Creates a new Socket::Option object for IP_MULTICAST_LOOP.
The size is dependent on the platform.
sockopt = Socket::Option.int(:INET, :IPPROTO_IP, :IP_MULTICAST_LOOP, 1) p sockopt.int => 1 p Socket::Option.ipv4_multicast_loop(10) #=> #<Socket::Option: INET IP MULTICAST_LOOP 10>
Returns the ipv4_multicast_loop data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_loop(10) p sockopt.ipv4_multicast_loop => 10
Set the default value for the :argc_limit option.
See new(). The initial default value is 256.
Constructs proper parameters from arguments
Enables SMTP/TLS (STARTTLS) for this object if server accepts. context is a OpenSSL::SSL::SSLContext object.
Ensures hash is a valid Tuple.
The path where installed executables live
Adds an executable named “executable” to spec with the given shebang.
The executable is also written to the bin dir in @tmpdir and the installed gem directory for spec.
Builds the @spec gem and returns an installer for it. The built gem includes:
bin/executable lib/code.rb ext/a/mkrf_conf.rb
Split the Gem search path (as reported by Gem.path).
Adds a runtime dependency named gem with requirements to this gem.
Usage:
spec.add_runtime_dependency 'example', '~> 1.1', '>= 1.1.4'
The version of Ruby required by this gem. The ruby version can be specified to the patch-level:
$ ruby -v -e 'p Gem.ruby_version' ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0] #<Gem::Version "2.0.0.247">
Because patch-level is taken into account, be very careful specifying using ‘<=`: `<= 2.2.2` will not match any patch-level of 2.2.2 after the `p0` release. It is much safer to specify `< 2.2.3` instead
Usage:
# This gem will work with 1.8.6 or greater... spec.required_ruby_version = '>= 1.8.6' # Only with ruby 2.0.x spec.required_ruby_version = '~> 2.0' # Only with ruby between 2.2.0 and 2.2.2 spec.required_ruby_version = ['>= 2.2.0', '< 2.2.3']
