Giuseppe Lippolis	4845c10d88	fix(ExpressionNode): ensure _subscriber do not change during ValueChanged	4 years ago
Steven Kirk	76667dbd0d	Finished adding nullable annotations to Avalonia.Base.	4 years ago
Steven Kirk	0bda763518	Added nullable annotations to Avalonia.Data. (#7105 ) * Added nullable annotations to Avalonia.Data. * ExpressionObserver root can be null.	4 years ago
Steven Kirk	4d01dacd77	Remove copyright headers. Some of our files had them, some didn't. They serve no purpose legally so best to remove the ceremony.	6 years ago
Steven Kirk	d3f8d08a47	Make sure OneTime bindings unsubscribe. `OneTime` bindings unsubscribe when the first value is pushed, meaning that they unsubscribe _during_ `ExpressionNode.StartListeningCore`. Make sure we handle this by: - Setting `_listening = true` before calling `StartListeningCore` - Subscribe to current value in `InpcPropertyAccessorPlugin` before sending current value, because we're unsubscribed when `SendCurrentValue` exits	6 years ago
Dariusz Komosiński	9acf82d47b	!B Fix expression nodes not knowing if last value is actually null or dead.	6 years ago
Dariusz Komosinski	868b5ea840	Update WeakReference usages to use the generic one.	7 years ago
Jeremy Koritzinsky	44bf2ee721	Add unit test and fix #2149 .	7 years ago
Andrey Kunchev	458d45bb49	fix problem in complex binging chain, when a null value in chain reset current value to all subsequent expression nodes, so next change is starting on clean	7 years ago
Steven Kirk	0c078c9dec	Don't use rx for ExpressionNodes. `ExpressionNode`s were always single-subscriber and making them use `IObservable<>` meant that we had to have extra allocations in order to return `IDisposable`s. Instead of using `IObservable` use a simpler `Subscribe`/`Unsubscribe` pattern. This saves a bunch more memory.	8 years ago
Jeremy Koritzinsky	af186e3529	Move string-based binding paths up to Avalonia.Markup. Make the LINQ Expression paths and raw ExpressionNodes (now public) the primarily supported syntax.	8 years ago
Jeremy Koritzinsky	1c3b714a0e	Move fix up to SettableNode and ExpressionNode so all settable node types (i.e. PropertyAccessor and Indexer nodes) can get the fix.	8 years ago
Jeremy Koritzinsky	cf8244b37a	Move current contents of Avalonia.Markup to Avalonia.Base. Move Avalonia.Markup.Xaml.Data/Parser classes to Avalonia.Markup since they're not Xaml-specific. Use pattern-matching switch. Fix bug from cleanup.	8 years ago
Steven Kirk	f4f0597dca	Update next node in binding chain on error. Fixes #831 and makes `Pushing_Null_To_RootObservable_Updates_Leaf_Node` test pass.	9 years ago
Steven Kirk	715149b1f5	Improve stream operator error message. When a stream operator is applied to an unsupported type.	9 years ago
Steven Kirk	0ddf4caa95	Added a "stream" binding expression operator. Which is now required when wanting to get the value produced by a Task/IObservable rather than the Task/IObservable itself. Fixes #711.	9 years ago
Steven Kirk	c2a14f9db7	Swapped names in ExpressionNode. Swapped names of StartListening and StartListeningCore - method names ending with Core should be the subclass implementation.	10 years ago
Steven Kirk	7cb001801a	Try to improve logged binding errors. - Don't log an error when the target for the root ExpressionNode is null. This is usually because the `DataContext` hasn't been set up yet and it spewed a load of useless error messages. - Add a Description field to `ExpressionObserver` that can be used in the case of e.g. #control bindings to record the whole expression (with the "#control" part) rather than just the part tracked by the `ExpressionObserver`.	10 years ago
Steven Kirk	f59c16bc00	Improve broken binding diagnostic messages.	10 years ago
Steven Kirk	0c2057e458	Fix failing tests, add other tests. Also use logical parent's DataContext as base for DataContext bindings instead of visual parent's. Was previously in error.	10 years ago
Steven Kirk	c5c60c483a	Add concept of "value plugins". These are used to extensibly handle special values like `Task` and `IObservable<>`. Previously this was baked into the expression observer architecture with a TODO comment saying that it needs to be extensible.	10 years ago
Steven Kirk	2f72295657	Started refactor of ExpressionObserver. Tying to be more "rx", but also will allow us to move forward on BindingNotification changes.	10 years ago
Steven Kirk	4906a472b0	Reimplemented data validation using BindingNotifications.	10 years ago
Steven Kirk	abdbcac79d	Added BindingNotification. This will replace BindingError and IValidationStatus for bindings that want to notify binding/validation errors. Still WIP.	10 years ago
Steven Kirk	5c33fbc6ee	Reimplemented property validation. As far as it was in `property-validation-grokys` branch. Things were messed up on master so had to merge this manually so may be problems.	10 years ago
Steven Kirk	5be41985c3	Renamed Perspex -> Avalonia	10 years ago
Jeremy Koritzinsky	287cc3c22e	Fixes failing tests for when an ExpressionSubject/ExpressionObserver is never subscribed to.	10 years ago
Jeremy Koritzinsky	aab4331a52	Changed validation on controls to allow notifications from multiple types of validation and correctly report if it is valid. Changed initalization of validation plugins to nest within each other so there can be multiple active at once.	10 years ago
Jeremy Koritzinsky	ee486113e5	Finished wiring up validation support. Now exceptions and INotifyDataErrorInfo implementers will set controls into their ":invalid" pseudo-class state.	10 years ago
Steven Kirk	886fbb5458	Make ExpressionObserver accept a priority for sets. This makes auto-expanding the treeview in DevTools work again.	10 years ago
Steven Kirk	3d271cd020	Started implementing weak bindings. Tests currently failing as WeakSubscriptionManager doesn't support unsubscribing yet.	10 years ago
Steven Kirk	67835cc09b	Applied a bunch of resharper suggestions.	10 years ago
Steven Kirk	7734f2bb52	Fix assorted bugs.	10 years ago
Steven Kirk	b230c3b3f3	Renamed XamlBinding -> Binding Had to also rename enclosing namespace from Binding to Data as classes with same name as a namespace cause problems.	10 years ago
Steven Kirk	43a66901fc	Remove ExpressionValue. Use PerspexProperty.UnsetValue instead.	10 years ago
Steven Kirk	d43a79fab5	Wrote binding expression parser by hand. Sprache couldn't cope with it as it requires a left-recursive grammar.	11 years ago
Steven Kirk	0f5af3db63	Use Sprache for parsing expressions. Use sprache instead of Roslyn for parsing expressions. One test still failing.	11 years ago
Steven Kirk	e3b6ce4186	Add support for indexers in binding expressions.	11 years ago
Steven Kirk	774a9c0911	Implemented binding negation.	11 years ago
Steven Kirk	962c1ea01b	Pass SetValue through expression chain.	11 years ago
Steven Kirk	772937ad15	Change ExpressionValue to struct. And add some docs.	11 years ago
Steven Kirk	cf3834755d	More ExpressionObserver tests.	11 years ago
Steven Kirk	005cd231cc	Initial implementation of ExpressionObserver.	11 years ago
