This module is the entry-point for converting a prism syntax tree into the seattlerb/ruby_parser gem’s syntax tree.
Returns a new 2-element Array containing the minimum and maximum values from self, either per method <=> or per a given block:.
When no block is given, each element in self must respond to method <=> with an Integer; returns a new 2-element Array containing the minimum and maximum values from self, per method <=>:
[0, 1, 2].minmax # => [0, 2]
When a block is given, the block must return an Integer; the block is called self.size-1 times to compare elements; returns a new 2-element Array containing the minimum and maximum values from self, per the block:
['0', '00', '000'].minmax {|a, b| a.size <=> b.size } # => ["0", "000"]
Returns a 2-element array containing the minimum and maximum value in self, either according to comparison method <=> or a given block.
With no block given, returns the minimum and maximum values, using <=> for comparison:
(1..4).minmax # => [1, 4] (1...4).minmax # => [1, 3] ('a'..'d').minmax # => ["a", "d"] (-4..-1).minmax # => [-4, -1]
With a block given, the block must return an integer:
Negative if a is smaller than b.
Zero if a and b are equal.
Positive if a is larger than b.
The block is called self.size times to compare elements; returns a 2-element Array containing the minimum and maximum values from self, per the block:
(1..4).minmax {|a, b| -(a <=> b) } # => [4, 1]
Returns [nil, nil] if:
The begin value of the range is larger than the end value:
(4..1).minmax # => [nil, nil] (4..1).minmax {|a, b| -(a <=> b) } # => [nil, nil]
The begin value of an exclusive range is equal to the end value:
(1...1).minmax # => [nil, nil] (1...1).minmax {|a, b| -(a <=> b) } # => [nil, nil]
Raises an exception if self is a beginless or an endless range.
Returns a 2-element array containing the minimum and maximum elements according to a given criterion. The ordering of equal elements is indeterminate and may be unstable.
With no argument and no block, returns the minimum and maximum elements, using the elements’ own method <=> for comparison:
(1..4).minmax # => [1, 4] (-4..-1).minmax # => [-4, -1] %w[d c b a].minmax # => ["a", "d"] {foo: 0, bar: 1, baz: 2}.minmax # => [[:bar, 1], [:foo, 0]] [].minmax # => [nil, nil]
With a block given, returns the minimum and maximum elements as determined by the block:
%w[xxx x xxxx xx].minmax {|a, b| a.size <=> b.size } # => ["x", "xxxx"] h = {foo: 0, bar: 1, baz: 2} h.minmax {|pair1, pair2| pair1[1] <=> pair2[1] } # => [[:foo, 0], [:baz, 2]] [].minmax {|a, b| a <=> b } # => [nil, nil]
Returns the maximum number of group IDs allowed in the supplemental group access list:
Process.maxgroups # => 32
Sets the maximum number of group IDs allowed in the supplemental group access list.
Sets the maximum size of the queue to the given number.

Deprecation method to deprecate Rubygems commands
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!>
Returns the remainder after dividing self by other.
Examples:
11.remainder(4) # => 3 11.remainder(-4) # => 3 -11.remainder(4) # => -3 -11.remainder(-4) # => -3 12.remainder(4) # => 0 12.remainder(-4) # => 0 -12.remainder(4) # => 0 -12.remainder(-4) # => 0 13.remainder(4.0) # => 1.0 13.remainder(Rational(4, 1)) # => (1/1)
Returns the imaginary value for self:
Complex.rect(7).imag # => 0 Complex.rect(9, -4).imag # => -4
If self was created with polar coordinates, the returned value is computed, and may be inexact:
Complex.polar(1, Math::PI/4).imag # => 0.7071067811865476 # Square root of 2.
Returns the imaginary value for self:
Complex.rect(7).imag # => 0 Complex.rect(9, -4).imag # => -4
If self was created with polar coordinates, the returned value is computed, and may be inexact:
Complex.polar(1, Math::PI/4).imag # => 0.7071067811865476 # Square root of 2.
Returns the absolute value (magnitude) for self; see polar coordinates:
Complex.polar(-1, 0).abs # => 1.0
If self was created with rectangular coordinates, the returned value is computed, and may be inexact:
Complex.rectangular(1, 1).abs # => 1.4142135623730951 # The square root of 2.
Returns the remainder after dividing self by other.
Of the Core and Standard Library classes, only Float and Rational use this implementation.
Examples:
11.0.remainder(4) # => 3.0 11.0.remainder(-4) # => 3.0 -11.0.remainder(4) # => -3.0 -11.0.remainder(-4) # => -3.0 12.0.remainder(4) # => 0.0 12.0.remainder(-4) # => 0.0 -12.0.remainder(4) # => -0.0 -12.0.remainder(-4) # => -0.0 13.0.remainder(4.0) # => 1.0 13.0.remainder(Rational(4, 1)) # => 1.0 Rational(13, 1).remainder(4) # => (1/1) Rational(13, 1).remainder(-4) # => (1/1) Rational(-13, 1).remainder(4) # => (-1/1) Rational(-13, 1).remainder(-4) # => (-1/1)
Returns the absolute value of self.
12.abs #=> 12 (-34.56).abs #=> 34.56 -34.56.abs #=> 34.56
Returns zero.
Returns a MatchData object (or nil) based on self and the given pattern.
Note: also updates Global Variables at Regexp.
Computes regexp by converting pattern (if not already a Regexp).
regexp = Regexp.new(pattern)
Computes matchdata, which will be either a MatchData object or nil (see Regexp#match):
matchdata = <tt>regexp.match(self)
With no block given, returns the computed matchdata:
'foo'.match('f') # => #<MatchData "f"> 'foo'.match('o') # => #<MatchData "o"> 'foo'.match('x') # => nil
If Integer argument offset is given, the search begins at index offset:
'foo'.match('f', 1) # => nil 'foo'.match('o', 1) # => #<MatchData "o">
With a block given, calls the block with the computed matchdata and returns the block’s return value:
'foo'.match(/o/) {|matchdata| matchdata } # => #<MatchData "o"> 'foo'.match(/x/) {|matchdata| matchdata } # => nil 'foo'.match(/f/, 1) {|matchdata| matchdata } # => nil
