optparse-subcommand
This gem extends Ruby's standard library OptionParser class to allow popular
subcommand-style tools (e.g. git).
Usage
A new method subcommand is added to the OptionParser instance allowing you
to define an action to occur when that subcommand is detected as an argument.
The subcommand method takes a block which yields a new OptionParser instance.
Simply define your option parsing recursively for all subcommands.
Example:
require 'optparse/subcommand' # Also requires 'optparse'
require 'ostruct'
options = OpenStruct.new
options.verbose = false
options.action = nil
options.action_options = OpenStruct.new
parser = OptionParser.new do |opts|
opts.on '-v', '--[no-]verbose' do |verbose|
options.verbose = verbose
end
opts.subcommand 'foo' do |foo|
options.action = :foo
foo.on '-x' do
options.action_options.x = true
end
end
end
parser.parse(%w[-v foo -x]) # or ARGV, whatever...
options # => #<OpenStruct verbose=true, action=:foo, action_options=#<OpenStruct x=true>>License
