Implemented some convenient utility functions as an extension for C++ standard template library.
class AliasMethod in header alias_method.h. Using STL-like implementation, APIs are exactly corresponding to what in std::discrete_distribution.
Support C++11 or above.
See Darts, Dice, and Coins: Sampling from a Discrete Distribution for more information.
For container cont of type Container, if every element in it can be output via ostream operator, and cont itself is iterable (for C++17 or above const-iterable, which means std::cbegin(cont) and std::cend(cont) / std::begin(cont) and std::end(cont) is implemented).
Implemented using SFINAE, which means Substitution Failure Is Not An Error. By providing multiple possible overload but only one resolution is passed, we can use this overload resolution to avoid multiple function overloads which leads to compilation errors.
Currently, ostream operator for std::tuple, std::vector and other std-defined containers is valid.
Support C++11 or above except for array wrapper and reverse container wrapper.
- Array wrapper and reverse container wrapper require C++17 or above (since class template argument deduction requires C++17 or above)
Actually, in the beginning template partial specialization is used. However it cannot solve occasion when cv-qualifiers are involved, top-level and low-level of which is vexing. Also, pointer, reference of array is some kind of hard.
Using extension __PRETTY_FUNCTION__ of gcc and clang is a good idea. There's also a macro __FUNCSIG__ for MSVC, but I haven't explored it.
Simple character finding is ok. Macro from_type and from_var are provided.
Support C++11 or above.
On some occasions like graphics, a class may have many constructors which requires different number of arguments of the same types when compiling. Thus, it's necessary to avoid messed-up calling code burden. It's a simple idea yet, which requires further work.
