Cool, thanks for the work! I can't test this right now as I'm away but if someone could test this out it'd be fantastic and we can get it merged. |

@thethomaseffect thanks! Let me know if there is anything I can do to help, or if you need me to fix/change the approach I have taken. |

What's the purpose for these try/catch blocks? These are tests, we'd want all exceptions to bubble up.

I was cribbing from https://github.com/visionmedia/commander.js/blob/master/test/test.options.commands.js#L103. Basically, we hijack process.exit(x) and have it throw an error (which help calls process.exit(0)) https://github.com/visionmedia/commander.js/pull/245/files#diff-48e1e0644a9c6aeb3fee25b9561b1692R60 We are OK with having the program exit (that is what help is supposed to do) but we want to assert that it was actually called (we add a on('help') above that sets the variable if help is called.

@SomeKittens have you run into any issues while testing/reviewing this code? No pressure, just want to see if there is anything I can do to help! |
Nested command support was almost completely available, however, a few things seemed to be missing to me. * `this` context on `action` event listeners was not bound properly. * We output `help` too early, the deepest referenced command should handle help.

My first day with node-commander and I've already hit issues solved by this PR. Would be so good if someone could look at this but there seems to be many neglected PRs :( |

@ohjames We can't merge this - there's a bunch of conflicts... |

Don't have the time to help out with this, found another library that supports it. |

@apla thanks for the update, I'm your first star! Hoping you've finally made the holy grail of node.js cmd line argument parsers. |

Did this feature (nested commands) ever happen? |
|
@boutell nope I've been using yargs for the past few years instead. It's pretty good. |

thiscontext onactionevent listeners was not bound properly.helptoo early, the deepest referenced command should handle help.actionhandling logic to delegate to subcommands if they existed.This should address #226, and #1. Pretty much all of the support was already there, and it seemed useful to just connect the wires. I know that #63 referenced using the git subcommand model, which I love and use frequently, but there are several use cases (creating a command framework that loads external "plugin" module commands into the parent executable) that would be more easily expressed with this simple fix to connect the wires for sub-commands.
