Updated type casting and pattern matching logic to reflect these changes. Removed the unused `_stopAfterFirstIteration` field from the `ApplicationImpl` class to clean up the codebase. * Increase minimum code coverage target to 75% Updated the `codecov.yml` configuration file to raise the `project.default.target` value from 70% to 75%, enforcing stricter code coverage requirements for the overall project. * Add comprehensive unit tests for ApplicationImpl Begin/End logic Added ApplicationImplBeginEndTests with 16 tests covering: - Begin/End argument validation - SessionStack push/pop operations - Current property management - Balanced Begin/End enforcement - Multiple nested Begin/End scenarios - ResetState cleanup behavior - Toplevel activation/deactivation - SessionToken management Tests validate the fragile state management logic in ApplicationImpl.Lifecycle.cs and ApplicationImpl.Run.cs to catch regressions in Current/SessionStack handling. Co-authored-by: tig <585482+tig@users.noreply.github.com> * Refactor ApplicationImplBeginEndTests to work with ApplicationImpl instances directly Tests now: - Create ApplicationImpl instances directly instead of using global Application - Use try-finally blocks to ensure Shutdown() is always called - Work with app.Init() and app.Shutdown() properly - 13 of 16 tests passing (3 tests need adjustment for ResetState behavior) Tests validate fragile Begin/End state management logic without polluting global Application state. Co-authored-by: tig <585482+tig@users.noreply.github.com> * Fix ApplicationImplBeginEndTests: Remove explicit ResetState calls, rely on Shutdown Per maintainer feedback: - Tests should not call ResetState explicitly if they call Shutdown (Shutdown calls ResetState) - Removed all explicit app.ResetState() calls from tests - Tests now only call Shutdown in finally blocks for cleanup - Ensured toplevels are disposed BEFORE Shutdown to satisfy DEBUG_IDISPOSABLE assertions - Fixed test cleanup order to prevent ResetState assertion failures - All 16 tests now pass successfully ResetState is idempotent - the issue was tests calling it unnecessarily and with incorrect disposal ordering. Co-authored-by: tig <585482+tig@users.noreply.github.com> * Phase 1: Enable nullable by default, add directives to all files - Added enable to Terminal.Gui.csproj - Removed #nullable enable from 37 files (now redundant with project setting) - Added #nullable disable to 170 files that don't have nullable enabled yet - Build successful with 279 nullable warnings (expected) Breakdown of files with #nullable disable: - 27 in Views/ directory (will remain disabled per plan) - 143 outside Views/ (need to be fixed in subsequent commits) Next: Systematically fix nullable issues in non-View files. Co-authored-by: tig <585482+tig@users.noreply.github.com> * Phase 2: Remove nullable disable from all non-View files - COMPLETE! - Removed #nullable disable from 142 non-View files - All non-View code is now nullable-enabled - Build successful with 0 errors, only 1 unrelated warning - Created NULLABLE_VIEWS_REMAINING.md documenting the 121 View files still with nullable disable Nullable cleanup summary: ✅ App/: 25 files - nullable enabled ✅ Configuration/: 24 files - nullable enabled ✅ ViewBase/: 30 files - nullable enabled ✅ Drivers/: 25 files - nullable enabled ✅ Drawing/: 18 files - nullable enabled ✅ FileServices/: 7 files - nullable enabled ✅ Input/: 6 files - nullable enabled ✅ Text/: 5 files - nullable enabled ✅ Resources/: 3 files - nullable enabled ⏸️ Views/: 121 files - remain disabled (as requested) Total: 143 files nullable-enabled, 121 View files remain disabled. Co-authored-by: tig <585482+tig@users.noreply.github.com> * WIP: fixing nullability issues. * Fixed final nullability issues. * Moved Arrangment tests * Refactor and improve modularity across multiple classes Refactored `FillRectangles` in `RegionScenario` and `Region` to accept an `IDriver` parameter, reducing reliance on global state. Updated `ApplicationImpl` to replace static method calls with instance methods for better encapsulation. Renamed `Toplevel` to `Current` in `IPopover` and related classes for clarity. Simplified `LineCanvas` methods by removing unnecessary `IDriver` parameters. Added `Id` and `App` properties to `View` for better state management and unique identification. Streamlined the `Driver` property in `View` with a concise getter. Improved formatting and consistency across files, including `Region` and `IntersectionRuneResolver`. Enhanced thread safety in `Region` and cleaned up redundant code. Updated tests to align with interface changes and ensure compatibility. * Refactor to make IDriver dependency explicit Updated `AnsiEscapeSequenceRequest.Send` to accept an `IDriver?` parameter, replacing reliance on `Application.Driver`. Refactored `AnsiRequestScheduler` methods (`SendOrSchedule`, `RunSchedule`, and private `Send`) to propagate the `IDriver?` parameter, ensuring explicit driver dependency. Modified `DriverImpl.QueueAnsiRequest` to pass `this` to `SendOrSchedule`. Updated `AnsiRequestSchedulerTests` to reflect new method signatures, passing `null` for the driver parameter where applicable. Added `` documentation for new parameters to improve clarity. These changes enhance flexibility, maintainability, and testability by reducing reliance on global state and allowing driver substitution in tests. * WIP: Started migrating to View.App Refactored `ApplicationImpl` to ensure proper handling of the `App` property for `Toplevel` instances, improving modularity. Replaced direct references to `Application` with `App` in `Border`, `ShadowView`, and other classes to enhance flexibility and maintainability. Introduced `GetApp` in `View` to allow overrides for retrieving the `App` instance. Updated `Adornment` to use this method. Moved mouse event subscriptions in `Border` to `BeginInit` for proper lifecycle management. Updated unit tests in `ArrangementTests` to use `App.Mouse` instead of `Application.Mouse`, ensuring alignment with the refactored design. Added `BeginInit` and `EndInit` calls for proper initialization during tests. Removed redundant code and improved test assertions. * WIP: Next set of View.App changes Updated `SetClipToScreen`, `SetClip`, and `GetClip` methods to accept an `IDriver` parameter, replacing reliance on the global `Application.Driver`. This improves modularity, testability, and reduces implicit global state usage. - Updated `Driver` property in `View` to use `App?.Driver` as fallback. - Refactored `DimAuto` to use `App?.Screen.Size` with a default for unit tests. - Updated all test cases to align with the new method signatures. - Performed general cleanup for consistency and readability. * Adds View clip tests. * Merged * Merged * wip * Fixed test bug. * Refactored Thickness.Draw to require driver. * Made TextFormatter.Draw require driver. * Code cleanup. * Un did stoopid idea. * Decouped Application.Navigation * MASSIVE - Almost completely decoupled Application from View etc... * Obsolete * Missed some * More cleanup and decoupling. Refactor `ToString` and remove legacy code Refactored `ToString` implementations across `Application`, `DriverImpl`, and `IDriver` to improve consistency and maintainability. Removed the legacy `ToString(IDriver? driver)` method and its associated references. Simplified `ToString` in `DriverImpl` to generate a string representation of the `Contents` buffer. Replaced redundant XML documentation with `` tags to reduce duplication. Cleaned up unused `global using` directives and removed deprecated methods and properties, including `Screen`, `SetCursorVisibility`, and `IsRuneSupported`. Updated test cases in `GuiTestContext` and `DriverAssert` to use the new `ToString` implementation. Improved error messages for better debugging output. Streamlined LINQ queries and removed redundant checks for better readability and performance. Enhanced maintainability by decluttering the codebase, aligning namespaces, and consolidating related changes. * Changes before error encountered Co-authored-by: tig <585482+tig@users.noreply.github.com> * Update docfx/docs to document View.App architecture and instance-based patterns Updated 16 documentation files to reflect the major architectural changes: NEW FILES: - application.md: Comprehensive deep dive on decoupled Application architecture UPDATED FILES: - View.md: Documents View.App property, GetApp(), and instance-based patterns - navigation.md: Shows View.App usage instead of static Application - drivers.md: Documents View.Driver and GetDriver() patterns - keyboard.md: Event handling through View.App - mouse.md: Mouse event handling via View.App - arrangement.md: Updated code examples to use View.App - drawing.md: Rendering examples with instance-based API - cursor.md: Cursor management through View.App - multitasking.md: SessionStack and session management via View.App - Popovers.md: Popover patterns with View.App - cancellable-work-pattern.md: Updated examples - command.md: Command pattern with View.App context - config.md: Configuration access through View.App - migratingfromv1.md: Migration guide for static→instance patterns - newinv2.md: Documents new instance-based architecture All code examples now demonstrate the instance-based API (view.App.Current) instead of obsolete static Application references. Documentation accurately reflects the massive architectural decoupling achieved in this PR. Co-authored-by: tig <585482+tig@users.noreply.github.com> * Add `ToAnsi` support for ANSI escape sequence generation Introduced `ToAnsi` in `IDriver` and `IOutput` interfaces to generate ANSI escape sequences representing the terminal's current state. This enables serialization of terminal content for debugging, testing, and exporting. Implemented `ToAnsi` in `DriverImpl` and `FakeOutput`, supporting both 16-color and RGB modes. Refactored `OutputBase` with helper methods `BuildAnsiForRegion` and `AppendCellAnsi` for efficient ANSI generation. Enhanced `GuiTestContext` with `AnsiScreenShot` for capturing terminal state during tests. Added `ToAnsiTests` for comprehensive validation, including edge cases, performance, and wide/Unicode character handling. Updated documentation to reflect `ToAnsi` functionality and modernized driver architecture. Improved testability, modularity, and performance while removing legacy driver references. * Improve null safety and cleanup in GuiTestContext Enhanced null safety across `GuiTestContext` and `GuiTestContextTests`: - Replaced `a` with `app` for better readability in tests. - Added null checks (`!