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.
Make good use of "$:/core/modules/utils/base64-utf8/base64-utf8.module.js"
* Add a new base64Encode()
* Both of base64Encode and base64Decode work for Nodejs and Browsers
This adds options.wiki to the object sent to the generateTiddlerFilePath
The function generateTiddlerFilePath can take a wiki in the options object, but generateTiddlerFileInfo doesn't pass the wiki to it.
* add escapecss filter
this filter would allow creating valid css classes from titles containing special characters
we assign a class to an element using `encodeuricomponent[]` so that the class name is encoded
in a stylesheet we create the classname by `<title>escapecss[]` which applies the uri encoding and escapes characters that need to be escaped
* Update encodings.js
* refactor tagToCssSelector, add escapeCssSelector
* use escapeCssSelector
* escape using CSS.escape if it's available
* Update encodings.js
* revert factoring out escapeCssSelector
... this makes the animation when inserting tiddlers / navigating to tiddlers in the pop storyview less jumpy
it simply sets `overflow-x` to `hidden` for the time of the insert-animation
* 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
It turns out that the `localeCompare` function used by `compareStateText()` is very, very slow. Replacing it with a straightforward equality test makes one of my test rigs be 10x faster...
Note that this PR reverts the behaviour of match/nomatch to that before #3157. That change was not backwards compatible in that the switch to localeCompare meant that é === e, now it doesn't again.
Approximtely 50% speed improvement in tests opening a storyview with 8,000 entries.
(I've deferred the indentation adjustments until the next commit so that the git diffs are clearer)
