+# delta-detect-links
+
+> Detect links in a delta object.
+
+This small library is based on [`linkify-it`](https://github.com/markdown-it/linkify-it) to detect links in a rich text [`Delta`](https://github.com/ottypes/rich-text) object.
+The main purpose for this library is to automatically detect links in [Quill](http://quilljs.com/) documents.
+
+## API
+
+### `detectLinks`
+
+This function detects all links in the given `insert`-only delta object.
+
+```js
+const detectLinks = require('delta-detect-links');
+
+detectLinks((new Delta()).insert('Visit www.example.com\n'));
+// → [ { insert: 'Visit ' }, { insert: 'www.example.com', attributes: { link: 'http://www.example.com' } }, { insert: '\n' } ]
+```
+
+Already existing links in the given delta object will be skipped and not highlighted a second time.
+
+#### Options
+
+`detectLinks` supports an optional second parameter to set the following options:
+
+* `skipTrailingMatch` (default: `false`): This is useful when you want to detect links in real-time while the user types. In order to prevent detection of partial links the link will only be detected after another stop word has been encountered.
+* `lastIndex`: This option is only used in combination with `skipTrailingMatch`. This value is used to determine the trailing match. It is useful in scenarios where the current cursor is not at the same position as the end of the document.
+
+### `detectLinksDelta`
+
+Similar to `detectLinks` but only contains the changes delta object.
+
+```js
+const detectLinksDelta = require('delta-detect-links').detectLinksDelta;
+
+detectLinksDelta((new Delta()).insert('Visit www.example.com\n'));
+// → [ { retain: 6 }, { retain: 15, attributes: { link: 'http://www.example.com' } } ]
+```
