--version for subcommands #6

Closed alessiostalla closed 1 year ago

alessiostalla commented 1 year ago

Subcommands list a --version option but that doesn't seem to do anything:

$ ./portofino new --help
NAME:
  portofino new - Create a new Portofino project

USAGE:
  portofino [global-options] new [options] [arguments ...]

OPTIONS:
     [...]
      --version                    display version and exit
     [...]

$ ./portofino new --version
[no output]

This is because you haven't specified a value for the :version slot of the sub-command.

The idea behind this is that sub-commands may have a different version than the parent command. As an example, I may be building a CLI tool where I develop some part of the code, and then I can pull in as a dependency some other system/package, which provides another set of commands in order to have one single CLI which combines multiple commands from different packages/systems.

I've also pushed a commit, which now tries to find a parent command, for which there is a :version associated with.

Try it out and let me know how it goes.

Yep, that was it, thanks!
