Returns a JSON string representing self:
require 'json/add/symbol' puts :foo.to_json
Output:
# {"json_class":"Symbol","s":"foo"}
Return the path as a String.
to_path is implemented so Pathname objects are usable with File.open, etc.
creates a socket connected to remote_addr_args and bound to self.
The optional last argument opts is options represented by a hash. opts may have following options:
specify the timeout in seconds.
If a block is given, it is called with the socket and the value of the block is returned. The socket is returned otherwise.
Addrinfo.tcp("0.0.0.0", 4649).connect_to("www.ruby-lang.org", 80) {|s| s.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n" puts s.read }
Returns self.
Returns a Hash containing all name/value pairs from ENV:
ENV.replace('foo' => '0', 'bar' => '1') ENV.to_hash # => {"bar"=>"1", "foo"=>"0"}
Returns an IO object representing the current file. This will be a File object unless the current file is a stream such as STDIN.
For example:
ARGF.to_io #=> #<File:glark.txt> ARGF.to_io #=> #<IO:<STDIN>>
Returns a string containing the IP address representation in canonical form.
Returns a json string containing the IP address representation.
Creates a Range object for the network address.
Makes a set from the enumerable object with given arguments. Needs to require "set" to use this method.
Dump Ruby object to a JSON string.
Calculates relative path to oth from self.
require 'uri' uri = URI.parse('http://my.example.com') uri.route_to('http://my.example.com/main.rbx?page=1') #=> #<URI::Generic /main.rbx?page=1>
Returns the system-dependent integer status of self:
`cat /nop` $?.to_i # => 256
Returns a string representation of self:
`cat /nop` $?.to_s # => "pid 1262141 exit 1"
DO NOT USE THIS DIRECTLY.
Hook method to return whether the obj can respond to id method or not.
When the method name parameter is given as a string, the string is converted to a symbol.
See respond_to?, and the example of BasicObject.
Returns IPv4 address of IPv4 mapped/compatible IPv6 address. It returns nil if self is not IPv4 mapped/compatible IPv6 address.
Addrinfo.ip("::192.0.2.3").ipv6_to_ipv4 #=> #<Addrinfo: 192.0.2.3> Addrinfo.ip("::ffff:192.0.2.3").ipv6_to_ipv4 #=> #<Addrinfo: 192.0.2.3> Addrinfo.ip("::1").ipv6_to_ipv4 #=> nil Addrinfo.ip("192.0.2.3").ipv6_to_ipv4 #=> nil Addrinfo.unix("/tmp/sock").ipv6_to_ipv4 #=> nil
Returns IO instance tied to ARGF for writing if inplace mode is enabled.
Checks for a method provided by this the delegate object by forwarding the call through _getobj_.
Expands lazy enumerator to an array. See Enumerable#to_a.
