Finds all git gems matching req
Return an array of IndexSpecification objects matching DependencyRequest req.
Returns an array of IndexSpecification objects matching DependencyRequest req.
Returns an Array of IndexSpecification objects matching the DependencyRequest req.
The find_all method must be implemented. It returns all Resolver Specification objects matching the given DependencyRequest req.
Returns an Array of VendorSpecification objects matching the DependencyRequest req.
Returns a new Array formed from self with elements rotated from one end to the other.
When no argument given, returns a new Array that is like self, except that the first element has been rotated to the last position:
a = [:foo, 'bar', 2, 'bar'] a1 = a.rotate a1 # => ["bar", 2, "bar", :foo]
When given a non-negative Integer count, returns a new Array with count elements rotated from the beginning to the end:
a = [:foo, 'bar', 2] a1 = a.rotate(2) a1 # => [2, :foo, "bar"]
If count is large, uses count % array.size as the count:
a = [:foo, 'bar', 2] a1 = a.rotate(20) a1 # => [2, :foo, "bar"]
If count is zero, returns a copy of self, unmodified:
a = [:foo, 'bar', 2] a1 = a.rotate(0) a1 # => [:foo, "bar", 2]
When given a negative Integer count, rotates in the opposite direction, from end to beginning:
a = [:foo, 'bar', 2] a1 = a.rotate(-2) a1 # => ["bar", 2, :foo]
If count is small (far from zero), uses count % array.size as the count:
a = [:foo, 'bar', 2] a1 = a.rotate(-5) a1 # => ["bar", 2, :foo]
Rotates self in place by moving elements from one end to the other; returns self.
When no argument given, rotates the first element to the last position:
a = [:foo, 'bar', 2, 'bar'] a.rotate! # => ["bar", 2, "bar", :foo]
When given a non-negative Integer count, rotates count elements from the beginning to the end:
a = [:foo, 'bar', 2] a.rotate!(2) a # => [2, :foo, "bar"]
If count is large, uses count % array.size as the count:
a = [:foo, 'bar', 2] a.rotate!(20) a # => [2, :foo, "bar"]
If count is zero, returns self unmodified:
a = [:foo, 'bar', 2] a.rotate!(0) a # => [:foo, "bar", 2]
When given a negative Integer count, rotates in the opposite direction, from end to beginning:
a = [:foo, 'bar', 2] a.rotate!(-2) a # => ["bar", 2, :foo]
If count is small (far from zero), uses count % array.size as the count:
a = [:foo, 'bar', 2] a.rotate!(-5) a # => ["bar", 2, :foo]
Calls the block, if given, with each element of self; returns a new Array whose elements are the return values from the block:
a = [:foo, 'bar', 2] a1 = a.map {|element| element.class } a1 # => [Symbol, String, Integer]
Returns a new Enumerator if no block given:
a = [:foo, 'bar', 2] a1 = a.map a1 # => #<Enumerator: [:foo, "bar", 2]:map>
Calls the block, if given, with each element; replaces the element with the block’s return value:
a = [:foo, 'bar', 2] a.map! { |element| element.class } # => [Symbol, String, Integer]
Returns a new Enumerator if no block given:
a = [:foo, 'bar', 2] a1 = a.map! a1 # => #<Enumerator: [:foo, "bar", 2]:map!>
Replaces specified elements in self with specified objects; returns self.
With argument obj and no block given, replaces all elements with that one object:
a = ['a', 'b', 'c', 'd'] a # => ["a", "b", "c", "d"] a.fill(:X) # => [:X, :X, :X, :X]
With arguments obj and Integer start, and no block given, replaces elements based on the given start.
If start is in range (0 <= start < array.size), replaces all elements from offset start through the end:
a = ['a', 'b', 'c', 'd'] a.fill(:X, 2) # => ["a", "b", :X, :X]
If start is too large (start >= array.size), does nothing:
a = ['a', 'b', 'c', 'd'] a.fill(:X, 4) # => ["a", "b", "c", "d"] a = ['a', 'b', 'c', 'd'] a.fill(:X, 5) # => ["a", "b", "c", "d"]
If start is negative, counts from the end (starting index is start + array.size):
a = ['a', 'b', 'c', 'd'] a.fill(:X, -2) # => ["a", "b", :X, :X]
If start is too small (less than and far from zero), replaces all elements:
a = ['a', 'b', 'c', 'd'] a.fill(:X, -6) # => [:X, :X, :X, :X] a = ['a', 'b', 'c', 'd'] a.fill(:X, -50) # => [:X, :X, :X, :X]
With arguments obj, Integer start, and Integer length, and no block given, replaces elements based on the given start and length.
If start is in range, replaces length elements beginning at offset start:
a = ['a', 'b', 'c', 'd'] a.fill(:X, 1, 1) # => ["a", :X, "c", "d"]
If start is negative, counts from the end:
a = ['a', 'b', 'c', 'd'] a.fill(:X, -2, 1) # => ["a", "b", :X, "d"]
If start is large (start >= array.size), extends self with nil:
a = ['a', 'b', 'c', 'd'] a.fill(:X, 5, 0) # => ["a", "b", "c", "d", nil] a = ['a', 'b', 'c', 'd'] a.fill(:X, 5, 2) # => ["a", "b", "c", "d", nil, :X, :X]
If length is zero or negative, replaces no elements:
a = ['a', 'b', 'c', 'd'] a.fill(:X, 1, 0) # => ["a", "b", "c", "d"] a.fill(:X, 1, -1) # => ["a", "b", "c", "d"]
With arguments obj and Range range, and no block given, replaces elements based on the given range.
If the range is positive and ascending (0 < range.begin <= range.end), replaces elements from range.begin to range.end:

