Do people have some motivating examples for co-routines?

• CoroGB

  3 48 0.0 C++

  CoroGB is an experimental gameboy emulator written in C++ w/ coroutines

A Gameboy emulator that uses coroutines and custom awaitable types to handle component scheduling: https://github.com/TheThief/CoroGB

• Web

  1 0 0.0 C++

  Old experimental web server using fibers, io completion ports, and some early C++11 features. (by TheThief)

A webserver I created ages ago that used OS fibers for parallel request processing in a very similar manner to how you could use coroutines: https://github.com/TheThief/Web

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• drdestructo2

  1 29 0.0 C++

  Repository for Return of Dr. Destructo, a remake of "Island of Dr. Destructo"

I haven't got an example in C++, but I got an example in Lua mixed with C++, which I used for my pet project some years ago. Here it is. Let's see what's happening here:

• coproto

  1 6 5.9 C++

  Discontinued A protocol framework based on coroutines

Here's a networking library that compares with and without coroutines. https://github.com/ladnir/coproto

• hardglitch

  4 8 0.0 JavaScript

  JS project led by Klaim in HomeTeamGameDev, May 17 - Oct 11, 2020

  

Not C++ but I'm working on a turn-by-turn game with animations etc. which relies a lot on coroutines (in JavaScript for this one). The code is there if you want to take a look: https://github.com/gamkedo-la/hardglitch (the game is playable there in the deployments, or in it's released version on itch: https://klaim.itch.io)

• libunifex

  22 1,366 7.6 C++

  Unified Executors

  

Yeah here's an example of code that uses coroutines: https://github.com/facebookexperimental/libunifex/blob/8311d141d6654acbff269b90f1836c3186b4a092/examples/linux/io_epoll_test.cpp#L165

• cppcoro

  24 3,235 0.0 C++

  A library of C++ coroutine abstractions for the coroutines TS

I used cppcoro to build this library (still working on it).

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• Flow

  2 9 0.0 C++

  Flow is a software framework focused on ease of use while maximizing performance in closed closed loop systems (e.g. robots). Flow is built on top of C++ 20 coroutines and utilizes modern C++ techniques. (by ManuelMeraz)
