Major Improvements

Conditional Shortcut Syntax

ajouté a new shortcut syntax for concisely expressing if-then-else logic. This is the first of a new type of wikitext syntax based on tokens delimited with <% and %>. We plan to introduce other structures using the same format such as a "case" statement.

These new token-based shortcuts allow a richer structure and expressivity than existing features such as widgets or pragmas. For example:

<%if [<animal>match[Elephant]] %>
  It is an elephant
<%elseif [<animal>match[Giraffe]] %>
	It is a giraffe
<%else%>
	It is completely unknown
<%endif%>

Behind the scenes, the conditional shortcut syntax is rendered as the equivalent ListWidgets.

Explicit Templates for the ListWidget

ajouté support for <$list-template> and <$list-empty> as immediate children of the $ListWidget widget to specify the list item template and/or the empty template.

This new feature is designed to replace a common pattern of using the emptyMessage attribute of the ListWidget to render complex wikitext that thus has to be quoted. Working with wikitext within quotes is awkward and error prone. The new structure can be somewhat faster because it allows the empty message to be parsed in advanced of rendering.

For example:

<$list filter=<<filter>>>
	<$list-template>
		<$text text=<<currentTiddler>>/>
	</$list-template>
	<$list-empty>
		None!
	</$list-empty>
</$list>

Note that the emptyMessage and template attributes take precedence if they are present.

Joiners for the ListWidget

ajouté a join attribute to the $ListWidget widget to insert a short piece of text between list items. This is both easier to use and faster than using the counter attribute for the same purpose. So if your list looked like this:

<$list filter=<<filter>> counter="counter" variable="item">
<$text text=<<item>>/><$list filter="[<counter-last>match[no]]" variable="ignore"><$text text=", "/></$list>
</$list>

You can replace it with:

<$list filter=<<filter>> variable="item" join=", "><$text text=<<item>>/></$list>

If the joiner text that you need is long and awkward to write in an attribute, you can use the new <$list-join> widget. Like <$list-template> and <$list-empty>, it must be an immediate child of the $ListWidget:

<$list filter=<<filter>> variable="item"><$text text=<<item>>/><$list-join>, and <em>also</em> let's not forget </$list-join></$list>

jsonset operator

ajouté jsonset Operator for setting values within JSON objects

QR Code Reader

étendu QR Code plugin to be able to read QR codes and a number of other bar code formats

Translation improvements

Improvements to the following translations:

• Chinese
• Polish
• Spanish

Plugin Improvements

• corrigé Comments Plugin to use predefined palette colours
• amélioré Evernote Importer Plugin to support images and other attachments
• ajouté $floating attribute to Dynannotate Plugin to support popups that do not disappear when another part of the screen is clicked. Instead they have to dismissed manually

Widget Improvements

• corrigé ImageWidget encoding for more image types
• étendu ImageWidget to add a "usemap" attribute
• amélioré the ScrollableWidget to allow the scroll position to be bound to a tiddler, so that changes to the tiddler affect the scroll position, and vice versa

Usability Improvements

• mis à jour editor preview button to automatically focus the editor
• amélioré file type names in the export menu

Hackability Improvements

• étendu all the relevant core widgets to allow arbitrary data-* attributes and style.* attributes to be applied to the generated DOM nodes. This is useful for passing data to the EventCatcherWidget
• étendu jsonextract Operator, jsonget Operator, jsonset Operator and jsontype Operator to allow negative indexes into arrays to be counted from the end of the array
• amélioré the default page layout to better support CSS grid and flexbox layouts
• amélioré the editor to use grid layout, simplifying customisation

Bug Fixes

• corrigé ordering of Vanilla stylesheets
• corrigé missing closing tag in tag-pill-inner macro
• retiré invalid "type" attribute from textarea elements generated by the EditTextWidget
• corrigé editor "type" dropdown state tiddlers
• corrigé handling of "counter-last" variable when appending items with the ListWidget
• corrigé upgrade download link in Firefox
• corrigé refreshing of transcluded functions
• corrigé resizing of height of textareas in control panel
• corrigé encodebase64 Operator and decodebase64 Operator to work properly with binary data
• corrigé WidgetMessage: tm-open-window when opening an existing window to bring it to the front and focus it
• corrigé behaviour of last Operator when zero items selected
• corrigé incorrectly setting focus on field name input field when deleting field using the delete field button
• corrigé Table-of-Contents Macros to not show expander icon for a sublist that has all children excluded
• corrigé overflow of CodeMirror Plugin editor within grid container
• corrigé wikitest parser removing whitespace when parsing pragmas
• corrigé tooltip for editor add field button
• corrigé plain text parser being susceptible to the CodeBlockWidget being redefined
• corrigé pragmas not working within the action string of several core macros

Node.js Improvements

• corrigé a significant flaw in the synchronisation algorithm used by the client-server configuration. The flaw could lead to tiddlers temporarily disappearing from the browser

Performance Improvements

• amélioré performance of predefined patterns with all Operator
• mis à jour favicon format to PNG

Developer Improvements

• amélioré global hook handling to support removing hooks
• ajouté some useful npm scripts to package.json

Infrastructure Improvements

• amélioré Continuous Integration tests to use Playwright to run our browser-based tests
• ajouté an automatic build of the external core TiddlyWiki at https://tiddlywiki.com/empty-external-core.html
