CPP23 - C++ 23

Library Features

Compile-time Support

`, various `` functions, and integral overloads of `std::to_chars` and `std::from_chars`. Metaprogramming utilities have been expanded with new type traits like `std::is_scoped_enum` and improvements to support move-only types in comparison concepts【6†source】.

C++23 introduces new range conversion functions, such as `std::ranges::to`, and a suite of constrained ranges algorithms, including `std::ranges::starts_with` and `std::ranges::ends_with`. New range adaptors like `std::views::zip` and `std::views::adjacent` enhance the flexibility of working with ranges【6†source】.

Enhancements in memory management include the introduction of `std::out_ptr` and `std::inout_ptr` for C interoperability and the `allocate_at_least` function for more efficient memory allocation strategies【6†source】【7†source】.

C++23 makes significant improvements in string manipulation and text processing, including new member functions for strings and views, and enhancements in formatting capabilities【6†source】.

The introduction of the stacktrace library provides developers with powerful tools for diagnosing and understanding program execution and errors【6†source】.

New formatted output functions `std::print` and `std::println` have been added to simplify common I/O operations, alongside improvements in stream handling and manipulation【6†source】.

The update includes new container types like flat set and flat map, improvements in container constructability and assignability from ranges, and enhancements to existing containers for better performance and usability【6†source】.

C++23 adds a new header `` to improve compatibility with C code, particularly in the area of atomic operations【6†source】.

Numerous defect reports have been addressed in C++23, covering a wide range of issues from identifier syntax to lambda expressions and comparison operators. This effort helps to refine the language and ensure its robustness【6†source】.

Similar to language defects, library defect reports have been addressed, focusing on the ranges library, input range adaptors, and various other standard library components【6†source】.

Monadic operations for `std::optional` and `std::expected` introduce a more functional programming style, allowing for chaining operations in a concise and expressive manner【6†source】.

Utility functions such as `std::to_underlying` for extracting the underlying value of enums and `std::move_only_function` for move-only callable wrappers enhance the language's utility and flexibility【6†source】.

`constexpr` enhancements extend to `std::bitset`, `std::unique_ptr`, and some `` functions, allowing more computations to be performed at compile time【6†source】.

New algorithms and adaptors for ranges, including `std::ranges::find_last` and `std::views::join_with`, increase the power and expressiveness of range-based programming【6†source】.

The introduction of `std::allocate_at_least` and updates to the `std::allocator` interface reflect a continued focus on improving memory management in C++【6†source】【7†source】.

Improvements to string processing include new functionalities for `std::basic_string` and `std::basic_string_view`, such as disabling construction from `nullptr` and introducing explicit range constructors【6†source】.

Enhancements in formatting and I/O include new capabilities for formatting ranges, tuples, and other types, as well as introducing easier ways to perform formatted output【6†source】.
