Starting with Go language by Google

http://golang.org/

1. Download and Install the Go - no configuration needed
2. Add variable:
~@ ~ $ edit ~/.profile


# Go
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin

3. Close and open Terminal

@ ~ $ which go
/usr/local/go/bin/go

4. create a sample program

@ workspaces $ mkdir go_programs
@ workspaces $ touch hello.go
@ workspaces $ edit hello.go 
@ workspaces $

Editor:

package main

import "fmt"

func main() {
    fmt.Printf("hello, world\n")
}


Edit PATH again:

# Go
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
export GOPATH=~/Documents/workspaces/go_programs
export PATH=$PATH:$GOPATH


5. Run your first program
@ workspaces $  go run hello.go
hello, world

6. Take a tour
