pprint -package:pretty-simple

Pretty print a generic value to stdout. This is particularly useful in the GHCi interactive environment.

Pretty print a showable value. An easier alias for pretty-simple's pPrint. This will print in colour if useColorOnStderrUnsafe is true.

The pprint function outputs a value of any type that is an instance of Pretty to the standard output device by calling ppr and adding a newline.

Top-level pretty printer

Pretty print a value to the standard output.

Implement either pprintTidy or pprintPrec

Pretty printing of values. This class is similar to the Pretty class from the Prettyprinter package, but it also provides pretty printing with a given precedence level. We are able to derive instances of this class for algebraic data types. You may need the DerivingVia and DerivingStrategies extensions.

data X = ... deriving Generic deriving PPrint via (Default X)

The derived instance will pretty print the value with a format similar to the one used by ormolu.

The :print & friends commands

Pretty print something that may be converted to a list as a list. Each entry is on a separate line, which means that we don't do clever pretty printing, and so this works well for large strucutures.

Pretty-print the given message into a human-readable form.

Pretty-print the given message into human-readable form, using the given Registry to decode google.protobuf.Any values.

Monochrome version of pprint. This will never print in colour.
