Hello World
Just started learning golang and tried to figure out how to structure a larger program. Not sure if packages are the split I want or if there is something else more suitable for having multiple source files in a single directory, but here's what I tried.
package main
import "fmt"
func main() {
fmt.Printf("hello, world\n")
}
Testing running it:
~/b2/go/src/github.com/bemmu/hello bemmu$ go run hello.go
hello, world
Two file version
I wanted to try splitting it into two files.
main.go
package main
import "fmt"
import "say"
func main() {
say.Hello()
}
say.go
package say
import "fmt"
func Hello() {
fmt.Printf("hello, Go\n")
}
Testing running it:
~/b2/go/src/github.com/bemmu/hello_split bemmu$ go run main.go
main.go:4:8: cannot find package "say" in any of:
/usr/local/go/src/say (from $GOROOT)
/Users/bemmu/b2/go/src/say (from $GOPATH)
In the docs there is an example of creating a library and importing it, but in the example case it is put into a separate directory.
