Types
toTime :: Real a => a -> Rational Source #
Turns a number into a (rational) time value. An alias for toRational.
nextSam :: Time -> Time Source #
The end point of the current cycle (and starting point of the next cycle)
An arc of time, with a start time (or onset) and a stop time (or offset)

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 #
The arc of the whole cycle that the given time value falls within
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
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)
An event is a value that's active during a timespan The part should be equal to or fit inside the whole

compareDefrag :: Ord a => [Event a] -> [Event a] -> Bool Source #
Compares two lists of events, attempting to combine fragmented events in the process
for a truer compare
defragParts :: Eq a => [Event a] -> [Event a] Source #
Returns a list of events, with any adjacent parts of the same whole combined
isAdjacent :: Eq a => Event a -> Event a -> Bool Source #
Returns True if the two given events are adjacent parts of the same whole
eventValue :: Event a -> a Source #
eventHasOnset :: Event a -> Bool Source #
an Arc and some named control values
Also known as Continuous vs Discrete/Amorphous vs Pulsating etc.
A datatype that's basically a query, plus a hint about whether its events are Analogue or Digital by nature

type ControlPattern = Pattern ControlMap Source #
Instances
(<*) :: Pattern (a -> b) -> Pattern a -> Pattern b infixl 4 Source #
Like *, but the structure only comes from the left
(*>) :: Pattern (a -> b) -> Pattern a -> Pattern b infixl 4 Source #
Like *, but the structure only comes from the right
unwrap :: Pattern (Pattern a) -> Pattern a Source #
Turns a pattern of patterns into a single pattern.
(this is actually join)
1/ For query arc, get the events from the outer pattern pp
2/ Query the inner pattern using the part of the outer
3/ For each inner event, set the whole and part to be the intersection
of the outer whole and part, respectively
4 Concatenate all the events together (discarding wholesparts that didn't intersect)
TODO - what if a continuous pattern contains a discrete one, or vice-versa?
innerJoin :: Pattern (Pattern a) -> Pattern a Source #
Turns a pattern of patterns into a single pattern. Like unwrap,
but structure only comes from the inner pattern.
outerJoin :: Pattern (Pattern a) -> Pattern a Source #
Turns a pattern of patterns into a single pattern. Like unwrap,
but structure only comes from the outer pattern.
squeezeJoin :: Pattern (Pattern a) -> Pattern a Source #
Like unwrap, but cycles of the inner patterns are compressed to fit the
timespan of the outer whole (or the original query if it's a continuous pattern?)
TODO - what if a continuous pattern contains a discrete one, or vice-versa?

Internal functions
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
filterOnsets :: Pattern a -> Pattern a Source #
