long_description="""pybind11 is a lightweight header-only library that
|
||||
exposes C++ types in Python and vice versa, mainly to create Python bindings of
|
||||
existing C++ code. Its goals and syntax are similar to the excellent
|
||||
Boost.Python by David Abrahams: to minimize boilerplate code in traditional
|
||||
extension modules by inferring type information using compile-time
|
||||
introspection.

|
||||
|
||||
The main issue with Boost.Python-and the reason for creating such a similar
|
||||
project-is Boost. Boost is an enormously large and complex suite of utility
|
||||
libraries that works with almost every C++ compiler in existence. This
|
||||
compatibility has its cost: arcane template tricks and workarounds are
|
||||
necessary to support the oldest and buggiest of compiler specimens. Now that
|
||||
C++11-compatible compilers are widely available, this heavy machinery has
|
||||
become an excessively large and unnecessary dependency.
|
||||
|
||||
Think of this library as a tiny self-contained version of Boost.Python with
|
||||
everything stripped away that isn't relevant for binding generation. Without
|
||||
comments, the core header files only require ~4K lines of code and depend on
|
||||
Python (2.7 or 3.x, or PyPy2.7 >= 5.7) and the C++ standard library. This
|
||||
compact implementation was possible thanks to some of the new C++11 language
|
||||
features (specifically: tuples, lambda functions and variadic templates). Since
|
||||
its creation, this library has grown beyond Boost.Python in many ways, leading
|
||||
to dramatically simpler binding code in many common situations.""")
