In modern C++ development, coroutines have brought revolutionary changes to asynchronous programming. However, when using boost::asio or standalone asio, we often encounter scenarios where we need to convert traditional std::future to asio::awaitable. This article will detail an efficient, thread-safe conversion … Read more
For the past few months I’ve been mulling over some things that Russell Johnston made me realize about the relationship between effect systems and coroutines. You can read more of his thoughts on this subject here, but he made me … Read more
Coroutines in C by Simon Tatham [Coroutines trilogy: C preprocessor | C++20 native | general philosophy ] Introduction Structuring a large program is always a difficult job. One of the particular problems that often comes up is this: if you … Read more
This post is about why we need a coroutine package for Go, and what it would look like. But first, what are coroutines? Every programmer today is familiar with function calls (subroutines): F calls G, which stops F and runs … Read more
June 19, 2023 I love the FIRST Robotics Competition. It’s absolutely the best way for high school kids to learn engineering and programming. When I was on a team in high school, I was the Software Kid and did all … Read more
This blog post is one of a two part series. Introduction C++ is late to the coroutine party, compared to other programming languages, but they are part of C++20. Prior to coroutines, a C++ programmer had two choices, roughly speaking: … Read more
C++20 added minimal support for coroutines. I think they’re done in a way that really doesn’t fit into C++, mostly because they don’t follow the zero-overhead principle. Calling a coroutine can be very expensive (requiring calls to new() and delete()) … Read more
