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

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 provides a collection of C++ libraries intended to be useful for building network-based applications.

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

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.

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

This package provides a library that portably invokes native file open, folder select and file save dialogs. It allows the specification of a default file name and location, as well as filters with friendly names (such as "source files" or "image files") where supported.

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.

Kokkos-fft is an experimental FFT interface for the Kokkos C++ environment. It implements local interfaces between Kokkos and FFT libraries such as FFTW, cufft, hipfft (rocfft), and oneMKL. "Local" means not using MPI, or running within a single MPI process without knowing about MPI.

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.

Folly (acronymed loosely after Facebook Open Source Library) is a library of C++14 components that complements std and Boost.

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.

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.

CLI11 is a command line parser for C++11 and beyond that provides a rich feature set with a simple and intuitive interface.

This package provides header only C++ binary serialization library. It is designed around the networking requirements for real-time data delivery, especially for games.

GNU Cppi processes C source code files to properly indent the preprocessor directives to reflect their nesting. It also performs other standardizations, such as correcting the number of spaces between directives and the text following them.

This package arranges data by a set of methods. It uses rearrangers to reorder data points and mutators to change their values. From basic utilities, to centering the greatest value, to swirling in 3-dimensional space, rearrr enables creativity when plotting and experimenting with data.

Learn vector representations of words by continuous bag of words and skip-gram implementations of the word2vec algorithm. The techniques are detailed in the paper "Distributed Representations of Words and Phrases and their Compositionality" by Mikolov et al. (2013), available at <arXiv:1310.4546>.

This package provides functions for reading, writing, plotting, and manipulating phylogenetic trees, analyses of comparative data in a phylogenetic framework, ancestral character analyses, analyses of diversification and macroevolution, computing distances from DNA sequences, and several other tools.

This package performs projection predictive feature selection for generalized linear models and generalized linear and additive multilevel models. The package is compatible with the rstanarm and brms packages, but other reference models can also be used. See the package vignette for more information and examples.

The r-nleqslv package solves a system of nonlinear equations using a Broyden or a Newton method with a choice of global strategies such as line search and trust region. There are options for using a numerical or user supplied Jacobian, for specifying a banded numerical Jacobian and for allowing a singular or ill-conditioned Jacobian.

This package provides tools for visualizing, smoothing and comparing receiver operating characteristic (ROC curves). The area under the curve (AUC) can be compared with statistical tests based on U-statistics or bootstrap. Confidence intervals can be computed for (p)AUC or ROC curves.

This package provides tools for data importation, recoding, and inspection. There are functions to create new project folders, R code templates, create uniquely named output directories, and to quickly obtain a visual summary for each variable in a data frame. The main feature here is the systematic implementation of the "variable key" framework for data importation and recoding.

This package provides an easy to use library to setup, apply and make inference with discrete time and discrete space hidden Markov models.
