type Time = Rational Source #

Time is rational

Turns a number into a (rational) time value. An alias for toRational.

nextSam :: Time -> Time Source #

cyclePos :: Time -> Time Source #

The position of a time value relative to the start of its cycle.

sect :: Arc -> Arc -> Arc Source #

hull :: Arc -> Arc -> Arc Source #

convex hull union

subArc :: Arc -> Arc -> Maybe Arc Source #

subArc i j is the timespan that is the intersection of i and j. intersection The definition is a bit fiddly as results might be zero-width, but not at the end of an non-zero-width arc - e.g. (0,1) and (1,2) do not intersect, but (1,1) (1,1) does.

timeToCycleArc :: Time -> Arc Source #

cycleArc :: Arc -> Arc Source #

Shifts an arc to the equivalent one that starts during cycle zero

cyclesInArc :: Integral a => Arc -> [a] Source #

A list of cycle numbers which are included in the given arc

cycleArcsInArc :: Arc -> [Arc] Source #

A list of arcs of the whole cycles which are included in the given arc

arcCycles :: Arc -> [Arc] Source #

Splits the given ArcF into a list of ArcFs, at cycle boundaries.

arcCyclesZW :: Arc -> [Arc] Source #

Like arcCycles, but returns zero-width arcs

mapCycle :: (Time -> Time) -> Arc -> Arc Source #

Similar to fmap but time is relative to the cycle (i.e. the sam of the start of the arc)

isIn :: Arc -> Time -> Bool Source #

isIn a t is True if t is inside the arc represented by a.

Internal functions

queryArc :: Pattern a -> Arc -> [Event a] Source #

splitQueries :: Pattern a -> Pattern a Source #

Splits queries that span cycles. For example `query p (0.5, 1.5)` would be turned into two queries, `(0.5,1)` and `(1,1.5)`, and the results combined. Being able to assume queries don't span cycles often makes transformations easier to specify.

withResultArc :: (Arc -> Arc) -> Pattern a -> Pattern a Source #

Apply a function to the arcs/timespans (both whole and parts) of the result

withResultTime :: (Time -> Time) -> Pattern a -> Pattern a Source #

Apply a function to the time (both start and end of the timespans of both whole and parts) of the result

withQueryArc :: (Arc -> Arc) -> Pattern a -> Pattern a Source #

Apply a function to the timespan of the query

withQueryTime :: (Time -> Time) -> Pattern a -> Pattern a Source #

Apply a function to the time (both start and end) of the query

withEvent :: (Event a -> Event b) -> Pattern a -> Pattern b Source #

withEvent f p returns a new Pattern with each event mapped over function f.

withEvents :: ([Event a] -> [Event b]) -> Pattern a -> Pattern b Source #

withEvent f p returns a new Pattern with f applied to the resulting list of events for each query function f.

withPart :: (Arc -> Arc) -> Pattern a -> Pattern a Source #

withPart f p returns a new Pattern with function f applied to the part.

applyFIS :: (Double -> Double) -> (Int -> Int) -> (String -> String) -> Value -> Value Source #

Apply one of three functions to a Value, depending on its type

fNum2 :: (Int -> Int -> Int) -> (Double -> Double -> Double) -> Value -> Value -> Value Source #

Apply one of two functions to a Value, depending on its type (int or float; strings and rationals are ignored)

rotL :: Time -> Pattern a -> Pattern a Source #

Shifts a pattern back in time by the given amount, expressed in cycles

rotR :: Time -> Pattern a -> Pattern a Source #

Shifts a pattern forward in time by the given amount, expressed in cycles

Event filters

filterValues :: (a -> Bool) -> Pattern a -> Pattern a Source #

Remove events from patterns that to not meet the given test

filterJust :: Pattern (Maybe a) -> Pattern a Source #

Turns a pattern of Maybe values into a pattern of values, dropping the events of Nothing.
