This implements the struct `__format_arg_store` and its dependencies: * the class basic_format_arg, * the class basic_format_args, * the class basic_format_context, * the function make_format_args, * the function wmake_format_args, * the function visit_format_arg, * several Standard required typedefs. The following parts will be implemented in a later patch: * the child class `basic_format_arg::handle`, * the function `basic_format_arg::basic_format_arg(const T* p)`. The following extension has been implemented: * the class basic_format_arg supports `__[u]int128_t` on platform where libc++ supports 128 bit integrals. Implements parts of: * P0645 Text Formatting Completes: * LWG3371 visit_format_arg and make_format_args are not hidden friends * LWG3542 basic_format_arg mishandles basic_string_view with custom traits Note https://mordante.github.io/blog/2021/06/05/format.html gives a bit more information about the goals and non-goals of this initial patch series.

Overview
|
|
========
|
|
|
|
This document contains the status of the C++20 Format library in libc++. It is used to
|
|
track both the status of the sub-projects of the Format library and who is assigned to
|
|
these sub-projects. This is imperative to effective implementation so that work is not
|
|
duplicated and implementors are not blocked by each other.
|
|
|
|
|
|
If you are interested in contributing to the libc++ Format library, please send
|
|
a message to the #libcxx channel in the LLVM discord. Please *do not* start
|
|
working on any of the assigned items below.
