<<.from-version "5.1.23">> The <<.olink slugify>> can be used to transform arbitrary tiddler titles into human readable strings suitable for use in URLs or filenames. However, itis possible for multiple different titles to slugify to the same string. The <<.olink duplicateslugs>> operator can be used to display a warning. For example:
|
|
|
|
<$macrocall $name='wikitext-example-without-html'
|
|
src='<$list filter="[!is[system]duplicateslugs[]limit[1]]" emptyMessage="There are no duplicate slugs">
|
|
The following tiddlers have duplicate slugs:
|
|
|
|
<ul>
|
|
<$list filter="[!is[system]duplicateslugs[]]">
|
|
<li><$link><$text text=<<currentTiddler>>/></$link></li>
|
|
</$list>
|
|
</ul>
|
|
</$list>'/>
