* Support direct style attributes on the element widget
* Fix tests
Not all parse tree nodes have an "orderedAttributes" member (eg. the error message generated at 5613bcc884/core/modules/widgets/transclude.js (L73-L75))
* Ensure ordering isn't insertion dependent if orderedAttributes is missing
* Add docs
* Support macro params in filter run prefixes and support substitution for variables set by filter run prefixes
* feat: add support macro parameters and variable substitution for all filter run prefixes
* fix: rename options argument to opts for disambiguation
* feat: add support for macro params to cascade filterrun prefix
* $let widget added and tested
* Documentation for $let, doc improvements for $vars
* let properly avoids refreshing when possible
* $let Changes as recommended by others
* Removed superfluous super method call
Also improved $let test
We were using `String.prototype.replace()` without addressing the
wrinkle that dollar signs in the replacement string have special
handling. This caused problems in situations where the replacement
string is derived from user input and contains dollar signs.
Fixes#2517
This is quite a big change: a new way to invoke action widgets.
The advantage is that it solves #2217 and #1564, a long running problem
that prevented us from adding action widgets to widgets that modify the
store.
This commit adds the new technique for the button and keyboard widgets,
but also extends the select widget to trigger action widgets for the
first time
Allow widgets to choose not to propagate actions. This is important for
widgets that themselves trigger actions.
Note that this change will cause problems with any existing
5.1.8-prerelease plugins that call `invokeActions()`.
Preserves compatibility with existing invokeActions call in button widget by creating a separate 'invokeActionCall' function to carry out the recursion. Triggering all descendants permits use of action widgets inside list widgets or macros. Also makes it possible to add triggering capability to select widget.
There are still some warnings about making functions in a loop, but
I’ll fix those as a separate pull request because the fixes are more
than typographic errors.
Previously, widgets were reading variables from themselves or their
cascaded ancestors. That means that if a widget sets a variable and
then reads the same variable, it will get the same variable back. That
sounds reasonable, until you consider a widget that wants to modify a
variable - eg the tiddler macro. For example:
```
<$tiddler tiddler={{!!report}}>
<$transclude mode="block" />
</$tiddler>
```
Here we first evaluate the `{{!!report}}` reference, which involves
reading the currentTiddler variable, looking up the tiddler, and
retrieving it’s `report` field. The next the tiddler widget is
refreshed, it will use the newly set currentTiddler as the basis for
resolving the `{{!!reference}}` reference.
The fix is to get variables from ancestors, but continue to set them on
ourselves.
