* 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.
* Add `main` and `article` roles to stories and story.
* Support `role` and \aria-checked` in buttons, and integrate with sidebar tabs.
* Add `region` role to sidebar, and set caption as `aria-label`.
* Add accessibility roles and labels to static templates.
* Update test fixtures with new ARIA tab attributes.
* Fix: eventcatcher widget - variables can be undefined
* Fix: selectedNode can be an svg where offsetLeft ... are undefined
* Make check for offsetLeft short
* remove second collectDOMNodeVariables
* Documentation for indeterminate checkboxes
* Unit tests for indeterminate checkboxes
* Implement indeterminate checkboxes
* Simplify indeterminate checkbox example
* Slightly simplify refresh logic for indeterminate
That five-line if statement can be turned into a simple assignment.
* 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.
* fix: formatDateString with [UTC]xxx didn't use passed date
* test: for formatDateString UTC
* fix: not possible to test internal date without hijack
Expected '20220410073037515' to be '20220410073037516'.
* fix: hour
* 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

The problem was that the innerwiki template included the tiddler $:/plugins/tiddlywiki/railroad, which was omitted from the wiki. Unexpectedly, missing tiddlers were rendered by the jsontiddler widget as an empty object {}. The fix is to always include the title when the tiddler is missing.

Fix#5343. Exclude client-server plugins in tiddler imports and to
specify a working URL for loading tiddlywiki5.js from local disk.
Mirror save/all and save/offline templates in the regular server
edition.
Fix#4717 (tiddlywiki5-external-js.html.tid)
* core/modules/saver-handler.js:
Need the change to make single file autosave work with the external-js
template.
* editions/server-external-js/tiddlywiki.info:
Provide external-js related build targets.
* core/language/en-GB/Snippets/ExtJSReadme.tid:
Temporary doc to supplement TW5.com's external-js section. Demonstrate
that upgrade could be done on single-file wikis with an externalized
TW core.
* core/language/en-GB/Snippets/GetTiddlyWikiJS.tid:
Documentation. Meant to be included in every wiki and to help end
users acquire tiddlywiki5.js.
* Pre-configure save-wiki template for end-users
* Remove the newline character at the end of the file.
* Trim "template" value in saveWiki()
* Safeguard the code from extraneous whitespaces in transcluded result.
* Rename and add versioning to downloaded tiddlywiki core JS
* Rename "tiddlywiki5.js" to "twcore-VERSION.js"
* Preload $:/config/SaveWikiButton/Template tiddler with the required
external-js template value.
* Update external-js user documentation
* Add "download tiddlywiki core JS" menu item to the "cloud" button.
* Update build's target defintions associated with external-js template.
* Move the user doc to the tw5.com edition.
* Coding style update
* Undo template name changes
* Correct text & fill colors on some disabled buttons
* Add new "export tiddlywiki core" button under page control tools
This new button can export tiddlywiki's core JS from user's wiki as
long as the wiki is served with the regular "root" template. The
button will be ineffective, thus disabled, if the core has already been
externalized by the "external-js" template.
With this button, a full standalone html wiki can obtain the matching
core JS without TiddlyWiki on node.js. Once this is done, the html wiki
can be converted to using the "external-js" template.
* Alternate version of "save tiddlywiki core for offline use"
This version will fire up a "Save File" dialogue box when clicked,
instead of directing the user to a helper doc for further instruction.
It achieves this by using the "download" attribute of the <a> html tag.
It works on most modern desktop browsers, but older browsers (e.g. IE)
may display the file instead.
* Adjust font-weight to match other menu items
* Merge two user documentations into one
* Add user-browser-cache=yes to --listen command
* Update "export tiddlywiki core" button hint
* Simpler implementation for switching btw online/offline core URL
Shave off one template by using filtered transclusion to control
online/offline core URL.
* Update user doc
Update the user doc to clarify that build index step is not needed to
initialize a new wiki.
* Rename twcore to tiddlywikicore
* Reformat the user doc
* Rework export-tiddlywikicore button

* Replace references to mimeType with content type for consistency with existing documentation. Update documentation for DropZone widget
* double quotes are no longer escaped in html bodies
* changed tiddlyweb's html-div-tiddler; documentation
French version still needs a translation though
* Replace css-escape-polyfill.js with escapecss.js utility module
* Add $tw.utils.escapeCSS() method and invoke that function within the
escapecss operator.
* Add test cases for the "escapecss" filter operator
* Fix $tw.boot.doesTaskMatchPlatform() so it works as expected if
a module's export.platforms contains more than one values
* Add missed files to the last commit
We can now pass arrays of rule classes to the parser constructor, overriding the rules that would normally be used by the parser.
This allows us to create custom variants of the wikitext parser with their own content type.
It could also provide a basis for a new Markdown parser based on our existing wikitext parser but with new rules.
The default behaviour is unchanged, but if you write "yes" to
$:/UploadWithUrlOnly then it will assume it's possible to upload
with a blank username and password, as long as the host is set.
The motivation is to support a upload plugin compatible upload
service that uses some method to authenticate other than the legacy
upload plugin user/password params.
Without this patch, the user would need to enter something random in
the user and password fields for TW to decide the upload plugin can
be used.
* wikirules now use better macrocall parser
Before, wikirules would use a deficient macrocall parser which couldn't

That switch statement made more sense in an earlier iteration.
