data-pprint: Prettyprint and compare Data values

Prettyprint and compare Data values.

• Size limit for the output

• Time limit for the computation

• Escape exceptions

• Do not escape unicode characters

• Comparison: Highlight the first difference

• Comparison: Yes, No or Maybe results

Probably you need only the pprint and (===) functions from the Data.PPrint module.

Usage examples:

pprint [1..] pprint $ repeat [1..] pprint $ iterate (*10) 1 pprint $ map length $ replicate 5 [1..] ++ repeat [] pprint [2 `div` 0, error "xxx", 18, 4 `div` 0] [1..10] === reverse [10,9..1] [1..10] === reverse [10..1] reverse [10..] === [1..] [1..] === [1..99] ++ [101..] ([1..], [1..]) === ([1..], [1..100]) (error "x", [1..]) === (0 `div` 0, reverse [1..]) error ("xx" ++ show (length [1..])) === 1 error ("xx" ++ error "yy") === 1 (error $ unlines $ replicate 300 "xxxxxxxxxxxxxxxxxxxxxxxxxxx") === 1 pprint ['a'..] pprint $ "hello" ++ [error "x"] ++ "world!"
