### `parse(tokens, options)`
|
|
|

Convert Pug tokens to an abstract syntax tree (AST).
|
|
|

`options` can contain the following properties:
|
|
|
|
- `filename` (string): The name of the Pug file; it is included in the produced AST nodes and error handling, if provided.
|
|
- `plugins` (array): An array of plugins, in the order they should be applied.
|
|
- `src` (string): The source of the Pug file; it is used in error handling if provided.
|
|
|
|
```js
|
|
var lex = require('pug-lexer');
|
|
|
|
var filename = 'my-file.pug';
|
|
var src = 'div(data-foo="bar")';
|
|
var tokens = lex(src, {filename});
|
|
|
|
var ast = parse(tokens, {filename, src});
|
|
|
|
console.log(JSON.stringify(ast, null, ' '))
|
|
```
|
|
|
|
```json
