* corrected [!is[draft]] to be a proper complement
* Ensuring [is[draft]] and [!is[draft]] are complements
* Made [is[draft]] more analogous to .isDraft()
* Support case insensitive matching in prefix/suffix operators
Support `caseinsensitive`/`caseinsensitive` suffixes in the following
filter operators:
* prefix
* suffix
* removeprefix
* removesuffix
The suffixes have the same behaviour as in the match operator.
Closes: #6407
* Do not filter titles if suffix/removesuffix operand is empty
Issue: #6407
* Support direct style attributes on the element widget
* Fix tests
Not all parse tree nodes have an "orderedAttributes" member (eg. the error message generated at 5613bcc884/core/modules/widgets/transclude.js (L73-L75))
* Ensure ordering isn't insertion dependent if orderedAttributes is missing
* Add docs
* feat: extend tm-open-window to support optional top and left position for new browser window
* fix: whitespace correction
* Update WidgetMessage_ tm-open-window.tid
This reverses an August 2015 change in 68e15c10641e2eda1e64cf29954786a07326a920; the original rationale was wrong: there is nothing related to the navigator widget in the implementation of the tm-rename-tiddler message
* feat: add support for animationDuration attribute of paramObject for tm-scroll message
* docs: added docs for animationDuration attribute of tm-scroll message
* fix: use .utils.hop instead of Object.hasOwnProperty()
* fix: do not check if object before calling utils.hop()
* fix: syntax
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
* Support macro params in filter run prefixes and support substitution for variables set by filter run prefixes
* feat: add support macro parameters and variable substitution for all filter run prefixes
* fix: rename options argument to opts for disambiguation
* feat: add support for macro params to cascade filterrun prefix
* fix: issues with drag and drop (false positives in detection for files being dropped) introduced by Chrome 96
* fix: call dragEventContainsType method more consistently.

This PR adds support to trigonometry operators, allowing to create spider graphs and other geometric shapes with filters.
* Adds the missing trigonometric filter operators
This PR adds support to the missing trigonometric filter operators (cos, sin, tan, acos, asin, atan, atan2), allowing to create spider graphs, [pie charts, donut charts, polar charts](https://ffoodd.github.io/chaarts/pie-charts.html) and other geometric shapes with filters, which was previously not possible without add-ons.
Example :
`[[2]cos[]] = -0.4161468365471424`

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.
Also cleaned up the template to remove unneeded tiddlers
* Optimise wiki.sortTiddlers()
* Remove local changes to test-filters.js that have now been made on master
Makes the subsequent merge easier

* Add support for JSON-formatted tiddler store, and make it the default
The change to `getTiddlersAsJson()` is to allow experimentation
* Move JSON tiddlers into their own store area, and fix support for encrypted tiddlers
Also add a dummy old-style store area for backwards compatibility
The current arrangement is that JSON tiddlers will always override old-style tiddlers.
* Use the deserialiser mechanism to decode the content
* Refactor $:/core/modules/deserializers.js before we start extending it
Cleaning up the helper function names and ordering
* Drop support for the "systemArea" div
It was only used in really old v5.0.x
* Update deserializer to support JSON store format and add some tests
* Life UI restrictions on characters in fieldnames
* Add another test case
* Correct mis-merge
* Remove toLowerCase() methods applied to fieldnames
* Insert line breaks in output of getTiddlersAsJson (#5786)
Rather than have the entire store on one line, insert a line break
after each tiddler.
* Refactor #5786 for backwards compatibility
* Only read .tiddlywiki-tiddler-store blocks from script tags
Prompted by @simonbaird's comment here: https://github.com/Jermolene/TiddlyWiki5/pull/5708#discussion_r648833367

* Fix problems with building single-file wiki using external-js template
* core/templates/external-js/tiddlywiki5-external-js.html.tid,
core/templates/external-js/save-all-external-js.tid,
core/templates/external-js/save-offline-external-js.tid
core/templates/external-js/load-external-js.tid:
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
Popup an error message instead of disabling the button when export
core cannot be performed.
* Revert "Correct text & fill colors on some disabled buttons"
This reverts commit e7dbb7e712.

* Use a mimeTypesFilter instead of the mimeTypes and mimeTypesPrefix attributes
* Updated refresh handling
* Syntax cleanup
* 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
handle certain types of arguments. Now it uses the same one that the
widget parser uses. Less code!
* style changes and removing weird switch statement
That switch statement made more sense in an earlier iteration.
* comment improvements
* oops, wikirule macrocalls could do ONE thing better
* '=' wasn't allowed for widget macros, but why?
Now they're allowed for both widget macros and macrocall macros.

This is needed for Bob to use the core to generate tiddler fileInfo
I don't know if this is the best way to make the hook, but it works for what I need
* update th-make-tiddler-path arguments
the value is the current path, the parameter passed in is the original unmodified path so it is available to subsequent hooks
Fixes#5246. Now the reduce operator and :reduce filter run prefix will
both return empty output when their input is empty, so that both can be
chained together with the else operator or :else prefix.
* made private methods limited to module scope
* moved private methods to file bottom
* changed tests to run comperable array functions in parallel
* added comments
* Changed the filterrunprefixes to use LinkedList
* Testing for Linked List
* Finishing touches to LinkedList
* Minor corrections to link-list coding style
* Corrected for sneaky bug in linkedList
Default with no suffix is pre-5.1.23 behavior, escaping all Unicode
characters for maximum compatibility (avoids encoding issues). New
"rawunicode" suffix allows passing through Unicode characters U+0080
and up unchanged, for cases where you know your tools are handling
encoding correctly and you want less verbose escaping.

* First pass at refactoring filter code to support named filter run prefixes
* Remove filter prefix for now
* renamed module type and filter run prefixes
* Moved inline handling for no filter run prefix to 'or' filter run prefix.
* Added error handling for undefined filter run prefixes
* Add suffix and parameter to trim operator
Fixes#4809
* Unit tests for new trim operator parameters
* Mention trim operator in 5.1.23 release notes
* Address review comments
* Move regex escaping into utils.js trim functions
This way the trimPrefix and trimSuffix functions from utils.js are safe
to call without regex-escaping their parameters, which should make them
easier to use from other parts of the Javascript code.
* Initialize draft tiddler with empty text
Otherwise, when the tiddler has a meta file,
$tw.utils.saveTiddlerToFile will call fs.writeFile with the content
to write as `undefined`. Depending on the version of Node, this
results in the string "undefined" getting saved or a TypeError.
* Remove what seems to be a leftover debug log
Most astral-plane text is emojis like U+1F4DA BOOKS (📚), but some
languages like Osage have their alphabet entirely in the supplementary
multilingual plane as well. For proper support of languages like Osage,
and newer emojis, the UTF-8 decode and encode functions need to properly
handle codepoints above U+FFFF, which are represented by a surrogate
pair in Javascript strings.
From RFC 2616 - "Hypertext Transfer Protocol -- HTTP/1.1", Section 4.2, "Message Headers":
Each header field consists of a name followed by a colon (":") and the field value. Field names are case-insensitive.
