* Initial commit Everything is draft. * Fix test execution * Fix and test missing target handling * Use the ubertransclude widget for the wikitext transclusion syntax * Changed transclude widget in binary parser to ubertransclude * Add a test for custom action widgets * Don't worry about ordered attributes The changes in0bffae2108
mean that we don't need to explicitly maintain the ordered attributes * Remove need to explicitly clear widget mapping variable when invoking overridden widget * Use ts- prefix for system slot names * Add a definition for the value widget just so that it doesn't cause errors Of course, it doesn't actually need to be a JS widget, it could be a wikitext widget... * Add support for positional parameters * Ubertransclusion positional parameters should be based on name, not position * Add support for shortcut syntax for positional transclusion parameters * Importvariables should skip parameters widgets * Refactor transclude widget before uberfying it * Refactor ubertransclude functionality into transclude widget * Replace ubertransclude widget with transclude widget * Add wikitext shortcut for new-style function definitions * Allow brackets to be omitted for function definitions with no parameters * Add pragma rule for parameters declarations * Remove erroneous "tag" property * Add support for accessing function parameters as name/value pairs * Be as permissive as possible with parameter names Previously restricted to upper and lower case, digits and dash and underscore * Rewrite some tests to use the shortcut syntaxes * Mustn't allow commas in parameter names * Fix crash when transcluding an undefined variable Thanks @pmario See https://github.com/Jermolene/TiddlyWiki5/pull/6666#issuecomment-1114692359 * Unquoted parameters should not eat a succeeding comma Fixes #6672 * Remove extraneous code * Allow the let widget to create variables starting with $ * Fix addAttributeToParseTreeNode handling of ordered attributes * Reuse attribute objects when executing custom widgets * Fix importing of function definitions * Fix parameter handling * Introduce genesis widget for dynamically creating widgets See the "RedefineLet" test for a contrived example of usage * Change tiddler separator used in wikitext tests Underscore looked ambiguous; I kept typing dashes by accident * Cache parse trees when transcluding variables * Fix bug with empty strings ignored in $tw.utils.stringifyList/parseStringArray I will pull this out into a separate PR. Fixing it doesn't cause problems for the core but I imagine it might cause issues for 3rd party code. * Fixes to enable the transclude widget itself to be overridden There are two big changes here: Replace the previous "ts-wrapper" mechanism, which we had been using to redefine custom widgets inside their definitions to prevent recursive calls. Now we've got the genesis widget we can instead control recursion through a new "$remappable" attribute that allows the custom widget mechanism to be skipped. We also extend the slot widget to allow a depth to be specified; it then reaches up by the indicated number of transclusion widgets to find the one from which it should retrieve the slot value. * Fix genesis widget example * Use enlist:raw to preserve duplicates * Don't create variables with value undefined for missing parameters * Fix variable retrieval bug with test harness * Improve recursion detection While retaining backwards compatibility * Experimental support for custom filter operators Just as we can define custom widgets we can also define custom parameterised filter operators * Add visible transclusions component and demo Very useful to see transclusions explicitly Makes a good demo of a super-complicated widget override. * Genesis widget should pass raw attributes onto child widget... ...so that it can more efficiently handle refreshing itself. * Use consistent parse tree node property for params * Extend transclude widget to work with old-style macros and use it for the macrocall shortcut syntax * Clarify that the recent changes allow functions to be invoked with the double bracket syntax In other words, the transclude widget distinguishes between functions and macros and handles the parameters appropriately * Make the macrocall widget delegate to the transclude widget * Switch to using \procedure to define new-style macros, and \function for custom filter operator functions I now need to update the OP! * Fix visible transclusion example * Remove obsolete code Left over after refactoring * Better backwards compatibility for legacy recursion marker Fixes the problem with tag dropdowns @btheado * Fix stringifying/parsing string arrays containing newlines A very old bug. Fixes the ActionListOpsWidget problem @btheado * Transclude: replace paramNames/paramValues with more robust JSON payload More details at https://github.com/Jermolene/TiddlyWiki5/pull/6666#issuecomment-1123719153 * Rename internal "unknown" filter operator so that users cannot invoke it * Detect recursion by tracking widget tree depth The old recursion marker approach was very slow, and didn't catch test cases like editions/test/tiddlers/tests/data/transclude/Recursion.tid * Use \widget for custom widget definitions, and remove need for angle brackets Need to do some refactoring of all those isFunctionDefinition/isProcedureDefinition/isWidgetDefinition flags into a single property * Rename <$value> widget to <$fill> * Require $$ for custom widgets, and that overridden JS widgets must exist See https://github.com/Jermolene/TiddlyWiki5/pull/6666#issuecomment-1133637763 * Fix invocation of JS macros * Experimental update of the parse-tree preview visualisation An experiment to try out using the new JSON operators for rendering the JSON parse tree that we get back from the wikify widget. As usual with these experiments, this one is going to require quite a lot more work to finish up: * The formatting is via direct styles rather than classes * The formatting for attributes and properties is not yet completed * The same thing needs to also be done to the widget tree preview * Procedures and widgets inherit whitespace trim setting from their definition * Missed off22e7ec2381
* Require period prefix for custom filter operator functions To ensure that custom filter operators cannot clash with future core operators. * Allow custom functions to be invoked as attributes * WIP * Remove unneeded test tiddler * Make is[variable] and variables[] operators resilient to fake widgets * Fix importvariables to work with setvariables as well as set (they are aliases) * Add support for $:/tags/Global * Remove accidental commit6cc99fcbe3
