pt :: Int -> Int -> Point

Make Point from line and column

start :: Point

Point at the beginning

lineStart :: Int -> Point

Point at the beginning of line

regionLength :: Lens' Region Size

Regions length

till :: Point -> Point -> Region

Region from one Point to another

linesSize :: Int -> Size

Distance of n lines

regionLines :: Lens' Region Int

emptyRegion :: Region -> Bool

Is Region empty

line :: Int -> Region

n'th line region, starts at the beginning of line and ends on the next line

regionSize :: Point -> Size -> Region

Make Region by start position and Size

expandLines :: Region -> Region

Expand Region to contain full lines

atRegion :: Editable s => Region -> Lens' (Contents s) (Contents s)

Get contents at Region

overlaps :: Region -> Region -> Bool

Does regions overlaps

applyMap :: Map -> Region -> Region

cutMap :: Region -> Map

Cut Region mapping

insertMap :: Region -> Map

Opposite to cutMap

cutRegion :: Region -> Region -> Region

Update second Region position as if it was data cutted at first Region

insertRegion :: Region -> Region -> Region

Update second region position as if it was data inserted at first region (region sets insertion point and data size) Region tries not to extend if data inserted at region bound except when region is empty This allows define replace as cut and insert in special case when we replace region itself

class Editable s => EditAction e s where

Minimal complete definition

replace, actionMap, perform, inversed

Methods

replace :: Region -> Contents s -> e s

Make replace action over Region and Contents

actionMap :: e s -> Map

inversed :: e s -> Contents s -> e s

Get action undo
