Summer 2023 WG21 in Varna, Bulgaria

Between the 12^th and 17^th  of June our Software Developer Jonathan Müller attended the ISO C++ standardization committee in Varna, Bulgaria. This was his first meeting since the pandemic and the first meeting as an official member thanks to think-cell's participation in the German national body. In total, 18 different countries sent representatives and over 180 C++ experts attended (although some of them only remotely).

Have a look at a part of his trip report below or read the full article here!

“I started the week on Monday in SG-9, the study group for ranges. Although we at think-cell have our own ranges library, we nevertheless want to integrate with the standard and re-use their facilities (if we don't have a better implementation). We are particularly interested in P2846 - std::ranges::size_hint by Corentin Jabot. Some ranges cannot provide an exact std::ranges::size, but an approximate size that is most likely correct. The paper mentions Unicode case folding (which mostly converts code points to other code points, but can also expand a single code point into multiple), but we would also use it for our formatting ranges, which e.g. convert integers to range of characters. With a facility that provides an approximate size, we can reserve memory in containers before appending the range; currently, we can only do that for sized ranges.”
