[C++] 202 Visual C++におけるglob関数の代替方法

[Windows11, Visual C++17]

Visual C++ではPOSIX固有のglob関数が使えないため、std::filesystem::directory_iteratorを使用します。

ソースコード１つなのでコマンドプロンプトでコンパイル&ビルドしました。

#include <iostream>
#include <string>
#include <vector>
#include <filesystem>

int main()
{
	std::string dir_name = "D:\\code\\VC++\\mylib_vc\\src";
	std::vector<std::string> files;
	std::filesystem::path dir_path(dir_name);

	if (!std::filesystem::is_directory(dir_path)) {
		std::cout << "ディレクトリではありません" << std::endl;
		return -1;
	}
	auto dir = std::filesystem::directory_iterator(dir_path);
	for (auto& p : dir) {
		std::string pathname = p.path().string();
		std::cout << p.path().string() << std::endl;
		files.push_back(pathname); // リスト化して利用
	}
}
