I switched this optimisation off back in
ed35d91be6, in October 2013, as part of a
big refactoring of the parsing and widget mechanism. I’ve been meaning
to switch it back on for some time.
My rough measurements suggest that this optimisation can reduce
rendering time by 5-10%.
Typically for JavaScript, initialising an object as an array doesn’t
break anything because an array is an object. Anyhow, it should be an
object in this case.
Previous changes since 5.1.7 broke the documented semantics by no
longer returning true when the versions match. It affected the upgrade
process, making it impossible to upgrade to a later pre-release (ie
where the version numbers in the upgrade.html match those in the file
being upgraded).
Also reviewed and updated the calls to checkVersions.
@felixhayashi I think that this effectively reverts the change you
original submitted. Are you OK with it?
when the tiddlers are not listed in the list field, sort them by title
nonetheless, otherwise we get a real poor taglist from
**$:/core/ui/TagTemplate**
If the target tiddler of the draft is missing (as happens after
clicking “new tiddler”), then we count the draft as modified if the
text is not empty.
Also we count the the draft as modified if the draft title has been
changed
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.
Re-introduces the “tw-auto-save-wiki” message. The previous approach of
automatically triggering autosave whenever a tiddler changed meant that
changing configuration changes in control panel was triggering an
autosave. Using the explicit message gives us better control of the
situations in which we’ll autosave.
Now we solve the earlier problem of there being outstanding tiddler
change events at the time that we process the “tw-auto-save-wiki” by
deferring the autosave until the outstanding change event comes in.
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 were parsing the boot tiddlers, making them into a widget and then
refreshing the widget tree. The problem is that subsequent chances to
the boot tiddlers themselves wouldn’t be picked up as part of the
refresh.
Now we indirectly parse those UI boot tiddlers through a transclusion,
which does get refreshed in the desired way.
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
