New video on the CopperSpice YouTube Channel:
Regular Expressions
by Barbara Geller and Ansel Sermersheim
About the video:
This video covers Regular Expressions, what they are and when you might want to use them. We also discuss when to avoid using a regex. We cover existing regex libraries that can be used in C++, briefly examine their pros and cons, and present the CopperSpice regular expression implementation.

LLVM 6.0.0 and Clang 6.0.0 are now available.
Clang 6.0.0 Release Notes
From the announcement:
Clang’s default C++ dialect is now gnu++14 instead of gnu++98. This means Clang will by default accept code using features from C++14 and conforming GNU extensions. Projects incompatible with C++14 can add -std=gnu++98 to their build settings to restore the previous behaviour.
Added support for some features from the C++ standard after C++17 (provisionally known as C++2a but expected to be C++20). This support can be enabled with the -std=c++2a flag. This enables:
A warning has been added for a <= token followed immediately by a > character. Code containing such constructs will change meaning in C++2a due to the addition of the <=> operator.
Clang implements the “destroying operator delete” feature described in C++ committee paper P0722R1 <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0722r1.html>, which is targeting inclusion in C++2a but has not yet been voted into the C++ working draft. Support for this feature is enabled by the presence of the standard library type std::destroying_delete_t.

From last Monday through this Monday, we ran our first global C++ developer survey.
Thank you to the over 3,200 of you who responded. As promised, here is a public summary of the results:
Results summary: C++ Developer Survey "Lite": 2018-02
This summary has now been forwarded to the C++ standards committee, along with the full text of your write-in answers (over 300 pages!). Your feedback will be very helpful, and has already started to be referred to by standards participants as we prepare for next week's ISO meeting in Jacksonville, FL, USA.
Thank you again for your participation. It is very helpful, and based on the success of this survey we plan to run it again in the future from time to time. When we do, it will be announced here on isocpp.org.
Note: Due to a SurveyMonkey bug, the word clouds showing popular keywords for the five open-ended questions cover about half the responses, which fortunately is still a large sample. They're working on a fix to include all the responses in the word clouds.

Presentation of a technique that enables transparent interception of the selected arguments passed to any function by means of a user-provided predicate metafunction.
Selective argument application
by Krzysztof Ostrowski
From the article:
Presentation of a design of an interceptor abstraction built over C++17 utilities that records values of the selected arguments passed to any action transparently, then applies that action to the captured arguments, and eventually passes the result value to the next action.

Matt Aubury philosophizes about digging a grave for certain std::index_sequence idioms.
RIP index_sequence, 2014–2017
by Matt Aubury
From the article:
std::tuple was one of the great additions to C++11. Whilst sometimes abused by lazy programmers (who should really be using a struct or class), it’s true value is as a container of arbitrary values in variadic templates.
Sadly, static typing makes working with tuples much harder in C++ than in most languages [...]

A brief tour into the realm of writing C and C++ applications, the role of the Standard Library and how it is implemented in various operating systems.
What are the C and C++ Standard Libraries?
By Triangles @ Internal Pointers
From the article:
I have been playing around with C++ for a while and one thing that always got me confused in the beginning was its anatomy: where do the core functions and classes I'm using come from? Who invented them? Are they packaged somewhere in my system? Is there a kind of official C++ manual around?

Now our articles have every chance to become even more interesting because PVS-Studio can now check the code of embedded devices. We have added support for a few ARM compilers, which I talk about in detail below.
Static Code Analyzer PVS-Studio 6.22 Now Supports ARM Compilers (Keil, IAR)
by Andrey Karpov
From the article:
I find the RT-Thread operating system a perfect candidate to be the first embedded system checked with PVS-Studio. I glanced through the analysis report by PVS-Studio and picked 95 warnings that I thought to be the most interesting ones. Too see all those messages for yourself, download the rt-thread-html-log.zip archive with the full HTML report. We introduced this format not so long ago, and some users may not know about it. So, I'd like to use this opportunity to explain it once again.

JetBrains considers embedded dev market a priority for C++ tools (especially CLion) and a very interesting direction for Kotlin/Native. However, before diving into it we are running a full-blown market research study.
Embedded developers survey

About the survey
This survey is a part of these research activities. Tell us how you do embedded development, what tools you use, what your needs and pains points are, and how we can help.
