Simple Terminal for Locomotive!

var lcm = require('jake-lcm')
         , repl = require('repl');


// More about jake-lcm here: https://github.com/drudge/jake-lcm
lcm.exec(
    {
      initializers: ['00_generic', '02_mongoose', '03_models']
    },
    function () {

      repl.start({
        prompt: "Locomotive: > ",
        input: process.stdin,
        output: process.stdout
      });


      }
    );

Here's a quick example of using it:

In my 00_generic initializer I set up a global container, myapp:

    var myapp = global.myapp = {};
    myapp.set = this.set.bind(this);
    myapp.root = process.cwd();
    ....

In the example above, I just loaded the 03_models initialzier, so now I can create and test a user:

  Locomotive: > User = myapp.User

That dumps the whole mongoose User object to the terminal, so you can do this instead:

  Locomotive: > User = myapp.User; "done"

Next, create a user in the terminal:

  Locomotive: > test_user = new User({ email: 'test@example.com', display_name: 'Joe Tester'});
  { email: 'test@example.com',
    display_name: 'Joe Tester',
    _id: 51a7d082a99457d42f000002,
    balance: 0,
    status: 'offline',
    password_salt: '5e69ffpbac1y8pvi',
    created_at: Thu May 30 2013 15:19:46 GMT-0700 (PDT),
    roles: [ 'user' ] }
  Locomotive: > 

Works pretty well for me.