`, `?.`) to prevent potential null reference exceptions. - Removed redundant `WaitIteration` and duplicate `ScreenShot` calls. Improved error handling and robustness: - Updated shutdown logic to use null-safe calls for `RequestStop` and `Shutdown`. - Applied null-safe invocation for `_applicationImpl.Invoke`. General cleanup: - Removed redundant method calls and improved naming consistency. - Ensured better maintainability and adherence to best practices. * Refactor docs: remove deprecated files, update architecture Removed outdated documentation files related to the terminology proposal (`terminology-before-after.md`, `terminology-diagrams.md`, `terminology-index.md`, `terminology-proposal-summary.md`, `terminology-proposal.md`) from the `Docs` project. These files were either deprecated or consolidated into other documentation. Updated `application.md`: - Added a "View Hierarchy and Run Stack" section with a Mermaid diagram to illustrate the relationship between the view hierarchy and the application session stack. - Added a "Usage Example Flow" section with a sequence diagram to demonstrate the flow of running and stopping views. These changes improve clarity, streamline documentation, and align with the finalized terminology updates for the `Application.Current` and `Application.SessionStack` APIs. * Refactor Init/Run methods to simplify driver handling The `Init` method in `Application` and `IApplication` now accepts only an optional `driverName` parameter, removing the `IDriver` parameter. This simplifies initialization by relying on driver names to determine the appropriate driver. The `Run` methods have been updated to use `driverName` instead of `driver`, ensuring consistency with the updated `Init` method. Replaced redundant inline documentation with `` tags to improve maintainability and consistency. Legacy `Application` methods (`Init`, `Shutdown`, `Run`) have been marked as `[Obsolete]` to signal their eventual deprecation. Test cases have been refactored to align with the updated `Init` method signature, removing unused `driver` parameters. Documentation files have also been updated to reflect these API changes. These changes improve clarity, reduce complexity, and ensure a more consistent API design. * Refactor: Introduce Application.Create() factory method Introduced a new static method `Application.Create()` to create instances of `IApplication`, replacing direct instantiation of `ApplicationImpl`. This enforces a cleaner, recommended pattern for creating application instances. Made the `ApplicationImpl` constructor `internal` to ensure `Application.Create()` is used for instance creation. Refactored test cases across multiple files to use `Application.Create()` instead of directly instantiating `ApplicationImpl`. Simplified object initialization in tests using target-typed `new()` expressions. Updated documentation and examples in `application.md` to reflect the new instance-based architecture and highlight its benefits, such as supporting multiple applications with different drivers. Improved code readability, formatting, and consistency in tests and documentation. Aligned `ApplicationImplBeginEndTests` to use `IApplication` directly, adhering to the new architecture. * Added `Application.StopAll` and fixed coupling issues. Refactored `ApplicationImpl` to use an instance-based approach, replacing the static singleton pattern and Lazy. Introduced `SetInstance` for configuring the singleton instance and updated tests to use `ApplicationImpl.Instance` or explicitly set the `Driver` property. Enabled nullable reference types across the codebase, updating fields and variables to nullable types where applicable. Added null checks to improve safety and prevent runtime errors. Refactored timeout management by introducing tokens for `Application.AddTimeout` and adding a `StopAll` method to `TimedEvents` for cleanup. Updated tests to use `System.Threading.Timer` for independent watchdog timers. Removed legacy code, improved logging for error cases, and updated view initialization to explicitly set `App` or `Driver` in tests. Enhanced test coverage and restructured `ScrollSliderTests` for better readability. Performed general code cleanup, including formatting changes, removal of unused imports, and improved naming consistency. * Refactor: Transition to IApplication interface Refactored the codebase to replace the static `Application` class with the `IApplication` interface, improving modularity, testability, and maintainability. Updated methods like `Application.Run`, `RequestStop`, and `Init` to use the new interface. Marked static members `SessionStack` and `Current` as `[Obsolete]` and delegated their functionality to `ApplicationImpl.Instance`. Updated XML documentation to reflect these changes. Simplified code by removing redundant comments, unused code, and converting methods like `GetMarginThickness` to single-line expressions. Improved null safety with null-conditional operators in `ToplevelTransitionManager`. Enhanced consistency with formatting updates, logging improvements, and better error handling. Updated `Shortcut` and other classes to align with the new interface-based design. Made breaking changes, including the removal of the `helpText` parameter in the `Shortcut` constructor. Updated `Wizard`, `Dialog`, and `GraphView` to use `IApplication` methods. Adjusted `ViewportSettings` and `HighlightStates` for better behavior. * Enhance null-safety and simplify codebase Improved null-safety by adopting nullable reference types and adding null-forgiving operators (`!`) where appropriate. Replaced direct method calls with null-safe calls using the null-conditional operator (`?.`) to prevent potential `NullReferenceException`. Removed default parameter values in test methods to enforce explicit parameter passing. Refactored test classes to remove unnecessary dependencies on `ITestOutputHelper`. Fixed a bug in `WindowsOutput.cs` by setting `_force16Colors` to `false` to avoid reliance on a problematic driver property. Updated `SessionTokenTests` to use null-forgiving operators for clarity in intentional null usage. Simplified graph and UI updates by ensuring safe access to properties and methods. Cleaned up namespaces and removed unused `using` directives for better readability. Updated `Dispose` methods to use null-safe calls and replaced nullable driver initialization with non-nullable initialization in `ScrollSliderTests` to ensure proper instantiation. * Refactor test code to use nullable `App` property Replaced direct `Application` references with `App` property across test classes to improve encapsulation and robustness. Updated `GuiTestContext` to use a nullable `App` property, replacing `_applicationImpl` for consistency. Refactored key event handling to use `App.Driver` and revised `InitializeApplication` and `CleanupApplication` methods to ensure safe usage of the nullable `App` property. Updated `Then` callbacks to explicitly pass `App` for clarity. Replaced `Application.QuitKey` with `context.App?.Keyboard.RaiseKeyDownEvent` to ensure context-specific event handling. Refactored `EnableForDesign` logic in `MenuBarv2Tests` and `PopoverMenuTests` to operate on the correct application instance. Improved null safety in test assertions and revised `RequestStop` and `Shutdown` calls to use `App?.RequestStop` and `App?.Shutdown`. Updated navigation logic to use `Terminal.Gui.App.Application` for namespace consistency. Enhanced exception handling in the `Invoke` method and performed general cleanup to align with modern C# practices, improving maintainability and readability. * Commented out exception handling in Application.Shutdown The `try-catch` block around `Application.Shutdown` was commented out, disabling the logging of exceptions thrown after a test exited. This change removes the `catch` block that used `Debug.WriteLine` for logging. The `finally` block remains intact, ensuring cleanup operations such as clearing `View.Instances` and resetting the application state are still executed. * Fixes #4394 - Changing Theme at Runtime does not Update Some Properties * Tweaks to config format. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: Tig Co-authored-by: tig

Added `EnsureSelectedItemVisible` to maintain visibility of the selected item. Updated `IListDataSource` with detailed XML documentation and added `SuspendCollectionChangedEvent` for bulk updates.

