SID-00945: Formatted Search, changes to two version back

Status: Answered Answered TWiki version: 4.2.4 Perl version:
Category: CategorySearch Server OS: Last update: 13 years ago

According to the docs for Formatted Search, $changes(n) will give me changes between the latest version and version n.

However, in a search, I really can't guess what n should be. I'm more likely to want to see changes between the latest and two back, or three back, than some explict n.

I tried

%SEARCH{".*"  type="regex" nosearch="on" noheader="on" 
   newline="%BR%" order="modified" limit="20" reverse="on" 
   format="| [[$web.$topic][$topic]] | r $rev | $date -- $wikiname | $changes | $changes($percntCALC{$EVAL($rev - 1)}$percnt) | "}%

But

$changes($percntCALC{$EVAL($rev - 1)}$percnt)

isn't giving me what I want.

I assume there's an "order of evaluation" problem.

Can I do what I want to do? If so, how?

Discussion and Answer

The doc is correct, I just checked the code. Whoever designed this spec did not think about usability. Yes, relative version number would be more usable.

CALC will not work here because you need the result of the calculated version number for each search hit, but before $changes is evaluated, which is not possible.

I recommend to post a feature request. Possible spec to remain compatible: Use a negative number to indicate relative version number compared to the current top version. For example, a $changes(-2) shows the difference between the two most recent revisions.
