A fast & densely stored hashmap and hashset based on robin-hood backward shift deletion for C++17 and later.

The classes ankerl::unordered_dense::map and ankerl::unordered_dense::set are (almost) drop-in replacements of std::unordered_map and std::unordered_set. While they don't have as strong iterator / reference stability guarantees, they are typically much faster. Additionally, there are ankerl::unordered_dense::segmented_map and ankerl::unordered_dense::segmented_set with lower peak memory usage, and stable references (iterators are NOT stable) on insert.

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 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.

libcppgenerate is a library for generating C++ code from C++.

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 header-only C++ library to parse command line options. It supports the short and long option formats of getopt(), getopt_long() and getopt_long_only().

Hyprgraphics is a small C++ library with graphics/resource related utilities used across the hypr* ecosystem.

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.

sajson is an in-place JSON parser with support for parsing with only a single memory allocation.

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

sajson is an in-place JSON parser with support for parsing with only a single memory allocation.

This package provides header-only TOML config file parser and serializer for C++17.

Those tools are meant to be used by solver developers to e.g. load MFront behaviours from external shared libraries and retrieve all relevant meta data function.

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.

nlohmann::json is a C++ JSON library that provides intuitive syntax and trivial integration.

SafeInt is a class library for C++ that manages integer overflows. It also includes a C library that checks casting, multiplication, division, addition and subtraction for all combinations of signed and unsigned 32-bit and 64-bit integers.

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

xtl is a C++ header-only template library providing basic tools (containers, algorithms) used by other QuantStack packages.

ccls is a server implementing the Language Server Protocol (LSP) for C, C++ and Objective-C languages. It uses clang to perform static code analysis and supports cross references, hierarchies, completion and syntax highlighting. ccls is derived from cquery which is not maintained anymore.

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.

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

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

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.

SWELL is a Windows emulation Layer. It provides a set of common APIs, common controls and win32-style extensions.