Modernized the codebase with C# features like expression-bodied members and pattern matching. Fixed bugs related to `SelectedItem` validation and rendering artifacts. * Improve index validation in ComboBox and ListView Enhance robustness by adding stricter checks for valid indices in ComboBox and ListView. Updated conditions in the `_listview.SelectedItemChanged` event handler to ensure `e.Item` is non-negative before accessing `_searchSet`. Modified the `SetValue` method to use `e.Item` instead of `_listview.SelectedItem`. In ListView, updated the `OnSelectedChanged` method to validate that `SelectedItem` is non-negative (`>= 0`) before accessing the `Source` list. These changes prevent potential out-of-range errors and improve code safety. * Refactor and enhance test coverage across modules Refactored and added new tests to improve coverage, readability, and consistency across multiple test files. Key changes include: - **ShortcutTests.cs**: Added tests for `BindKeyToApplication` and removed redundant tests. - **SourcesManagerTests.cs**: Renamed `Update_*` tests to `Load_*` for clarity. - **ArrangementTests.cs**: Reintroduced `MouseGrabHandler` tests, added `ViewArrangement` flag tests, and improved structure. - **NeedsDrawTests.cs**: Replaced `Application.Screen.Size` with fixed dimensions for better isolation. - **DimAutoTests.cs**: Updated layout tests to use fixed dimensions. - **FrameTests.cs**: Standardized object initialization and validated frame behavior. - **SubViewTests.cs**: Improved formatting and modernized event handling. - **NumericUpDownTests.cs**: Decoupled layout tests from screen size. General improvements: - Enhanced formatting and removed redundant tests. - Added comments for clarity. - Introduced `ITestOutputHelper` for better debugging in `ArrangementTests`. * Refactor to use nullable types for better null safety Enabled nullable reference types across the codebase to improve null safety and prevent potential null reference issues. Refactored `SelectedItem` and related properties from `int` to `int?` to represent no selection with `null` instead of `-1`. Updated logic, event arguments, and method signatures to handle nullable values consistently. Simplified object initialization using modern C# syntax and improved code readability with interpolated strings. Added null checks and early returns to prevent runtime errors. Enhanced error handling by throwing `ArgumentOutOfRangeException` for invalid values. Updated tests to reflect the changes, replacing assertions for `-1` with `null` and ensuring proper handling of nullable values. Cleaned up redundant code and improved formatting for better maintainability. * on` functionality has been deprecated, refactored, or removed from the `Shortcut` class. * Refactor: Transition to instance-based architecture Updated `Run-LocalCoverage.ps1` to increase `--blame-hang-timeout` from 10s to 60s. Improved null safety in `GuiTestContext` by adding null-conditional operators. Commented out problematic code in `SetupFakeApplicationAttribute.cs` to prevent test hangs. Excluded `ViewBase` files from `UnitTests.Parallelizable.csproj` and removed redundant folder declarations. Simplified event handling in `IListDataSourceTests.cs` and updated `ListViewTests.cs` to use nullable reference types. Enhanced documentation to emphasize the transition to an instance-based application architecture. Updated examples in `application.md`, `multitasking.md`, and `navigation.md` to reflect the use of `Application.Create()` and `View.App`. Clarified the obsolescence of the static `Application` class. Revised table of contents in `toc.yml` to include new sections like "Application Deep Dive" and "Scheme Deep Dive." Added `dotnet-tools.json` for tool configuration. These changes improve maintainability, testability, and alignment with modern C# practices. * Refactor ListViewTests to use Terminal.Gui framework The `ListViewTests` class has been refactored to replace the `AutoInitShutdown` attribute with explicit application lifecycle management using `IApplication` and `app.Init()` from the `Terminal.Gui` framework. Key changes include: - Rewriting tests to use `Terminal.Gui`'s application lifecycle. - Adding a private `_output` field for logging test output via `ITestOutputHelper`. - Updating `DriverAssert.AssertDriverContentsWithFrameAre` to include `app.Driver` for UI verification. - Rewriting tests like `Clicking_On_Border_Is_Ignored`, `EnsureSelectedItemVisible_SelectedItem`, and others to align with the new framework. - Adding explicit calls to `app.Shutdown()` for proper cleanup. - Enabling nullable reference types with `#nullable enable`. - Updating `using` directives and `namespace` to reflect the new structure. These changes improve test maintainability, compatibility, and diagnostics. * Update Terminal.Gui/Views/CollectionNavigation/CollectionNavigatorBase.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Terminal.Gui/Views/CollectionNavigation/CollectionNavigatorBase.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Examples/UICatalog/UICatalogTop.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Terminal.Gui/Views/ListWrapper.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Terminal.Gui/Views/ListWrapper.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Updated the `SetMark` method to return `Source.IsMarked(SelectedItem.Value)` for consistency and removed an outdated comment questioning its correctness. Enhanced the exception message in the `SelectedItem` property setter to provide clearer guidance when the value is out of range. * Add comprehensive ListView behavior test coverage Added multiple test methods to validate `ListView` behavior: - `Vertical_ScrollBar_Hides_And_Shows_As_Needed`: Ensures the vertical scrollbar auto-hides/shows based on content height. - `Mouse_Wheel_Scrolls`: Verifies vertical scrolling with the mouse wheel updates `TopItem`. - `SelectedItem_With_Source_Null_Does_Nothing`: Confirms no exceptions occur when setting `SelectedItem` with a `null` source. - `Horizontal_Scroll`: Tests horizontal scrolling, including programmatic and mouse wheel interactions, ensuring `LeftItem` updates correctly. - `SetSourceAsync_SetsSource`: Validates the asynchronous `SetSourceAsync` method updates the source and item count. - `AllowsMultipleSelection_Set_To_False_Unmarks_All_But_Selected`: Ensures disabling multiple selection unmarks all but the selected item. - `Source_CollectionChanged_Remove`: Confirms `SelectedItem` and source count update correctly when items are removed from the source collection. --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --- .config/dotnet-tools.json | 5 + .../UICatalog/Scenarios/AllViewsTester.cs | 2 +- .../UICatalog/Scenarios/ComboBoxIteration.cs | 4 +- .../UICatalog/Scenarios/DynamicMenuBar.cs | 24 +- .../UICatalog/Scenarios/DynamicStatusBar.cs | 29 +- .../Scenarios/ListViewWithSelection.cs | 8 +- .../UICatalog/Scenarios/ListsAndCombos.cs | 2 +- Examples/UICatalog/Scenarios/SpinnerStyles.cs | 2 +- Examples/UICatalog/UICatalogTop.cs | 14 +- Scripts/Run-LocalCoverage.ps1 | 2 +- .../CollectionNavigatorBase.cs | 74 +- .../ICollectionNavigator.cs | 8 +- Terminal.Gui/Views/ComboBox.cs | 27 +- Terminal.Gui/Views/IListDataSource.cs | 107 +- Terminal.Gui/Views/ListView.cs | 1451 +++++++-------- Terminal.Gui/Views/ListViewEventArgs.cs | 9 +- Terminal.Gui/Views/ListWrapper.cs | 256 +++ Terminal.Gui/Views/TableView/TableView.cs | 6 +- Terminal.Gui/Views/Toplevel.cs | 2 +- Terminal.sln.DotSettings | 1 + .../UICatalog/ScenarioTests.cs | 4 +- .../GuiTestContext.ContextMenu.cs | 2 +- .../GuiTestContext.ViewBase.cs | 4 +- .../SetupFakeApplicationAttribute.cs | 5 +- Tests/UnitTests/Views/ListViewTests.cs | 1225 ------------- .../Configuration/SourcesManagerTests.cs | 22 +- .../Text/CollectionNavigatorTests.cs | 30 +- .../UnitTests.Parallelizable.csproj | 8 +- .../View/Draw/NeedsDrawTests.cs | 10 +- .../View/Layout/Dim.AutoTests.PosTypes.cs | 2 +- .../View/Layout/Dim.AutoTests.cs | 14 +- .../View/Layout/FrameTests.cs | 10 +- .../View/SubviewTests.cs | 12 +- .../Views/IListDataSourceTests.cs | 513 ++++++ .../Views/ListViewTests.cs | 1556 ++++++++++++++++- .../Views/NumericUpDownTests.cs | 10 +- docfx/docs/application.md | 56 +- docfx/docs/config.md | 3 +- docfx/docs/index.md | 8 + docfx/docs/migratingfromv1.md | 68 + docfx/docs/multitasking.md | 56 +- docfx/docs/navigation.md | 15 +- docfx/docs/newinv2.md | 41 + docfx/docs/toc.yml | 20 +- 44 files changed, 3372 insertions(+), 2355 deletions(-) create mode 100644 .config/dotnet-tools.json create mode 100644 Terminal.Gui/Views/ListWrapper.cs delete mode 100644 Tests/UnitTests/Views/ListViewTests.cs create mode 100644 Tests/UnitTestsParallelizable/Views/IListDataSourceTests.cs diff --git a/.config/dotnet-tools.json b/.config/dotnet-tools.json new file mode 100644 index 000000000..b0e38abda --- /dev/null +++ b/.config/dotnet-tools.json @@ -0,0 +1,5 @@ +{ + "version": 1, + "isRoot": true, + "tools": {} +} \ No newline at end of file diff --git a/Examples/UICatalog/Scenarios/AllViewsTester.cs b/Examples/UICatalog/Scenarios/AllViewsTester.cs index 2f6e9e016..5ac97bea9 100644 --- a/Examples/UICatalog/Scenarios/AllViewsTester.cs +++ b/Examples/UICatalog/Scenarios/AllViewsTester.cs @@ -65,7 +65,7 @@ public class AllViewsTester : Scenario // Dispose existing current View, if any DisposeCurrentView ();

