* Cleaned up jasmine test suite output
Also testing for expected log messages, instead of just letting them print
to the console every single time, constantly making you think there's some
warning you need to worry about, and making all those dots not line up nicely.

* removed four tiddlers because of dead links.
* Changed the dead link in Tiddlydrive add-on by Joshua Stubbs to link to the projects github instead.
* Fixed titltes in the community tabs macro.
* Sorted all entries into their new categories, updates tags accordingly and moved tid files into new folders according to their new category.
* final edit for sorting
The image was received with a transparent background, but I adjusted it to give it a white background to ensure it is readable with all colour schemes.
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.
* Update docs for Set Widget
This updates the docs for Set Widget to add a tip regarding a common source of misunderstanding for users, i.e. using Filtered List Variable Assignment and being confused as to why the value of the variable is in double square brackets.
* Corrected typos
* made private methods limited to module scope
* moved private methods to file bottom
* changed tests to run comperable array functions in parallel
* added comments
Documents the change to macro parsing from #5205
This builds on documentation changes made in the tw.com branch and is therefore based on that branch, but should not be merged before 5.1.23 is live.
* 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.
One tiddler had been renamed since the deprecation warning tiddler was
created, and there were also a couple of minor punctuation and/or
spelling errors.
* Tag trim operator as a string operator
With the new functionality of the trim operator in 5.1.23, it's now a
general-purpose string manipulation tool. So it should be given the
"String operators" tag so that people see it in the same list as
removeprefix and removesuffix, etc.
* Document suffix of trim operator
* Jeremy's original version of the event widget
* Renamed to eventcatcher, added modifier key support and mouse button support as variables
* Reveal widget: update popup position when state tiddler updates

* Revert "Add Kookma plugins as resources"
This reverts commit 199fce3a08.
The ButtonWidget documentation refers to a "state" attribute, but this
should probably be "set". The name "state" appears to be an artifact
from when the setTitle, setField, and setIndex attributes were added to
the widget; at one time they were called stateTitle and so on, and then
they were renamed to setTitle instead, but not every instance of "state"
was found and renamed to "set". This is one such instance, now fixed.

* 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.
* Fix 'if' condition syntax in Actions workflow
Strings in expressions need to be in single quotes:

* fix#4800 - remove network communication to product hunt
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.
* switch boolean logic in new parameters
Use renameinTags and renameInLists instead of dontRenameInTags and dontRenameInLists respectively. This avoids users having to think through double negatives, as well as corresponds better to the setting in $:/config/RelinkOnRename
* Updated docs for revised parameters for tm-new-tiddler
* Styles and templates for visual changes to Saving methods listing
* Color coding saver methods according to delivery
* Changes to tags and few tiddlers
- The tag InternetExplorer has been changed to [[Internet Explorer]]
- A tag for Edge is added
- Reclassified TiddlyServer as DIY instead of App
The existing criteriion for classification is unclear. Here is my reasoning for the change. An app is something user can simply install and run. Like TiddlyDesktop or Tiddloid. A DIY is something user has to install additional runtimes for. Thus Nodejs is a DIY. In the same vein, TiddlyServer is a DIY
* Adding Twexe
* Reversing accidental changes to StoryList
* Restyling Download button and Card Size
* Removing "Read more" links
Entire card is now clickable
To give visual clues regarding the clickability of card, title will change color to blue on card hover
* Removing margins from elements under link and adding padding instead.
Why this change? Margins are not "clickable". Having margins under <a> tag means there are minute dead areas where the mouse pointer will change shape, is not clickable and degrade user experience. Paddings are "clickable"
* The `!has[tags]` filter didn't work because "tags" is an array
The negated `has` filter only considered empty strings, but not empty
arrays (such as the `tags` field).
* Add tests for `has` filter operator with array-like fields (tags, list)

