playing around with a copy of TagTemplate, and trying to get a tag pill to display a count of the number of tiddlers with said tag

[Elijah]

There is a little bit in TagTemplate: tag=<<currentTiddler>>, which tells the tag-pill what to display. With the default <<currentTiddler>>, it will display the title of the tiddler corresponding to the tag. With {{!!caption}} it'll display the contents of the caption-field of the tag-tiddler.

Now, I'm trying to figure out how to get the tag-pill to instead display the number of tiddlers tagged with some specific tag. I thought {{{[tag[<<currentTiddler>>]count[]]}}} would work, but it doesn't - it simply displays "0". However, if you manually-input the title of the tag in the same filter as follows: {{{[tag[ACTUALTAG]count[]]}}}, it displays the correct count. I admit I don't understand how the filter-operators work, or even how to correctly call them (the documentation (specifically Filter Operators, count Operator, and count Operator (Examples)) was unhelpful to me), and I got the {{{[tag[ACTUALTAG]count[]]}}} from Tobias Beer's tiddlywiki. Any help would be appreciated. Thanks.

When using variables as a filter parameter, the syntax is different from what you are attempting. Try {{{[tag<currentTiddler>count[]]}}}

See https://tiddlywiki.com/#Filter%20Parameter and the bottom of https://tiddlywiki.com/#Introduction%20to%20filter%20notation for the documentation related to this.

That's it. Thanks.

I don't know if you'll find this helpful, but I use a small macro - that I use to put in the caption field of Table of Content Tiddlers, and also use above lists based on a tag.

Tiddler name (example): $:/_macro/count-tag
Tiddler must be tagged: $:/tags/Macro

\define count-tag(tag-name)
<$count filter="[tag[$tag-name$]]"></$count>
\end

The macro <<count-tag MyTagName>> ` is useful in places such as:

• A summary above a list based on a single tag, Example:
• This list contains <<count-tag MyTagName>> tiddlers tagged with <<tag MyTagName>>
• The caption field of a Table of Contents tiddler, where it can be used to display the number of tiddlers that will be found under that link. Example, the caption field contains:
• My Tag Name ^^(<<count-tag MyTagName>>)^^

Of course it can also be used within a tiddler whose title is the tag in this way:  <$macrocall $name="count-tag" tag-name={{!!title}}/> :but then it is simpler to just use the $count widget: <$count filter="[tag<currentTiddler>]"/>