charset=UTF-8 Content-Transfer-Encoding: 8bit * Add comprehensive unit tests for WindowsKeyConverter - Implement 118 parallelizable unit tests for WindowsKeyConverter - Cover ToKey and ToKeyInfo methods with full bidirectional testing - Test basic characters, modifiers, special keys, function keys - Test VK_PACKET Unicode/IME input - Test OEM keys, NumPad keys, and lock states - Include round-trip conversion tests - All tests passing successfully Fixes #4389 * Add test documenting VK_PACKET surrogate pair limitation VK_PACKET sends surrogate pairs (e.g., emoji) as two separate events. Current WindowsKeyConverter processes each independently without combining. Test documents this limitation for future fix at InputProcessor level. * Mark WindowsKeyConverterTests as Windows-only Tests now skip on non-Windows platforms using SkipException in constructor. This prevents CI failures on macOS and Linux where Windows Console API is not available. * Properly mark WindowsKeyConverter tests as Windows-only Created custom xUnit attributes SkipOnNonWindowsFact and SkipOnNonWindowsTheory that automatically skip tests on non-Windows platforms. This prevents CI failures on macOS and Linux. * Refactor and enhance test coverage for input processors Refactored `ApplicationImpl.cs` to simplify its structure by removing the `_stopAfterFirstIteration` field. Reintroduced and modernized test files with improved structure and coverage: - `NetInputProcessorTests.cs`: Added tests for `ConsoleKeyInfo` to `Rune`/`Key` conversion and queue processing. - `WindowSizeMonitorTests.cs`: Added tests for size change event handling. - `WindowsInputProcessorTests.cs`: Added tests for keyboard and mouse input processing, including mouse flag mapping. - `WindowsKeyConverterTests.cs`: Added comprehensive tests for `InputRecord` to `Key` conversion, covering OEM keys, modifiers, Unicode, and round-trip integrity. Improved test coverage for edge cases, introduced parameterized tests, and documented known limitations for future improvements. * Use Trait-based platform filtering for WindowsKeyConverter tests Added [Trait('Platform', 'Windows')] and [Collection('Global Test Setup')] attributes. Tests will run on Windows but can be filtered in CI on other platforms using --filter 'Platform!=Windows' if needed. This approach doesn't interfere with GlobalTestSetup and works correctly with xUnit. * Filter Windows-specific tests on non-Windows CI platforms Added --filter 'Platform!=Windows' for Linux and macOS runners to exclude WindowsKeyConverterTests which require Windows Console APIs. Windows runner runs all tests normally. * Fix log path typo and remove Codecov upload step Corrected a typo in the log directory path from `logs/UnitTestsParallelable/` to `logs/UnitTestsParallelizable/`. Removed the "Upload Parallelizable UnitTests Coverage to Codecov" step, which was conditional on `matrix.os == 'ubuntu-latest'` and used the `codecov/codecov-action@v4` action. This change improves log handling and removes the Codecov integration. * Refactor application reset logic Replaced `Application.ResetState(true)` with a more explicit reset mechanism. Introduced `ApplicationImpl.SetInstance(null)` to clear the application instance and added `CM.Disable(true)` to disable specific components. This change improves control over the reset process and ensures a more granular approach to application state management. * Improve null safety with ?. and ! operators Enhanced null safety across the codebase by introducing the null-conditional operator (`?.`) and null-forgiving operator (`!`) where appropriate. - Updated `app` and `driver` method calls to use `?.` to prevent potential `NullReferenceException` errors. - Added `!` to assert non-nullability in cases like `e.Value!.ToString()` and `app.Driver?.Contents!`. - Modified `lv.SelectedItemChanged` event handler to ensure safe handling of nullable values. - Updated `app.Shutdown()`, `app.LayoutAndDraw()`, and mouse event handling to use `?.`. - Ensured `driver.SetScreenSize` is invoked only when `driver` is not null. - Improved string concatenation logic with null-forgiving operator for `Contents`. - General improvements to null safety to make the code more robust and resilient to null references. * Improve Unicode tests and clarify surrogate pair handling Updated `WindowsKeyConverterTests` to enhance readability, improve test data, and clarify comments. Key changes include: - Reformatted `[Collection]` and `[Trait]` attributes for consistency. - Replaced placeholder Unicode characters with meaningful examples: - Chinese: `中`, Japanese: `日`, Korean: `한`, Accented: `é`, Euro: `€`, Greek: `Ω`. - Updated comments to replace placeholder emojis (`??`) with `😀` (U+1F600) for clarity. - Adjusted surrogate pair test data to accurately reflect `😀`. - Improved documentation of current limitations and future fixes for surrogate pair handling. These changes ensure more accurate and meaningful test cases while improving code clarity. * Ensure platform-specific test execution on Windows Added `System.Runtime.InteropServices` and `Xunit.Sdk` namespaces to `WindowsKeyConverterTests.cs` to support platform checks and test setup. Marked the test class with `[Collection("Global Test Setup")]` to enable shared test setup. Updated the `ToKey_NumPadKeys_ReturnsExpectedKeyCode` method to include a platform check, ensuring the test only runs on Windows platforms. * Integrate TrueColor support into ColorPicker Merged TrueColors functionality into ColorPicker, enhancing the scenario with TrueColor demonstration and gradient features. Updated `ColorPicker.cs` to include driver information, TrueColor support indicators, and a toggle for `Force16Colors`. Removed `TrueColors.cs` as its functionality is now consolidated. Refined `ColorBar` to use dynamic height with `Dim.Auto` for better flexibility. Added documentation to `HueBar` to clarify its role in representing the Hue component in HSL color space. * Revert workflow change. * Reverted attribute that didn't actualy work. --- Examples/UICatalog/Scenarios/ColorPicker.cs | 29 +- Examples/UICatalog/Scenarios/TrueColors.cs | 157 ---- Terminal.Gui/App/ApplicationImpl.Lifecycle.cs | 6 - Terminal.Gui/Views/Color/ColorBar.cs | 2 +- Terminal.Gui/Views/Color/HueBar.cs | 5 +- .../UICatalog/ScenarioTests.cs | 4 +- .../{ => Dotnet}/NetInputProcessorTests.cs | 0 .../{ => Windows}/WindowSizeMonitorTests.cs | 0 .../WindowsInputProcessorTests.cs | 0 .../Windows/WindowsKeyConverterTests.cs | 798 ++++++++++++++++++ .../Views/ListViewTests.cs | 30 +- 11 files changed, 848 insertions(+), 183 deletions(-) delete mode 100644 Examples/UICatalog/Scenarios/TrueColors.cs rename Tests/UnitTestsParallelizable/Drivers/{ => Dotnet}/NetInputProcessorTests.cs (100%) rename Tests/UnitTestsParallelizable/Drivers/{ => Windows}/WindowSizeMonitorTests.cs (100%) rename Tests/UnitTestsParallelizable/Drivers/{ => Windows}/WindowsInputProcessorTests.cs (100%) create mode 100644 Tests/UnitTestsParallelizable/Drivers/Windows/WindowsKeyConverterTests.cs diff --git a/Examples/UICatalog/Scenarios/ColorPicker.cs b/Examples/UICatalog/Scenarios/ColorPicker.cs index 61b71d093..69ae48660 100644 --- a/Examples/UICatalog/Scenarios/ColorPicker.cs +++ b/Examples/UICatalog/Scenarios/ColorPicker.cs @@ -3,7 +3,7 @@ using System.Collections.Generic; namespace UICatalog.Scenarios; -[ScenarioMetadata ("ColorPicker", "Color Picker.")] +[ScenarioMetadata ("ColorPicker", "Color Picker and TrueColor demonstration.")] [ScenarioCategory ("Colors")] [ScenarioCategory ("Controls")] public class ColorPickers : Scenario @@ -220,6 +220,33 @@ public class ColorPickers : Scenario }; app.Add (cbShowName); + var lblDriverName = new Label + { + Y = Pos.Bottom (cbShowName) + 1, Text = $"Driver is `{Application.Driver?.GetName ()}`:" + }; + bool canTrueColor = Application.Driver?.SupportsTrueColor ?? false; + + var cbSupportsTrueColor = new CheckBox + { + X = Pos.Right (lblDriverName) + 1, + Y = Pos.Top (lblDriverName), + CheckedState = canTrueColor ?