Update documentation for modals to include the custom class introduced in #4485, as well as the footer and subtitle fields that don't appear to be documented.
* First commit
* Add throttling of saves
Now we refuse to save a tiddler more often than once per second.
* Wait for a timeout before trying again after an error
* Modest optimisations of isDirty() method
* Synchronise system tiddlers and deletions from the server
Fixes two long-standing issues:
* Changes to system tiddlers are not synchronised from the server to the browser
* Deletions of tiddlers on the server are not propagated to browser clients
* Make sure we update the dirty status even if there isn't a task to perform
* Replace save-wiki button with popup sync menu
* Remove the "Server" control panel tab
We don't need it with the enhanced sync dropdown
* Add indentation to the save-wiki button
* Fix spacing in dropdown menu items
* Switch between cloud icons according to dirty status
* Add a menu item to copy syncer logs to the clipboard
* Improve animated icon
* Remove indentation from save-wiki button
@pmario the annoying thing is that using `\trim whitespace` trims significant whitespace too, so it means we have to use <$text text=" "/> when we need a space that won't be trimmed. For the moment, I've removed the indentation but will keep thinking about it.
* Further icon, UI and copy text tweaks
Move the icons and styles from the core into the TiddlyWeb plugin
* Clean up PR diff
* Tweak animation durations
* Break the actions from the syncer dropdown into separate tiddlers
@pmario I think this makes things a bit easier to follow
* Refactor syncadaptor creation and logging
The goal is for the syncadaptor to be able to log to the same logger as the syncer, so that the "copy syncer logs to clipboard" data is more useful.
* Don't transition the dirty indicator container colour, just the SVG's colour
* Only trigger a sync for changes to tiddlers we're interested in
Otherwise it is triggered by the creation of the alert tiddlers used to display errors.
* Restore deleting local tiddlers removed from the server
(I had commented it out for some testing and accidentally commited it).
* Guard against missing adaptor info
* We still need to trigger a timeout when there was no task to process
* Avoid repeatedly polling for changes
Instead we only trigger a timeout call at if there is a pending task (ie a tiddler that has changed but isn't yet old enough to save).
* Lazy loading: include skinny versions of lazily loaded tiddlers in the index.html
* Introduce _is_skinny field for indicating that a tiddler is subject to lazy loading
* Remove savetrail plugin from prerelease
It doesn't yet work with the new syncer
* Make the savetrail plugin work again
* Clear outstanding alerts when synchronisation is restored
* Logger: only remove alerts from the same component
Missed off 9f5c0de07
* Make the saving throttle interval configurable (#4385)
After switching Bob to use the core syncer the throttle interval makes saving feel very sluggish compared to the message queue setup that I had before.
The editing lock that I use to prevent conflicts with multiple users doesn't go away until the save is completed, and with the 1 second delay it means that if you edit a tiddler and save it than you have to wait one second before you can edit it again.
* Tweaks to appearance of alerts
* Exclude temp tiddlers from offline snapshots
Otherwise alerts will persist
* Tweak appearance of status line in dropdown
* Update release note
* Web server: Don't include full path in error messages
Fixes#3724
* In change event handler check for deletions
* Disable the official plugin library when the tiddlyweb plugin is loaded
* Hide error details from browser for /files/ route
See https://github.com/Jermolene/TiddlyWiki5/issues/3724#issuecomment-565702492 -- thanks @pmario
* Revert all the changes to the relationship between the syncer and the syncadaptor
Previously we had some major rearrangements to make it possible for the syncadaptor to route it's logging to the logger used by the syncer. The motivation is so that the "copy logs to clipboard" button is more useful.
On reflection, changing the interface this drastically is undesirable from a backwards compatibility perspective, so I'm going to investigate other ways to achieve the logger sharing
* Make the tiddlyweb adaptor use the syncer's logger
So that both are availavble when copying the syncer logs to the clipboard
* Update release note
* Support setting port=0 to get an OS assigned port
Quite useful
* Update code comment
* UI: Use "Get latest changes from server" instead of "Refresh"
* Add getUpdatedTiddlers() method to syncadaptor API
See https://github.com/Jermolene/TiddlyWiki5/pull/4373#issuecomment-573579495
* Refactor revision handling within the syncer
Thanks @pmario
* Fix typo in tiddlywebadaptor
* Improve presentation of errors
See https://github.com/Jermolene/TiddlyWiki5/pull/4373#issuecomment-573695267
* Add docs for getTiddlerRevision()
* Remove unused error animation

