CppCast Episode 82: Catch 2 and C++ the Community with Phil Nash
Episode 81 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Phil Nash, Developer Advocate at JetBrains, to talk about updates to the Catch Unit test library and new features coming to CLion and ReSharper for C++.
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.
Path Exploration -- Adi Shavit
A short stroll along filesystem::path.
Path Exploration
by Adi Shavit
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...

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
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 constexpris 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...
