[Changelog](Changelog.md)

ANSI-to-SVG provides a Markdown friendly way to include Node.js CLI output in your software documentation; like this SVG here:

[![hello-world.svg](https://f1lt3r.github.io/ansi-to-svg/examples/hello-world.svg)](https://raw.githubusercontent.com/F1LT3R/ansi-to-svg/master/examples/hello-world.svg)

## Support

Support the development of ANSI-to-SVG by [becoming a patreon](https://patreon.com/bePatron?u=9720216).

## Features

ANSI-to-SVG sits on top of tha base-package [ANSI-to](https://github.com/F1LT3R/ansi-to) and is part of a collection of tools used for ZDD development.

ANSI-to has the following plugins available:

- [SVG](https://github.com/F1LT3R/ansi-to-svg.git) - Export ANSI to Scalable Vector Graphics
- [PNG, JPG](https://github.com/F1LT3R/ansi-to-image) - Export ANSI to raster image (JPG, PNG)
- [<strike>HTML</strike>](https://github.com/F1LT3R/ansi-to-html) (coming soon)

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

## Install

```
$ yarn add ansi-to-svg
```

## Usage

```js
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',
		magenta: '#9932CC',
		cyan: '#008B8B',
		white: '#D3D3D3',
		gray: '#A9A9A9',
		redBright: '#FF4500',
		greenBright: '#ADFF2F',
		yellowBright: '#FFFF00',
		blueBright: '#87CEEB',
		magentaBright: '#FF00FF',
		cyanBright: '#00FFFF',
		whiteBright: '#FFFFFF',
		bgBlack: '#000000',
		bgRed: '#B22222',
		bgGreen: '#32CD32',
		bgYellow: '#DAA520',
		bgBlue: '#4169E1',
		bgMagenta: '#9932CC',
		bgCyan: '#008B8B',
		bgWhite: '#D3D3D3',
		bgGray: '#A9A9A9',
		bgRedBright: '#FF0000',
		bgGreenBright: '#ADFF2F',
		bgYellowBright: '#FFFF00',
		bgBlueBright: '#87CEEB',
		bgMagentaBright: '#FF00FF',
		bgCyanBright: '#00FFFF',
		bgWhiteBright: '#FFFFFF',
		backgroundColor: '#000000',
		foregroundColor: '#D3D3D3'
	}
})
```

})
```

## 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](https://f1lt3r.github.io/ansi-to-svg/examples/basic-example.svg)](https://raw.githubusercontent.com/F1LT3R/ansi-to-svg/master/examples/basic-example.svg)

Logging the result to console would show:

```xml
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0, 0, 126.02, 40.45" font-family="SauceCodePro Nerd Font, Source Code Pro, Courier" font-size="14"><g fill="#D3D3D3"><rect x="0" y="0" width="126.02" height="40"><svg xmlns="http://www.w3.org/2000/svg" viewBox="0, 0, 126.02, 40.45" font-family="SauceCodePro Nerd Font, Source Code Pro, Courier" font-size="14">
	<g fill="#D3D3D3">

		<text x="0" y="14.55">Your </text>
		<text x="42.01" y="14.55" fill="#B22222">$wish</text>

		<text x="58.81" y="33.55"> command.</text>
	</g>
</svg>
```

## iTerm2 Color Support

Using: [./fixtures/base16-flat-dark-f1lt3r-256.itermcolors](./fxitures/base16-flat-dark-f1lt3r-256.itermcolors)

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

ansiToSVG(ansiText, {color: colorFile})
```

[![iterm2colors-file.svg](https://f1lt3r.github.io/ansi-to-svg/examples/iterm2colors-file.svg)](https://raw.githubusercontent.com/F1LT3R/ansi-to-svg/master/examples/iterm2colors-file.svg)

## Emoji Support

```js
const ansiText = chalk.bgRed('🌈') +
	chalk.bgYellow('🦄') +
	chalk.bgGreen('🐘') +
	chalk.bgCyan('🍄') +
	chalk.bgBlue('🎃') +
	chalk.bgMagenta('🐦') +
	chalk.bgRed('🖤') +
	chalk.bgYellow('😳') +
	chalk.bgGreen('😒') +
	chalk.bgCyan('😮') +
	chalk.bgBlue('😐') +
	chalk.bgMagenta('😱') +
	chalk.bgRed('😕') +
	chalk.bgYellow('😕') +
	chalk.bgGreen('😑') +
	chalk.bgCyan('😘')

ansiToSVG(ansiText, {
	colors: 'base16-flat-dark-f1lt3r-256.itermcolors'
})
```

[![emojis.svg](https://f1lt3r.github.io/ansi-to-svg/examples/emojis.svg)](https://raw.githubusercontent.com/F1LT3R/ansi-to-svg/master/examples/emojis.svg)

## Powerline Font Compatability

```js
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/](https://nerdfonts.com/)

## All Styles

If we dump some ANSI to a file: [fixture.chalk-styles.ansi](fixtures/fixture.chalk-styles.ansi)

```plaintext

```

We can render it with `ansiToSVG`:

```js
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](https://f1lt3r.github.io/ansi-to-svg/examples/chalk-base-styles.svg)](https://raw.githubusercontent.com/F1LT3R/ansi-to-svg/master/examples/chalk-base-styles.svg)

Note: this example uses [Chalk](https://github.com/chalk/chalk) as a base to write the ANSI Escape sequences.

## Light Color Scheme

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

[![light-iterm2-color-scheme.svg](https://f1lt3r.github.io/ansi-to-svg/examples/light-iterm2-color-scheme.svg)](https://raw.githubusercontent.com/F1LT3R/ansi-to-svg/master/examples/light-iterm2-color-scheme.svg)

## Padding

```js
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

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

const result = ansiToSVG(String(ansiText), {
	colors: colorFile,
	paddingTop: 1,
	paddingLeft: 1,
	paddingBottom: -2.5,
	paddingRight: 1
})
```
