nimforum mirror - Nim concurrency

Hi, I've recently become aware of nim.

It looks interesting although I still don't quite get the concurrency constructs built into the language.

I've seen here and there that the concurrency construct is compared to golang, but I don't see goroutines or channels.

The furthest I've seen is spawn to execute code in a different thread.

I'm sure I'm missing something, I'd appreciate some enlightenment on this matter

Thanks in advance

If you are looking for coroutines then you can exploit iterators (with {.closure.} pragma). But you would need to write a bit of management code.

There are various options for concurrency in Nim. For starters see http://nim-lang.org/manual.html#threads for threads and channels.

You can spawn multiple threads, each has its own gced heap. I think isolated heaps is much better than shared everything by default.

Within a thread, you can use coroutines (async and await) for concurrency of IO intensive tasks. See http://nim-lang.org/asyncdispatch.html

New location of the asyncdispatch documentation: http://nim-lang.org/docs/asyncdispatch.html

Probably, you are looking for the coro module, which implements coroutines in Nim. Channels are also present in the language.
