Relude.Debug

Functions for debugging. If you left these functions in your code then a warning is generated to remind you about left usages. Also some functions (and data types) are convenient for prototyping.

Tracing

trace :: String -> a -> a

Warning: trace remains in code

Version of trace that leaves warning.

traceM :: Applicative f => String -> f ()

Warning: traceM remains in code

Version of traceM that leaves warning.

traceId :: String -> String

Warning: traceId remains in code

Version of traceId that leaves warning.

traceShow :: Show a => a -> b -> b

Warning: traceShow remains in code

Version of traceShow that leaves warning.

traceShowId :: Show a => a -> a

Warning: traceShowId remains in code

Version of traceShowId that leaves warning.

traceShowM :: (Show a, Applicative f) => a -> f ()

Warning: traceShowM remains in code

Version of traceShowM that leaves warning.

Imprecise error

error :: forall (r :: RuntimeRep). forall (a :: TYPE r). HasCallStack => Text -> a

error that takes Text as an argument.

data Undefined

Warning: Undefined type remains in code

Similar to undefined but data type.
