如何构造go命令内部

Question

If your writing a go command (not a package) that is large how do you layout its internals? I would love to have some utility packages etc but not have those exposed for anything except the command's code. If it's all in the same repo I don't see whats stopping someone from importing those internal use packages.

Answer 1

You might make your utility packages internal to your package — like this. This won't prevent anyone from using them but a) why would you care anyway? b) the package's structure would give a clear hint on that these "subpackages" are internal to the project.
