This is a simple C++ library that facilitates parsing command line arguments in a type independent manner.

cpplint is a command-line tool to check C/C++ files for style issues following Google’s C++ style guide. While Google maintains its own version of the tool, this is a fork that aims to be more responsive and make cpplint usable in wider contexts.

PlutoSVG is a compact and efficient SVG rendering library written in C. It is specifically designed for parsing and rendering SVG documents embedded in OpenType fonts, providing an optimal balance between speed and minimal memory usage. It is also suitable for rendering scalable icons.

This library is a C++17 cross-platform, single-header implementation of UUID, a 128-bit number used to uniquely identify information in computer systems, such as database table keys, COM interfaces, classes and type libraries, and many others.

This package provides a single-header implementation of C++20's std::span, conforming to the C++20 committee draft. It is compatible with C++11, but will use newer language features if they are available.

reproc (Redirected Process) is a C/C++ library that simplifies starting, stopping and communicating with external programs. The main use case is executing command line applications directly from C or C++ code and retrieving their output.

This package provides a C++ implementation of a hash map and a hash set which preserve the order of insertion. It is intended for efficient ordered insertions and lookup, while sacrifing performance for ordered erase operations.

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.

Lager is a library for value-oriented design implementing the unidirectional data-flow architecture. Apart from a store and various event loops it also provides lenses and cursors.

This package provides a C++ toolkit for making wayland GUI apps.

JUCE is a C++ application framework for creating applications including VST, VST3, AU, AUv3, AAX and LV2 audio plug-ins and plug-in hosts.

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.

Abseil is a collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's C++ code base.

Magic Enum offers static reflection of enums, with conversions to and from strings, iteration and related functionality.

gperftools is a collection of a high-performance multi-threaded malloc() implementation plus some thread-friendly performance analysis tools:

• tcmalloc,

• heap profiler,

• heap checker,

• CPU checker.

This package provides a simple argument parser for C++.

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

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.

debug_assert is a C++11 header-only library which provides the DEBUG_ASSERT() macro, which among other features can be selectively enabled in different parts of your code.

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 the official implementation for hypr configuration language used in Hyprland.

CodeSynthesis XSD (also known as libxsd or xsdcxx) is an XML Schema to C++ data binding compiler. Provided with an XML instance specification (XML Schema), it generates C++ classes that represent the given vocabulary as well as XML parsing and serialization code. The data stored in XML can then be accessed using types and functions that semantically correspond to an application domain rather than dealing with the intricacies of reading and writing XML.

This package provides a header-only implementation of std::variant (formerly boost::variant) for C++11/14.

cli is a domain-specific language (DSL) for defining command line interfaces of C++ programs. It allows you to describe the options that your program supports, their types, default values, and documentation.
