CppCast Episode 82: Catch 2 and C++ the Community with Phil Nash

by Rob Irving and Jason Turner

About the interviewee:

Phil started coding back in the early 80s, on 8-bit home computers: from the ZX-81 to the Commodore 64, in BASIC and assembler. He later moved on to PCs and C++ in the early 90s and, despite forays into other languages, keeps coming back to C++. His career has taken him through domains such as anti-virus, mobile, finance and developer tools - among others. He's the original author of the C++ test framework, Catch and is now Developer Advocate at JetBrains for CLion, AppCode and ReSharper C++. His hobbies include writing podcast bios and trolling the podcast hosts.

A short stroll along filesystem::path.

From the article:

The “experimental” Filesystem TS has been with us for a few years living in the std::experiment namespace. With C++17 it will finally be merged into std.

Please declare your variables as const -- Bartlomiej Filipek

Another explanation why const is a really powerful tool.

Please declare your variables as const

by Bartlomiej Filipek

From the article:

When using const the resulting code will be more verbose, explicit, cleaner (with probably smaller functions) and safer. Not to mention that you’ll get additional help from the compiler.

When noexcept?--Edouard of quasardb

A good question with a good answer.

When noexcept?

by Edouard of quasardb

From the article:

In a previous post, we had a look at the new constexpr keyword that has been introduced in C++ 11. Today we'll study another new fancy specifier: noexcept...

Episode 41 of C++ Weekly.

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

By Vittorio Romeo | Dec 12, 2016 05:32 AM | Tags: c++14 advanced

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

By Adi | Dec 12, 2016 05:16 AM | Tags: c++14 advanced

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:
