Description

This module provides a pretty printer for the parse tree (`AST`).

Synopsis

- class Pretty p where
  - pretty :: p -> Doc

# Pretty Printing

class Pretty p where

A class of types which can be pretty printed

Methods

pretty :: p -> Doc

pretty print the given value

prettyPrec :: Int -> p -> Doc

`prettyPrec prec p` pretty prints p assuming that the surrounding context has a precedence of `prec`

# Testing

prettyUsingInclude :: CTranslUnit -> Doc

Pretty print the given tranlation unit, but replace declarations from header files with `#include` directives.

The resulting file may not compile (because of missing `#define` directives and similar things), but is very usefull for testing, as otherwise the pretty printed file will be cluttered with declarations from system headers.
