C++17's constexpr Lambda Support

by Jason Turner

About the show:

In this episode Jason demonstrates how C++17's support for lambdas in a constexpr context can clean up many constexpr use cases.

Simplifying templates and #ifdefs with if constexpr--Simon Brand

By Adrien Hamelin | Dec 12, 2016 02:55 PM | Tags: experimental basics

The new if constexpr will change a good part of our code for the better!

Simplifying templates and #ifdefs with if constexpr

by Simon Brand

From the article:

if constexpr is a C++17 feature which allows conditionally compiling code based on template parameters in a clear and minimal fashion. It is essentially an if statement where the branch is chosen at compile-time, and any not-taken branches are discarded without being instantiated...

Capturing perfectly-forwarded objects in lambdas -- Vittorio Romeo

Does [x = std::forward<decltype(x)>] behave like you expect?

capturing perfectly-forwarded objects in lambdas

by Vittorio Romeo

From the article:

Perfect forwarding and forwarding references allow developers to write generic template functions that retain the lvalueness/rvalueness of passed arguments [...] Let's try to use auto&&, std::forward and C++14's generalized lambda capture syntax to implement our desired semantics. [...] What we really want to do is:

• Capture by copy if a is an rvalue reference.
• Capture by reference if a is an lvalue reference.

[...]

Technical Debt - More Captureless Lambda Fun -- Adi Shavit

More interesting facts about captureless lambdas.

Technical Debt

by Adi Shavit

From the article:

The series on captureless lambdas generated some interesting comments.  
The articles discusses converting captureless lambdas into function pointers without explicitly specifying the cast-to type, calling conventions and standard conformance and a special callbackizing function for capturing lambdas.

The view from Nov 2016 C++ Standard Meeting Issaquah

By MichaelWong | Dec 9, 2016 10:33 AM | Tags: None

Hi all, I have been on airplanes for the last 10 weeks in a row, starting with CPPCON 2016 on September 16 2016. But first, I wanted to update everyone on the latest status of the C++ Standard meeting from Issaquah on Nov 7, 2016. Here is a blog post where you can see a video of what is coming for C++17 and download the slides. You can also see what happened in Issaquah for Evolution, Parallelism, Concurrency, and the latest status of the National Body Comments:

C++ 17 Transformation...--phantom

By Adrien Hamelin | Dec 7, 2016 11:48 AM | Tags: experimental basics

The transformation is only a beginning towards catching up from C++98, but it does show why modern C++ features improve your code.

C++ 17 Transformation...

by phantom

From the article:

I'm basically really bad at working on my own projects, but with the recent release of Visual Studio 2017 RC and its improved C++17 support I figured it was time to crack on again...

To that end I've spent a bit of time today updating my own basic windowing library to use C++17 features. Some of the things have been simple transforms such as converting 'typedef' to 'using', others have been more OCD satisfying...
