Printer combinators for printing values of types implementing Outputable.

Documentation

output :: (HasCallStack, Outputable a) => a -> Printer ()

Prints the given value using the type's Outputable implementation.

The use of this function should be avoided for these reasons:

• It may raise an error due to showPpr returning a String containing ns. Use newline to print ns.
• ghc-lib-parser may change a type's implementation of Outputable, causing a sudden test failure. It becomes a maintaince burden.
• All comments of the node's children are ignored.

showOutputable :: Outputable a => a -> String

Converts the given value to a String.
