coveo::linq

A C++ library implementing LINQ operators similar to .NET's, like select, where, etc.

TL;DR

#include <coveo/linq.h>
#include <iostream>

int main()
{
    const int FIRST[] = { 42, 23, 66, 13, 11, 7, 24, 10 };
    const int SECOND[] = { 67, 22, 13, 23, 41, 66, 6, 7, 10 };

    using namespace coveo::linq;

    auto is_even = [](int i) { return i % 2 == 0; };

    auto seq = from(FIRST)
             | intersect(SECOND)                    // Intersect both arrays
             | where([](int i) { return i != 13; }) // I'm supersticious, remove 13
             | order_by_descending(is_even)         // Place even numbers first
             | then_by([](int i) { return i; });    // Then sort numbers ascending

    std::cout << std::endl;
    for (auto&& elem : seq) {
        std::cout << elem << " ";
    }
    std::cout << std::endl;
    // Prints "10 66 7 23"

    return 0;
}

Installing

The library is header-only. Therefore, to add it to your project, simply copy the content of the lib directory to a suitable place in your structure and add that path to your include paths. Look at the test project/makefile for examples.

Compiler support

coveo::linq requires a C++ compiler that supports the C++11 standard. It has been successfully tested with the following compilers; YMMV.

• Microsoft Visual Studio 2015 Update 3
• GCC 5.4.1
• Clang 3.4
