[tw] Re: List of tiddler conditioned by links in fields

[FND]

 I want to write a list of all the tiddlers tiddlerFive own a part of

So essentially, you want a list of tiddlers where either field A or B 
contain a particular term?
The ForEachTiddler plugin should do the job - pseudo code:
 forEachTiddler
 where tiddler.fields.owneralpha.contains(tiddlerFive) ||
 tiddler.fields.ownerbeta.contains(tiddlerFive)
 print * [[ + tiddler.title + ]]

HTH.

 I want to write a list of all the tiddlers
 tiddlerFive own a part of (ei tiddlers that link to tidderFive FROM
 either field owneralpha or ownerbeta (=tiddlerOne and tiddlerTwo)).

Without using any plugins at all, you can create a tiddler (e.g.,
[[ShowList]]), containing:

/%
!out
$1
!end
%/tiddler ShowList##out with: {{
var out=[];
var target=$1;
var tids=store.getTiddlers();
for (var i=0;itids.length;i++) {
   var alpha=tids[i].fields.owneralpha;
   var beta=tids[i].fields.ownerbeta;
   if (alpha  alpha.contains(target)
  || beta  beta.contains(target))
 out.push(*[[+tids[i].title+]]);
}
out.join(\n);}}

Then, embed the following in some other tiddler:
   tiddler ShowList with: TiddlerName
e.g.
   tiddler ShowList with: tiddlerFive

Note: to get a list for the *current* tiddler, you can pass it's
title, like this:
   tiddler ShowList with: {{tiddler.title}}

enjoy,

 /%
 !out
 $1
 !end
 %/tiddler ShowList##out with: {{
 var out=[];
 var target=$1;
 var tids=store.getTiddlers();
 for (var i=0;itids.length;i++) {
    var alpha=tids[i].fields.owneralpha;
    var beta=tids[i].fields.ownerbeta;
    if (alpha  alpha.contains(target)
       || beta  beta.contains(target))
          out.push(*[[+tids[i].title+]]);}

This works perfectly thank you very much.

A new problem, however, arises out of this solution.

Let's say I create an additional two custom fields owneralphapercent
and ownerbetapercent. And create two tiddlers, percentLinkAlpha and
percentLinkBeta in which I put

 /%
!out
[[$1|$2]]
!end
%/tiddler percentLinkAlpha##out with:
   {{store.getValue('$1','owneralphapercent')}} [[$1]]

Futhermore I change the above code to

/%
!out
$1
!end
%/tiddler ShowList##out with: {{
var out=[];
var target=$1;
var tids=store.getTiddlers();
for (var i=0;itids.length;i++) {
   var alpha=tids[i].fields.owner3;
   var beta=tids[i].fields.owner6;
   if (alpha  alpha.contains(target))
 out.push(This tiddler own: tiddler percentLinkAlpha with:
[[+tids[i].title+]]  of [[+tids[i].title+]]);
  if (beta  beta.contains(target))
  out.push(This tiddler own: tiddler percentLinkBeta with:
[[+tids[i].title+]]   of [[+tids[i].title+]]);
}

out.join(\n);}}

Can this be made to work? How do stop the right chevrons () I've
added from executing the code prematurely?

My goal is to have
tiddler ShowList with: tiddlerFive  write something like, 'This
tiddler own: 75% of tiddlerOne'
 
'This tiddler own: 66,66% of tiddlerTwo'

Regards

          out.push(This tiddler own: tiddler percentLinkAlpha with:
 [[+tids[i].title+]]  of [[+tids[i].title+]]);

As you've noted, the occurrence of  within the code interferes
with the overall tiddler macro processing.  Fortunately, because
the  is contained within a javascript string, you can avoid the
problem simply by putting a \ in between the two characters (e.g., 
\, like this:

out.push(This tiddler own: tiddler percentLinkAlpha with: [[+tids
[i].title+]]\  of [[+tids[i].title+]]);

Note: a similar problem arises if you attempt to use the 'close CSS
wrapper sequence (}}}) within the code, as this interferes with the
closing '}}' of the 'eval param' syntax.  The same kind of work-around
can be used in this case as well: }\}\}
