#RepeatState Source

type RepeatState = { current :: Section, sections :: Sections }

the current repeat state

#initialRepeatState Source

initialRepeatState :: RepeatState

initial repeats i.e. no repeats yet

#indexBar Source

indexBar :: (Maybe Int) -> (Maybe Repeat) -> Int -> RepeatState -> RepeatState

index a bar by identifying any repeat markings and saving the marking against the bar number

#finalBar Source
