OptBind

Binds command-line options to variables.

Extends command-line option analysis by wrapping an instance of standard OptionParser. Enables binding of options and arguments to instance or local variables. Provides Hash and String only interfaces to define command line options, unlike a mixed interface by standard library. Supports access to default values and partial argument analysis. Builds Git-like options and help by default.

Installation

bundle install optbind

Usage

Bind local variables to ARGV and parse command line arguments:

require 'optbind'

ARGV                                         #=> ['--no-verbose', '-o', 'file.out', 'file.in'] 

i, o, v = STDIN, STDOUT, true

ARGV.bind_and_parse! to: :locals do
  use '[<options>] [<file>]'
  use '--help'
  opt 'o -o --output=<file>'
  opt 'v -v --[no-]verbose'
  arg 'i [<file>]'
end

[i, o, v]                                    #=> ['file.in', 'file.out', false]

See specs for more examples and details on usage.
