Hi, I looking at your site from time to time and always finds something new 
and shine :)
This time I liked the macro from "Make data from a dictionary tiddler 
appear when you hover over something 
"
 
but I don't seem to make it work in a TW5.1.13, nothing happens, it works 
fine when I open Your site byt not when I drag the toddlers to my offline 
5.1.13?

['Stuart Amor' via TiddlyWiki]

I think I may have missed a fundamental point here. I have followed the above 
examples and entered:

\define thisSearchMacro()

<$list filter="[[$:/data/Entrance]indexes[]regexp:title[(?i)$(thisSearch)$]]">
<$transclude tiddler="$:/data/Entrance" index=<>/>


\end

<>

I don't understand how the regexp:title[(?i)$(thisSearch)$] portion of code 
works, I get the same values if it's there or not...?

Hi Jed, 

Think "logs", "comments"... all those kinds of things.

Yes and no. A tiddler may have a number of comments or logs attached to it. 
Implementing that as a number of comment-fields seems difficult and error 
prone.

That data tiddler would have to be stuffed into the system tiddler 
namespace. So, that is one option. Personally, I prefer to keep data at the 
place to which they pertain, that very tiddler. Other than not wanting to 
implement that functionality, I don't see why a tiddler itself should not 
contain complex data anywhere but its body. Whether or not they're easily 
editable within the current editors is a matter of having accessible 
editors.

What about comments for *$:/foo*, or even *$:/data/foo*? I think the 
complexity gets arbitrarily confusing. I think it is way more natural to 
simply pack those things into the very tiddler to which they belong. Two 
different modeling approaches. I don' see a tiddler getting "cluttered" by 
that, especially nto with tiddler fields being only editable as simple 
text-inputs.

I think having comments stored at tiddler-data-fields is by far easier 
index, search and relate to that very tiddler... using standard filtering 
procedures, if not a lot easier, than putting these things under some 
deferred system-namespace. What about renaming a tiddler and similar 
things? Store fields where they belong, as much as you can. A tiddler is a 
moveable entity... and should pack with all the things that go with it, is 
what I think.

But, above all, I see no particular reason why only the text field of a 
tiddler should be indexable via json. Would there be a technical constraint 
to doing so?

Best wishes, Tobias.

Jeremy,

Thank you, that makes much more sense now and probably makes the filters 
more powerful. Now I just need to find places where I can take advantage of 
it.

Tobias,

I would never have thought of removing the indicies like that, thanks!

Think "logs", "comments"... all those kinds of things.


Is that different from just using fields? Fields may get very cluttered I 
guess, but having a connected data tiddler or something would be equivalent 
to just using a data tiddler in addition to the original one wouldn't it?
I would think that for logs and the like having the tiddler foo and then 
storing logs in $:/data/foo/logs and comments in $:/data/foo/comments or 
some similar setup would be less cluttered than having the information 
stored in the tiddler foo itself. I think that would make it easier to 
search and use things like display templates for the data. This would be 
even better if the system tiddler browser gets implemented ( 
http://tiddlywiki.com/prerelease/#%24%3A%2Fcore%2Fui%2FMoreSideBar%2FExplore

Please note, I was not at all referring to states.
Rather, I was suggesting data pertaining to an exact tiddler, that are not 
to "clutter the timeline",
except for per-tiddler lists of related, well, data... of different kinds 
(see linked discussion 
).

Think "logs", "comments"... all those kinds of things.

Best wishes, Tobias.

The curly braces indicate a transcluded filter operand. The overall action
is to take the tiddler title stored in `$:/palette`, get all the indices of
the data properties within it, and then sort the indices.

It would take all tiddlers tagged "foo", and accumulate all the indices
within them, and then sort the list of indices.

No, the data comprising a data tiddler is always stored in the "text" field.

I'm not so convinced. If we store state within content tiddlers then it
makes it harder to share those content tiddlers in a multi-user scenario.

Best wishes

Jeremy.

In ...

http://tiddlywiki.com/#FilterOperator%3A%20indexes

What exactly is *{$:/palette}*...

[{$:/palette}indexes[]sort[title]]

interpreted as? ...being a text-reference. I presume it is translated as: take 
whatever is defined in *{$:/palette}* as a text-reference to a data-tiddler.

What would happen with a construct like this:

[[tag[foo]indexes[]sort[title]]

...assuming there were multiple data tiddlers tagged *foo*?

Also, can any field of a tiddler be used as a DataField or does it always 
have to be the *text* field? As asked / indicated here 
, I 
think it can prove beneficial to store related data entries at the exact 
tiddler to which they relate, yet not in its text-field.

As for deleting indexes from a DataTiddler, here is one way to do it...

Saving And Loading A History Snapshot @ tb5 


Look at *\define deleteSnapshot()* and notice how the index is *set* on 
button click, however with no *setTo* value being specified. This results 
in setting an undefined value, ergo deleting the index from the data.

Best wishes, Tobias.

Hi Jed

The order does matter for filters that work as "selectors" rather than
strict "filters". For example, the "indexes" operator selects all the data
indices present in the tiddlers whose titles are in the current list.

Do filters get executed in order? I hadn't encountered or noticed it 
before, but rearranging the filter breaks the output, 
[indexes[][$:/data/Acronyms]regexp:title[(?i)$(thisSearch)$]] doesn't work. 
I had assumed that each operation was done independently and then the 
intersection of the resulting sets (or union for ORing filters) was given 
as the output.
In most cases this wouldn't have any effect, but it seems to be the case 
here. 

Is that what is happening? If so that may have been why nothing I was 
trying was working out. It makes sense but either it isn't mentioned in the 
documentation or I am missing it.
