Method: Canis::App#get_command_from_user

Defined in:

lib/canis/core/util/app.rb

#get_command_from_user(choices = ["quit","help", "suspend", "shell_output"]) ⇒ Object

prompts user for a command. we need to get this back to the calling app or have some block stuff TODO Actually, this is naive, you would want to pass some values in like current data value or lines ?? Also may want command completion, or help so all commands can be displayed NOTE: This is gonna change very soon - 2012-01-8
