How and why overloading, templates, and auto deduction were invented? -- Milad Kahsari

By Milad Kahsari Alhadi | Jan 23, 2020 02:05 AM | Tags: None

Are you a student and wanted to know How and why overloading, templates, and auto deduction WERE invented? read the following article.

How and why overloading, templates, and auto deduction invented?

by Milad Kahsari

From the article:

Why we need the template function/classes and how this concept created by C++ compiler engineers? In this medium post, I want to go through the steps which made c++ experts think about the template concept and auto in the modern days of software development.

C++ - Initialization of Static Variables--Pablo Arias

A good summary.

C++ - Initialization of Static Variables

by Pablo Arias

From the article:

You are probably reading this because you code in C++. This means that you have battled frustration mastering auto deduction rules or lost your sanity trying to understand why std::initializer_list was considered a good idea. Anyone who has been doing this long enough knows that variable initialization is everything but trivial. It’s a problem too essential to ignore but too challenging to master. Today I’m here to tell you that there is more to it...

Madrid C++: C++ and WebAssembly

New C and C++ meetup in Madrid. Thursday the 30th at Liferay's HQ.

How to accelerate a website with C++ and WebAssembly (Spanish)

with Juan Morales and Miguel Cantón

In order to reduce latency, costs and gain scalability we decided to perform data analysis with Graphext using WebAssembly in the browser. We will talk about how to use emscripten to compile a C++ project to make it portable on all browsers.

2 Lines Of Code and 3 C++17 Features - The overload Pattern--Bartlomiej Filipek

2 Lines Of Code and 3 C++17 Features - The overload Pattern

by Bartlomiej Filipek

From the article:

While I was doing research for my book and blog posts about C++17 several times I stumbled upon this pattern for visitation of std::variant:

template<class... Ts> struct overload : Ts... { using Ts::operator()...; };
template<class... Ts> overload(Ts...) -> overload<Ts...>;

With the above pattern, you can provide separate lambdas “in-place” for visitation.

It’s just two lines of compact C++ code, but it packs a few interesting concepts.

Let’s see how this thing works and go through the three new C++17 features that make this patter possible...

Why were abbrev. lambdas rejected?--Barry Revzin

By Adrien Hamelin | Jan 20, 2020 11:29 AM | Tags: community

Did you know about the proposal?

Why were abbrev. lambdas rejected?

by Barry Revzin

From the article:

In November, 2017, I presented my proposal for abbreviated lambdas (P0573R2) to Evolution in Albuquerque. It was rejected (6-17), though the group was willing to consider future proposals for shorter lambdas which present new technical information (18-2).

Since then, there’s been a lot of confusion about what actually happened and why it was rejected, and part of this was my fault for not doing a good job communicating this to interested parties. Actually, that’s generous - I didn’t really communicate anything. So here is my making up for lost time by actually conveying this information...
