[TW5] How to limit the display of tags to only certain options

[Matabele]

Hi

A problem has arisen -- how might a filter be constructed to view only the tags present, from a reference list of options.

Take for example a 'tags' field containing the list: 

done mytag [[another tag]] task [[yet another tag]]

-- how would a filter be constructed to list only those tags contained in the reference list of options:

todo active done

-- in other words, the output in this case should be: 'done'

-- or, if the reference list were:

mytag [[another tag]] calender meeting

-- the output should be: 'mytag [[another tag]]'

In other words -- what is missing in this filter expression?

[is[current]list[!!tags]what[is]missing[here]]

Hi Matabele: have a look at tobibeer/contains.

Hi Tobias

Thanks -- seem to think on similar lines; whilst you were answering, I wrote a somewhat simpler leave[] filter, specifically for the purpose.

Play around with the demo here.

the cycle operator gave me an idea, circular stories

There could be a list of tiddlers in a field, each with content. The reader would start anywhere they like and cycle though the story.

"It's non-linear: it's circular!"

Haha! Even better; circular reasoning! Permanently win an argument by giving your opponent the TW and he be stuck in an endless loop!

@Matabele

Thank you for this and the cycle tags thing. It will come to immediate use for me!

Hi Alex

A start for your circular story 'slideshow': 

1. paste this into a tiddler:

<span class="story-button-left"><$button class="tc-btn-invisible"><$action-listops $tiddler="MySubStoryList" $field="list" $subfilter="+[!cycle{!!story}]"/>{{$:/core/images/chevron-left}}</$button></span>
<span class="story-button-right"><$button class="tc-btn-invisible"><$action-listops $tiddler="MySubStoryList" $field="list" $subfilter="+[cycle{!!story}]"/>{{$:/core/images/chevron-right}}</$button></span>

<$navigator story="MySubStoryList" history="MySubHistoryList">
<$list filter="[list[MySubStoryList]]" history="MySubHistoryList">
<div>

! <span class="story-title"><$view field="title"/></span>
<$transclude mode="block"/>
</div>
</$list>
</$navigator>

2. Enter the list of tiddlers making up the story into the !!story field of this tiddler

3. Paste this into a stylesheet:

.story-button-left {
    float: left;
    position: relative;
}
.story-button-right {
    float: right;
    position: relative;
}
.story-title {
    left:5%;
    position: relative;
}
