MFront is a code generator which translates a set of closely related domain specific languages into plain C++ on top of the TFEL library.

This package provides a simple gettext replacement that works directly on .po files and doesn't need .mo files pre-generated.

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.

Zug is a C++ library providing transducers, that is, composable sequential transformations.

cpp-mustache is a Mustache implementation for C++ 11 and above. It is header only and has zero dependencies. It provides a templated string type for compatibility with any STL-like string (std::string, std::wstring, etc).

RTTR stands for Run Time Type Reflection. It describes the ability of a computer program to introspect and modify an object at runtime. It is also the name of the library itself, which is written in C++.

LunaSVG is an SVG rendering library in C++, designed to be lightweight and portable, offering efficient rendering and manipulation of Scalable Vector Graphics (SVG) files.

mcpp is Matsui's CPP implementation precisely conformed to standards.

Optional lite is a single-file header-only library to represent optional (nullable) objects and pass them by value. The library aims to provide a C++17-like optional for use with C++98 and later. If available, std::optional is used.

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.

This package provides a simple S-Expression parser for C++.

Pystring is a collection of C++ functions which match the interface and behavior of Python's string class methods using std::string. Implemented in C++, it does not require or make use of a python interpreter. It provides convenience and familiarity for common string operations not included in the standard C++ library. It's also useful in environments where both C++ and Python are used.

This package contains an implementation of the parallel external-memory suffix array construction algorithm called pSAscan. The algorithm is based on the sequential external-memory suffix array construction algorithm called SAscan.

This library provides a header-only unordered set and map data structures for C++.

SObjectizer is a cross-platform "actor frameworks" for C++. SObjectizer supports not only the Actor Model but also the Publish-Subscribe Model and CSP-like channels. The goal of SObjectizer is to simplify development of concurrent and multithreaded applications in C++.

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.

Functional Terminal (X) User interface (FTXUI) is a simple C++ library for terminal based user interfaces.

Main features:

• Functional style.

• Keyboard & mouse navigation.

• Support for UTF8 and fullwidth chars.

• Support for animations.

• Support for drawing.

• No dependencies.

This package provides the official implementation for hypr configuration language used in Hyprland.

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.

Taskflow is a C++ library for writing parallel and heterogeneous task programs.

Fifo_map is a C++ header only library for associative container which uses the order in which keys were inserted to the container as ordering relation.

fast_float is a header-only C++ library for parsing floating point numbers from strings. It implements the C++ from_chars functions for the float and double types.

libcutl is a C++ utility library. It contains a collection of generic and independent components such as meta-programming tests, smart pointers, containers, compiler building blocks, etc.
