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
A bunch of little changes that together enable external image support.
Try:
```
tiddlywiki editions/tw5.com --verbose --build externalimages
```
Then open `externalimages.html`, look for the images in the more/types
tab of the sidebar, open them and verify that they are set with an
external SRC attribute, not a data URI.
We’re also reverting to the old custom dropdown. Using the select
widget didn’t work out because it couldn’t cleanly work with a text box
allowing custom types to be specified.
In 5.0.12-beta, if you change the current language setting then the
current sidebar tab setting is lost. This was because the qualified
title generated for the tabs was incorporating the current language
title, by virtue of a trick used in the PageTemplate to set the
“languageTitle” variable to a field of the current language plugin.
This trick left the current tiddler set to the current language, and
this current tiddler was still in force for the transclusion of the
page template segments.
In practice, if you look at TabsMacro you’ll see that the width of the
tab content is wrong, and will usually overflow the container. Next
step is to fix that by using flexbox…
1. Moved some methods out of boot.js because they are not needed until
after bootup
2. Added alternate message for editing an overridden shadow tiddler
3. Minor style tweaks
Fixes#580
Seems much better, especially since the chevron gives us two clear
visual states (left vs. right). The hamburger doesn’t really have a
commonly accepted way of indicating whether the menu is currently open
or not.
By rearranging the `[all[]]` operator we are able to ensure that shadow
tiddlers get processed before ordinary tiddlers. This makes it easier
to create custom stylesheets that override the core.
We get a significant speed improvement of >10% by rearranging filter
operators to bring to the front the operators likely to reduce the size
working list.
