Builds extensions. Valid types of extensions are extconf.rb files, configure scripts and rakefiles or mkrf_conf files.
Returns the path to the trusted certificate
Returns true
@return [Symbol] The name of the action.
Adds the given action to the log, running the action @param [DependencyGraph] graph @param [Action] action @return The value returned by ‘action.up`
Ends the resolution process @return [void]
Appends the elements of +other_ary+s to self.
[ "a", "b" ].concat( ["c", "d"] ) #=> [ "a", "b", "c", "d" ] [ "a" ].concat( ["b"], ["c", "d"] ) #=> [ "a", "b", "c", "d" ] [ "a" ].concat #=> [ "a" ] a = [ 1, 2, 3 ] a.concat( [ 4, 5 ] ) a #=> [ 1, 2, 3, 4, 5 ] a = [ 1, 2 ] a.concat(a, a) #=> [1, 2, 1, 2, 1, 2]
See also Array#+.
Inserts the given values before the element with the given index.
Negative indices count backwards from the end of the array, where -1 is the last element. If a negative index is used, the given values will be inserted after that element, so using an index of -1 will insert the values at the end of the array.
a = %w{ a b c d } a.insert(2, 99) #=> ["a", "b", 99, "c", "d"] a.insert(-2, 1, 2, 3) #=> ["a", "b", 99, "c", 1, 2, 3, "d"]
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.
ary = [ "d", "a", "e", "c", "b" ] ary.sort #=> ["a", "b", "c", "d", "e"] ary.sort { |a, b| b <=> a } #=> ["e", "d", "c", "b", "a"]

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.
ary = [ "d", "a", "e", "c", "b" ] ary.sort! #=> ["a", "b", "c", "d", "e"] ary.sort! { |a, b| b <=> a } #=> ["e", "d", "c", "b", "a"]