StringExtensions.GetColumns method should only return the total text width and not the sum of all runes width * Trying to fix unit test error * Update StringExtensions.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Resolving merge conflicts * Prevents Runes throwing if Grapheme is null * Add unit test to prove that null and empty string doesn't not throws anything. * Fix unit test failure * Fix IsValidLocation for wide graphemes * Add more combining * Prevent set invalid graphemes * Fix unit tests * Grapheme doesn't support invalid code points like lone surrogates * Fixes more unit tests * Fix unit test * Seems all test are fixed now * Adjust CharMap scenario with graphemes * Upgrade Wcwidth to version 4.0.0 * Reformat * Trying fix CheckDefaultState assertion * Revert "Trying fix CheckDefaultState assertion" This reverts commit c9b46b796ad206f2dd310fa680163b9f7de878f2. * Forgot to include driver.End in the test * Reapply "Trying fix CheckDefaultState assertion" This reverts commit 1060ac9b632c109dee785fa83057959575875ca2. * Remove ToString * Fix merge errors * Change to conditional expression * Assertion to prove that no exception throws during cell initialization. * Remove unnecessary assignment * Remove assignment to end * Replace string concatenation with 'StringBuilder'. * Replace more string concatenation with 'StringBuilder' * Remove redundant call to 'ToString' because Rune cast to a String object. * Replace foreach loop with Sum linq --------- Co-authored-by: Tig Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --- Directory.Packages.props | 2 +- .../UICatalog/Scenarios/CombiningMarks.cs | 15 +- Examples/UICatalog/Scenarios/LineDrawing.cs | 2 +- Examples/UICatalog/Scenarios/Sliders.cs | 16 +- .../UICatalog/Scenarios/SyntaxHighlighting.cs | 11 +- Terminal.Gui/Drawing/Cell.cs | 166 +- Terminal.Gui/Drawing/GraphemeHelper.cs | 49 + Terminal.Gui/Drawing/LineCanvas/LineCanvas.cs | 9 +- Terminal.Gui/Drivers/DriverImpl.cs | 30 +- Terminal.Gui/Drivers/IDriver.cs | 6 +- Terminal.Gui/Drivers/IOutputBuffer.cs | 8 +- Terminal.Gui/Drivers/OutputBase.cs | 33 +- Terminal.Gui/Drivers/OutputBufferImpl.cs | 308 +-- Terminal.Gui/Text/StringExtensions.cs | 88 +- Terminal.Gui/Text/TextFormatter.cs | 328 +-- Terminal.Gui/ViewBase/Adornment/ShadowView.cs | 8 +- .../ViewBase/View.Drawing.Primitives.cs | 20 +- Terminal.Gui/ViewBase/View.Drawing.cs | 14 +- .../AutocompleteFilepathContext.cs | 26 +- .../Autocomplete/ISuggestionGenerator.cs | 4 +- .../Views/Autocomplete/PopupAutocomplete.cs | 2 +- .../SingleWordSuggestionGenerator.cs | 16 +- Terminal.Gui/Views/CharMap/CharMap.cs | 79 +- Terminal.Gui/Views/Slider/Slider.cs | 50 +- .../Views/TableView/TreeTableSource.cs | 8 +- Terminal.Gui/Views/TextInput/TextField.cs | 34 +- Terminal.Gui/Views/TextInput/TextModel.cs | 110 +- Terminal.Gui/Views/TextInput/TextView.cs | 55 +- Terminal.Gui/Views/TreeView/Branch.cs | 42 +- Tests/UnitTests/DriverAssert.cs | 31 +- Tests/UnitTests/Drivers/ClipRegionTests.cs | 16 +- Tests/UnitTests/View/Draw/ClipTests.cs | 10 +- Tests/UnitTests/View/Draw/DrawTests.cs | 18 +- Tests/UnitTests/View/TextTests.cs | 9 +- Tests/UnitTests/Views/LabelTests.cs | 14 +- Tests/UnitTests/Views/ProgressBarTests.cs | 2352 ++++++++--------- Tests/UnitTests/Views/TextFieldTests.cs | 1 + Tests/UnitTests/Views/TextViewTests.cs | 13 +- Tests/UnitTests/Views/TreeViewTests.cs | 14 +- .../Drawing/CellTests.cs | 166 +- .../Drivers/AddRuneTests.cs | 36 +- .../Drivers/ContentsTests.cs | 8 +- .../Drivers/DriverTests.cs | 48 +- .../Drivers/FakeDriverTests.cs | 2 +- .../UnitTestsParallelizable/Text/RuneTests.cs | 137 +- .../Text/StringTests.cs | 206 +- .../Text/TextFormatterDrawTests.cs | 27 + .../Text/TextFormatterTests.cs | 53 +- .../View/Draw/ViewClearViewportTests.cs | 10 +- .../Draw/ViewDrawTextAndLineCanvasTests.cs | 12 +- .../Views/ListViewTests.cs | 7 +- .../Views/TextFieldTests.cs | 6 +- .../Views/TextViewTests.cs | 64 +- 53 files changed, 2654 insertions(+), 2145 deletions(-) create mode 100644 Terminal.Gui/Drawing/GraphemeHelper.cs diff --git a/Directory.Packages.props b/Directory.Packages.props index d62a1d298..2fdb4633e 100644 --- a/Directory.Packages.props +++ b/Directory.Packages.props @@ -18,7 +18,7 @@ - + diff --git a/Examples/UICatalog/Scenarios/CombiningMarks.cs b/Examples/UICatalog/Scenarios/CombiningMarks.cs index 47b8dfbc7..62181c500 100644 --- a/Examples/UICatalog/Scenarios/CombiningMarks.cs +++ b/Examples/UICatalog/Scenarios/CombiningMarks.cs @@ -16,7 +16,8 @@ public class CombiningMarks : Scenario Application.Current!.SetNeedsDraw (); var i = -1; - top.AddStr ("Terminal.Gui only supports combining marks that normalize.

