Text processing library
The text processing library includes components for dealing with text.
Contents
[edit] Localization library
The headers <locale> and <clocale> provide internationalization support for character classification and string collation, numeric, monetary, and date/time formatting and parsing, and message retrieval.
[edit] Regular expressions library (since C++11)
The header <regex> provides a class that represents regular expressions, which are a kind of mini-language used to perform pattern matching within strings.
[edit] Formatting library (since C++20)
The header <format> provides facilities for type-safe and extensible string formatting that is an alternative to the printf family of functions, and intended to complement the existing C++ I/O streams library.
[edit] Null-terminated sequence utilities
Null-terminated character sequences (NTCTS) are sequences of characters that are terminated by a null character (the value after value-initialization).
The strings library provides functions to create, inspect, and modify such sequences:
- null-terminated byte strings (NTBS) helper functions (including support of wide character types),
- null-terminated multibyte strings (NTMBS) helper functions.
[edit] Primitive numeric conversions (since C++17)
In addition to sophisticated locale-dependent parsers and formatters provided by the C++ I/O library, the C I/O library, C++ string converters, and C string converters, the header <charconv> provides light-weight, locale-independent, non-allocating, non-throwing parsers and formatters for arithmetic types.
