinned upstream commit and how to refresh it). Rules: + +- Quote from `msvc-stl/stl/inc/
` (or `src/`) **byte-for-byte**; mark any + elision with `(有删节)` / `(abridged)`. Do not reconstruct from memory. +- Keep internal macros (`_NODISCARD`, `_CONSTEXPR17`, `_STD`, …) as written and add + one line telling the reader they are library-internal and ignorable. +- Pick a usage that **echoes a syntax point from `## 一`** (e.g. `std::begin`'s + `auto … -> decltype(...)` for the auto/decltype chapter), so the section reads as + "you use it this way → the standard library does too". +- **Scope-lock to the chapter's standard**: a `cpp11` chapter quotes C++11-era + usage only; do not show later forms (e.g. `decltype(auto)`). +- Link to the **local `msvc-stl/` path**, not the upstream GitHub repo, so the + citation stays pinned to the vendored snapshot. +- Every chapter should carry this section. If a feature genuinely has no + representative usage in the STL implementation, omit it and state why in the PR. + +## dslings exercise format + +Use `assets/exercise.cpp`.
