See Net::HTTPGenericRequest for attributes and methods.

Gem::Resolver::Molinillo is a generic dependency resolution algorithm.

Returns a new Array containing those elements from self that are not duplicates, the first occurrence always being retained.

With no block given, identifies and omits duplicates using method eql? to compare.

a = [0, 0, 1, 1, 2, 2]
a.uniq # => [0, 1, 2]

With a block given, calls the block for each element; identifies (using method eql?) and omits duplicate values, that is, those elements for which the block returns the same value:

a = ['a', 'aa', 'aaa', 'b', 'bb', 'bbb']
a.uniq {|element| element.size } # => ["a", "aa", "aaa"]

With no block, returns a new array containing only unique elements; the array has no two elements e0 and e1 such that e0.eql?(e1):

%w[a b c c b a a b c].uniq       # => ["a", "b", "c"]
[0, 1, 2, 2, 1, 0, 0, 1, 2].uniq # => [0, 1, 2]

With a block, returns a new array containing only for which the block returns a unique value:

a = [0, 1, 2, 3, 4, 5, 5, 4, 3, 2, 1]
a.uniq {|i| i.even? ? i : 0 } # => [0, 2, 4]
a = %w[a b c d e e d c b a a b c d e]
a.uniq {|c| c < 'c' }         # => ["a", "c"]

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

Returns a new Array that is the union of self and all given Arrays other_arrays; duplicates are removed; order is preserved; items are compared using eql?:

[0, 1, 2, 3].union([4, 5], [6, 7]) # => [0, 1, 2, 3, 4, 5, 6, 7]
[0, 1, 1].union([2, 1], [3, 1]) # => [0, 1, 2, 3]
[0, 1, 2, 3].union([3, 2], [1, 0]) # => [0, 1, 2, 3]

Returns a copy of self if no arguments given.

Return a Regexp object that is the union of the given patterns, i.e., will match any of its parts. The patterns can be Regexp objects, in which case their options will be preserved, or Strings. If no patterns are given, returns /(?!)/. The behavior is unspecified if any given pattern contains capture.

Regexp.union                         #=> /(?!)/
Regexp.union("penzance")             #=> /penzance/
Regexp.union("a+b*c")                #=> /a\+b\*c/
Regexp.union("skiing", "sledding")   #=> /skiing|sledding/
Regexp.union(["skiing", "sledding"]) #=> /skiing|sledding/
Regexp.union(/dogs/, /cats/i)        #=> /(?-mix:dogs)|(?i-mx:cats)/

Note: the arguments for ::union will try to be converted into a regular expression literal via to_regexp.

creates a new socket connected to path using UNIX socket socket.

If a block is given, the block is called with the socket. The value of the block is returned. The socket is closed when this method returns.

If no block is given, the socket is returned.

# talk to /tmp/sock socket.
Socket.unix("/tmp/sock") {|sock|
  t = Thread.new { IO.copy_stream(sock, STDOUT) }
  IO.copy_stream(STDIN, sock)
  t.join
}

returns an addrinfo object for UNIX socket address.

socktype specifies the socket type. If it is omitted, :STREAM is used.

Addrinfo.unix("/tmp/sock")         #=> #<Addrinfo: /tmp/sock SOCK_STREAM>
Addrinfo.unix("/tmp/sock", :DGRAM) #=> #<Addrinfo: /tmp/sock SOCK_DGRAM>

returns true if addrinfo is UNIX address. returns false otherwise.

Addrinfo.tcp("127.0.0.1", 80).unix? #=> false
Addrinfo.tcp("::1", 80).unix?       #=> false
Addrinfo.unix("/tmp/sock").unix?    #=> true

Returns true if coverage stats are currently being collected (after Coverage.start call, but before Coverage.result call)

Returns true for IPv6 unique local address (fc00::/7, RFC4193). It returns false otherwise.

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