* Add utility function for parsing macro parameter definitions * Introduce true global variables The basic idea is that if we don't find a variable `foo` then we fallback to retrieving the value from the tiddler `$:/global/foo`, if it exists. This allows us to replace the usual importvariables-based mechanism for global definitions, avoiding cluttering up the variable namespace with every macro. In order to permit subprocedures to be overridden, we also introduce a mechanism for conditional definitions: preceding the word definition|procedure|function|widget with a + causes the definition only to occur if the specified variable doesn't already exist. In the next commit we'll apply this mechanism to the tabs macro * Convert the tabs macro into a global So far it appears to be totally backwards compatible... In practice, I think maybe this and the conversion of the other macros should go into a separate subsequent PR. * Change to `?` for conditional definitions * Fix tabs global so it doesn't crash when viewed directly * Test showing how to un-override a core widget * Cleaning up afterf636349007
* Minor cleanups * Clean up unknown filter * Introduce function operator for calling functions Can invoke any functions, not just those start with a period. And can pass zero parameters (in contrast when invoked as a custom filter operator there's no way to omit the first parameter). * Use underscores for new system fields for global variable tiddlers For consistency with `_canonical_uri`; unlike many system fields, the behaviour of these fields is baked into the core JS code. * Refactor $parameters widget The objective is to add a $depth attribute so that it is possible to reach up to retrieve the parameters of ancestor transclusions. However, doing so requires changing the encoding of parameter names so that it is not possible for a user parameter to clash with an attribute like $depth. So now we have to double up dollars on any attribute names seen by the parameters widget, just like with the transclude widget itself. * Fix refreshing of global variables Global variables access within attributes will automatically trigger a refresh if the attribute text changes, but that wasn't happening for transclusions. * Remove support for $:/tags/Global It is not needed now that we have true global variables * Typo fromf513b403fe
* Make slot fill data available to transclusions Allows transcluded content to dynamically process <$fill> widgets within the calling transclusion * Mark docs as v5.3.0 * Simplify metaparameters implementation * Fix typo * Adjust naming of transclusion metaparameter * Fix up handling of slot/fill for custom widgets Previously we were wrapping the body in an implicit `<$fill $name="ts-body">` widget * Add format:json operator I've been finding this useful for debugging, and it kind of goes with the JSON operators * Docs: JSON operators and tweaks to genesis widget * Docs: format:json Also tweak to the behaviour of format:json if the input string is not valid JSON * Fix #6721 * Revert "Fix #6721" This reverts commitb216579255
which was committed to the wrong branch * Fix new selection tracker to return relative coordinates * Make use of type attribute consistent * Docs: Transclude widget * Simplify the fill widget We can rely on the default processing in the base class * Slot widget: be more defensive about negative depth values * Parameters widget: Be defensive about negative depths * Protect against excessively recursive functions * FIx transcluding of functions This first implementation concatenates the results of the filter (with no separator) and then wikifies the result. The test in this commit is quite interesting... * Tweak semantics of JSON operators to match #6932 This allows us to later bring in the optimisations without breaking backwards compatibility. * Revert obsolete changes to boot.js * Fix inadvertent whitespace change * Remove tests related to obsolete changes to boot.js Should have been part of2f494ba152
* Revert changes to parse tree preview This implementation requires #6666 * Add test to show that global widgets need not use the _parameters field * Disable overriding core widgets in safe mode * Coding style tweak * More comments * Fix caching of parse variables/macros/procedures * Transcluded functions should operate on the entire store * Refactor filter recursion detection to avoid an unneeded wrapper function * Fix error in25312b3e32

Fixes #6998 * Fix macrocall refresh issue It turns out that this.transcludeTitle is always truthy, even if we are transcluding a variable Fixes #7001 * Filter run prefixes should use widget.makeFakeWidgetWithVariables * Docs typo Thanks @twMat * Docs: clarify function operator invocation See discussion at https://github.com/Jermolene/TiddlyWiki5/issues/6991#issuecomment-1301703599 * Docs: Update \define pragma to cover named ends * Docs: move tiddlers to correct directory * Add support for named end markers for procedures, functions and widgets * Docs note about nested macro definitions * Rename test * Fix detection of empty transclusions See https://talk.tiddlywiki.org/t/exploring-default-tiddler-links-hackability-in-v5-3-0/5745/25?u=jeremyruston * New test missed offa45349cc99
* Refactor wikified function tests * Refactor function invocation * 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 * Fix positional parameters in widget.evaluateVariable() This should clear up the remaining anomalies in #7009, let me know how you get on @btheado * Remove 5.2.8 release note * Fix nonstandard initialisation code for fill/parameter/slot widgets * Update modification times of doc tiddlers So that they are at the top of the recent tab * Update 5.3.0 release note * Remove custom CI step for this branch * Restore standard sitetitle

Adds the following properties to the wiki object:
|
|
|
|
* `eventListeners` is a hashmap by type of arrays of listener functions
|
|
* `changedTiddlers` is a hashmap describing changes to named tiddlers since wiki change events were last dispatched. Each entry is a hashmap containing two fields:
|
|
modified: true/false
|
|
deleted: true/false
|
|
* `changeCount` is a hashmap by tiddler title containing a numerical index that starts at zero and is incremented each time a tiddler is created changed or deleted
|
|
* `caches` is a hashmap by tiddler title containing a further hashmap of named cache objects. Caches are automatically cleared when a tiddler is modified or deleted
|
|
* `globalCache` is a hashmap by cache name of cache objects that are cleared whenever any tiddler change occurs
