Instance Method Details

#parse(args = ARGV) ⇒ Hash

Parse an array of arguments into a Hash of options

Examples:

args = ['--option', 'value', '--option2', 'value2', '--switch']
parser = CommandLineParser.new
parser.parse(args) == {:option => 'value, :options2 => value, :switch => true}

Parameters:

• args (Array) (defaults to: ARGV) —

  The array of arguments to consume

Returns:

• (Hash) —

  Return the Hash of options

# File 'lib/beaker/options/command_line_parser.rb', line 315

def parse( args = ARGV )
  @optparse.parse(args)
  @cmd_options
end

#usage ⇒ String

Generate a string representing the supported arguments

Examples:

parser = CommandLineParser.new
parser.usage = "Options:  ..."

Returns:

• (String) —

  Return a string representing the available arguments

# File 'lib/beaker/options/command_line_parser.rb', line 327
