Now we respond dynamically to changes in the location hash in the URL bar. It means that you can do links in HTML as `<a href=“#HelloThere”>go</a>` and in Markdown as `[example link](#HelloThere).` We still need to make startup.js more modular

Permalinks allow direct links to individual tiddlers within a TiddlyWiki.
|
|
|
|
! Simple Permalinks
|
|
|
|
The simplest form of permalink is a single target tiddler title appended to the base URL with `#`:
|
|
|
|
http://tiddlywiki.com/#HelloThere
|
|
|
|
The tiddler title can contain spaces if required:
|
|
|
|
[[http://tiddlywiki.com/#Using TiddlyWiki on Node.js]]
|
|
|
|
Note that double square brackets are not required around the target tiddler title; however, if present they are silently removed.
|
|
|
|
! Story Permalinks
|
|
|
|
The permalink can also specify the story list of tiddlers that should be opened alongside the target tiddler as a [[TiddlerFilter|TiddlerFilters]]:
|
|
|
|
[[http://tiddlywiki.com/#TiddlerFields:Tiddlers TiddlerTags TiddlerFields ContentType]]
|
|
|
|
If the target tiddler isn't present in the story list then it is automatically inserted at the top. This means that the following two examples both target the tiddler `Tiddlers` within the story sequence `Tiddlers`, `Tags`, `TiddlerFields`:
|
|
|
|
[[http://tiddlywiki.com/#Tiddlers:Tags TiddlerFields]]
|
|
|
|
[[http://tiddlywiki.com/#Tiddlers:Tiddlers Tags TiddlerFields]]
|
|
|
|
It is also possible to specify a story filter without specifying a target tiddler for navigation:
|
|
|
|
<a href="http://tiddlywiki.com/#:[tags[task]]">~http://tiddlywiki.com/#:[tags[task]]</a>
|

! About URL encoding
|
|
|
|
There are technical restrictions on the legal characters in an URL fragment. To allow all tiddler titles to be addressed, illegal characters are subject to a process called "URL encoding" whereby problematic characters are replaced by their numeric code. For example, the space character is replaced with `%20`.
|
|
|
|
Both the target tiddler title and the story filter should be URL encoded (but not the separating colon). TiddlyWiki generates properly encoded URLs which can look quite ugly. However, in practice browsers will usually perfectly happily process arbitrary characters in URL fragments. Thus when creating permalinks manually you can choose to ignore URL encoding.