* Add tests for backlinks
* Add backlinks indexer
* Use backlinks indexer in getTiddlerBacklinks if available
* Extract link extraction into its own method
This way we can provide an arbitrary parse tree, rather than just a
title, which will allow us to compare lists of outgoing links between
versions of a single tiddler
* Use new extractLinks method in backlinks indexer
...rather than copy-pasting the implementation
* Remove ES6-isms
TiddlyWiki needs to work with browsers that only support ES5
* Fixes issue with #4504 and importvariable copying
ImportVariables widget was using $tw.utils.extend to copy the
variables from temporary set widgets into itself. However,
$tw.utils.extend does NOT behave like Object.assign. It not only
copies all self-owned variables over, but also all variables
in that object's prototype chain. This led to some redundant copying,
and a problem where some variables might show up more than once
(like transclusion).
Fixed now. importvariables widget does its own copying, since it
can't rely on $tw.utils.extend to do the right job, and it can't
count on Object.assign to be there.
* Added test to prevent reversion of #4504
* Slight corrections to new importvariables test
* add a new-line before the log text to increase readability of the test output
* make eslint, jslint happy
* make eslint happy
* add more listops tests
* new listops filter tests
* remove new-line
* make eslint happier.
* revert eslint settings
* Changed importVariable to store its ownvariables
Before, importVariables was creating a setWidget for every single variable it would find in its tiddlers, and it would create a long-ass call tree. Now, instead, it just accumulates the variables in itself.
* Can't use Object.assign
Learned the hardway while working on tw5-relink that Object.assign
doesn't exist in IE11. Using $tw.utils.extend instead.
* Retaining setWidget transclusion flexibility
* One more test to verify mixing sets and macros
add 3 new tiddlers, add 1 "enlist" test, fix all tests that failed, because 3 new tiddlers where added. stopped ESLint to complain about global vars, fix some mixed-tab-space indent typos.
* process.exit() only exist in a node.js environment
* updateInterval has been removed from upstream
From upstream commit:
b6eb9a4d5e
* Update Jasmine to 3.4.0
* Reuse the evalInContext helper
* Fix expected parse result to match the actual result
* 'describe' cannot be nested inside 'it' blocks
Jasmine started to explicitly raise an error in these cases since:
https://github.com/jasmine/jasmine/pull/1411
* Be consistent about how to refer to library files
* Update link to Jasmine's official website
... because there is another macrocall inside.
This was introduced by the commit 'Fix sizes of SVG icons in documentation' (SHA: 9395d75671) where this probably slipped through in a regular expression replacement session.
I searched through the codebase and the other replacements of this type are ok.
I (Flibbles) changed it so that lists generated by stringifyList
would always be compatible with a filter parser, but since lists
are not, and never will be, a subset of filters, there isn't a
point.
More importantly, wrapping negative numbers like "-7" in brackets
would mess up some math stuff.
* add "delayed" option to tm-focus-selector message
this delays the focussing for the time of the animation duration if delayed="yes" or delayed="true"
this is useful when navigating the story river up and down with keyboard shortcuts and the shortcuts focus the title input if a navigated tiddler is in edit mode -> navigation doesn't jump but stays smooth
* Update rootwidget.js
* Update WidgetMessage_ tm-focus-selector.tid
* add preventScroll="true" tip
* Transform GitHub saver to work with GitLab as well
You can choose which provider you want to use, the data is given in the
same place.
I tried to avoid code duplication, so service providers' unique
properties are in separate files, the settings of the selected provider
are loaded.
In two fields I am not sure that it fits into the current structure:
* module-type: gitservice
Which module is a `gitservice` type, it will be listed in the
drop-down menu.
* default-api-url: https://gitlab.com/api/v4
The default URL to access the provider's API.
This is just a sketch, not a final version, suggestions for modification
are welcome!
* Rename saver from GitHub to GitService, update docs
* Split GitHub and GitLab to separate savers, apply common lingo
Sadly, it doesn't seem to make much sense to search for common parts in
the code, because there might be a Git service that is very different
from the GitHub API (such as BitBucket). Therefore, I feel that Git
