Yi.Buffer.Basic

Description

Basic types useful everywhere we play with buffers.

Synopsis

data Direction = Backward | Forward reverseDir :: Direction -> Direction mayReverse :: Direction -> [a] -> [a] directionElim :: Direction -> a -> a -> a newtype Mark = Mark { markId :: Int } newtype BufferRef = BufferRef Int newtype Point = Point { fromPoint :: Int } newtype Size = Size { fromSize :: Int } fromString :: String -> Rope

Documentation

data Direction Source

Direction of movement inside a buffer Constructors Backward Forward Instances Eq Direction Ord Direction Show Direction Typeable Direction Binary Direction

reverseDir :: Direction -> Direction Source

mayReverse :: Direction -> [a] -> [a] Source

reverse if Backward

directionElim :: Direction -> a -> a -> a Source

direction is in the same style of maybe or either functions, It takes one argument per direction (backward, then forward) and a direction to select the output.

newtype Mark Source

A mark in a buffer Constructors Mark markId :: Int Instances Eq Mark Ord Mark Show Mark Typeable Mark Binary Mark

newtype BufferRef Source

Reference to a buffer. Constructors BufferRef Int Instances Eq BufferRef Num BufferRef Ord BufferRef Show BufferRef Typeable BufferRef Binary BufferRef Promptable BufferRef

newtype Point Source

A point in a buffer Constructors Point fromPoint :: Int Instances Bounded Point Enum Point Eq Point Integral Point Num Point Ord Point Real Point Show Point Ix Point Typeable Point Binary Point SemiNum Point Size

newtype Size Source

Size of a buffer region Constructors Size fromSize :: Int Instances Enum Size Eq Size Integral Size Num Size Ord Size Real Size Show Size Binary Size SemiNum Point Size

fromString :: String -> Rope Source
