isSubsequenceOf :: Eq a => [a] -> [a] -> Boolbasic-prelude BasicPrelude The isSubsequenceOf function takes two lists and returns True if all the elements of the first list occur, in order, in the second. The elements do not have to occur consecutively. isSubsequenceOf x y is equivalent to x `elem` (subsequences y). Note: isSubsequenceOf is often used in infix form.
Examples
>>> "GHC" `isSubsequenceOf` "The Glorious Haskell Compiler" True
>>> ['a','d'..'z'] `isSubsequenceOf` ['a'..'z'] True
>>> [1..10] `isSubsequenceOf` [10,9..0] False
For the result to be True, the first list must be finite; for the result to be False, the second list must be finite:>>> [0,2..10] `isSubsequenceOf` [0..] True
>>> [0..] `isSubsequenceOf` [0,2..10] False
>>> [0,2..] `isSubsequenceOf` [0..] * Hangs forever*

basic-prelude BasicPrelude The subsequences function returns the list of all subsequences of the argument.
Laziness
subsequences does not look ahead unless it must:>>> take 1 (subsequences undefined) [[]] >>> take 2 (subsequences ('a' : undefined)) ["","a"]Examples
>>> subsequences "abc" ["","a","b","ab","c","ac","bc","abc"]
This function is productive on infinite inputs:>>> take 8 $ subsequences ['a'..] ["","a","b","ab","c","ac","bc","abc"]
eventGetEventSequence :: (HasCallStack, MonadIO m, IsEvent a) => a -> m EventSequencegi-gdk4 GI.Gdk.Objects.Event Returns the event sequence to which the event belongs. Related touch events are connected in a sequence. Other events typically don't have event sequence information.
module GI.Gdk.Structs.
EventSequence GdkEventSequence is an opaque type representing a sequence of related touch events.
