Version

Returns version string from program_name, version and release.

Parses command line arguments argv in order. When a block is given, each non-option argument is yielded. When optional into keyword argument is provided, the parsed option values are stored there via []= method (so it can be Hash, or OpenStruct, or other similar object).

Returns the rest of argv left unparsed.

Same as order, but removes switches destructively. Non-option arguments remain in argv.

Parses command line arguments argv in permutation mode and returns list of non-option arguments. When optional into keyword argument is provided, the parsed option values are stored there via []= method (so it can be Hash, or OpenStruct, or other similar object).

Same as permute, but removes switches destructively. Non-option arguments remain in argv.

Wrapper method for getopts.rb.

params = ARGV.getopts("ab:", "foo", "bar:", "zot:Z;zot option")
# params["a"] = true   # -a
# params["b"] = "1"    # -b1
# params["foo"] = "1"  # --foo
# params["bar"] = "x"  # --bar x
# params["zot"] = "z"  # --zot Z

See getopts.

Loads options from file names as filename. Does nothing when the file is not present. Returns whether successfully loaded.

filename defaults to basename of the program without suffix in a directory ~/.options, then the basename with ‘.options’ suffix under XDG and Haiku standard places.

Returns the regexp.

m = /a.*b/.match("abc")
m.regexp #=> /a.*b/

Looks up all IP address for name.

Looks up the hostname of address.

Looks up all hostnames for address.

Closes the file. If unlink_now is true, then the file will be unlinked (deleted) after closing. Of course, you can choose to later call unlink if you do not unlink it now.

If you don’t explicitly unlink the temporary file, the removal will be delayed until the object is finalized.

Closes and unlinks (deletes) the file. Has the same effect as called close(true).

Returns the parameter information of this proc.

prc = lambda{|x, y=42, *other|}
prc.parameters  #=> [[:req, :x], [:opt, :y], [:rest, :other]]

Returns a clone of this method.

class A
  def foo
    return "bar"
  end
end

m = A.new.method(:foo)
m.call # => "bar"
n = m.clone.call # => "bar"

Returns the bound receiver of the method object.

(1..3).method(:map).receiver # => 1..3

Returns the class or module that defines the method. See also Method#receiver.

(1..3).method(:map).owner #=> Enumerable
