Go Example Code

Go is an awesome language.

Syntax

package main

import "fmt"

func main() {

    fmt.Println("Hello!")

    var a = 1   // declare type and initialize
    b := 2      // automatic type and initalize

    msg := bye("Stan")
    fmt.Println(msg, a, b) // multiple echos
}

func bye(name string) string { // types specified
    return "goodbye " + name
}

Brackets

package main

import "fmt"

func main() {

    var a = 1

    {
        var b = 2
    }

    fmt.Println(a, b)
}

Struct

package main

import "fmt"

type Man struct {
    Age int
    Name string
}

func main() {

    joe := Man { Age: 63, Name: "Joe" } // cool
    stan := Man {}; // defaults stuff to "zero"
    gavin := Man { Age: 12 }
    gavin.Name = "Gavin"

    fmt.Println(joe, stan, gavin)
}

Conditionals

package main

import "fmt"

func main() {
    a := false
    b := 2

    if !a && b > 1 {
        fmt.Println("if")
    } else if b > 3 || (b < 10 && b > 4) {
        fmt.Println("else if")
    } else {
        fmt.Println("else")
    }

    c := "foo"
    switch (c) {
        case "foo":
            fmt.Println("reasonable")
            break
    }
    switch {
        case c == "foo":
            fmt.Println("case a")
            break;
        case b < 3:
            fmt.Println("case b")
            break;
    }

    for i := 0; i < 2; i++ {
        fmt.Println("two loops")
    }
    for true {
        //fmt.Println("forever")
    }
}
