CXXIter: A chainable c++20 LINQ-like iterator library

• CXXIter

  3 36 0.0 C++

  Ergonomic C++ Iterator interface for STL containers

I thought it might be a nice opportunity to get to know C++20 in the process, so I first read up about the new features, and then started applying them to a little iterator library I call CXXIter... that then somehow ended up getting a little bigger and more ergonomic than I had expected. I took inspiration for functions and appearance from LINQ, as well as from Rust's iterators. CXXIter allows passing elements as references, as well as using moves to pass them through the iterator. I know that there already are a couple of these libraries - but what would programming be without a little NIH here and there? :)

• range-v3

  19 4,005 4.4 C++

  Range library for C++14/17/20, basis for C++20's std::ranges

[range-v3](https://github.com/ericniebler/range-v3) which std::ranges was based on has the `to>()` which as far as I know is expected to get into c++23 :)

Have you seen libflow? It's also built on the same model (Rust-style iterators), curious how they compare.

• fms_iterable

  3 3 6.0 C++

  iterators with explicit operator bool() const

Good stuff! I am a fan of LINQ and see you took pains to make your library performant (a common complaint against LINQ). My take on a more C++-y way of doing this is https://github.com/keithalewis/fms_iterable. An iterable is a C++ iterator with explicit operator bool() const to detect the end. The downside is I have to figure out how to translate this into the standard set of LINQ operators. Nowhere near as complete as your work but my main use case is implementing numerical algorithms. Maybe you'll find a pony in there. :-)

  LINQ for C++ (cpplinq) is an extensible C++11 library of higher-order functions for range manipulation. cpplinq draws inspiration from LINQ for C#.

How does it compare to https://github.com/mrange/cpplinq
