libghc-groom-prof - 0.1.2.1-2 main

Automatically derived Show instances are an easy way
to inspect data in your program. However, for large
data-structures, the resulting output lacks
whitespace, making it unreadable. Groom offers an
replacement to `show' called `groom' which attempts
to pretty-print the output of `show'. For example:
.
> let x = parseExp "foobar 1 [1,2]"
> in do
> putStrLn (show x)
> putStrLn (groom x)
.
results in:
.
> ParseOk (App (App (Var (UnQual (Ident "foobar"))) (Lit (Int 1))) (List [Lit (Int 1),Lit (Int 2)]))
> ParseOk
> (App (App (Var (UnQual (Ident "foobar"))) (Lit (Int 1)))
> (List [Lit (Int 1), Lit (Int 2)]))
.
Groom works only on Show instances that output valid
Haskell code; if Groom can't understand its input,
it will not make any changes.
