I'm announcing my first ever open-to-the public remote seminar:
C++ Best Practices - Tooling
eventbrite.com/e/c-best-pract
Early bird tickets available! March 8, 1.5 hrs
I hope to make training available to a larger group of people but in a way that works with my interactive style!

Support (Godbolt) folks!
We all rely on it directly or indirectly; it's an important piece of infrastructure our C++ community relies upon.
It's a huge amount of work to maintain, extend and host $ at scale.
Thank you & et al.

Constexpr contexts do not permit undefined behaviour. This can be used to our advantage to statically test our code, ensuring that the code does not contain UB. #cpp #coding #learnprogramming

I have built a clang-tidy tool that will report on *all* implicit conversions that *might* be problematic.
It's rather thorough.
I've tested it on one of my own projects, with interesting results.
Who would like to see their project tested with it in a live C++Weekly stream?

it's 2022, and C++23 on the way... but have a look at my heavily updated list of C++17 features:

Ok C++ Twitter!
You did an awesome job sharing all of your favorite closed source / for-pay tools last week.
That time, share your favorite OPEN SOURCE and/or FREE C++ development tools!
Let's help spread the word on these awesome tools!

💁♂️ C++ tip: While it's tempting to inline (or "= default") constructors and destructors in header files, putting them out-of-line instead often allows you to #include fewer things in these headers.
And you can still use "= default" out-of-line:
Foo::Foo() = default; 🤓👍

We need to discuss the difference between `static constexpr` and `inline constexpr` and when to use which.

Remember, *you* get a say in what topics are covered on C++ Weekly now!

Be sure to submit ideas, comment, and vote on existing plans.
I'm not going strictly 100% in order, but keeping pretty close to it!

That seems to be a really nifty tool for taking timing measurements. Haven't run into any issues so far. Statistical analysis across multiple runs, warmup, cache-clearing, outlier detection, parameterized benchmarks, etc.

Just found out that "/std:c++latest" is enough when using the latest MSVC versions and should of course be preferred over the macros defined in <ciso646>.

And for the Microsoft Visual Studio users: you need to include the <ciso646> header to be able to use "not", "and", "or", etc.

I recently started to use "not" (the alternative spelling of unary operator "!") in more and more boolean expressions. I have to admit that it really does make for more readable code. However, using "not_eq" instead of "!=" doesn't appeal to me at all.

A test of what people know and what people would prefer: Is this UB? Should this be UB?
- Yes UB; Should be UB39.2%
- Not UB; Should be UB11.1%
- Yes UB; Shouldn't be UB13.2%
- Not UB; Shouldn't be UB36.4%

same behavior if the first parameter is a string literal (const char*):

Show this thread
I would interpret the relevant section of the standard to mean that the above behavior must be a bug.

Show this thread
Can someone tell me if this highly intuitive behavior is intentional or a quirk of libstdc++'s ranges implementation?
Why on earth would you treat a const char* differently from a string_view here?
