# pug-walk-extract-text

A small module for extracting text (e.g. inline `script` and `style` tags) from [Pug] files (formerly called Jade)!

Used by [eslint-plugin-pug].

[Pug]: https://pugjs.org

[eslint-plugin-pug]: https://github.com/myfreeweb/eslint-plugin-pug

## Installation

Install with [npm], obviously:

```bash

npm install --save-dev pug-parser pug-lexer pug-walk-extract-text

```

[npm]: https://www.npmjs.com

## Usage

```javascript

const lexer = require('pug-lexer')

const parser = require('pug-parser')

const walkExtract = require('pug-walk-extract-text')

function shouldExtract (node) {

	return node.type === 'Tag' && (node.name === 'script' || node.name === 'style')

}

const filename = 'some-file.pug'

const text = fs.readFileSync(filename, { encoding: 'utf-8' })

const results = walkExtract(parser(lexer(text, filename), filename), text, shouldExtract)

// [

//   { text: "body { background: #efefef; color: #444; }\n  html { font-size: 105%; }",

//     indent: 6, line: 9,

//     node: { attrs: [], ..., name: 'style', type: 'Tag' } },

//   { text: "console.log({\n  scri: 'pt'\n})",

//     indent: 6, line: 15,

//     node: { attrs: [], ..., name: 'script', type: 'Tag' } },

// ]

```
