- What is `template for` in C++26? - Stack Overflow
template for is a new kind of loop called an expansion statement introduced in C++26 by P1306 Unlike all the other C++ loops, where the looping is based on some runtime condition, an expansion statement is a loop that happens entirely at compile time Rather than running the same code N times, the compound-statement is stamped out N times during compile time That is, each kind of expansion
- Why is std::is_trivial deprecated in C++26? - Stack Overflow
This change comes from P3247: Deprecate the notion of trivial types The problem with std::is_trivial is that it mixes two different checks: std::is_trivially_copyable std::is_trivially_default_constructible std::is_trivial is somewhat useless These two checks are used in different situations, so having them bunched together into a single trait isn't very useful For example, a container that
- Xcode 26. 4 build error: call to consteval function fmt::basic_format . . .
Fix for Xcode 26 4 C++20 build errors in React Native The new compiler in Xcode 26 4 changed how it handles C++20 features It’s now rejecting the way the older {fmt} library (included in React Native) validates strings at compile-time The easiest fix is to force the fmt library to use C++17 instead of C++20 Since consteval didn't exist in C++17, the compiler will stop complaining and
- Rosetta Simulator Run Destination not showing in Xcode 26

- C++26 Reflection - How to actually do class metaprogramming?
Now, when I read that C++26 has landed with reflections, I thought I could write something like the above But crucially, while one can now do metaprogramming on members with nonstatic_data_members_of, add annotations to them, and access members using [: :], I do not see how I can currently inject methods to a class, or generate aggregate initializers The closest I got with a quick draft
- How can I programmatically create a permanent admin in Keycloak 26. 1. 2 . . .
To grant an user full administrative privileges on both the master and a custom realm in Keycloak 26 1 2, you can leverage the fact that every realm in the master realm appears as a “client” with the name <realm name>-realm By assigning realm-management roles on that client to your permanent admin user, you effectively give them full control over the target realm Grant full “realm
