Method: Argvector#assoc_options

Defined in:
lib/supplemental/facets/argvector.rb

#assoc_options(args) ⇒ Object

Parse flags takes the command line and transforms it such that flags (eg. -x and –x) are elemental associative arrays.

line = "--foo hello --try=this"
argv = Argvector.new(line)

args = line.split(/\s/)
argv.assoc_options(args)  #=> [ ["foo",true], "hello", ["try","this"] ]
