go mod init example.com/greetings

The go tool provides several commands that are related to modules.

• go mod init - initializes new module in current directory
• go mod tidy - adds missing and removes unused modules
• go mod download - downloads modules to local cache
• go mod vendor - makes vendored copy of dependencies
• go mod graph - prints module requirement graph
• go mod verify - verifies dependencies have expected content
• go mod why - explains why packages or modules are needed

There are additional commands related to Go modules.

The go list -m lists available modules. The go get installs dependencies and updates the go.mod file. The go build and go test commands add new dependencies to go.mod as needed.

• https://thewebivore.com/using-replace-in-go-mod-to-point-to-your-local-module/ The problem is because you have not publish your module to a central location like github. You have to run this command to tell go that the module is a local module

go mod edit --replace external_folder_module_name= ../pathItsLocated

$ go mod edit -replace github.com/pselle/bar=/Users/pselle/Projects/bar
