Module Spruz::Minimize
In: lib/spruz/minimize.rb

This module can be mixed into all classes, whose instances respond to the

and size-methods, like for example Array. The returned elements from []

should respond to the succ method.

Methods

Public Instance methods

Returns a minimized version of this object, that is successive elements are substituted with ranges a..b. In the situation …, x, y,… and y != x.succ a range x..x is created, to make it easier to iterate over all the ranges in one run. A small example:

 [ 'A', 'B', 'C', 'G', 'K', 'L', 'M' ].minimize # => [ 'A'..'C', 'G'..'G', 'K'..'M' ]

If the order of the original elements doesn‘t matter, it‘s a good idea to first sort them and then minimize:

 [ 5, 1, 4, 2 ].sort.minimize # => [ 1..2, 4..5 ]

First minimizes this object, then calls the replace method with the result.

Invert a minimized version of an object. Some small examples:

 [ 'A'..'C', 'G'..'G', 'K'..'M' ].unminimize # => [ 'A', 'B', 'C', 'G', 'K', 'L', 'M' ]

and

 [ 1..2, 4..5 ].unminimize # => [ 1, 2, 4, 5 ]

Invert a minimized version of this object in place.