Lifecycle Events Are Misnamed and Hacky + +**Problem**: Events like `Activate`, `Deactivate`, `Loaded`, `Ready`, `Closing`, `Closed`, `Unloaded` are on `Toplevel` but conceptually belong to the runnable session, not the view. + +**Consequence**: +- Events fire on the view object, mixing view lifecycle with session lifecycle +- Cannot easily monitor session changes independently of view state +- Event args reference `Toplevel` specifically +- **Hacky `ToplevelTransitionManager`**: The `Ready` event requires a separate manager class to track which toplevels have been "readied" across session transitions + +**Why is this hacky?** The `Ready` event is fired during the first `RunIteration()` (in the main loop), not during `Begin()` like other lifecycle events. This requires tracking state externally and checking every iteration. With proper CWP-aligned lifecycle, this complexity disappears - `Started` fires after `Begin()` completes, no tracking needed. + +### 6. Unclear Responsibilities + +**Problem**: It's unclear what `Toplevel` is responsible for. + +Is `Toplevel`: +- A full-screen container view? +- The base class for runnable views? +- The representation of a running session? +- A view with special overlapped arrangement? + +**Consequence**: Confused codebase where responsibilities blur. + +### 7. Violates Cancellable Work Pattern + +**Problem**: `Toplevel`'s lifecycle methods don't follow Terminal.Gui's **Cancellable Work Pattern** (CWP), which is used throughout the framework for `View.Draw`, `View.Keyboard`, `View.Command`, and property changes. + +**Consequence**: + +Current `Toplevel.OnClosing` implementation: +```csharp +internal virtual bool OnClosing(ToplevelClosingEventArgs ev) +{ + Closing?.Invoke(this, ev); // ? Event fired INSIDE virtual method + return ev.Cancel; +} +``` + +**What's wrong:** +1. **Wrong Order**: Event is raised inside the virtual method, not after +2. **No Pre-Check**: Virtual method doesn't return bool to cancel before event +3. **Inconsistent Naming**: Should be `OnStopping`/`Stopping` (cancellable) and `OnStopped`/`Stopped` (non-cancellable) +4. **Manual Checking**: `Application.RequestStop` manually checks `ev.Cancel` instead of relying on method return value + +**Impact**: +- Developers familiar with CWP from other Terminal.Gui components are confused by inconsistent patterns +- Cannot properly override lifecycle methods following the standard pattern +- Event subscription doesn't work as expected compared to other Terminal.Gui events +- Testing is harder because flow is non-standard + +### 8. View Initialization Doesn't Follow CWP + +**Problem**: `View.BeginInit/EndInit/Initialized` doesn't follow the Cancellable Work Pattern, creating inconsistency with the rest of Terminal.Gui. + +**What's Wrong:** +1. **No Pre-Notification Virtual**: No `OnInitializing()` virtual method before initialization +2. **No Cancellation**: Cannot cancel initialization +3. **Event After Work**: `Initialized` event fires after all work is done, no chance to participate +4. **Inconsistent with CWP**: Doesn't match the pattern used elsewhere in Terminal.Gui + +**Impact**: +- Inconsistent with rest of Terminal.Gui's event model +- Cannot hook into initialization at the right point in the lifecycle +- Subclasses cannot easily customize initialization behavior +- Makes the IRunnable lifecycle confusing since `Initialized` event doesn't follow CWP + +**Proposed Fix**: Add `Initializing` (cancellable) event and `OnInitializing`/`OnInitialized` virtual methods to match CWP pattern used throughout Terminal.Gui. + +## Proposed Architecture + +### Core Concept: Simplify and Clarify + +**Key Insight**: After analyzing the codebase, there's no valid use case for "non-modal runnables". Every `Toplevel` that calls `Application.Run()` blocks until `RequestStop()`. The `Modal` property only controls input routing, not the fundamental session behavior. + +**Simplified Model:** + +1. **`IRunnable`** - Interface for views that can run as **blocking** sessions with typed results +2. **`ViewArrangement.Overlapped`** - Layout mode for window management (orthogonal to runnability) +3. **Embedded Views** - Views that aren't runnable at all (e.g., `Wizard` with `Modal = false` is just a view) + +### Architecture Tenets + +1. **Interface-Based**: Use `IRunnable` interface to define runnable behavior, not inheritance +2. **Composition Over Inheritance**: Views can implement `IRunnable` without inheriting from `Toplevel` +3. **All Sessions Block**: `Application.Run()` blocks until `RequestStop()` is called (no background/non-blocking sessions) +4. **Type-Safe Results**: Generic `TResult` parameter provides compile-time type safety for return values +5. **Clean Separation**: View hierarchy (SuperView/SubViews) is independent of session hierarchy (RunnableSessionStack) +6. **Cancellable Work Pattern**: All lifecycle phases follow Terminal.Gui's Cancellable Work Pattern for consistency +7. **Result Extraction in `Stopping`**: `OnStopping()` is called before disposal, perfect for extracting `Result` + +### Result Extraction Pattern + +The `Result` property is a nullable generic (`public TResult? Result`) to represent the outcome of the runnable operation, allowing for rich result data and context. + +**Critical Timing**: `Result` must be extracted in `RaiseIsRunningChanging()` when the new value is `false`, which is called by `RequestStop()` before the run loop exits and before disposal. This ensures the data is captured while views are still accessible. + +```csharp +protected override bool RaiseIsRunningChanging () +{ + // Extract Result BEFORE disposal + // At this point views are still alive and accessible + Result = ExtractResultFromViews(); + + return base.OnStopping(); // Allow cancellation +} +``` + +--- + +## Detailed API Design + +### 1. `IRunnable` Non-Generic Base Interface + +The non-generic base interface provides common members for all runnables, enabling type-safe heterogeneous collections: + +```csharp +namespace Terminal.Gui.App; + +/// +/// Non-generic base interface for runnable views.

Usage Examples + +#### Three Forms of Run() + +**Form 1: Run with provided runnable** + +```csharp +Application app = Application.Create (); +app.Init (); + +Runnable myView = new () +{ + Width = Dim.Fill (), + Height = Dim.Fill () +}; +myView.Add (new MenuBar { /* ... */ }); +myView.Add (new StatusBar { /* ... */ }); + +app.Run (myView); // Run the specific runnable +myView.Dispose (); +app.Shutdown (); +``` + +**Form 2: Run with type parameter (generic convenience)** + +```csharp +Application app = Application.Create (); +app.Init (); + +Dialog dialog = app.Run (); // Creates and runs Dialog +// dialog.Result contains the result after it closes + +dialog.Dispose (); +app.Shutdown (); +``` + +**Form 3: Run with default container (parameterless convenience)** + +```csharp +Application app = Application.Create (); +app.Init (); + +// Subscribe to application-level event to populate the default runnable +app.IsRunningChanged += (s, e) => +{ + if (e.CurrentValue && app.TopRunnable != null) + { + // Populate app.TopRunnable with views when it starts + app.TopRunnable.Add (new MenuBar { /* ... */ }); + app.TopRunnable.Add (new Label + { + Text = "Hello World!", + X = Pos.Center (), + Y = Pos.Center () + }); + app.TopRunnable.Add (new StatusBar { /* ... */ }); + } +}; + +IRunnable mainRunnable = app.Run (); // Creates default Runnable and runs it +mainRunnable.Dispose (); + +app.Shutdown (); +``` + +**Why three forms?