TW5 - Way to change formatting of a link to a tiddler based on a tag that tiddler has?

[Matthew Petty]

I have lots of tiddlers tagged with "task" and "done". I use the cool checkbox feature to check off tasks as done.

If a tiddler doesn't exist, it is written in italics. Therefore, it's possible to format the link based on an attribute of that tiddler.

So, is it possible to format a link to an existing tiddler tagged with "done" with strikethrough (or other formatting)?

For example:

This tiddler does not exist

This tiddler does exist and is NOT tagged "done"

---This tiddler does exist and IS tagged "done"--- (struck through)

Can this be done?

[Stephan Hradek]

Almost possible.

Create a tiddler called (e.g.) "tasklink" with this content (as an example)

<$list filter="[is[current]tag[done]]">
<strike>
<$link><$view field="title"/></$link>
</strike>
</$list>
<$list filter="[is[current]tag[task]!tag[done]]">
<span style="background-color:pink">
<$link><$view field="title"/></$link>
</span>
</$list>

Then, instead of writing [[mytask]], write {{mytask||tasklink}}

Hope this helps.

That's very useful, thank you!

How do you use task that doesn't exist as a tiddler?

That's great, thank you!
