A Ruby implementation of metrics described in Larry Polansky's article Morphological Metrics--henceforth referred to as MM in this documentation-- available here: http://eamusic.dartmouth.edu/~larry/mutationsFAQ.html Plus some lucky bonus AI stuff. In development. This is so pre-alpha. Don't even use this. --- Here's a list of things that needs to happen before you should use this: Functionality - Should this library have these search functions, or should they be split into another library? Is there a standard for doing this in Ruby already? - Angle. What the hell to do with angle. Combinatorial angle? - Implement a wider variety of possibilities for adjacency functions, esp. the notion of a variable adjacency interval. Test coverage - Additional tests for all of the metrics supplied in MM. - Tests for important utility functions. - Test for multimetrics. - Test search functions. Documentation - Improved comments + Better description of what different scaling methods do in different contexts. Example code - Should have a brief tutorial based on MM which walks through the composition of a short piece of music. - Possibly also a scientific computing example. License - Decide what license to use. Code cleanliness - Think about this
