Judge me by my C++, not my WordPress
(Difficult-to-grok metaprogramming below. Not for the faint of heart.) At the recent Urbana-Champaign meeting of the C++ Standardization Committee, Bill Seymour presented his paper N4115: Searching for Types in Parameter Packs which, as its name suggests, describes a library facility Continue reading Tiny Metaprogramming Library
Frequent readers of this blog know that over the past year, I’ve been working on a modern range library suitable for standardization, integrating good ideas from hither and thither — particularly from Sean Parent and Andrew Sutton — resulting in Continue reading Ranges, Concepts, and the Future of the Standard Library
(Disclaimer: here be esoteric language wonkery. Abandon all hope.) If you read or write Generic-code-with-a-capitol-‘G’, you may have written or seen code like this: using std::swap; swap( a, b ); The first line brings std::swap into consideration, and the second Continue reading Customization Point Design in C++11 and Beyond
Eleven months ago, I began work on an updated range library for modern C++. Yesterday, I submitted a proposal to the C++ standardization committee to add ranges to the Standard Library. The proposal presents a vision for a future Standard Continue reading N4128: Ranges for the Standard Library
I’ve been hard at work fleshing out my range library and writing a proposal to get range support into the standard. That proposal describes a foundational range concept: Iterable. An Iterable is anything we can pass to std::begin() and std::end() Continue reading Ranges in C++: Counted Iterables and Efficiency
Here’s a simple question: in C++11 what’s the best way to put debug checks in constexpr functions? Since assert is not constexpr, the obvious doesn’t work: constexpr bool in_range(int val, int min, int max) { assert(min <= max); // OOPS, Continue reading Assert and Constexpr in C++11
The C++ community is suffering from the loss of the cpp-next.com website and all the great content that was once hosted there. In the past 2 months, I’ve gotten many questions both about the site and about the fate of Continue reading Cpp-Next.Com and the Expressive C++ Series
I’ve been busy since I last wrote about ranges. I have a lot of news to share, but in this post, I’m going to narrowly focus on a recent development that has me very excited. It’s a new feature that Continue reading Range Comprehensions
Last time, I introduced a new concept, Iterable, and showed how it solved many of the problems with pair-of-iterator-style ranges. This time around, I’m going to extend Iterable in small ways to make programming with infinite ranges safer and more Continue reading Range Concepts, Part 4 of 4: To Infinity And Beyond
In the last two blog posts, I describes the challenges I’ve encountered while building a next-generation range library. In this post, I’ll sketch for you my proposed solution: refinements of the range concepts that allow delimited, infinite, and pair-o’-iterator-style ranges Continue reading Range Concepts, Part 3 of 4: Introducing Iterables
