I’m fixing this now to show how the tabs macro can be changed to
accommodate the change, but we may yet decide to reverse out the change
in order to maintain backwards compatibility.
One problem with changes like this is that there’s no easy way to find
out where it impacts the core UI. The tabs macro is now fixed, but
perhaps there’s more obscure things that are still broken in the core.
If we do opt to reverse the change to preserve backwards compatibility,
we could add a way to explicitly trigger the new behaviour. For
example, a new attribute `updateState=“yes”`.
Yet another alternative is to make completely new alternative to the
list widget with revised semantics, that authors can opt-in to. For
example `<$loop>`. (There was another issue we discussed a year or two
ago about adding support for an index variable which may be a candidate
for fixing at the same time).
Fixed a side-effect of 03519c14b0 from
@matabele whereby the current tiddler is overwritten by the
`<$tiddler>` widget, which means that it is not accessible when
rendering the caption of the tab.
This causes a problem with eg the “Add Plugins” modal where it breaks
the count on the tabs.
The new importvariables widget imports macro/variable definitions from
the specified tiddlers and makes them available to its children.
Allows us to split PageMacros up into separate tiddlers.
We still support loading macros from $:/core/ui/PageMacros to help
people upgrading.
Fixes#644 and #559
