Range library for C++11/14/17. This code is the basis of a formal proposal to add range support to the C++ standard library.
Why does C++ need another range library? Simply put, the existing solutions haven't kept up with the rapid evolution of C++. Range v3 is a library for the future C++. Not only does it work well with today's C++ -- move semantics, lambdas, automatically deduced types and all -- it also anticipates tomorrow's C++ with Concepts.
Range v3 forms the basis of a proposal to add range support to the standard library (N4128: Ranges for the Standard Library). It also will be the reference implementation for an upcoming Technical Specification. These are the first steps toward turning ranges into an international standard.

Most of the source code in this project are mine, and those are under the Boost Software License. Parts are taken from Alex Stepanov's Elements of Programming, Howard Hinnant's libc++, and from the SGI STL. Please see the attached LICENSE file and the CREDITS file for the licensing and acknowledgments.
The code is known to work on the following compilers:
- clang 3.5.2
- GCC 4.8.5 (C++14 support requires GCC 5.2; C++14 "extended constexpr" support is poor before 6.1.)
Development Status: This code is fairly stable, well-tested, and suitable for casual use, although currently lacking documentation. No promise is made about support or long-term stability. This code will evolve without regard to backwards compatibility.
Build status (on Travis-CI):
I do this work because I love it and because I love C++ and want it to be as excellent as I know it can be.
