Pipelines for Modern C++

Getting Started

pipeline is a C++17 header-only template library that lets you setup data processsing pipelines. Simply include <pipeline/pipeline.hpp> and you're good to go. There is also a single_include version in single_include/.

Let's start with the simple pipeline below. Wrap your functions using pipeline::fn and create a pipeline using the pipe (|) operator. Then simply call the pipeline to execute a sequence of functions.

#include <iostream>
#include <pipeline/pipeline.hpp>
using namespace pipeline;

int main() {
  auto add_2 = fn([](auto a, auto b) { return a + b; });
  auto print = fn([](auto result) { std::cout << result << "\n"; });
  
  auto pipeline = add_2 | print;
  
  pipeline(2, 3); // 5
}
