argvard's Issues

Python 3.4 on travis

Travis doesn't have Python 3.4 installed. Can we install it?

Ability to show usage help on main

Currently argvard forces the user to define a main function, and do something useful in it. However, i have the situation where i can't do anything meaningful in main(), so i want to display the help there and exit with code 1. Currently i do this in main:

app.options['--help'].function(context)

but it would be nice to do this in a documented way. I see two options:

1.) define a default main function which does exactly that (in other words, don't force the user to define a main function)
2.) define an API for showing the help and exiting with code 1.
3.) Both.

Make "context" a thread local?

1. insert any general pros and cons about threadlocals
2. Currently there is no way to get the context from a type callable which was passed to an annotation. But having an explicit context arg there destroys the "purity" of the API IMO.

Allow invoking options/commands relative to the currently executed option/command

I'd like to make it possible to invoke options and commands by providing an API like delegate(context, argv). In this case argv could be something like ['--help'] to call the help function but one could also include arguments or make more complicated calls like [command --option argument].

Fundamentally this would call __call_ with the current context skipping any setup code.

Merge with click?

@mitsuhiko just released click, whose API seems similar to argvard.
