> Snapdragon utility for creating a new AST node in custom code, such as plugins.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save snapdragon-node
```
## Usage
With [snapdragon](https://github.com/jonschlinkert/snapdragon) v0.9.0 and higher you can use `this.node()` to create a new `Node`, whenever it makes sense.
```js
var Node = require('snapdragon-node');
var Snapdragon = require('snapdragon');
var snapdragon = new Snapdragon();
// example usage inside a parser visitor function
snapdragon.parser.set('foo', function() {
// get the current "start" position
var pos = this.position();
// returns the match if regex matches the substring
// at the current position on `parser.input`
var match = this.match(/foo/);
if (match) {
// call "pos" on the node, to set the start and end
// positions, and return the node to push it onto the AST
// (snapdragon will push the node onto the correct
// nodes array, based on the stack)
return pos(new Node({type: 'bar', val: match[0]}));
}
});
```
## API
### [Node](index.js#L22)
Create a new AST `Node` with the given `val` and `type`.
**Params**
* `val` **{String|Object}**: Pass a matched substring, or an object to merge onto the node.
* `type` **{String}**: The node type to use when `val` is a string.
* `returns` **{Object}**: node instance
**Example**
```js
var node = new Node('*', 'Star');
var node = new Node({type: 'star', val: '*'});
```
