How to show filter variable results as normal text instead of missing link form?

1

To simplify the discussion, I’ll start with a simple example.

\define test()[is[tiddler]is[shadow]sort[title]count[]]
\define test2() {{{[is[tiddler]is[shadow]sort[title]count[]]}}}
\define test3() {{{ [is[tiddler]is[shadow]sort[title]count[]join[]] }}}
\define test4()[is[tiddler]is[shadow]sort[title]count[]join[]]

<<test>>

<$text text=<<test>> />

<<test2>>

<$text text=<<test2>> />

<<test3>>

<<test4>>

<$text text={{{[is[tiddler]is[shadow]sort[title]count[]]}}}/>

The output is shown in the image above.

Only <<test2>> got the result I wanted. But it’s a missing link form that I want to turn into plain text.

I don’t want to use that last form, that’s too much filter content to write and not good for editing and maintenance. Because I will define many similar data.

Of course I know I can use lets for definitions, in fact that’s what I’m doing at the moment. But the other problem is that I would need to use the same variable in two or more entries, which I can’t do with lets. Only define, allows me to use import to achieve this.

So can anyone tell me how I should solve this problem? Or is there no suitable solution in the current situation? Any discussion I am more than welcome and appreciated.

That last form has been the only way to get what you ask for a long time until now with the release of 5.3.x

Use a function which is a form of saved filter. Its Typicaly used in other filters and can be made into custom filter operators but used as if it was a variable it does what you ask.

\function  test4()[is[tiddler]is[shadow]sort[title]count[]join[]]

<<test4>>

\function  time()[<hour>addsuffix[:]addsuffix<minute>]

remove join[] from these filter and it works, I am not sure what you were trying to join.

Although you can also use
\function time()[<hour>] [<minute>] +[join[:]]

Glad I could help. Just letting you know there are other ways to make a time picker especialy if you want time of day.

Just note, this form only returns one results. For example

\function test() [tag[HelloThere]]

<<test>>

This will return only the first result!

A Gentle Guide to TiddlyWiki

While one expects all eight outpus (all tiddlers tagged with `HelloThere’).

Why sort is required for counting?
Why join is required when counting?

I assume, you can just write

\function  test4()    [is[tiddler]is[shadow]count[]]

and it is more performant.

  • It is not needed it was just what was in the original filter.

This answer your question

Use join so the "first value is all values;

\function test() [tag[HelloThere]join[, ]]

<<test>>
  • But remember this is to get a text only output
