ANSI-to has the following plugins available:

  • SVG - Export ANSI to Scalable Vector Graphics
  • PNG, JPG - Export ANSI to raster image (JPG, PNG)
  • HTML (coming soon)

The SVGs output have been tested with Chrome, Firefox and Sketch.

Install

$ yarn add ansi-to-svg

Usage

const ansiToSVG = require('ansi-to-svg')

// Returns an SVG string
ansiToSVG(ansiText, {
	// Defaults to  2x for Retina compatibility
	scale: 2,

	// Font settings
	fontFace: 'Courier',
	fontSize: 14,
	lineHeight: 18,

	// Padding
	paddingTop: 0,
	paddingLeft: 0,
	paddingBottom: 0,
	paddingRight: 0,

	// Supply an iTerm2 Color file
	colors: './base16-flat-dark-f1lt3r-256.itermcolors',

	// Or override the default colors
	// (all defaults shown here)
	colors: {
		black: '#000000',
		red: '#B22222',
		green: '#32CD32',
		yellow: '#DAA520',
		blue: '#4169E1',

## Basic Text

```js
const antoToSVG = require('ansi-to-svg')
const chalk = require('chalk')
const ansiText = chalk`Your {red $wish}\n is {bgYellow.cyan my} command.`

const result = ansiToSVG(ansiText)

Saving this result to an .SVG file and opening it in your browser would reveal:

basic-example.svg

Logging the result to console would show:

</svg>

iTerm2 Color Support

const ansiText = chalk`Your {red $wish}\n is {bgYellow.cyan my} command.`
const colorFile = 'base16-flat-dark-f1lt3r-256.itermcolors'

ansiToSVG(ansiText, {color: colorFile})

Powerline Font Compatability

const ansiText = chalk` {bgGreen.white Testing background colors } butting adjacent lines. \n` +
	chalk` {red ✘ }{bgBlue.black  ~/repos/minkjs/ansi-to }{bgYellow.blue  }{bgYellow.black  svg-image-plugins ● }{yellow } ava powerline-fonts.test.js \n` +
	chalk`  {green 1 passed}`

ansiToSVG(ansiText, {
	colors: 'base16-flat-dark-f1lt3r-256.itermcolors',
	fontFamily: 'SauceCodePro Nerd Font'
})

Note: you will need SauceCodePro Nerd font for the following example to render correctly. You can find Nerd Fonts here: https://nerdfonts.com/

We can render it with ansiToSVG:

const ansiText = fs.readFileSync('all-supported-styles.ansi')
ansiToSVG(String(ansiText), {colors: 'base16-flat-dark-f1lt3r-256.itermcolors'})

Resulting in the following output:

chalk-base-styles.svg

Note: this example uses Chalk as a base to write the ANSI Escape sequences.

Light Color Scheme

const result = ansiToSVG(String(ansiText), {colors: 'base16-tomorrow-256.itermcolors'})

Padding

const ansiText = chalk`{red.bold padding} {green.italic woo!}`
const colorFile = './fixtures/base16-flat-dark-f1lt3r-256.itermcolors'

const result = ansiToSVG(String(ansiText), {
	colors: colorFile,
	paddingTop: 14,
	paddingLeft: 14,
	paddingRight: 14,
	paddingBottom: 14
})

Combined Strikethrough and Underline

const ansiText = chalk`{bgCyan.yellow.strikethrough.underline woo!}`
const colorFile = './fixtures/base16-flat-dark-f1lt3r-256.itermcolors'

const result = ansiToSVG(String(ansiText), {

	paddingBottom: -2.5,
	paddingRight: 1
