]

note = ccs.notes[1]
note.text            # => "锅炉高能点火器入 {ccs-code}"
note.ccs_code        # => "T37"
note.ccs.description # => "点火装置"

# Fetch by code
ccs = Cnccs.fetch "J98"
ccs.description_full # => "机械；活塞式内燃机与其他动力设备：锅炉及其辅助设备"

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
