Brigand is a light-weight, fully functional, instant-compile time C++ 11 meta-programming library.
Meta-programming libraries are extremely useful to library authors as they enable them to deliver more features with less code. They also find application in projects where performance and productivity are important.
Here are a couple of ideas:
- Create a tuple from a list of types and then transform it into a variant
- Look for the presence of a type in a tuple and get its index
- Sort a list of types
- Advanced static assertion with arithmetics and complex functions
- Go through a list of types and perform a runtime action for each type
- And much more
Long story short: everything you could do with Boost.MPL, you can do with Brigand, except it requires less code and compiles much faster.
Work in progress

- Simple, focused and powerful
- Supports a wide range of compilers and platforms, including the two latest release of Visual Studio
- Instant-compilation, no more excuse for getting an espresso!
Brigand requires a C++ 11 compiler.
Brigand is built and tested before each release against clang, gcc and Visual Studio. We have tested that Brigand currently supports:
- clang 3.4 and upward
- GCC 4.8 and upward
- Partial Visual Studio 2013 Update 4 support
- Visual Studio 2015 Update 3 and upward
- Visual Studio 2017
Brigand was born out of the need to replace the venerable, but aging, Boost.MPL in quasardb.
Because on all platforms we may not have a compiler capable of supporting Hana, and after reading Peter Dimov's Simple C++ 11 metaprogramming article (as well as Eric Niebler's Tiny Metaprogramming Library) I realized the amount of work to write a fully-functional MPL was manageable.
Joel told me that, at Numscale, they had exactly the same problem. Brigand was born.
Quel canaillou ce brigand.
