QuickJS is a small and embeddable Javascript engine. It supports the ES2020 specification, including modules, asynchronous generators, proxies and BigInt.

Polylib is a free C library for doing computations on polyhedra. The library is operating on objects like vectors, matrices, lattices, polyhedra, Z-polyhedra, unions of polyhedra and other intermediary structures. It provides functions for all important operations on these structures. This package provides the version for operations on long integers.

The POCO C++ Libraries are a collection of open source C++ class libraries that simplify and accelerate the development of network-centric, portable applications in C++. The libraries integrate perfectly with the C++ Standard Library and fill many of the functional gaps left open by it.

Clang-format is both a library and a stand-alone tool with the goal of automatically reformatting C++ sources files according to configurable style guides. To do so, clang-format uses Clang's Lexer to transform an input file into a token stream and then changes all the whitespace around those tokens. The goal is for clang-format to both serve both as a user tool (ideally with powerful IDE integrations) and part of other refactoring tools, e.g. to do a reformatting of all the lines changed during a renaming.

System X.509 handling for accessing operating system dependents store and other storage methods. This is meant to be a portable way of finding and accessing the system X.509 certificate store.

UFL (Unified Form Language) is a unified language for definition of variational forms intended for finite element discretization. More precisely, it defines a fixed interface for choosing finite element spaces and defining expressions for weak forms in a notation close to mathematical notation. The form compilers FFC and SyFi use UFL as their end-user interface, producing UFC implementations as their output.
