Boost.Static_views

Handy tools for manipulation of compile-time data.

StaticViews is a modern C++14/17 library that lets you easily manipulate constexpr homogeneous sequences using Ranges TS syntax. The main building block is a View, a non-owning container with random access to elements. These views can be used to access of modify your data, and can be used instead of iterators. Views are also easily composable which allows you to build constexpr computational pipelines with a readable syntax. On top of views, a static_map, a compile-time hash table, is built.

Getting started

The library has three modes of operation:

• In tree build as part of Boost.
• Standalone.
• Standalone single header.

To try out the standalone single-header just download the single-header/static_views.hpp file:

wget "https://raw.githubusercontent.com/BoostGSoC17/static-views/development/single-header/static_views.hpp"

and add it to your include path. Have a look at example/static_map.cpp to get started. Full documentation is available here.

Supported compilers

Strictly speaking, any compiler implementing C++14 should do. Currently, however, only Clang (4+) can compile Static_views. It seems that GCC has trouble with EBO (Empty Base Optimisation) which the library uses extensively. MSVC is a lost cause, I'm afraid.

TODOs

I am planning to propose this library for addition to Boost. After the second GSoC I think the implementation is more or less complete. There are probably lots of bugs that still need to be fixed, and I hope that after a bit of arguing GCC might agree to compile the code. The documentation still requires quite a bit of work though (the tutorial is vastly outdated).
