Data.Char.Block

Contents

Datastructures to store the state of the frame.
A unicode character that is (partially) filled block.

Description

Unicode has 2-by-2 blocks, this module aims to make it more convenient to render such blocks.

Synopsis

data Row a = Row {
- left :: a
- right :: a
}
data Block a = Block {
- upper :: Row a
- lower :: Row a
}
filled :: Block Bool -> Char

Datastructures to store the state of the frame.

data Row a Source #

A data type that determines the state of the row in a block. it determines the left and the right part of the row of the block.

Constructors

Row
Fields left :: a The left part of a row of the block. right :: a The right part of the row of the block.
