A Tiny Metaprogramming Library: Extending the Metaphor, entering metafunctions

I know I’m repeating this everytime I write a new article, but it’s one of the key points to make template metaprogramming feasible, which means: TMP is just a functional language. A language with a “Aghhhh, my eyes, please!!! Aaahhhhhg!!!” syntax, but still a functional language.

To start a C++ metaprogramming library the right way, we’d better have a clear idea of what a metafunction is, and how our library represents and manages a metafunction.

A Tiny Metaprogramming Library

It seems people like template metaprogramming. After three successful blog posts about tmp – with 5k views on average each one – I’m sure people like and even want to understand that obscure corner of C++.

It’s not a funny way to play with the compiler only, template metaprogramming is a powerful tool for C++ developers and something that many of us must deal with everyday.

Metaprogramming with Modern C++: The Haskell Metaphor

I you are one of who have been following our post series about template metaprogramming with modern C++, at this time you should have become a C++ template Guru. At least thats what I expect ;).

You know about class templates, function templates, value parameters, type parameters, variadic templates… Your template metaprogramming toolbox is full of great things to play with. Thats good, but you want to start playing with your compiler, writting some cool metaprograms.

Lets start the game!

Template Metaprogramming with Modern C++: templates in depth

Template Metaprogramming with Modern C++: Templates in depth

The last time  we learnt what metaprogramming was, how metaprogramming in C++ via templates works, and the functional spirit of the embedded language that C++ template metaprogramming is.

In this post we will learn C++ templates in depth: Class and function templates, template parameters, variadic templates, all with in depth examples.
SPOILER: Finally, there is no SFINAE explanation on this post. This has a large amount of contents to be read and understood, I think understanding correctly the template system and the different categories of template parameters is good enough for a single (But large) blog post. Of course, if there is any problem feel free to post a comment here.