If range.last and range.last are both negative, both count from the end of the array:
a = ['a', 'b', 'c', 'd'] a.fill(:X, (-1..-1)) # => ["a", "b", "c", :X] a = ['a', 'b', 'c', 'd'] a.fill(:X, (-2..-2)) # => ["a", "b", :X, "d"]
With no arguments and a block given, calls the block with each index; replaces the corresponding element with the block’s return value:
a = ['a', 'b', 'c', 'd'] a.fill { |index| "new_#{index}" } # => ["new_0", "new_1", "new_2", "new_3"]
With argument start and a block given, calls the block with each index from offset start to the end; replaces the corresponding element with the block’s return value.
If start is in range (0 <= start < array.size), replaces from offset start to the end:
a = ['a', 'b', 'c', 'd'] a.fill(1) { |index| "new_#{index}" } # => ["a", "new_1", "new_2", "new_3"]
If start is too large(start >= array.size), does nothing:

If start is negative, counts from the end:
a = ['a', 'b', 'c', 'd'] a.fill(-2) { |index| "new_#{index}" } # => ["a", "b", "new_2", "new_3"]
If start is too small (start <= -array.size, replaces all elements:

With arguments start and length, and a block given, calls the block for each index specified by start length; replaces the corresponding element with the block’s return value.
If start is in range, replaces length elements beginning at offset start:
a = ['a', 'b', 'c', 'd'] a.fill(1, 1) { |index| "new_#{index}" } # => ["a", "new_1", "c", "d"]
If start is negative, counts from the end:

When invoked with a block, yield all permutations of elements of self; returns self. The order of permutations is indeterminate.
When a block and an in-range positive Integer argument n (0 < n <= self.size) are given, calls the block with all n-tuple permutations of self.
Example:
a = [0, 1, 2] a.permutation(2) {|permutation| p permutation }
Output:
[0, 1] [0, 2] [1, 0] [1, 2] [2, 0] [2, 1]
Another example:
a = [0, 1, 2] a.permutation(3) {|permutation| p permutation }
Output:
[0, 1, 2] [0, 2, 1] [1, 0, 2] [1, 2, 0] [2, 0, 1] [2, 1, 0]
When n is zero, calls the block once with a new empty Array:
a = [0, 1, 2] a.permutation(0) {|permutation| p permutation }
Output:
[]
When n is out of range (negative or larger than self.size), does not call the block:
a = [0, 1, 2] a.permutation(-1) {|permutation| fail 'Cannot happen' } a.permutation(4) {|permutation| fail 'Cannot happen' }
When a block given but no argument, behaves the same as a.permutation(a.size):
a = [0, 1, 2] a.permutation {|permutation| p permutation }
Output:
[0, 1, 2] [0, 2, 1] [1, 0, 2] [1, 2, 0] [2, 0, 1] [2, 1, 0]
Returns a new Enumerator if no block given:
a = [0, 1, 2] a.permutation # => #<Enumerator: [0, 1, 2]:permutation> a.permutation(2) # => #<Enumerator: [0, 1, 2]:permutation(2)>
Returns a new Array containing the first n element of self, where n is a non-negative Integer; does not modify self.
Examples:
a = [0, 1, 2, 3, 4, 5] a.take(1) # => [0] a.take(2) # => [0, 1] a.take(50) # => [0, 1, 2, 3, 4, 5] a # => [0, 1, 2, 3, 4, 5]
Builds a command line string from an argument list array joining all elements escaped for the Bourne shell and separated by a space.
See Shellwords.shelljoin for details.
Returns a Hash containing implementation-dependent counters inside the VM.
This hash includes information about method/constant caches:
{
:constant_cache_invalidations=>2,
:constant_cache_misses=>14,
:global_cvar_state=>27
}
If USE_DEBUG_COUNTER is enabled, debug counters will be included.
The contents of the hash are implementation specific and may be changed in the future.
This method is only expected to work on C Ruby.
Returns the value as a rational. The optional argument eps is always ignored.
Return the class or module refined by the receiver.
module M refine String do end end M.refinements[0].target # => String
Returns a new Complex object formed from the arguments, each of which must be an instance of Numeric, or an instance of one of its subclasses: Complex, Float, Integer, Rational; see Rectangular Coordinates:

Complex.rectangular is an alias for Complex.rect.
Returns the real value for self:
Complex.rect(7).real # => 7 Complex.rect(9, -4).real # => 9
If self was created with polar coordinates, the returned value is computed, and may be inexact:
Complex.polar(1, Math::PI/4).real # => 0.7071067811865476 # Square root of 2.
Returns the array [self.real, self.imag]:
Complex.rect(1, 2).rect # => [1, 2]
If self was created with polar coordinates, the returned value is computed, and may be inexact:
Complex.polar(1.0, 1.0).rect # => [0.5403023058681398, 0.8414709848078965]
Complex#rectangular is an alias for Complex#rect.
Returns false; for compatibility with Numeric#real?.
Returns a Rational object whose value is exactly or approximately equivalent to that of self.real.
With no argument epsilon given, returns a Rational object whose value is exactly equal to that of self.real.rationalize:
Complex.rect(1, 0).rationalize # => (1/1) Complex.rect(1, Rational(0, 1)).rationalize # => (1/1) Complex.rect(3.14159, 0).rationalize # => (314159/100000)
With argument epsilon given, returns a Rational object whose value is exactly or approximately equal to that of self.real to the given precision:
