go run

go run will run a program without creating an executable file. Mostly useful for development. run will only execute packages whose package name is main.

To demonstrate, we will use a simple Hello World example main.go:

package main

import fmt

func main() {
    fmt.Println("Hello, World!")
}

Execute without compiling to a file: go run main.go

Run multiple files in package

If program is split into multiple files, you must provide all files:

$ go run main.go assets.go
