Class: ENV

Passes each element of the collection to the given block.

Passes each element of the collection to the given block.

Passes each element of the collection to the given block.

Passes each element of the collection to the given block.

Enumerates over the items, chunking them together based on the return value of the block.

Creates an enumerator for each chunked elements.

Alias for Enumerable#map.

Alias for Enumerable#flat_map.

Returns the number of items in enum through enumeration.

Calls block for each element of enum repeatedly n times or forever if none or nil is given.

Alias for Enumerable#find.

Drops first n elements from enum, and returns rest elements in an array.

Drops elements up to, but not including, the first element for which the block returns nil or false and returns an array containing the remaining elements.

Iterates the given block for each array of consecutive <n> elements.

Calls block once for each element in self, passing that element as a parameter, converting multiple values from yield to an array.

Iterates the given block for each slice of <n> elements.

Calls block with two arguments, the item and its index, for each item in enum.

Iterates the given block for each element with an arbitrary object given, and returns the initially given object.

Alias for Enumerable#to_a.

Passes each entry in enum to block.

Alias for Enumerable#select.

Compares each entry in enum with value or passes to block.

Returns the first element, or the first n elements, of the enumerable.

Returns a new array with the concatenated results of running block once for every element in enum.

Returns an array of every element in enum for which Pattern === element.

Inverted version of Enumerable#grep.

Groups the collection by result of the block.

Alias for Enumerable#member?.

Combines all elements of enum by applying a binary operation, specified by a block or a symbol that names a method or operator.

Returns a lazy enumerator, whose methods map/collect, flat_map/collect_concat, select/find_all, reject, grep, grep_v, zip, take, take_while, drop, and drop_while enumerate values only on an as-needed basis.

Returns a new array with the results of running block once for every element in enum.

Returns the object in enum with the maximum value.

Returns the object in enum that gives the maximum value from the given block.

Returns true if any member of enum equals obj.

Returns the object in enum with the minimum value.

Returns the object in enum that gives the minimum value from the given block.

Returns a two element array which contains the minimum and the maximum value in the enumerable.

Returns a two element array containing the objects in enum that correspond to the minimum and maximum values respectively from the given block.

Returns two arrays, the first containing the elements of enum for which the block evaluates to true, the second containing the rest.

Alias for Enumerable#inject.

Returns an array for all elements of enum for which the given block returns false.

Builds a temporary array and traverses that array in reverse order.

Returns an array containing all elements of enum for which the given block returns a true value.

Creates an enumerator for each chunked elements.

Creates an enumerator for each chunked elements.

Creates an enumerator for each chunked elements.

Returns an array containing the items in enum sorted, either according to their own <=> method, or by using the results of the supplied block.

Sorts enum using a set of keys generated by mapping the values in enum through the given block.

Returns first n elements from enum.

Passes elements to the block until the block returns nil or false, then stops iterating and returns an array of all prior elements.

Returns an array containing the items in enum.

Returns the result of interpreting enum as a list of [key, value] pairs.

Takes one element from enum and merges corresponding elements from each args.
