groom: Pretty printing for well-behaved Show instances.
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.
