A Makefile for your Go project (2019)
My most loathed feature of Go was the mandatory use of GOPATH:
I do not want to put my own code next to its dependencies. I was not

The go command resolves imports by using versions listed in
go.mod. When it runs into an import of a package not present in
go.mod, it automatically looks up the module containing that package
using the latest version and adds it.
$ go test ./... go: finding github.com/spf13/cobra v0.0.5 go: downloading github.com/spf13/cobra v0.0.5 ? hellogopher [no test files] ? hellogopher/cmd [no test files] ok hellogopher/hello 0.001s $ cat go.mod module hellogopher require github.com/spf13/cobra v0.0.5
If you want a specific version, you can Continue reading
