はじめに(Introduction)
N4910 Working Draft, Standard for Programming Language C++
n4910は、ISO/IEC JTC1 SC22 WG21の作業原案(Working Draft)です。
公式のISO/IEC 14882原本ではありません。
ISO/IEC JTC1 SC22 WG21では、可能な限り作業文書を公開し、幅広い意見を求めています。
一連の記事はコード断片をコンパイルできる形にする方法を検討してコンパイル、リンク、実行して、規格案の原文と処理系(g++, Clang++)との違いを確認し、技術内容を検討し、ISO/IEC JTC1 SC22 WG21にフィードバックするために用います。
また、CERT C++, MISRA C++等のコーディング標準のコード断片をコンパイルする際の参考にさせていただこうと考えています。CERT C++, MISRA C++が標準化の動きとの時間的なずれがあれば確認できれば幸いです。また、boostライブラリとの関連、Linux OS, TOPPERSカーネル、g++(GCC), clang++(LLVM）との関係も調査中です。
何か、抜け漏れ、耳より情報がありましたらおしらせくださると幸いです。
<この項は書きかけです。順次追記します。>
背景(back ground)
C/C++でコンパイルエラーが出ると、途方にくれることがしばしばあります。
何回かに１回は、該当するエラーが検索できます。
ただ、条件が違っていて、そこでの修正方法では目的を達成しないこともしばしばです。いろいろな条件のコンパイルエラーとその対応方法について、広く記録することによって、いつか同じエラーに遭遇した時にやくに立つことを目指しています。
この半年の間で、三度、自分のネットでの記録に助けられたことがあります。
また過去に解決できなかった記録を１０種類以上、最近になって解決できたことがあります。それは、主に次の３つの情報に基づいています。
https://stackoverflow.com
https://cpprefjp.github.io
http://ja.cppreference.com/
また
https://researchmap.jp/joub9b3my-1797580/#_1797580
に記載したサイトのお世話になっています。
作業方針(sequence)
Clang++では-std=c++03, C++2bの2種類
g++では-std=c++03, c++2bの２種類
でコンパイルし、
１）コンパイルエラーを収集する。
２）コンパイルエラーをなくす方法を検討する。
コンパイルエラーになる例を示すだけが目的のコードは、コンパイルエラーをなくすのではなく、コンパイルエラーの種類を収集するだけにする。
文法を示すのが目的のコード場合に、コンパイルエラーをなくすのに手間がかかる場合は、順次作業します。
３）リンクエラーをなくす方法を検討する。
文法を示すのが目的のコード場合に、リンクエラーをなくすのに手間がかかる場合は、順次作業します。
４）意味のある出力を作る。
コンパイル、リンクが通っても、意味のある出力を示そうとすると、コンパイル・リンクエラーが出て収拾できそうにない場合がある。順次作業します。
１）だけのものから４）まで進んだものと色々ある状態です。一歩でも前に進むご助言をお待ちしています。「検討事項」の欄に現状を記録するようにしています。

template<class ... Types> struct Tuple { };
Tuple<> t0;
Tuple<int> t1;
Tuple<int, float> t2;
Tuple<0> error;
// Types contains no arguments
// Types contains one argument: int
// Types contains two arguments: int and float // error: 0 is not a type
// [Example 2:
template<class ... Types> void f(Types ... args);
f();
f(1);
f(2, 1.0);
// args contains no arguments
// args contains one argument: int
// args contains two arguments: int and double
// [Example 3:
template <typename... Args>
void foo(Args... args) {
[...xs=args] {
bar(xs...);
};
}
foo();
foo(1);
// xs is an init-capture pack
// xs contains zero init-captures // xs contains one init-capture
// [Example 4:
template<class ... Types> void f4(Types ... rest);
template<class ... Types> void g(Types ... rest) {
f4(&rest ...); // &rest ...is a pack expansion; &rest is its pattern
}
// [Example 5:
template<typename...> struct Tuple {};
template<typename T1, typename T2> struct Pair {};
template<class ... Args1> struct zip {
template<class ... Args2> struct with {
typedef Tuple<Pair<Args1, Args2> ... > type;

// OK, Args is expanded by the function parameter pack args // OK, “Args” and “args” are expanded
// error: pattern does not contain any packs
// error: pack “args” is not expanded
// OK, first “args” expanded within h, // second “args” expanded within f
// [Example 6:
template<typename ...Args>
bool all(Args ...args) {
return (... && args);
}
bool b = all(true, true, true, false);
// Within the instantiation of all, the returned expression expands to ((true && true) && true) && false, which evaluates to false.
// [Example 7:
template<class... T> struct X : T... { };
template<class... T> void f(T... values) {
X<T...> x(values...);
}
template void f7<>();
// OK, X<> has no base classes
