The Evie Language

Evie is a dynamically typed scripting language written in Golang.

Here is some example code

package main

fn main() {
    echo fib(35)
}

fn fib(n) {
    if (n < 2) return n
    
    return fib(n-1) + fib(n-2)
}

Concurrency example

package main

fn print(message, duration) {
    await time.timer(duration) // timer will return a 'task' that we await on
    echo message
}

fn main() {
    // keyword 'go' starts a new coroutine
    go print("one", 100)
    go print("two", 200)
    go print("three", 300)
    go print("four", 400)
    go print("five", 500)
    go print("six", 600)
    go print("seven", 700)
    go print("eight", 800)
    go print("nine", 900)
    go print("ten", 1000)
}

To test this exact program cd to ./use and run go run . -t go.es

• flag -t prints the time it took to execute
• flag -p prints the byte code of the program, before running it
• flag -o=true/false enables or disables specialised instruction optimisations. It's true by default

Features

• Highly performant
• Builtin concurrency
• Very similar to Go and other existing languages
• Embeddable in your Go applications
• Can also be run in standalone mode for scripts
• No cgo, written in pure Go
