Finalizing the Integration of Cobra into Multi-git

Explore how to complete the integration of Cobra into the multi-git project by refactoring main.go to execute the root command, reorganizing file structure, and updating test helpers. Understand adapting command-line parsing and flags in Go applications for streamlined CLI program design and easier maintenance.

We'll cover the following...

Refactor the main.go file

With the root command fully implemented, we need to refactor the main.go file, so it executes the Cobra root command instead of all the work it’s currently doing.

The location of main.go should also change. At the moment, it is in cmd/mg/main.go, but Cobra applications have a main.go file at the top-level directory of the project.

The main.go is very simple, and it just executes the root command:

package main

import "github.com/the-gigi/multi-git/cmd"

func main() {
	cmd.Execute()
}

The only unique thing about main.go is that it uses the Go module name to import the cmd package where the root command exposes the Execute() function.

Let’s give it a ...
