## 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.