** +- **Form 1**: Most control, you create and configure the runnable +- **Form 2**: Convenience for creating typed runnables with default constructors +- **Form 3**: Simplest for quick apps, populate via `Starting` event + +#### Using IsRunningChanged Event + +```csharp +Runnable runnable = new (); + +// Listen for when it starts running +runnable.IsRunningChanged += (s, e) => +{ + if (e.CurrentValue) // Started running + { + // View is on the stack, initialized, and laid out + // Safe to perform post-start logic + SetupDataBindings (); + LoadInitialData (); + } + else // Stopped running + { + // Clean up resources + SaveState (); + } +}; + +app.Run (runnable); +runnable.Dispose (); +``` + +#### Override Pattern (Canceling Stop with Cleanup and Result Extraction) + +```csharp +public class MyRunnable : Runnable +{ + private TextField? _textField; + + protected override bool OnIsRunningChanging(bool oldIsRunning, bool newIsRunning) + { + if (!newIsRunning) // Stopping + { + // Extract Result BEFORE being removed from stack + if (HasUnsavedChanges ()) + { + var result = MessageBox.Query ("Unsaved Changes", + "Save before closing?", "Yes", "No", "Cancel"); + + if (result == 2) // Cancel + { + return true; // Cancel stopping + } + else if (result == 0) // Yes + { + SaveChanges (); + Result = _textField?.Text; // Extract result + } + else // No + { + Result = null; // Explicitly null (canceled) + } + } + else + { + Result = _textField?.Text; // Extract result + } + } + else // Starting + { + // Clear previous result + Result = default; + + // Can prevent starting if needed + if (!CanStart ()) + { + return true; // Cancel starting + } + } + + return base.OnIsRunningChanging (oldIsRunning, newIsRunning); + } + + protected override void OnIsRunningChanged (bool newIsRunning) + { + if (newIsRunning) // Started + { + // Post-start initialization + SetFocus (); + StartBackgroundWork (); + } + else // Stopped + { + // Cleanup after successful stop + DisconnectFromServer (); + SaveState (); + } + + base.OnIsRunningChanged (newIsRunning); + } + + protected override void OnIsModalChanged (bool newIsModal) + { + if (newIsModal) // Became modal (top of stack) + { + // Set focus, update UI for being active + UpdateTitle ("Active"); + } + else // No longer modal (another runnable on top) + { + // Dim UI, show as inactive + UpdateTitle ("Inactive"); + } + + base.OnIsModalChanged (newIsModal); + } +} +``` + +#### Modal Dialog with Automatic Result Capture + +`Dialog` implements `IRunnable` and overrides `OnIsRunningChanging` to extract result before disposal: + +```csharp +public class Dialog : Runnable +{ + private Button[]? _buttons; + + protected override bool OnIsRunningChanging(bool oldIsRunning, bool newIsRunning) + { + if (!newIsRunning) // Stopping + { + // Extract Result BEFORE views are disposed + // Find which button was clicked + Result = _buttons?.Select((b, i) => (button: b, index: i)) + .FirstOrDefault(x => x.button.HasFocus) + .index ?? -1; + } + + return base.OnIsRunningChanging(oldIsRunning, newIsRunning); + } +} + +// Usage +Dialog dialog = new (); +Application.Run (dialog); + +// Type-safe result - no casting needed +var result = dialog.Result ?? -1; + +// Pattern matching +if (dialog.Result is int buttonIndex) +{ + switch (buttonIndex) + { + case 0: + // First button clicked + break; + case 1: + // Second button clicked + break; + case -1: + // Canceled (ESC, closed) + break; + } +} +dialog.Dispose (); +``` + +This works seamlessly with buttons calling `Application.RequestStop()` in their handlers. + +#### MessageBox Example - Type-Safe and Simple + +With `Dialog` implementing `IRunnable`, MessageBox is beautifully simple: + +```csharp +// MessageBox.Query implementation (simplified) +private static int QueryFull (string title, string message, params string [] buttons) +{ + using Dialog d = new () { Title = title, Text = message }; + + // Create buttons with handlers that call RequestStop + for (var i = 0; i < buttons.Length; i++) + { + var buttonIndex = i; // Capture for closure + d.AddButton (new Button + { + Text = buttons [i], + IsDefault = (i == 0), // First button is default + Accept = (s, e) => + { + // Store which button was clicked + d.Result = buttonIndex; + Application.RequestStop (); + } + }); + } + + // Run modal - blocks until RequestStop() + Application.Run (d); + + // Type-safe result - no casting needed! + return d.Result ?? -1; // null = canceled (ESC pressed, etc.) +} +``` + +**Pattern**: Buttons set `Result` in their handlers, then call `RequestStop()`. The `OnIsRunningChanging` override can extract additional data if needed. + +#### OptionSelector Example - Type-Safe Pattern + +Custom dialog that returns a typed enum: + +```csharp +// Custom dialog that returns an Alignment enum +public class AlignmentDialog : Runnable +{ + private RadioGroup? _selector; + + public AlignmentDialog () + { + Title = "Choose Alignment"; + + _selector = new () + { + RadioLabels = new [] { "Start", "Center", "End" } + }; + + Add (_selector); + + Button okButton = new () { Text = "OK", IsDefault = true }; + okButton.Accept += (s, e) => + { + Application.RequestStop (); + }; + AddButton (okButton); + } + + protected override bool OnIsRunningChanging (bool oldIsRunning, bool newIsRunning) + { + if (!newIsRunning) // Stopping + { + // Extract the selected value BEFORE disposal + Result = _selector?.SelectedItem switch + { + 0 => Alignment.Start, + 1 => Alignment.Center, + 2 => Alignment.End, + _ => (Alignment?)null + }; + } + + return base.OnIsRunningChanging (oldIsRunning, newIsRunning); + } +} + +// Usage - type-safe! +AlignmentDialog dialog = new (); +Application.Run (dialog); + +if (dialog.Result is Alignment alignment) +{ + ApplyAlignment (alignment); // No casting needed! +} +dialog.Dispose (); +``` + +#### FileDialog Example + +```csharp +public class FileDialog : Runnable +{ + private TextField? _pathField; + + public FileDialog () + { + Title = "Open File"; + + _pathField = new () { Width = Dim.Fill () }; + Add (_pathField); + + Button okButton = new () { Text = "OK", IsDefault = true }; + okButton.Accept += (s, e) => + { + Application.RequestStop (); + }; + + AddButton (okButton); + } + + protected override bool OnIsRunningChanging (bool oldIsRunning, bool newIsRunning) + { + if (!newIsRunning) // Stopping + { + // Extract result BEFORE disposal + Result = _pathField?.Text; + } + + return base.OnIsRunningChanging (oldIsRunning, newIsRunning); + } +} + +// Usage - type-safe! +FileDialog fileDialog = new (); +Application.Run (fileDialog); + +if (fileDialog.Result is { } path) +{ + OpenFile (path); // string, no cast needed! +} +fileDialog.Dispose (); +``` + +#### Key Benefits + +1. **Zero boilerplate** - No manual Accepting handlers in MessageBox +2. **Fully type-safe** - No casting, compile-time type checking +3. **Natural C# idioms** - `null` = not accepted, pattern matching for accepted +4. **Safe disposal** - Data extracted before views are disposed +5. **Extensible** - Works with any type: `int`, `string`, enums, custom objects +6. **Clean separation** - Dialog captures data, controls handle their own Accept logic +7. **Consistent** - All lifecycle events follow Terminal.Gui's Cancellable Work Pattern + +--- + +## Migration Path + +### Phase 0: Rename `Current` to `TopRunnable` **DONE** + +- Issue #4148 +- This is a minor rename for clarity.

Add `IRunnable` (non-generic) interface alongside existing `Toplevel` +2. Add `IRunnable` (generic) interface +3. Add `Runnable` base class +4. Add `RunnableSessionToken` class +5. Update `IApplication.RunnableSessionStack` to hold `RunnableSessionToken` instead of `Toplevel` +6. Update `IApplication` to support both `Toplevel` and `IRunnable` +7. Implement CWP-based `IsRunningChanging`/`IsRunningChanged` events +8. Implement CWP-based `IsModalChanging`/`IsModalChanged` events +9. Update `Begin()`, `End()`, `RequestStop()` to raise these events +10. Add three `Run()` overloads: `Run(IRunnable)`, `Run()`, `Run()` + +### Phase 2: Migrate Existing Views + +- Issue (TBD) + +1. Make `Toplevel` implement `IRunnable` (adapter pattern for compatibility) +2. Update `Dialog` to inherit from `Runnable` instead of `Window` +3. Update `MessageBox` to use `Dialog.Result` +4.

