This macro can return the name of tiddler and a true/false if it has / has
not text
\define hasText(tid)
<$set name="Tiddler" value=<<__tid__>> >
<$reveal type="match" default=<<Tiddler>> text={{{ [<Tiddler>has[text]] }}}>
<<Tiddler>>: True
</$reveal>
<$reveal type="nomatch" default=<<Tiddler>> text={{{ [<Tiddler>has[text]]
}}}>
<<Tiddler>>: False
</$reveal>
</$set>
\end
- Test
In https://tiddlywiki.com/ create two tiddlers one Test01 and the other
Test02, put a text in the first tiddler and leave empty the second, then
try as below
<<hasText Test01>>
<<hasText Test02>>
The results will be
Test01: False
Test02: True
If you like to use it inside a list widget, tag above two tiddlers with
something e.g test
<$list filter="[tag[test]]">
<$macrocall $name="hasText" tid=<<currentTiddler>> /><br>
</$list>
You will have then:
Test01: False
Test02: True
Good luck
