[hab] Creation of `hab` binary. #342

fnichol · 2016-04-01T17:04:05Z

This change introduces a new binary into the Habitat ecosystem: the
hab command, which is intended to be a user-facing command set,
seperate from the Habitat Supervisor (called via the hab-sup binary).

The current implementation is a first step: part prototype and part
implementation. It shows a possible command set layout (i.e. a hab <NOUN> <VERB> structure) and short command aliases. Here is the current output from
the help usage:

hab 0.4.0

Authors: The Habitat Maintainers <[email protected]>

"A Habitat is the natural environment for your services" - Alan Turing

USAGE:
    hab [FLAGS] [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    archive    Runs Habitat package archive commands
    help       Prints this message or the help message of the given subcommand(s)
    pkg        Runs Habitat package commands
    rumor      Runs Habitat rumor commands
    sup        Runs Habitat supervisor commands

ALIASES:
    inject      Alias for: 'rumor inject'
    install     Alias for: 'pkg install'
    start       Alias for: 'sup start'

Additionally, subcommand and alias delegation has a first-pass implementation.
This is used for the hap sup subcommand, which actually executes the
hap-sup binary via an execv(3) system call. In other words the hap
program becomes the hap-sup program, passing along all behavior including
help dialogs. The hab start alias also delegates directly to the hab-sup start subcommand.

@fnichol what is the common crate for versus the core crate?

fnichol · 2016-04-05T20:09:06Z

@reset I'm hoping this could be a temporary crate that is hosting some common code to both the hab CLI and the hap-sup Supervisor. If the code went into core then all other projects (hab-depot, builder-*, etc.) would gain that extra code and any deps. required. I needed to make depot-client API calls which left me at a circular dependency loop (depot-client requires core, which depot-core) and so put the code in "another spot". Not a fan of the name ATM, but it got the feature work completed.

LGTM

@fnichol looks good to me as long as the common crate is a temporary solution. Let's do it:
