* Introduce new widget helper function to evaluate variables.Functions are evaluated as parameterised filter strings, macros as text with textual substitution of parameters and variables, and procedures and widgets as plain text
* Refactor the function operator and unknown operator to use the new helper
* Use the new helper to evaluate variables within filter strings, thus fixing a bug whereby functions called in such a way were being returned as plain text instead of being evaluated
* Refactor the transclude widget to use the new helper
* Update tests
* correction of the toc and toc-body macro: tiddler without toc-link field can now be overriden + nested the macros
* reverted macro nesting
.. to be able to override the toc-body macro
* reverted tabs to spaces
* Allow boot code to remain as tiddlers
* Sync up with tiddlywiki5.html
* Add \whitespace trim
* Add download-full-wiki button
* Simplify ExportTiddlyWikiCore code
No longer needs the if-boot-code-is-missing part of the code.
* Replace space btw icon and button text with CSS
* Added failing tests for #7155
* Pass getVariable options through to the widget method. Fixes#7155
* Whitespace fix
* Added tests to verify macro parameters work inside filter, reduce, and sortsub operators
* Fix Bug #7054: Reuse of $:/core/ui/EditTemplate/fields broken
This fixes Bug #7054 by creating a new variable
`safeNewFieldValueTiddlerPrefix` that is always set to a valid,
temporary prefix. This variable is used within `$action-deletetiddler`.
If the passed `newFieldValueTiddlerPrefix` variable is empty a new
prefix will be generated by the same logic that creates the original
`newFieldValueTiddlerPrefix` variable.
To be even more defensive, the prefix-filter was prepended with another
prefix filter that limits matches to `$:/temp/NewFieldValue`. This
prevents a bogus but non empty value in `newFieldValueTiddlerPrefix`
to delete arbitrary tiddlers.
* Add a default for `newFieldValueTiddlerPrefix`
This fixes a problem that was identified while fixing bug #7054. If the
tiddler `$:/core/ui/EditTemplate/fields` is transcluded directly and
`newFieldValueTiddlerPrefix` is not set, it will be generated. This
makes sure that this value is defined. It can not be redefined
unconditionally because if this tiddler is transcluded from
`EditTemplate.tid` these two tiddlers must agree on the same prefix
because the clean-up is duplicated between `EditTemplate.tid` and
`fields.tid`.
This would make `safeNewFieldValueTiddlerPrefix` obsolete, but I leave
it in there to make the macros safe and prevent any problems if the
`newFieldValueTiddlerPrefix` is unset by a later change.
