ASTPrettyPrinter
Description
Type class for pretty printing ASTs.
Synopsis
- class Show g => ASTPrettyPrinter g where
- prettyPrint :: Monoid b => b -> (Node g a -> Int -> b) -> (Node g a -> String -> b) -> (Node g a -> b) -> AST g a -> b
- showCode :: (Show a, Grammar g, ASTPrettyPrinter g) => AST g a -> String
- showCodeAs :: (Monoid b, ASTPrettyPrinter g) => b -> (Node g a -> Int -> b) -> (Node g a -> String -> b) -> (Node g a -> b) -> AST g a -> b
Documentation
class Show g => ASTPrettyPrinter g where Source #
An ASTPrettyPrinter can pretty print ASTs of a certain grammar.
Methods
prettyPrint :: Monoid b => b -> (Node g a -> Int -> b) -> (Node g a -> String -> b) -> (Node g a -> b) -> AST g a -> b Source #
Pretty prints the given AST (last argument) to another type b (e.g., String).
Parameters are:
* the start indent (e.g., ""),
* an indent generator that can generate an indent of a certain width within the context of printing a certain node (e.g., (_ i -> genIndent i)),
* a function to lift strings to the output type b within the context of printing a certain node,
* a function print nodes, and
* the AST to print.
