Item9464: Improve capabilities of SEARCH $changes parameter

In Formatted Search

$changes(n)      Summary of changes between latest rev and rev n 

That's not as helpful as it might be. I rarely know what n should be. I'm more likely to want to see changes between latest and 2 back, or 3 back...

I'd like to see support added for this, perhaps

$changes(n)      Summary of changes between latest rev and rev n; 
                 if n is a negative number, show summary of changes between latest
                 rev and "n" revisions ago.

So if I say $changes(-2) and latest is rev 19, show changes between 19 and 17; if latest is 5, changes between 5 and 3, and so on.

That would let me do this:

%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(-2) | "}%

Excellent point. It seems like a trivial enhancement, but it probably needs a feature proposal.

Set as enhancement

For what it's worth, this horrible monster could be a work-around:

%STARTSECTION{"search"}%
%SEARCH{"1"
   type="query"
   nonoise="on"
   newline="%BR%"
   order="modified"
   limit="20"
   reverse="on" 
   format="| [[$web.$topic][$topic]] | r $rev | $date -- $wikiname | $changes | Since rev($percntINCLUDE{      \"%TOPIC%\"      section=\"rev\"      web=\"$web\"      topic=\"$topic\"      n=\"-2\"   }$percnt): $changes($percntINCLUDE{      \"%TOPIC%\"      section=\"rev\"      web=\"$web\"      topic=\"$topic\"      n=\"-2\"   }$percnt) | Since rev(5): $changes(5) |"}%
%ENDSECTION{"search"}%

%STARTSECTION{"rev"}%%CALC{"$SUM(%REVINFO{
   "$rev"
   web="%web%"
   topic="%topic%"
}% , %n%)"}%%ENDSECTION{"rev"}%

I'm not sure that "horrible monster" is doing what you think. The results are similar to what I got using CALC. No + or - anywhere in the output is suspicious. I don't think it's actually a diff.

-- VickiBrown - 13 Aug 2010

I don't quite agree - the $percentINCLUDE is correctly calculating the rev number -2 - however I would agree that the $changes() token isn't very useful in its output; probably, that's a bug

-- PaulHarvey - 14 Aug 2010

Okay, now it should be fixed (the example, that is)

-- PaulHarvey - 17 Aug 2010

I've raised Item9502 for the crash this example causes on 1.1 - separate from the issues that Vicki raises.
