Re: [tw5] How do I get a list of tiddlers from a filter and then manipulate the fields / tags on each in a loop?

[Xavier Cazin]

Hi Andrew,

Action widgets can only be triggered by a user action, like clicking on a
button, dropping a tiddler, or loading the wiki. They can't be triggered
by, say, the $list widget, eventhough you may use a $list to produce some
of the action strings.

\define done()
<$action-listops $tags="done"/>
<$action-sendmessage $message="tm-copy-to-clipboard" $param=<>/>
<$list filter="[tag[bar]]">
  <$action-setfield foo="done"/>

\end

<$checkbox checkactions="<>"> Is it done?

In the example above, the list of actions to be executed when the box gets
checked are grouped in a macro.
The list of actions to be executed are most often passed to the control
widget via an *actions* attribute.

Best,
-- Xavier

[tw5] How do I get a list of tiddlers from a filter and then manipulate the fields / tags on each in a loop?

[leeand00]

I'm aware there are widgets that will modify them...for instance 
<$action-listops>
can modify fields, but I don't know how to use a filter like 
[tag[some-tag-they-all-have]sort[create-or-mod-date]] and to loop through 
them performing a similar action on each.

I'd also like to be able to include an index, or obtain them sorted by 
create-or-modification date.

Thank you,
Andrew J. Leer
