Module: OutroRails::VoicingSeedWriter

Included in:

Defined in:

lib/outro_rails/generators/voicing_seed_writer.rb

Overview

Shared behavior for generators that write chord-voicing seed YAML from a chord entry (a hash loaded from db/seeds/chords/*.yml): the chord readers, the slash-symbol rule, and the entry envelope every voicing shares.
