Data.Progress

Progress estimates.

progress is good for functions the recursion trees of which are very unbalanced. progressWithCalls is good for functions that consume their input very long before they finish.

Documentation

progress :: Data s => (s -> IO b) -> s -> IO b

Estimate progress based on thunks forced.

progressWithFile :: (Handle -> IO b) -> Handle -> IO b

...based on amount of file consumed.

progressWithCalls :: ((t -> IO b) -> t -> IO b) -> t -> IO b

...based on number of recursive calls.

It returns a result equivalent to that of fix f x.

progress' :: Data s => (s -> b) -> s -> IO b

Adapters for pure functions.

progressWithCalls' :: ((a -> c) -> a -> c) -> a -> IO c
