* Fix Bug #7054: Reuse of $:/core/ui/EditTemplate/fields broken
This fixes Bug #7054 by creating a new variable
`safeNewFieldValueTiddlerPrefix` that is always set to a valid,
temporary prefix. This variable is used within `$action-deletetiddler`.
If the passed `newFieldValueTiddlerPrefix` variable is empty a new
prefix will be generated by the same logic that creates the original
`newFieldValueTiddlerPrefix` variable.
To be even more defensive, the prefix-filter was prepended with another
prefix filter that limits matches to `$:/temp/NewFieldValue`. This
prevents a bogus but non empty value in `newFieldValueTiddlerPrefix`
to delete arbitrary tiddlers.
* Add a default for `newFieldValueTiddlerPrefix`
This fixes a problem that was identified while fixing bug #7054. If the
tiddler `$:/core/ui/EditTemplate/fields` is transcluded directly and
`newFieldValueTiddlerPrefix` is not set, it will be generated. This
makes sure that this value is defined. It can not be redefined
unconditionally because if this tiddler is transcluded from
`EditTemplate.tid` these two tiddlers must agree on the same prefix
because the clean-up is duplicated between `EditTemplate.tid` and
`fields.tid`.
This would make `safeNewFieldValueTiddlerPrefix` obsolete, but I leave
it in there to make the macros safe and prevent any problems if the
`newFieldValueTiddlerPrefix` is unset by a later change.

* Fix popup location for tables
This commit introduces the `popupAbsCoords` option to the $button widget
and implements an absolut coordinate format.
Coordinates for popups are stored in the format `(x,y,w,h)`. These
coordinates are relative to the offset parent of the element that
defines the popup.
This commits adds a second format `@(x,y,w,h)`. Coordinates specified in
this format a relative to the pages root element.
The `popupAbsCoords` option of the $button widget enables the use of
this coordinates.
* Unify the declaration of the RegEx for parsing the popup-position
The regular expression was declared in three locations with the same
content. This commit supplies a new function `parseCoordinates` in
`popup.js`. This function returns the parsed coordinates and understands
the classic/absolute coordinates.
This function is used in `reveal.js` and `action-popup.js` to parse the
coordinates.
* Add documentation for coordinate systems
* Consolidate creating coordinate strings
The Popup object now contains a `buildCoordinates` method that can be
used to build coordinate strings. It takes an "enum" for the coordinate-
system to use. This makes everything easily extensible and prevents the
use of magic values.
* Add tests for `parseCoordinates` and `buildCoordinates`
* Add `tv-popup-abs-coords` to `collectDOMVariables`
This will make the absolute coordinates available for the
`DraggableWidget` and the `EventCatcherWidget`.
* Add documentation for the `tv-popup-abs-coords`
... to the `DraggableWidget` and the `EventCatcherWidget`.
* Fix crash when generating a static version of the TW
The Popup class is not initialized in `startup.js` if `$tw.browser` is
not true. After having consolidated the facilities for parsing
coordinate strings into `popup.js` this breaks because the static build
needs to parse coordinate stings even if no Popup module is initialized.
This commit solves this problem by making `readPopupState`,
`parseCoordinates` and `buildCoordinates` static methods of `popup.js`.
It also adds a comment to these functions to show that these can be called
safely even if the Popup-Class is not initialized.

* Fix bug with checkbox widget and `list` field
The `list` field is stored as a list and frozen against modifications,
and getFieldList() returns it directly without creating a copy. So
before we modify it, we need to make a copy so we're not modifying a
frozen list. This bug doesn't manifest with custom fields, which are
stored as strings, only with the built-in `list` field.
* Fix checkboxes referencing non-existent tiddlers
This fixes the "tiddler is undefined" error when a checkbox's listField
property references a tiddler that doesn't (yet) exist.
* Better logic for checkbox listField handling
If the field contains an array, then it's almost certainly referenced
elsewhere and needs a defensive copy made. If it contained a string,
then it's safe to modify without making a defensive copy.
Since https://github.com/nodejs/node/issues/40537 users are more likely to encounter IPv6 connections.
IPv6 URLs require square brackets around raw addresses.
With this change VS Code correctly hyperlinks the message `Serving on http://[::1]:8080`
* Implement insertafter operator (like insertbefore)
Currently, the behavior of insertafter if the target is not found is to
append the inserted tiddler to the end of the list, like insertbefore
does. In the next commit, we'll add a suffix to customize what both
insertafter and insertbefore do when the target is not found.
* Add failing tests for insertafter suffixes
Also includes tests for insertbefore suffixes (start/end), since we'll
be implementing both of those at the same time.
* Add start/end suffixes for insertafter/before
The tests that exercise the start/end suffixes now pass.

