Initially I'm following the tutorials published on GO's website.
I will place here any information I think its useful for me (or you) for later reference.
$ go mod init [your-module-sourcecode-url]
Enables dependency tracking of your module by creating a go.mod
file in the project's root directory.
This file contains your code dependencies as well as a path-URL to find your code [possibly online].
$ go mod tidy
From the official documentation:
Tidy makes sure go.mod
matches the source code in the module.
It adds any missing modules necessary to build the current module's
packages and dependencies, and it removes unused modules that
don't provide any relevant packages. It also adds any missing entries
to go.sum and removes any unnecessary ones
go mod edit -replace example/greetings=../greetings
Tells go.mod where to find a local package. In this case it tells to find example/greetings
in ../greetings
. This is only recommended for code that is used locally.
