unknown :: Traceable a => String -> Traced a Source

Create a named thing with no value. Cannot be used where a real value is needed.

tracedD :: Traceable a => Traced a -> TracedD Source

Extract the expression tree from a traced value.

data TraceLevel Source

class (Typeable a, Show a) => Traceable a where Source

trPPrint :: TraceLevel -> Int -> a -> Doc Source

Expression tree for a traced value.

unTracedD :: Traceable a => TracedD -> Maybe (Traced a) Source

Convert an expression tree to a traced value, if the types are correct.

binOp :: (Traceable a, Traceable b, Traceable c) => (a -> b -> c) -> (String, Fixity) -> Traced a -> Traced b -> Traced c Source

apply :: Traceable a => a -> Name -> Fixity -> [TracedD] -> Traced a Source

Create a traced value with an `Apply`

expression tree.

Fixity for identifier.

showAsExpFull :: Traceable a => Traced a -> String Source

Show the expression tree of a traced value, also show the value of each variable.

pPrintTraced :: Traceable a => TraceLevel -> Int -> Traced a -> Doc Source
