What Hacker News says
17 sources> maybe there's a Guile/Scheme library somewhere out there that Emacs could desperately use.
It isn't the reason for Guile Emacs, but there is in fact a library Emacs could quite desperately use: fibers (<https://github.com/wingo/fibers>). The Emacs concurrency story is about as bad as you could expect from a 40+ year old application.
In Using Guile for EmacsFibers is probably used more in the Guile community these days
https://github.com/wingo/fibers
In 8syncMore like goroutines. They remind me of Guile's fibers: https://github.com/wingo/fibers
In Virtual Threads Arrive in JDK 21, Ushering a New Era of ConcurrencyDo you mean like fibers ( https://github.com/wingo/fibers ), or something beyond that?
In A Scheme PrimerAlso possibly of interest here: https://github.com/wingo/fibers/wiki/Manual
In libmill - Go-style concurrency in CA brief history of language facilities for concurrency
2 points · Open discussionGo's concurrency primitives are a less expressive version of concurrentML, which imo has been the nicest way of writing concurrent (but for a long time not parallel) applications the last 30 years.
Guile scheme has a parallel version of it that is implemented as a library: https://github.com/wingo/fibers/wiki/Manual
Comparing concurrent systems is hard. I would suggest implementing selecting with negative acknowledgement (nack). If I can do that nicely I know I will probably like the system.
In A History of Clojure [pdf]What y'all need is concurrent ML. I don't know why, but it still seems rather unknown. For me it hits the sweet spot of power and flexibility (generalising the actor model and still not having to do the nitty gritty details of reagents). Guile scheme has what is probably the nicest implementation (utilizing multiple cores) and the best introduction:
https://github.com/wingo/fibers/wiki/Manual
In Asynchronous programming and cooperative multitaskingAndy Wingo uses delimited continuations to implement guile fibers https://github.com/wingo/fibers/wiki/Manual
It is a low level construct that can be used to build higher abstractions and things like coroutines. In a language like scheme they can also be a (costly) way to do early escapes.
If you are into nondeterminism they are also quite usable.
call/cc is being retired in favour of delimited continuations, which is a good thing.
Most often you don't need them. Implementing things like generators using continuations is possible, but it is also a lot slower than built in support for generators.

1 points · Open discussionAndy Wingo's fibers for guile scheme is similar:
https://github.com/wingo/fibers/wiki/Manual
Really neat, and the implementation is really a testament to the power of delimited continuations.
In Coroutines are now in Clang trunk, libc++This showed up in the guile-user mailing list this week and looks pretty cool. The manual for the project is here: https://github.com/wingo/fibers/wiki/Manual
