The Rye programming language is a dynamic scripting language based on REBOL’s ideas, taking inspiration from the Factor language and Unix shell. Rye is written in Go and inherits Go’s concurrency capabilities, including goroutines and channels. Recently, Rye gained support for Go’s select and waitgroups. Building blocks Goroutines Goroutines are lightweight threads of execution that are managed by the Go/Rye runtime. They operate independently, allowing multiple tasks to run concurrently without blocking each other. Creating a Goroutine in Rye is straightforward. The go keyword is used to launch a new Goroutine, followed by the Rye function to be executed concurrently. For instance, the following code snippet creates and starts a Goroutine that prints a message after a delay: ; # Hello Goroutine print "Starting Goroutine" go does { ; does creates a function without arguments sleep 1000 print "Hello from Goroutine!" } print "Sleepi
