Learning Functional Programming in Go

Working code

Let's look at some example code to illustrate this concept. First, let's look at the working code. The packageb package has one, simple public function and no imports:

dependency-rule-good/src/packagea/featurea.go

package packagebfunc Btask() {   println("B")}

The packagea package has one, simple public function and imports packageb:

// dependency-rule-good/src/packageb/featureb.gopackage packageaimport b "packageb"func Atask() {   println("A")   b.Btask()}

Here's our main function where we run Atask from packagea:

// dependency-rule-good/main.gopackage mainimport a "packagea"func main() {   a.Atask()}

Output:

AB
