module Data.Text.Zipper
text-zipper
This module provides a two-dimensional text zipper data structure. This structure represents a body of text and an editing cursor which can be moved throughout the text, along with a set of editing transformations. Text zippers are generalized over the set of data types that might be used to store lists of characters (e.g., String, Text, etc.). As a result, the most general way to create a text zipper is to use mkZipper and provide all of the functions required to manipulate the underlying text data. Implementations using Text and String are provided.
data TextZipper a
text-zipper Data.Text.Zipper
clearZipper :: Monoid a => TextZipper a -> TextZipper a
text-zipper Data.Text.Zipper
Empty a zipper.
mkZipper :: Monoid a => (Char -> a) -> (Int -> a -> a) -> (Int -> a -> a) -> (a -> Int) -> (a -> Char) -> (a -> a) -> (a -> Bool) -> (a -> [a]) -> (a -> [Char]) -> [a] -> Maybe Int -> TextZipper a
text-zipper Data.Text.Zipper
Create a zipper using a custom text storage type. Takes the initial text as well as all of the functions necessary to manipulate the underlying text values.
stringZipper :: [String] -> Maybe Int -> TextZipper String
text-zipper Data.Text.Zipper
Construct a zipper from list values.
textZipper :: [Text] -> Maybe Int -> TextZipper Text
text-zipper Data.Text.Zipper
Construct a zipper from Text values.
vectorZipper :: [Vector Char] -> Maybe Int -> TextZipper (Vector Char)
text-zipper Data.Text.Zipper
Construct a zipper from vectors of characters.
