Results for: "OptionParser"

Iterates the given block for each element with an index, which starts from offset. If no block is given, returns a new Enumerator that includes the index, starting from offset

offset

the starting index to use

Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.

["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force
#=> ["f", "o", "o", "b", "a", "r"]

A value x returned by block is decomposed if either of the following conditions is true:

• x responds to both each and force, which means that x is a lazy enumerator.

• x is an array or responds to to_ary.

Otherwise, x is contained as-is in the return value.

[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]

Like Enumerable#select, but chains operation to be lazy-evaluated.

Like Enumerable#take_while, but chains operation to be lazy-evaluated.

Returns the Object#object_id of the internal object.

Extracts addr from IPV6_PKTINFO ancillary data.

IPV6_PKTINFO is defined by RFC 3542.

addr = Addrinfo.ip("::1")
ifindex = 0
ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex)
p ancdata.ipv6_pktinfo_addr #=> #<Addrinfo: ::1>

Extracts ifindex from IPV6_PKTINFO ancillary data.

IPV6_PKTINFO is defined by RFC 3542.

addr = Addrinfo.ip("::1")
ifindex = 0
ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex)
p ancdata.ipv6_pktinfo_ifindex #=> 0

Creates a new Socket::Option object for IP_MULTICAST_TTL.

The size is dependent on the platform.

p Socket::Option.ipv4_multicast_ttl(10)
#=> #<Socket::Option: INET IP MULTICAST_TTL 10>

Returns the ipv4_multicast_ttl data in sockopt as an integer.

sockopt = Socket::Option.ipv4_multicast_ttl(10)
p sockopt.ipv4_multicast_ttl => 10

Load an iseq object from binary format String object created by RubyVM::InstructionSequence.to_binary.

This loader does not have a verifier, so that loading broken/modified binary causes critical problem.

You should not load binary data provided by others. You should use binary data translated by yourself.

Creates a regular expression to match IPv4 addresses

Set the default value for the :argc_limit option.

See new(). The initial default value is 256.

Set the default value for the :id_conv option.

See new(). The initial default value is a DRbIdConv instance.

Check that a method is callable via dRuby.

obj is the object we want to invoke the method on. msg_id is the method name, as a Symbol.

If the method is an insecure method (see insecure_method?) a SecurityError is thrown. If the method is private or undefined, a NameError is thrown.

Example:

Foo::Bar += 1
   ^^^^^^^^

WARNING This method opens a serious security hole. Never use this method in production code.

Sets an output stream for debugging.
