node-drawille

Drawing in terminal with unicode braille characters. The idea is based on drawille by @asciimoo.

Install

$ npm install drawille

Usage

See examples.

This module provides a very basic API only, for fancy things, like drawing lines, use another module, like bresenham.

drawille-canvas provides HTML5 Canvas API for drawille (WIP).

API

Canvas(w, h)

Create a new canvas with the given dimensions. w must be multiple of 2, h must be multiple of 4.

canvas.set(x, y)

Draw point on canvas at the given position.

canvas.unset(x, y)

Delete point on canvas at the given position.

canvas.toggle(x, y)

Toggle point on canvas at the given position.

canvas.clear()

Clear the whole canvas (delete every point).

canvas.frame()

Return the current content of canvas, as a newline-delimited string. It uses braille characters to represent points, so every line has length of w/2, and the string contains h/4 lines.
