Return a String indicating who caused this request to be added (only valid for implicit requests)
Returns true if this gem is installable for the current platform.
Returns true if this gem is installable for the current platform.
Returns true if this specification is installable on this platform.
Is there a path from ‘other` to `self` following edges in the dependency graph? @return true iff there is a path following edges within this {#graph}
Returns the generator of the group.
See the OpenSSL documentation for EC_GROUP_get0_generator()
Returns the cofactor of the group.
See the OpenSSL documentation for EC_GROUP_get_cofactor()
Returns self.
If called on a subclass of Array, converts the receiver to an Array object.
Returns the result of interpreting ary as an array of [key, value] pairs.
[[:foo, :bar], [1, 2]].to_h # => {:foo => :bar, 1 => 2}
Returns the first element, or the first n elements, of the array. If the array is empty, the first form returns nil, and the second form returns an empty array. See also Array#last for the opposite effect.
a = [ "q", "r", "s", "t" ] a.first #=> "q" a.first(2) #=> ["q", "r"]
Returns the last element(s) of self. If the array is empty, the first form returns nil.
See also Array#first for the opposite effect.
a = [ "w", "x", "y", "z" ] a.last #=> "z" a.last(2) #=> ["y", "z"]
Returns a new array containing self‘s elements in reverse order.
[ "a", "b", "c" ].reverse #=> ["c", "b", "a"] [ 1 ].reverse #=> [1]
Reverses self in place.
a = [ "a", "b", "c" ] a.reverse! #=> ["c", "b", "a"] a #=> ["c", "b", "a"]
Returns a new array created by sorting self.
Comparisons for the sort will be done using the <=> operator or using an optional code block.
The block must implement a comparison between a and b and return an integer less than 0 when b follows a, 0 when a and b are equivalent, or an integer greater than 0 when a follows b.
The result is not guaranteed to be stable. When the comparison of two elements returns 0, the order of the elements is unpredictable.
a = [ "d", "a", "e", "c", "b" ] a.sort #=> ["a", "b", "c", "d", "e"] a.sort { |x,y| y <=> x } #=> ["e", "d", "c", "b", "a"]
See also Enumerable#sort_by.
Sorts self in place.
Comparisons for the sort will be done using the <=> operator or using an optional code block.
The block must implement a comparison between a and b and return an integer less than 0 when b follows a, 0 when a and b are equivalent, or an integer greater than 0 when a follows b.
The result is not guaranteed to be stable. When the comparison of two elements returns 0, the order of the elements is unpredictable.
a = [ "d", "a", "e", "c", "b" ] a.sort! #=> ["a", "b", "c", "d", "e"] a.sort! { |x,y| y <=> x } #=> ["e", "d", "c", "b", "a"]
See also Enumerable#sort_by.
Returns a new array containing the items in self for which the given block is not true. The ordering of non-rejected elements is maintained.
See also Array#delete_if
If no block is given, an Enumerator is returned instead.
Deletes every element of self for which the block evaluates to true, if no changes were made returns nil.
The array may not be changed instantly every time the block is called.
See also Enumerable#reject and Array#delete_if.
If no block is given, an Enumerator is returned instead.
Replaces the contents of self with the contents of other_ary, truncating or expanding if necessary.
a = [ "a", "b", "c", "d", "e" ] a.replace([ "x", "y", "z" ]) #=> ["x", "y", "z"] a #=> ["x", "y", "z"]
Creates a string representation of self.
[ "a", "b", "c" ].to_s #=> "[\"a\", \"b\", \"c\"]"
Calculates the set of unambiguous abbreviations for the strings in self.
require 'abbrev' %w{ car cone }.abbrev #=> {"car"=>"car", "ca"=>"car", "cone"=>"cone", "con"=>"cone", "co"=>"cone"}
The optional pattern parameter is a pattern or a string. Only input strings that match the pattern or start with the string are included in the output hash.
%w{ fast boat day }.abbrev(/^.a/) #=> {"fast"=>"fast", "fas"=>"fast", "fa"=>"fast", "day"=>"day", "da"=>"day"} Abbrev.abbrev(%w{car box cone}, "ca") #=> {"car"=>"car", "ca"=>"car"}
See also Abbrev.abbrev
Returns a Digest subclass by name in a thread-safe manner even when on-demand loading is involved.
require 'digest' Digest("MD5") # => Digest::MD5 Digest(:SHA256) # => Digest::SHA256 Digest(:Foo) # => LoadError: library not found for class Digest::Foo -- digest/foo
