Language.GroteTrap.Unparse

The Unparse type class and its ParseTree instance, as well as some text manipulation.

Class Unparse

class Unparse p where

Types that are unparsable. Unparsing is like prettyprinting, except that instead of pretty source the original source code is retrieved. This means unparsing is only possible for values that were the result of an earlier parse.

Methods

unparse :: p -> String

Instances

Unparse ParseTree

Text utility functions

merge :: [String] -> String

Merge folds many strings over each other.

over :: String -> String -> String

over over' under places over' over under. The resulting string has the same characters as over' does, except where over' contains spaces; at those positions, the character from under shows. If under is longer than over', over' is padded with enough spaces to show all rest of under.