* Fix for Bug #6618
This Commit fixes Bug #6618. It is a little bit more complicated than
using one tiddler to store the new value for a field. Because the
following can happen:
* The user types "not-a-date" into the field value of a simple text field.
* The user now selects a field name that uses a HTML5 date editor. The
Editor will show no date because the value cannot be parsed.
* The user saves the tiddler by clicking the checkmark.
Now the date-field contains the value "not-a-date" but the user was not
aware that this will be added. The edit control showed no date (because
the value was invalid) and the user assumed the field was empty and
won't be added to the tiddler.
To prevent this, every kind of field editor gets its own storage tiddler.
Its name is derived from the SHA256-hash of the name of the tiddler that
is returned by the Field Editor Cascade. That way every editor in the
cascade is only seeing its input. As long as the default setup (with one
default editor) is used, everything works like in 5.2.1.
This commit also fixes the bug that the after adding a field the
field-type input box was not focused again.
* Update Documentation for Field Editor Cascade
The fix for bug #6618 makes the handling of the tiddler backing the edit
operation much more complicated. See previous commit "Fix for Bug #6618"
for more details.

* fix: exclude the SJCL library when saving
@Jermolene said:
The construction -[type[application/javascript]library[yes]] is used in the core as a rather clumsy way to exclude the SJCL library when saving. The same construction is in the usual $:/core/save/all filter too.
It's possible that we should review unintended side effects of that behaviour, but here we should leave it alone.

* Use "yes" and "no" for checkbox indeterminate attr
This makes the "indeterminate" attribute of the checkbox widget work the
same way as other boolean attributes of other widgets.
* Fix bug with invertTag attribute
One place in the checkbox widget code was checking invertTag for
Javascript truthiness rather than the value "yes", which could have
produced incorrect results if anyone wrote invertTag="no". Fixed.

