Folly
An open-source C++ library developed and used at Facebook
...In particular, it's often a dependency of Facebook's other open source C++ efforts and place where those projects can share code. It complements (as opposed to competing against) offerings such as Boost and of course std. In fact, we embark on defining our own component only when something we need is either not available, or does not meet the needed performance profile. We endeavor to remove things from folly if or when std or Boost obsoletes them. Performance concerns permeate much of Folly, sometimes leading to designs that are more idiosyncratic than they would otherwise be (see e.g. ... -

Scnlib
scanf for modern C++
scnlib is a modern C++ library that serves as a replacement for scanf and std::istream. It offers type-safe and efficient input parsing, aiming to improve upon the limitations of traditional C++ input methods. -

derive(Error)
derive(Error) for struct and enum error types
This is a Rust crate that provides a convenient derive macro (#[derive(Error)]) for implementing std::error::Error on your custom error types (structs or enums). The goal is to enable library authors to build expressive, typed error types, with readable Display implementations (via #[error("...")] annotations) as well as From conversions (#[from]), source tracking (#[source]), and optionally backtraces. It is designed so that switching from handwritten error implementation to using this error is not a breaking change: you retain the same API. ... -

Anyhow
Flexible concrete Error type built on std::error::Error
This is a Rust library (crate) that provides a flexible, concrete error type built atop the standard std::error::Error trait. Its primary goal is to make error handling in applications easy: instead of defining lots of custom error types, you can use anyhow::Error (or the alias anyhow::Result<T>) for fallible functions. The crate supports attaching context to errors, so you can convert a low-level error (like “file not found”) into one with richer diagnostics (“Failed to read instructions from path X”) using .context() or .with_context(). ... -

ArduinoJson
JSON library for Arduino and embedded C++. Simple and efficient
...ArduinoJson can filter large inputs to keep only fields that are relevant to your application, thereby saving a lot of memory. ArduinoJson can parse directly from an input Stream or std::istream. ArduinoJson can produce compact or prettified documents. ArduinoJson works directly with strings stored in program memory. ArduinoJson supports two coding styles, with implicit or explicit casts. ArduinoJson deduplicates strings in the JSON document. When you have several identical keys or values, the JsonDocument only stores one of each. ... -

Usage: - run function blinkLED() every 2000 ms: timer.addEverytime(2000, blinkLED); - run function itWorks() two times with interval 2000 ms, wait 300 ms before first start: timer.addTask(2000, 2, 300, itWorks); Removing a task: removeEverytime(callback_function); removeTask(callback_function); Library can also be used in desktop C++ applications: #include <iostream> #include <string> #include <chrono> #include <thread> #include "RZtimer.h" int main() { RZTimer timer; timer.addEverytime(2000, [] (){ std::cout << "Hello! " << std::chrono::duration_cast<std::chrono::milliseconds >( std::chrono::system_clock::now().time_since_epoch() ).count() << "\n";}); while(1){ timer.run(); std::this_thread::sleep_for(std::chrono::milliseconds(100)); } }

ringBufU
Ring-Buffer library in C, includes support of multithreading
A Ring-Buffer instance could be used with element types - char - long - long long - void* . Focus is on a hardened SW structure with buffer-instance-pointer check (not very fast but more secure). Some features are globally choosable on compile-time (e.g. switch multithread support off completely to have faster access). Note: User Interface is for Test and Tutor Code only. -

Argh!
Argh! A minimalist argument handler
So many different command line processing libraries out there and none of them just work. Some bring their whole extended family of related and unrelated external dependencies (yes, I'm looking at you Boost). Some require quirky syntax and/or very verbose setups that sacrifice simplicity for the generation of a cute usage message and validation. Many come to dominate your main() file and yet others do not build on multiple platforms - for some even their own tests and trivial usage cause... -

rust_cmd_lib
Common rust command-line macros and utilities
...The library also supports features like variable substitution, scoped environment settings, and defining custom commands (functions) that behave like built-ins. It hides much of the boilerplate of std::process::Command when you're doing simple task automations, but still allows full flexibility when needed. Because it avoids launching a shell, it reduces some classes of security and quoting errors, while improving readability of scripting logic inside a Rust binary. -

SoAx
Structure of Arrays of multiple types
Structures of arrays (SoA) are generally faster than arrays of structures (AoS) while AoS are more handy. This project (SoAx) combines the advantages of both. By means of C++(11) meta-template programming SoAx achieves maximal performance (efficient use of vector units and cache of modern CPUs) while providing a very convenient user interface (including object-oriented element handling) and flexibility. It has been designed to handle list-like sets of particles (similar to struct {int id;... -

libvcr
A C++ library for managing configuration files via regular expressions
This library is supposed to be used in your C++ programs for managing simple Unix configuration files like /etc/hosts. The library allows to create default configuration, read the configuration file, validate each found option or value with C++ std::regex, automatically remove incorrect options and even merge several configurations with predefined priorities for each option. So it may be useful in programs which use several configuration files. For an extra example of the library usage see https://sourceforge.net/projects/qsquidclassroom . -

Extensible Exception Library
Simple framework for C++11 exception handling.
EEL stands for 'Extensible Exception Library': it is a simple framework for C++11 exception handling. The concepts behind are the following: - compatibility with the existing std::exception(s); - extensible generic payload for transporting any kind of informations - simple mechanism for extending the payload during the exception handler backtrace - coherent semantic for the final user - low-level diagnostic informations provided 'on demand' -

Simple C++ string and vector classes
Two simple C++ classes, replacements for std::string and std::vector
The classes are useful as training examples for a C+++ tutorial, for novices in C++, or if you have to avoid the standard C++ library with its classes std::string and std::vector class for any reason. It contains basic functionality compatible with the std:: versions, more functions can easily be added. Class my_string is based on original work by Christian Stigen Larsen, 2007. It may happen in real projects that the std library must be avoided: I needed it because of link problems in an application using mixed libraries, especially one compiled with an old Intel compiler icc 7 (for Linux), and other libs compiled with newer compilers. ... -

CLAW is a C++ Library providing various tools in different domains, like a Tweener framework, Bézier curves manipulation, a map with multiple value types, a binary search tree container implemented as an AVL and an implementation of the sockets as std::stream. The library also includes a set of classes to easily load and write png, jpeg, gif files and other image formats. Finally, a part of the library is devoted to artificial intelligence in games and includes a generic alpha-beta algorithm. Each module is provided with an example program.

fncw
generic c++11 function wrapper
fncw is a generic function wrapper for C++11. It support all types of member, lambda and C like functions. unlike std::function, fncw::function is not a template. This mean that you could wrap any function with any signature inside only one type/object: fncw::function. despite this genericity, fncw::function allow the user to reorder the parameter order (a bit like std::bind), check the function signature (there is also a partial check that aim to check only a few parameters). ... -
