Help with simple filter using compare operator

#1

Hello

I am trying to understand how to construct a filter to select tiddlers based on the values in two fields.

<$list filter="[tag[tag1]get{!!field1}compare:number:eq{!!field2}]" variable=result1>

<<result1>>

There is at least one tiddler which is tagged tag1 and where field1 and field2 have the same value, but my filter does not find that tiddler.

What have I done incorrectly?

Cheers, Rob

Try using a :filter[...] filter run prefix

<$list filter="[tag[tag1]] :filter[{!!field1}compare:number:eq{!!field2}]" variable=result1>

<<result1>>
</$list>

Notes:

  • The first filter run ([tag[tag1]]) get a list of tiddler titles
  • The second filter run (:filter[...]) processes each title from the first filter run, and only retains titles that satisfy the comparison. Note that, within the :filter[...] filter run, the “currentTiddler” is set to each title in turn. This allows you to use {!!field1} and {!!field2} references.

enjoy,
