@ -9,4 +9,34 @@ Freelinking is activated for runs of text that have the following variables set:
* `tv-wikilinks` is NOT equal to `no`
* `tv-freelinks` is set to `yes`
Freelinks are case sensitive.
Within view templates, the variable `tv-freelinks` is automatically set to the content of $:/config/Freelinks/Enable, which can be set via the settings panel of this plugin.
!! Notes
To change within which tiddlers freelinking occurs requires customising the shadow tiddler $:/plugins/tiddlywiki/freelinks/macros/view. This tiddler is tagged $:/tags/Macro/View which means that it will be included as a local macro in each view template. By default, its content is:
```
<$set name="tv-freelinks" value={{$:/config/Freelinks/Enable}}/>
```
That means that for each tiddler the variable tv-freelinks will be set to the tiddler $:/config/Freelinks/Enable, which is set to "yes" or "no" by the settings in control panel.
Instead, we can use a filter expression to, say, only freelink within the tiddler with the title "HelloThere":
```
<$set name="tv-freelinks" value={{{ [<currentTiddler>match[HelloThere]then[yes]else[no]] }}}/>
```
Or, we can make a filter that will only freelink within tiddlers with the tag "MyTag":
```
<$set name="tv-freelinks" value={{{ [<currentTiddler>tag[MyTags]then[yes]else[no]] }}}/>
```
Or we can combine both approaches:
```
<$set name="tv-freelinks" value={{{ [<currentTiddler>match[HelloThere]] ~[<currentTiddler>tag[MyTag]] +[then[yes]else[no]] }}}/>
```
