This package provides a header-only library to retrieve the file names of XDG base directories, such as XDG_CONFIG_HOME.

std::expected is proposed as the preferred way to represent objects which will either have an expected value, or an unexpected value giving information about why something failed. Unfortunately, chaining together many computations which may fail can be verbose, as error-checking code will be mixed in with the actual programming logic. This implementation provides a number of utilities to make coding with expected cleaner.

The AWS Common Runtime (CRT) library provides a C++ wrapper implementation for the following AWS C libraries: aws-c-auth, aws-c-cal, aws-c-common, aws-c-compression, aws-c-event-stream, aws-c-http, aws-c-io, aws-c-mqtt, aws-checksums, and s2n.

expected lite is a single-file header-only library for objects that either represent a valid value or an error that can be passed by value. It is intended for use with C++11 and later. The library is based on the std::expected proposal (http://wg21.link/p0323).

The AWS SDK for C++ provides a C++11 interface to the AWS API. AWS provides on-demand computing infrastructure and software services including database, analytic, and machine learning technologies.

This package provides simple property input/output utilities for C++.

RapidFuzz is a fast string matching library for Python and C++, which is using the string similarity calculations from FuzzyWuzzy.

tinyformat is a type-safe printf replacement library in a single C++ header file. Design goals include:

• Type-safety and extensibility for user defined types

• C99 printf compatibility, to the extent possible using std::ostream

• POSIX extension for positional arguments

• Simplicity and minimalism; a single header file to include and distribute with your projects

• Augment rather than replace the standard stream formatting mechanism

• C++98 support, with optional C++11 niceties

This package provides useful C++ classes and routines such as argument parser, IO and conversion utilities.

libconfini is an INI file parser library written in C. It focuses on standardization and parsing exactness and is at ease with almost every type of file containing key/value pairs.

This package provides a header-only C and C++ library for calculating integer division by using shift, add and multiply instructions.

cpptrace is a simple and portable C++ stacktrace library supporting C++11 and greater. In addition to providing access to stack traces, cpptrace also provides a mechanism for getting stacktraces from thrown exceptions for debugging and triaging.

The Clipper library performs line & polygon clipping - intersection, union, difference & exclusive-or, and line & polygon offsetting. The library is based on Vatti's clipping algorithm.Note: This package is a major update of the original clipper library.

Glaze is an in-memory JSON and reflection library for modern C++. It also provides support for BEVE, CBOR, CSV, MessagePack, TOML, YAML, and EETF.

IceCream-Cpp is a C++ library for printf debugging. It is inspired by the Python library of the same name.

frozen is a header-only library that provides zero cost initialization for immutable containers, fixed-size containers, and various algorithms. It provides features such as:

• immutable (also known as frozen), constexpr-compatible versions of std::set, std::unordered_set, std::map and std::unordered_map

• fixed-capacity, constinit-compatible versions of std::map and std::unordered_map with immutable, compile-time selected keys mapped to mutable values.

• zero cost initialization version of std::search for frozen needles using Boyer-Moore or Knuth-Morris-Pratt algorithms.

The unordered_* containers are guaranteed perfect (no hash collision) and the extra storage is linear with respect to the number of keys.

c2ffi is a tool for extracting definitions from C, C++, and Objective C headers for use with foreign function call interfaces. It uses the Clang/LLVM infrastructure to extract the data, and emits it in various formats, including json.

ringbuffer is a library containing a ringbuffer. It is lock-free (using atomics only), and allows multiple readers, but only one writer.

scn is a text parsing library for C++. It can be used as a safe alternative to scanf or as a fast alternative to IOStreams, analogous to fmt.

This package provides a collection of C++ libraries intended to be useful for building network-based applications.

This package contains a C++11 multiple-producer-multiple-consumer lockless queues header library based on circular buffer with std::atomic.

MPark.Variant provides the C++17 std::variant for C++11/14/17. It is based on the implementation of std::variant in libc++.

EEL2 is an expression evaluation library and realtime compiler based on AVS's EEL.

This package provides simple string utilities for C++.
