module Gem::OptionParser::Arguable
Extends command line arguments array (ARGV) to parse itself.
Public Class Methods
Initializes instance variable.
# File rubygems/vendor/optparse/lib/optparse.rb, line 2308 def self.extend_object(obj) super obj.instance_eval {@optparse = nil} end
# File rubygems/vendor/optparse/lib/optparse.rb, line 2312 def initialize(*args) super @optparse = nil end
Public Instance Methods
Substitution of getopts is possible as follows. Also see Gem::OptionParser#getopts
.
def getopts(*args) ($OPT = ARGV.getopts(*args)).each do |opt, val| eval "$OPT_#{opt.gsub(/[^A-Za-z0-9_]/, '_')} = val" end rescue Gem::OptionParser::ParseError end
# File rubygems/vendor/optparse/lib/optparse.rb, line 2301 def getopts(*args, symbolize_names: false) options.getopts(self, *args, symbolize_names: symbolize_names) end
Actual Gem::OptionParser
object, automatically created if nonexistent.
If called with a block, yields the Gem::OptionParser
object and returns the result of the block. If an Gem::OptionParser::ParseError
exception occurs in the block, it is rescued, a error message printed to STDERR and nil
returned.
# File rubygems/vendor/optparse/lib/optparse.rb, line 2260 def options @optparse ||= Gem::OptionParser.new @optparse.default_argv = self block_given? or return @optparse begin yield @optparse rescue ParseError @optparse.warn $! nil end end
Sets Gem::OptionParser
object, when opt
is false
or nil
, methods Gem::OptionParser::Arguable#options
and Gem::OptionParser::Arguable#options=
are undefined. Thus, there is no ways to access the Gem::OptionParser
object via the receiver object.

Parses self
destructively in order and returns self
containing the rest arguments left unparsed.
# File rubygems/vendor/optparse/lib/optparse.rb, line 2276 def order!(&blk) options.order!(self, &blk) end
Parses self
destructively and returns self
containing the rest arguments left unparsed.
# File rubygems/vendor/optparse/lib/optparse.rb, line 2288 def parse!() options.parse!(self) end
Parses self
destructively in permutation mode and returns self
containing the rest arguments left unparsed.
# File rubygems/vendor/optparse/lib/optparse.rb, line 2282 def permute!() options.permute!(self) end