* Show server response as error message in put saver
I'd like to use this on Tiddlyhost so users can get more informative
error messages if the put save fails for whatever reason.
This would make the put saver a viable replacement for the legacy
upload saver, which is what Tiddlyhost uses currently.
I'm not sure what standard WebDAV servers do, but I would guess they
don't provide any response body for put requests, and hence this
patch would have no impact for a standard WebDAV server. (That said,
it would be a good idea to test it to make sure there aren't any
unexpected regressions for WebDAV or other put saver compatible
services.)
* Access http response status directly in put saver
There's no need to extract it from the error string created inside
tw.utils.httpRequest if we can get it directly from the xhr object.
* Add 'Save starting' notification for put saver
There are two related changes here:
1. Add a 'Save starting' notification for the put saver, similar to
the upload saver. Not sure if it was intentionally omitted for
the put saver, but it seems reasonable to have the two be
consistent.
2. Send the 'Save starting' notifications in both upload and put
save right before the actual request is sent. While testing I
noticed that the save might have failed before the "Save
starting" notification appeared which doesn't seem useful.
* Docs for CheckboxWidget list and filter modes
This documents the `listField` and `filter` attributes.
* Tests for checkbox widget list mode
* Implement checkbox list mode
* WIP on implementing filter attr for checkboxes
* Improve CheckboxWidget documentation
* Refactor checkbox tests: move function to top
The big findNodeOfType function belongs at the top of the describe
block, so that the checkbox tests are more compact and easy to read.
* Move checkbox widget tests to end of file
The checkbox widget tests are long and involved, so we'll move them to
the end of the file so they aren't a huge block of code you need to read
past to find the next test.
* Improve formatting of CheckboxWidget docs
The \define() calls that are short enough to fit on one line should be
put on one line, for readability. The ones that are quite long have been
kept on multiple lines, for readability.
* Added more passing tests for checkbox widget
* Add some failing tests for checkbox widget
The filter mode where neither checked nor unchecked is specified (in
which case an empty filter result means false and a non-empty result
means true) is not working yet.
* Make failing tests pass
* Uncomment (and improve) test for field mode
We're now ready to start working on making this test pass. (There was
also one small mistake in the test, which this commit corrects).
* All tests now passing
* No indeterminate checkboxes in simple modes
The simple checkbox modes (field and index) should not produce
indeterminate checkboxes. That should be reserved for the advanced modes
(list and filter).
* Minor improvement to unit tests
* Allow indeterminate checkboxes in list and filter modes
This change may require some tweaks to the unit tests to be able to test
it properly.
* Slightly easier to read tests
* Two more tests for list mode
* Greatly simplify unit test code
Turns out there's no need to jump through Object.getPrototypeOf hoops.
* Minor simplification of unit test
* Add tests for indeterminate in list & filter modes
With this, the set of tests is complete.
* More tests to specify list mode behavior
* Unfocus tests so all tests run
* Update docs to say "new in 5.2.3" insetad of 5.2.2
* Move checkbox widget tests into their own file
The test-widget.js file was getting too long with all the checkbox
tests added, so we'll move the checkbox tests into their own file.
* Add checkbox widget tests for index mode
This commit also adds tests for index list mode (with a listIndex
attribute that will parallel the listField attribute) but leaves them
commented out because they don't pass yet: the code that implements the
listIndex attribute hasn't been written yet).
* Add listIndex attribute to checkbox widget
* Remove code that lets checkboxes be indeterminate
This reverts commit 6afcb151be. We will
add this code back in a later PR.
* Remove indeterminate tests for checkbox widget
We're currently not allowing indeterminate checkboxes, so there's no
need for the tests that check for them.
* Document listIndex attribute of CheckboxWidget
* adds class tc-checkbox-checked when checked
* equivalent to #2182 (RadioWidget)
* also applies `tc-checkbox` to checkboxes by default, always
* Move macro definitions inside example text
Since the wikitext-example-without-html macro creates a new parsing
context, it's safe to have macro definitions inside it. That makes these
examples a lot easier to write, and to read.
* Remove all mention of indeterminate checkboxes
Also improve the documentation a little bit: mention what happens in
list mode if neither checked nor unchecked is specified.
* Move filter mode to bottom of checkbox docs
The `filter` attribute should be under both `listField` and `listIndex`
rather than being between them. The documentation for filter mode should
similarly be after the `listIndex` documentation.
* Improve docs for `class` attr of checkbox widget
This brings the wording of the `class` attribute more in line with how
it's worded in the RadioWidget docs.
* Fix bug with list tiddlers
If neither checked nor unchecked was specified, then the behavior should
be "empty = false, non-empty = true". But if *both* are specified yet
neither is found, then the checkbox should be unchecked (false). It had
been falling through to the "non-empty = true" behavior, which was wrong.
* Improve listIndex example of checkbox widgets
* Remove unused function from test-widget.js

This reverts commit c920960942.
* Add new class `tc-edit-fieldeditor`
This class must be added to input and select elements that are used as
field editors. This class reduces the line height of the input element
if it is displayed within the `tc-edit-fields` part of the edit

This allows the same input and select elements to be used for editing
and adding fields.
* Add the new class `tc-edit-field` to the docs
The example in `Customizing EditTemplate Field Rendering` now uses the
new CSS classes.

* Allow the rendering of fields to be extended
This commit extends the `$:/core/ui/EditTemplate/fields` tiddler to
use a new cascade (Field Editor Cascade) to allow customizing the
rendering of the field editor.
It provides a default element for the cascade that displays the standard
EditTextWidget as a fallback. That way, the implementation is completely
backwards compatible. The `currentTiddler` and `currentField` variables
are available in the transcluded tiddler. This has the additional
benefit, that not only the `EditTextWidget` can be used. The user can
use a dropdown-list or even something completely crazy. As long as it
can be put into a tiddler that updates the field, it will be fine.
* Make `select` Tags in Fields look like the rest
This patch updates the CSS to make `tc-edit-texteditor` usable on
`select`-tags as well.
I'm not sure what `-webkit-appearance: none;` is for, but it hides the
DropDown-arrow in Chrome and makes the select-tag hard to discover. I've
changed the css to only apply it to the input tag. Maybe it can be
removed altogether.

The problem was that v5.2.0 trimmed the whitespace from $:/core/templates/store.area.template.html which we'd previously been relying on during the import.
This change still allows v5.2.2 to import encrypted pre-v5.2.0 wikis
Fixes#6330
* Add a snippet to visualise faulty stylesheets
As discussed in https://github.com/Jermolene/TiddlyWiki5/issues/6176, a faulty stylesheet can propagate and break several other stylesheets. This can be tricky to debug in a wiki with a lot of custom stylesheets.
This wikitext snippet will display a list of the stylesheets created/modified by the user and will display a red cross next to the one causing a parsing error.
