## Installation
npm install pug-lexer
## Usage
```js
var lex = require('pug-lexer');
```
### `lex(str, options)`
Convert Pug string to an array of tokens.
`options` can contain the following properties:
- `filename` (string): The name of the Pug file; it is used in error handling if provided.
- `plugins` (array): An array of plugins, in the order they should be applied.
```js
console.log(JSON.stringify(lex('div(data-foo="bar")', {filename: 'my-file.pug'}), null, ' '))
```
```json
[
{
"type": "tag",
"line": 1,
"val": "div",
"selfClosing": false
},
{
"type": "attrs",
"line": 1,
"attrs": [
{
"name": "data-foo",
"val": "\"bar\"",
"escaped": true
}
]
},
{
"type": "eos",
"line": 1
}
]
```
### `new lex.Lexer(str, options)`
Constructor for a Lexer class. This is not meant to be used directly unless you know what you are doing.
`options` may contain the following properties:
- `filename` (string): The name of the Pug file; it is used in error handling if provided.
- `interpolated` (boolean): if the Lexer is created as a child lexer for inline tag interpolation (e.g. `#[p Hello]`). Defaults to `false`.
- `startingLine` (integer): the real line number of the first line in the input. It is also used for inline tag interpolation. Defaults to `1`.
- `plugins` (array): An array of plugins, in the order they should be applied.
