Text.Show.Prettyprint.Diagnostic

Description

These functions are identical to the ones in the main module, but instead of falling back to the un-prettyprinted input, they will report an error on failure.

>>> putStrLn (prettifyShowErr "Imbalanced (Parenthesis)) here")
ERROR (interactive):1:25: error: expected: char literal,
    end of input, identifier, list,
    number, record, string literal,
    tuple, unit
Imbalanced (Parenthesis)) here<EOF>
                        ^
