Refactoring the Command-Line interface
We'll refactor the command-line interface of multi-git into its proper place in our directory structure in this lesson.
We'll cover the following...
In this lesson, we will not make changes to the functionality. We’ll just move files around. This measured approach of separating refactoring from functional changes helps us eliminate many problems and if something does go wrong, it is easier to identify the root cause and fix it.
Planning the refactoring
In the previous lesson, we refactored the core logic into a set of packages under the pkg top-level directory. Now, we will do something similar for the command-line interface. We will move into a new subdirectory called mg, which is short for multi-git under the cmd top-level directory. This follows established conventions in the Go community. It will allow adding additional commands later if necessary.
The plan is as follows:
- Create the multi-git command
- Move the code from the main() function into the new command
- Verify that everything still works
Let’s get to it!
Creating the command
Creating the command is as simple as creating the top-level directory, cmd, and a sub-directory called, mg: ...
