- Reposted by Special Interest Group on C++Since I'm at 500+ followers, I'll share this again. If you're an academic who needs fast running computer code, but don't want to deal with the complexities of C++, this is for you! If I can get sufficient funding, I can create *little* languages for your domain. www.youtube.com/watch?v=zngT...

- Reposted by Special Interest Group on C++#Pedantry: It is function-name overloading; not function overloading. Function name is same across functions but each call resolves to a specific function based on fn. args. So, what is overloaded is function name. Granted, "function overloading" is easier to say. #cpp #java #programming #eduSky
- Reposted by Special Interest Group on C++Discuss: Change t only if it is not v; return true if t is changed. //1 return t == v ? false : (t = v, true); //2 if(t == v) return false; t = v; return true; sigcpp.godbolt.org/z/7MhT81nGG #cpp #eduSky

- Reposted by Special Interest Group on C++I expect ~2 hrs to make a reducer for this GCC bug, an hour+ to draft a report, and an hour to polish the reducer & report for filing. That is 5-6 hours to report a bug, on top of the 12 hours already spent. But that is the cost of using #FOSS and hopefully also a contribution that benefits others.
- Reposted by Special Interest Group on C++Template template parameter. A feature that keeps on giving bugs. In compilers. #cpp
- Reposted by Special Interest Group on C++The average C++ pgmmer needs -fexplain-ctad compiler option, a la EXPLAIN in RDBMSs. That and explainers with simpler accessible examples. Without those, it is virtually impossible for us average #cpp pgmmers to figure out CTAD with user-defined deduction guides applied to alias templates and such.

- Reposted by Special Interest Group on C++P0645 is the text-formatting proposal. An excellent read where Victor Zverovich (@ viz bsk .social) does a great job of pulling together many different ideas: www.open-std.org/jtc1/sc22/wg... format_to_n first appears in R4 of proposal; vformat_to_n does not appear anywhere but hope was discussed.

- Reposted by Special Interest Group on C++The design rationale for Boost Geometry is must-read for every #cpp pgmmer interested in metaprogramming. And a great assignment for graduate SW eng. classes. Most students (and profs for that matter) won't know enough C++ to appreciate the detail, but still. #eduSky www.boost.org/doc/libs/1_8...
- Reposted by Special Interest Group on C++C++ template pgmming can end up promoting macros because too much template boiler plate, esp. member function templates in class templates. E.g., a macro reducing 5 lines of boiler plate to one. Macro is used 8 times greatly improving readability compared to the noisy recurring boiler plate. #cpp

- Reposted by Special Interest Group on C++As Jason Turner says "constexpr all the things": Otherwise same, exe sizes when variables are not constexpr vs when they're constexpr: latter is only 27% of former's size. constexpr is easily one of the top additions to C++. Kudos to all involved: conception through enhancements. 👏 #cpp #eduSky
- Reposted by Special Interest Group on C++C++ std library has both std::format_to and std::format_to_n, but defines only std::vformat_to. I'm curious about the reasons to omit std::vformat_to_n. Asked on Mastodon. Apparently the fn. was deemed "not important enough to be in the public API" mastodon.social/@vitaut/1125... #cpp #question

- Reposted by Special Interest Group on C++GCC compiler messages for C++ are more/quite useful now, once you fish them out of the template vomit. Fishing is still a requirement though. #cpp #GCC

- Reposted by Special Interest Group on C++I just wrote a C++ function with uninitialized variables whose values are defined by non-trivial logic that follows. Justified, yet I feel like a criminal. But that's how rare uninitialized variables should be. PS: Am aware of lambdas, structured bindings, pair #cpp #softwareEngineering #eduSky
- Unwinding concept std::same_as up to std::integral_constant. Compilation of possible implementations from cppreference. Hope seeing it all together at once helps appreciate the behind-the-scenes. PS: read the code bottom to top; usable with no includes sigcpp.godbolt.org/z/nx6Y3sfvo #cpp #eduSky

- Reposted by Special Interest Group on C++I wish C++ allowed concept definitions in class scope, not just namespace scope. DRY, better encapsulate class, reduce litter outside class. E.g., if a class has many functions w "strict bool" parameter: 1. No litter outside but not DRY 2. DRY but concept visible outside class #cpp #eduSky