savers are not able to share other than the translations.
I deleted the defaults values from the translations and set it to the
text entry because they should not depend on the translations.
* Add more information about the password field
It is not clear how to create a personal access token, thus added a link
to the help pages. In addition, GitLab only accepts personal access
token, GitHub also accepts the password, so I made this clear.
* Extract commit message to lingo
* Fix indentation
* Use improved base64 encoder
Fix conflict with a06acc4eb8
Fixes#4082
This version removes selective updating of the tag index, instead completely clearing the index on each update. I'm investigating restoring that optimisation.
The test rig previously used a simplified implementation of shadow tiddlers which broke with the new indexing engine. There was also a problem that made that even if indexers were disabled they were still initialised.
This PR fixes both problems, in preparation for fixing #4082
See discussion at https://groups.google.com/d/msgid/tiddlywiki/526754d5-8786-49cd-aaa1-c77311670116%40googlegroups.com:
The history here is that in v5.1.14 we added an "actions" attribute to the checkbox widget that specified an action string to be specified whenever the state of the checkbox changed. The same action string is executed regardless of whether the checkbox was checked or unchecked.
Then in v5.1.16 we merged https://github.com/Jermolene/TiddlyWiki5/pull/3182 which added the "uncheckactions" attribute. The difference between the two is that the uncheckactions are only executed if the checkbox is unchecked. The main "actions" attribute is executed before any actions in "uncheckactions", which makes it possible to arrange things so that the "actions" attribute sets things to the checked state while the "uncheckactions" attribute overwrites those changes to set things to the unchecked state.
In retrospect, it would have made more sense to have also added a "checkactions" attribute that was executed only if the checkbox was checked. I'll investigate adding it for v5.1.20.
Regarding the bulleted tag pills; they should probably also be removed in place of text but I see value in keeping them for the sake of being able to easily peek at what they tag. We should probably have a section under Ctrlpanel>Settings where any startupaction-tiddlers are listed but since we don't yet, then the mentioned tag pills could perhaps remain.... except for the one in the PR.
Include = before each number in the Mathematics Operators examples,
so that people get used to seeing that in math examples where dupes
are likely.
Only the Mathematics Operators tiddler really needed to be changed;
the example tiddlers for individual operators were already using =.
Fixes#3979.
* First pass at modular wiki indexes
An exploratory experiment
* Fix tests
* Faster checking for existence of index methods
We don't really need to check the type
* Use the index for the has operator
* Fix typo
* Move iterator index methods into indexer modules
Now boot.js doesn't know the core indexers
* Fix up the other iterator index functions
* Fix crash with missing index branch
* Limit the field indexer to values less than 128 characters
* Fallback to the old manual scan if the index method returns null
* Sadly, we can no longe re-use the field indexer to accelerate the `has` operator, because the index now omits tiddlers that have field values longer than the limit
Still need to make the index configuration exposed somehow
* Rearrange tests so that we can test with and without indexers
We also need to expose the list of enabled indexers as a config option
* Test the field indexer with different length fields
So that we test the indexed and non-indexed codepaths
* Update TiddlyWiki5 Squared by Iannis Zannos.tid
Link no longer works. Changed it to the github page.

Tested that this is the correct code.
* Add uniquetitle macro
This macro is a wrapper on the $tw.wiki.generateNewTitle function to return a unique name, it has been requested multiple times in the forums.
* Add documentation tiddler for uniquetitle macro
* Add uniquetitle macro examples
* Change name from uniquetitle to unusedtitle for clarity
The title isn't unique, just not currently used in the wiki.
* Update uniquetitle to unusedtitle

* Fix a typo
There are other ways we could add maths to TW5 (including @EvanBalster's awesome https://github.com/EvanBalster/TiddlyWikiFormula) but the approach here has the merit of simplicity because it reuses the existing filter evaluation mechanism. That means that it's not ordinary "2+2" maths, it's a unique list processing language...
Docs to come
