Implements word movements for Data.Text.Zipper

moveWordLeft :: GenericTextZipper a => TextZipper a -> TextZipper a

Move one word to the left

A word is defined as a consecutive string not satisfying isSpace. This function always leaves the cursor at the beginning of a word (except at the very start of the text).

moveWordRight :: GenericTextZipper a => TextZipper a -> TextZipper a

Move one word to the right

A word is defined as a consecutive string not satisfying isSpace. This function always leaves the cursor at the end of a word (except at the very end of the text).

deletePrevWord :: (Eq a, GenericTextZipper a) => TextZipper a -> TextZipper a

Delete the previous word

Does the same as moveWordLeft but deletes characters instead of simply moving past them.

deleteWord :: GenericTextZipper a => TextZipper a -> TextZipper a

Delete the next word

Does the same as moveWordRight but deletes characters instead of simply moving past them.
