Hi Jed,
good to hear that it helped you. I took a look at the evaluateExpression
code and overall it looks pretty good. There are two things I want to
mention though:
* It is nice to see that you are using the setVariable function of the
widget, however when doing this, be aware that variables set in the
makeWidget actually overwrite the variables set by the setVariable
function since the former creates set-widgets inside the widget (if i am
not mistaken).
* If you use a current version of TW (by current I mean anything younger
than 30 days), you should be able to change
widgets.children[0].invokeActions({});
to
widgets.invokeActions({});
This is also wise from a programming standpoint, since it does not
assume any structure that may or may not be present within the widgets
object and the children.

Thank you! I got it to work, and learned a lot more about how
tiddlywiki works. The updated code is on github if you are interested.
The goal is to have something like a button that can trigger action
widgets or macros, but instead of the event that triggers them being a
mouse click it is a change to some set of tiddlers or fields.
There is a filter that determines the tiddlers that will be acted on,
a list of actions to take on each of those tiddlers and a filter that
determines what changes will trigger the actions.
I haven't added the list of tiddlers to listen to for changes, and I
need to add some field to all of them so that it can't change one of
the tiddlers it listens for and end up in an infinite loop. I haven't
tested it when it makes a lot of changes yet, so it may not be
practical because of how long the updates take, but if it does work I
think it could be very useful.
