Learning Functional Programming in Go

Code with cyclic dependency error

This time, we will import packagea into featureb.go:

// circulardep/src/packageb/featureb.gopackage packagebimport a "packagea"func Btask() {   println("B")   a.Atask()}

The featurea.go file remains unchanged:

package packageaimport b "packageb"func Atask() {   println("A")   b.Btask()}

The main.go file also remains unchanged:

package mainimport a "packagea"func main() {   a.Atask()}

The following is the output:

import cycle not allowedpackage mainimports packageaimports packagebimports packagea

We violated the dependency rule when we imported packagea into featureb.go.
