buckaroo 试用

我系统是mac 所以选择的是mac 的版本，官方是支持跨平台的。

安装

mac 版本安装

wget https://github.com/LoopPerfect/buckaroo/releases/download/v2.0.0/buckaroo-macos -O buckaroo
chmod +x ./buckaroo

取消信息收集（可选）

因为默认buckaroo 包含了遥测功能，在第一次运行的时候会有一个uuid生成，以此进行用户信息的统计，
我们可以通过环境变量禁用

export BUCKAROO_TELEMETRY_OPT_OUT=1

安装buck

因为buckaroo 使用了buck 做为包格式以及进行系统构建

brew tap facebook/fb
brew install buck

或者

wget https://github.com/njlr/buck-warp/releases/download/v0.3.0/buck-2019.01.10.01-osx -O buck
chmod +x ./buck
./buck

快速使用

这个来自官方的wiki，前提条件是参考上边的安装了buckaroo 以及buck

int main() {
  auto const xs = std::vector<int>({ 1, 2, 3, 4, 5 });
  auto const ys = xs
    | ranges::view::transform([](auto x) { return x * x; })
    | ranges::to_vector;

  for (auto const& i : ys) {
    std::cout << i << std::endl;
  }

  return 0;
}
