Adds sort_alphabetical and sort_alphabetical_by to Enumberable(Array/Hash...), which sorts UTF8 Strings alphabetical. This sorting is done by placing variants on the same level as base character (A comes before Ä but ÄA comes before AB).

Setup

• As Rails plugin: rails plugin install git:/grosser/sort_alphabetical.git
• As gem: sudo gem install sort_alphabetical

Usage

['b','á'].sort_alphabetical == ['á','b']
[['b',1],['á',2]].sort_alphabetical_by(&:first) == [['á',2],['b',1]]

SortAlphabetical.to_ascii('á') == 'a'

TODO

• fix specs for 1.9
• Sort non-ascii-convertables like ß(ss), œ(oe) , fi(fi), see Ligatures
• Integrate natural sorting e.g. ['a11', 'a2'] => ['a2', 'a11'] like NaturalSort

Authors

• original string_to_ascii: Marc-Andre.
