As always when this topic comes up, I have to plug Ceu[0] (formerly Céu) and the programming paradigm it represents. It doesn't use coroutines but synchronous concurrency. On top of that it's a reactive language: // an external input event channel input int KEY; // par/or concurrently executes two // or more blocks (called "trails") // if one of them terminates, the // other trails are aborted. // Compare: par/and, which waits // for all trails to terminate // before resuming code par/or do // an infinite loop that awaits // a timer event. Therefore this // trail never terminates by itself every 1s do // Ceu uses C as a host language // and compiles to (essentially) // a giant finite state machine // C functions can be accessed /
Read the rest
/ using an underscore prefix _printf("Hello World!\n"); end with // this trail awaits a keypress, // then terminates, ending the entire // par/or block. await KEY; // awaits KEY input event end _printf("Bye!\n"); The above code prints "Hello World!" ever second, until a key is pressed, after which it prints "Bye!" before terminating the program. The reactivity and intuitive single-threaded concurrency makes it a really nice language for low-powered devices. Or robotics, which is a lot about reacting to sensor input. It has a dedicated Arduino repo too[1]. In practice it's more of a research language by Francisco Sant’Anna, a professor at UERJ, Brazil, than a language with a big community around it. He's currently working on a new version caleld Dynamic Ceu, or dceu[2] In the same paradigm there is the Blech[3] language, I believe originating from Bosch. Sadly, that project also has lost some steam. [0] https://github.com/ceu-lang/ceu-arduino [1] http://ceu-lang.org/ [2] https://github.com/fsantanna/dceu [3] https://github.com/blech-lang/blech
In Coroutines make robot code easy
