• tcmalloc,

• heap profiler,

• heap checker,

• CPU checker.

The C++ Actor Framework (CAF) offers a high-level C++17 programming environment using the actor model for concurrent, distributed computation.

Dashel is a data stream helper encapsulation C++ library. It provides a unified access to TCP/UDP sockets, serial ports, console, and files streams. It also allows a server application to wait for any activity on any combination of these streams.

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.

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.

lexy is a parser combinator library for C++17 and later.

This package provides the default libSwell.colortheme file for programs that use swell.

json_dto library is a small header-only helper for converting data between JSON representation and C++ structs. DTO stands for data transfer object.

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++.

This package provides a single-header C++11 library for computing Fast Fourier transformations. It supports multidimensional arrays, different floating point sizes and complex transformations.

This package implements a generic template for extended width signed and unsigned integral types. Up to 63 limbs of any built-in integer type are supported, and can be used to build powers of two like int128_t, uint256_t, but also somewhat esoteric types such as int24_t, uint80_t, or uint1536_t. The provided types can be used in much the same way as basic integer types.

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.

This package provides a Python library named _jsonnet which can evaluate Jsonnet files and expressions.

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.

Range-v3 is an extension of the Standard Template Library that makes its iterators and algorithms more powerful by making them composable. Unlike other range-like solutions which, seek to do away with iterators, in range-v3 ranges are an abstraction layer on top of iterators.

type_safe is a C++ header-only library which provides abstractions for defining more appropriate types, thus allowing C++'s type system to prevent more bugs.

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

CastXML is a C-family abstract syntax tree XML output tool. This project is maintained by Kitware in support of ITK, the Insight Segmentation and Registration Toolkit.

The simdjson library uses commonly available SIMD instructions and microparallel algorithms to implement a strict JSON parser with UTF-8 validation.

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.

This package provides a single-header C++14 library for saving and loading C++ objects using a binary format.

Immer is a library of persistent and immutable data structures written in C++.

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++.

Ada is a fast and spec-compliant URL parser written in C++. Specification for URL parser can be found from the WHATWG website.
