Task Options
Reported by bahuvrihi | May 20th, 2008 @ 12:41 AM
OptionParser
//on tail
properties = {
:arg => # [:mandatory, :optional, :switch, list, [] indicating selection]
:cast => # Class
:block => # perform something novel... by default the block simply sets config with result. }
Converting to properties
no cast:
default indicated by &type.
then no arg, for cast:
Bloolean => switch
Array => list
Error if list and cast to something other than Array?
type: string, boolean, float, integer, array, selection (in?), yaml
Usage
Pickup documentation from RDoc... no help messages specified ( add later ? )
Evaluate options in context with: config, argv, option class
API
opt defines option properties, no actual config. Block, same as above. Non-configs are simply passed into task.config and stored.
Need an class_options class to hold this information. Should be separate from ClassConfiguration as they apply in different contexts.

Tests have shown that options are not a good idea. The main isssue is that there is no way to set a proper context for the option block. This resulted in problems during inheritance as well as simply getting access to the active OptionParser for printing help.
