title: LinkWidget
tags: widget

The `link` widget generates links to tiddlers.

! Content and Attributes

|!Attribute |!Description |
|to |The title of the target tiddler for the link (defaults to the [[WidgetVariable: currentTiddler]]) |

The content of the link widget is rendered within the `<a>` tag.

! CSS Classes

* `tw-tiddlylink` - applied to all links
* `tw-tiddlylink-external` - applied to external, non-tiddler links
* `tw-tiddlylink-internal` - applied to tiddler links
* `tw-tiddlylink-missing` - applied to tiddler links where the target tiddler doesn't exist
* `tw-tiddlylink-resolves` - applied to tiddler links when the target tiddler does exist

! Configuration macros

Configuration macros can be used to modify the behaviour of the link widget.

!! tw-wikilinks

Links are suppressed if the macro `tw-wikilinks` evaluates to the string `no`. For example:

```
\define tw-wikilinks() no
```

!! tw-wikilink-template

Link targets default to the URL encoded title of the tiddler. The `href` can be templated by defining the configuration macro `tw-wikilink-template`, and including within it the token `$uri_encoded$`. For example:

```
\define tw-wikilink-template() http://tiddlywiki.com/#$uri_encoded$
```

Note that in the browser the `<a>` element generated by the link widget has a JavaScript event handler that navigates directly to the target tiddler, ignoring the `href` attribute.
