Modulinos: Difference between revisions

=={{header|Go}}==

Go doesn't support scripted main directly.

Although the [https://github.com/mcandre/modulinos examples] linked to above include an example for Go, this is only a work around, not an emulation. To emulate a modulino, we need to proceed as in the [[https://rosettacode.org/wiki/Executable_library#Go Executable library]] task and split the 'main' package into two.

First create these two files in the 'modulino' directory:

<lang go>// modulino.go

package main

import "fmt"

func MeaningOfLife() int {

return 42

}

func libMain() {

fmt.Println("The meaning of life is", MeaningOfLife())

}</lang>

<lang go>// modulino_main.go

package main

func main() {

libMain()

}</lang>

To emulate a modulino:

{{out}}

<pre>

$ go run modulino

The meaning of life is 42

</pre>

Now create this file in the 'mol' directory:

<lang go>// mol.go

package main

import "fmt"

func main() {

fmt.Println("The meaning of life is still", MeaningOfLife())

}</lang>

and copy modulino.go to the 'mol' directory. The library can then be used in the 'normal' way:

{{out}}

<pre>

$ go run mol

The meaning of life is still 42

</pre>
