help on filter and enlist

[Laurent Bonet]

Hello,

Would like to get help on how to write a filter which include enlist.

I want to filter a list which is contained in field called validity (see attached screenshot).

with filter="[enlist{!!validity}title[B]" everything is fine I'm getting a B value.

with filter="[enlist{!!validity}title[X]]" I was hoping to get nothing as X is not part of "A B C" but I'm getting the X value...

Thanks in advance for your help.

The problem is that title in your filter is a construction operator (https://tiddlywiki.com/#Selection%20Constructors)

If the things listed are tiddlers than you can use field:title[X] and it will work the way you expect, but only if there is a tiddler called X.

If the list isn't just titles of tiddlers that exist than to do what you want to do you can use prefix or suffix like this:

<$list filter='[enlist{!!validity}prefix[X]]'>

</$list>

Of course this isn't perfect because it will match anything that has the title as a prefix. You can combine prefix and suffix to be a bit safer but it is also not prefect

[enlist{!!validity}prefix[X]suffix[X]]

Perfect. Thanks so much for the reactivity and the clarity of the answer!
