Terminal.Gui/UnitTests/Views/TextViewTests.cs
BDisp 325180ae48 Fixes #2680. Make the TextView API more extensible. (#2682) 
* Fixes #2680. Make the TextView API more extensible.

* Remove unnecessary using.

* Add GetLine method.

* Change RuneCell Attribute property to ColorScheme property.

* Add LoadRuneCells method and unit test.

* Add helper method to set all the Colors.ColorSchemes with the same attribute.

* Change RuneCell to class.

* Add IEquatable<RuneCell> interface.

* Fix unit test.

* Still fixing unit test.

* Fixes #2688. ReadOnly TextView's broken scrolling after version update.

* keyModifiers must be reset after key up was been processed.

* Trying fix server unit test error.

* Prevents throw an exception if RuneCell is null.

* Still trying fix this unit test.

* Cleaning code.

* Fix when the RuneCell is null.

* Fix throwing an exception if current column position is greater than the line length.

* Fixes #2689. Autocomplete doesn't popup after typing the first character.

* Fix Used on TextField.

* Always use the original ColorScheme if RuneCell.ColorScheme is null.

* Fix Used on TextView.

* Add RuneCellEventArgs and draw colors events.

* Add two more samples to the scenario.

* Fix a bug which was causing unit tests with ColorScheme fail.

* Fix a issue when WordWrap is true by always loading the old text.

* Improves debugging in RuneCell.

* WordWrap is now preserving the ColorScheme of the unwrapped lines.

* Simplifying unit test.

* Ensures the foreground and background colors are never the same if Used is false.

* Remove nullable from the parameter.

* Merge syntax highlighting of quotes and keywords together

* Add IdxRow property into the RuneCellEventArgs.

* Fix pos calculation on windows
(where newline in Text is \r\n not \n)

* Fix events not being cleared when toggling samples.

* Change Undo and Redo to a public method.

* Changes some methods names to be more explicit.

* Call OnContentsChanged on needed methods and fix some more bugs.

* Adds InheritsPreviousColorScheme to allow LoadRuneCells uses personalized color schemes.

* Serializes and deserializes RuneCell to a .rce extension file.

* Prevents throwing if column is bigger than the line.

* Avoids create a color attribute without one of the foreground or background values. In Linux using -1 throws an exception.

* Replace SetAllAttributesBasedOn method with a ColorScheme constructor.

* Move RuneCell string extensions to TextView.cs

* Reverted parameter name from cell to rune.

* Change Row to UnwrappedPosition which provide the real unwrapped text position within the Col.

* Add brackets to Undo and Redo methods.

* Replace all the LoadXXX with Load and rely on the param type to differentiate.

* Open a file inside a using.

* Proves that the events run twice for WordWrap disabled and the enabled.

* Remove GetColumns extension for RuneCell.

* Add braces to Undo an Redo.

* Change comment.

* Add braces.

* Delete remarks tag.

* Explaining used color and ProcessInheritsPreviousColorScheme.

* Fix comment.

* Created a RuneCellTests.cs file.

* Rename to StringToLinesOfRuneCells.

* Make ToRuneCells private.
