Documentation
usortOn :: Ord b => (a -> b) -> [a] -> [a] Source
Sort and remove duplicates wrt some custom ordering
duplicates :: Ord a => [a] -> [a] Source
Returns the duplicates in a list
flattenComponent :: Component a -> [a] Source
components :: Ord name => (thing -> name) -> (thing -> [name]) -> [thing] -> [Component thing] Source
Strongly connected components
sortThings :: Ord name => (thing -> name) -> (thing -> [name]) -> [thing] -> [[thing]] Source
Sort things in topologically in strongly connected components
flagify :: String -> String Source
Makes a nice flag from a constructor string
> flagify "PrintPolyFOL" "print-poly-fol"
flagifyShow :: Show a => a -> String Source
Makes a flag from something Show-able
maximumOn :: forall f a b. (Foldable f, Ord b) => (a -> b) -> f a -> b Source
Calculates the maximum value of a foldable value.
withPrevious :: [a] -> [(a, [a])] Source
Pair up a list with its previous elements
withPrevious "abc" = [('a',""),('b',"a"),('c',"ab")]
