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.
Mistakenly, I had changed the tiddler widget to refresh itself when the
value of the target tiddler changed. This is not in fact necessary; it
only needs to refresh itself when the identity of the target tiddler
changes.
Fixes#744
Previously we were using a message `tw-auto-save-wiki` to trigger an
autosave. The message was generated by certain UI actions such as
saving a tiddler. The trouble was that the message was being processed
before the wiki change event for the accompanying change had had a
chance to percolate. The end result was that the dirty indicator was
staying lit when using autosave.
The new approach abandons the autosave message and instead triggers the
autosave in the wiki change event when a relevant change occurs.
One happy side effect of these changes is that the dirty indicator now
works as expected with the client server edition - ie, when typing in a
draft tiddler the dirty indicator will flash briefly, and then clear
when the sync mechanism has completed saving the draft.
Fixes#717
The issue was that under Windows we generate text nodes that contained
CRLF as a linebreak (rather than just LF as usual).
The subtle problem is that when these strings are placed in the DOM via
createTextNode(), the CR character is treated as a printable character,
not whitespace. When creating DOM notes with innerHTML or as part of a
static HTML document the HTML parser will strip out the CR characters.
The hacky solution is to manually remove CRs before building the text
node.
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 $:/core/ui/PageMacros to help
people upgrading.
Fixes#644 and #559
A bunch of little changes that together enable external image support.
Try:
```
tiddlywiki editions/tw5.com --verbose --build externalimages
```
Then open `externalimages.html`, look for the images in the more/types
tab of the sidebar, open them and verify that they are set with an
external SRC attribute, not a data URI.
Previously, widgets were reading variables from themselves or their
cascaded ancestors. That means that if a widget sets a variable and
then reads the same variable, it will get the same variable back. That
sounds reasonable, until you consider a widget that wants to modify a
variable - eg the tiddler macro. For example:
```
<$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.
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
Replace this with a $tw.wiki.isModifiedTiddler(title) as part of the
wiki object. This allows it to be used outside of the current Wiki which
can change.
Should only display the confirmation if the shadow tiddler has not been
overridden in the first place. It checks this by looking for the
existence of a modified field for which the default system based shadow
do not have until a user changes them.
This addresses the second line item on issue #570
We will need new translations for the added string
`ConfirmEditShadowTiddler`
When saving a tiddler we check to see if the tiddler has changed
(isModified) if it hasn't then bounce the event to tw-cancel-tiddler
instead.
Addresses first line item in issue #570
We need to send messages to the parent so that we don’t set up an
infinite loop by sending `tw-navigate` messages. Also we need to pass
along the target of the navigation.
Because:
* It doesn't work well with TW5's refresh mechanism, which relies on
being able to regenerate any portion of the DOM as required; this
frequently causes inline handlers to be re-executed at unexpected times
(see
http://tiddlywiki.com/static/TiddlyWiki%2520for%2520Developers.html)
* It mixes TW5 version-specific JavaScript with user content
* In multiuser environments there is a security risk to importing or
viewing tiddlers you didn't author if they can have JavaScript in them
As described here: https://groups.google.com/d/msg/tiddlywikidev/AWvXz7RMIC4/gFF5crN2UJoJ
Providing a name for the new tiddler message only works if a skeleton tiddler already exists. If not, "New Tiddler" is taken. This change fixes that in that the provided name is taken even if there is no skeleton.
We re-use some of the existing syncer mechanism. It was already keeping
track of changes to tiddlers in the store when working with a tiddler
syncadaptor. Now it also tracks changes when there is no syncadaptor,
allowing us to provide a warning if there are unsaved changes.
Causes the wiki to be autosaved whenever clicking “done” after editing
a tiddler. Only works with savers that support autosave. We should
probably make autosave configurable
Previously, when displayed content is hidden by the reveal widget there
was an optimisation such that the content was retained in the DOM but
hidden using CSS, so that it could be shown again quickly.
It turns out that a sideeffect of that optimisation is that clicking
through all the sidebar tabs leaves them all active, so that they all
need to be refreshed whenever a character is typed in an editor.
This commit suppresses the optimisation, so that hidden content is
removed from the DOM and the render tree.
