A question of sort: Sort tiddlers by some calculated values

[Mohammad Rahmani]

Assume you have filtered a list of tiddlers.

1. For example you list all tiddlers tagged by student
2. Each tiddler has two fields:  chemistry and math
3. I want sort these tiddler by average value calculates as a = 0.5*(math+chemistry)

I am looking for one $list or one step listing!

Sidenote: I know I can calculate average and prefix to tiddler name (a-name) and then sort and display by removing prefixes.

Best wishes

Use the sortsub operator, or in 5.1.24 the :sort run prefix

Thank you Saq!

I will!

Best wishes

That is amazing Saq!

This is my solution and it works! This way we can write shorter and more clear codes!

<$vars vv-avgSubfilter="[{!!chemistry}] [{!!math}] +[average[]]">
  <$list filter="[tag[student]sortsub:number<vv-avgSubfilter>]">
    <$link/> - <$text text={{{[subfilter<vv-avgSubfilter>]}}} /><br>
  </$list>
</$vars>

Saq,

 I think it worth adding some more examples to official documentation!

@Mohammad you know what I am going to say next ;)

[Mohammad Rahmani]

Got it;-)

Best wishes
