* 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)
Fixes#3875
* Use .json files (instead of .tid) for any tiddler whose fields contain values that can't be stored as a .tid file
* Save application/json tiddlers as .json files
* Refactor most of the file handling as re-usable utilities
If the path was not specified, RSOD error occurred when we wanted to
download the wiki:
Uncaught TypeError: Cannot read property 'substring' of undefined
* 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
* Change uniquetitle to unusedtitle
* Fix a typo
@BurningTreeC I think this might have been a typo in your recent refactorings; if you look back at an old version such as c0c1b557eb/core/modules/widgets/reveal.js then there is no sign of this fallback.
Fixes#3874