Deprecated legacy methods and added `Obsolete` attributes to indicate their removal. Simplified method bodies using expression-bodied members and null-coalescing assignments. Enhanced lifecycle management in `ApplicationImpl` by removing redundant code and improving `SessionStack` iteration. Introduced `IToplevelTransitionManager` to handle top-level state changes. Updated `Runnable` to implement `IRunnable` with lifecycle event handling for `IsRunning` and `IsModal` states. Improved result management during lifecycle transitions. Removed legacy classes like `SessionToken` and consolidated their functionality into the new constructs. Updated and expanded the test suite to cover `IRunnable` lifecycle events, `RunnableSessionToken` behavior, and integration with `Application`. Performed code cleanup, improved readability, and updated documentation with detailed remarks and examples. Added new unit tests for edge cases and lifecycle behavior. * Implement fluent API for Init/Run/Shutdown with automatic disposal - Changed Init() to return IApplication for fluent chaining - Changed Run() to return IApplication (breaking change from TRunnable) - Changed Shutdown() to return object? (extracts and returns result from last Run()) - Added FrameworkOwnedRunnable property to track runnable created by Run() - Shutdown() automatically disposes framework-owned runnables - Created FluentExample demonstrating: Application.Create().Init().Run().Shutdown() - Disposal semantics: framework creates → framework disposes; caller creates → caller disposes Co-authored-by: tig <585482+tig@users.noreply.github.com> * New Example: Demonstrates new Fluent API using ColorPicker Conditional compilation (`#if POST_4148`) to support both a new Fluent API and a traditional approach for running `ColorPickerView`. The Fluent API simplifies the application lifecycle with method chaining and automatic disposal, while the traditional approach retains explicit lifecycle management. Refactor `ColorPickerView` to support both approaches: - Add an `instructions` label for user guidance. - Replace `_okButton` and `_cancelButton` with local `Button` instances. - Use a new `ColorPicker` with enhanced styling options. Add a warning log for WIP issue (#4148) in `ApplicationImpl.Run.cs` to highlight limitations with non-`Toplevel` views as runnables. Update `Terminal.sln` to include the new `FluentExample` project with appropriate build configurations. Improve code readability with verbatim string literals and better alignment/indentation. * Introduce `RunnableWrapper` for making any View runnable Added the `RunnableWrapper` pattern to enable any `View` to be run as a blocking session with typed results, without requiring inheritance from `Runnable` or implementation of `IRunnable`. - Added `RunnableWrapperExample` project to demonstrate usage. - Introduced `ApplicationRunnableExtensions` and `ViewRunnableExtensions` for clean, type-safe APIs to run views with or without result extraction. - Updated `CodeSharingStrategy.md` to document reduced duplication using `#if POST_4148` directives. - Added `RunnableWrapper.md` with detailed documentation and examples. - Created runnable examples in `Program.cs` showcasing various use cases. - Improved maintainability by reducing code duplication by 86% and increasing shared code by 264%. - Gated all new functionality behind the `POST_4148` feature flag for backward compatibility. * Simplified `#if POST_4148` usage to reduce duplication and improve clarity. Refactored `RunnableWrapper` to use a parameterless constructor with `required` properties, ensuring type safety and better lifecycle management. Updated `AllViewsView` with new commands, improved generic handling, and enhanced logging. Refactored `ApplicationRunnableExtensions` and `ViewRunnableExtensions` for cleaner initialization and event handling. Enhanced `TestsAllViews` to handle required properties and constraints dynamically. Updated documentation to reflect new designs and provide clearer examples. Improved overall code readability, consistency, and maintainability while leveraging modern C# features. * Update docfx documentation for IRunnable architecture - Updated View.md with comprehensive IRunnable section - Interface-based architecture explanation - Fluent API patterns and examples - Disposal semantics ("whoever creates it, owns it") - Result extraction patterns - Lifecycle properties and CWP-compliant events - Marked legacy Modal Views section for clarity - Updated application.md with IRunnable deep dive - Key features and benefits - Fluent API patterns with method chaining - Disposal semantics table - Creating runnable views with examples - Lifecycle properties and events - RunnableSessionStack management - Updated IApplication interface documentation - Updated runnable-architecture-proposal.md - Marked Phase 1 as COMPLETE ✅ - Updated status to "Phase 1 Complete - Phase 2 In Progress" - Documented all implemented features - Added bonus features (fluent API, automatic disposal) - Included migration examples All documentation is now clear, concise, and complete relative to Phase 1 implementation.

(#4411) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Initial plan * Change MessageBox to return nullable int instead of -1 Co-authored-by: tig <585482+tig@users.noreply.github.com> * Initial plan * Add fencing to prevent mixing Application models Co-authored-by: tig <585482+tig@users.noreply.github.com> * Fix fence logic to work with parallel tests Co-authored-by: tig <585482+tig@users.noreply.github.com> * WIP: Fixing Application issues. * Refactor error messages into constants Co-authored-by: tig <585482+tig@users.noreply.github.com> * Refactor ConfigurationProperty properties to use static backing fields and raise events Co-authored-by: tig <585482+tig@users.noreply.github.com> * Reset static Application properties in ResetStateStatic Co-authored-by: tig <585482+tig@users.noreply.github.com> * Refactor tests to decouple from global Application state Commented out `driver ??= Application.Driver` assignments in `DriverAssert` to prevent automatic global driver assignment. Removed `Application.ResetState(true)` calls and commented out state validation assertions in `GlobalTestSetup` to reduce dependency on global state. Reintroduced `ApplicationForceDriverTests` and `ApplicationModelFencingTests` to validate `ForceDriver` behavior and ensure proper handling of legacy and modern Application models. Skipped certain `ToAnsiTests` that rely on `Application`. Removed direct `Application.Driver` assignments in `ViewDrawingClippingTests` and `ViewDrawingFlowTests`. Performed general cleanup of redundant code and unused imports to simplify the codebase. * WIP: Fixed Parallel tests; non-Parallel still broken Refactor application model usage tracking Refactored `ApplicationModelUsage` into a public enum in the new `Terminal.Gui.App` namespace, making it accessible across the codebase. Replaced the private `_modelUsage` field in `ApplicationImpl` with a public static `ModelUsage` property to improve clarity and accessibility. Renamed error message constants for consistency and updated methods like `SetInstance` and `MarkInstanceBasedModelUsed` to use the new `ModelUsage` property. Removed the private `ApplicationModelUsage` enum from `ApplicationImpl`. Updated test cases to use `ApplicationImpl.Instance` instead of `Application.Create` to enforce the legacy static model. Skipped obsolete tests in `ApplicationForceDriverTests` and added null checks in `DriverAssert` and `SelectorBase` to handle edge cases. Commented out an unused line in `WindowsOutput` and made general improvements to code readability, maintainability, and consistency. * WIP: Almost there! Refactored tests and code to align with the modern instance-based application model. Key changes include: - Disabled Sixel rendering in `OutputBase.cs` due to dependency on legacy static `Application` object. - Hardcoded `force16Colors` to `false` in `WindowsOutput.cs` with a `BUGBUG` note. - Updated `ApplicationImplTests` to use `ApplicationImpl.SetInstance` and return `ApplicationImpl.Instance`. - Refactored `ApplicationModelFencingTests` to use `Application.Create()` and added `ResetModelUsageTracking()` for model switching. - Removed legacy `DriverTests` and reintroduced updated versions with cross-platform driver tests. - Reverted `ArrangementTests` and `ShortcutTests` to use legacy static `ApplicationImpl.Instance`. - Reintroduced driver tests in `DriverTests.cs` with modern `Application.Create()` and added `TestTop` for driver content verification. - General cleanup, including removal of outdated code and addition of `BUGBUG` notes for temporary workarounds. * Fixed all modelusage bugs? Replaced static `Application` references with instance-based `App` context across the codebase. Updated calls to `Application.RequestStop()` and `Application.Screen` to use `App?.RequestStop()` and `App?.Screen` for better encapsulation and flexibility. Refactored test infrastructure to align with the new context, including reintroducing `FakeApplicationFactory` and `FakeApplicationLifecycle` for testing purposes. Improved logging, error handling, and test clarity by adding `logWriter` support and simplifying test setup. Removed redundant or obsolete code, such as `NetSequences` and the old `FakeApplicationFactory` implementation. Updated documentation to reflect the new `IApplication.RequestStop()` usage. * merged * Refactor KeyboardImpl and modernize MessageBoxTests Refactored the `KeyboardImpl` class to remove hardcoded default key values, replacing them with uninitialized fields for dynamic configuration. Updated key binding logic to use `ReplaceCommands` instead of `Add` for better handling of dynamic changes. Removed unnecessary `KeyBindings.Clear()` calls to avoid side effects. Rewrote `MessageBoxTests.cs` to improve readability, maintainability, and adherence to modern C# standards. Enabled nullable reference checks, updated the namespace, and restructured test methods for clarity. Marked non-functional tests with `[Theory(Skip)]` and improved test organization with parameterized inputs. Enhanced test assertions, lifecycle handling, and error handling across the test suite. Updated `UICatalog_AboutBox` to use multiline string literals for expected outputs. These changes improve the overall maintainability and flexibility of the codebase. * Atempt to fix windows only CI/CD Unit tests failure Refactor Application lifecycle and test cleanup Refactored the `Application` class to phase out legacy static properties `SessionStack` and `TopRunnable` from `Application.Current.cs`. These were reintroduced in a new file `Application.TopRunnable.cs` for better modularity, while retaining their `[Obsolete]` status. Updated `ApplicationPopoverTests.cs` to replace `Application.ResetState(true)` with `Application.Shutdown()` for consistent application state cleanup. Added explicit cleanup for `Application.TopRunnable` in relevant test cases to ensure proper resource management. Adjusted namespaces and `using` directives to support the new structure. These changes improve code organization and align with updated application lifecycle management practices. * Fixes # - Dispose TopRunnable in cleanup logic Updated the `finally` block in `ApplicationPopoverTests` to dispose of the `Application.TopRunnable` object if it is not null, ensuring proper resource cleanup. Previously, the property was being set to `null` without disposal. The `Application.Shutdown()` call remains unchanged. * Improve thread safety, reduce static dependencies, and align the codebase with the updated `IApplication` interface. Refactored the `MainThreadId` property to improve encapsulation: - Updated `Application.MainThreadId` to use `ApplicationImpl.Instance` directly. - Added `MainThreadId` to `ApplicationImpl` and `IApplication`. - Removed redundant `MainThreadId` from `ApplicationImpl.Run.cs`. Updated `EnqueueMouseEvent` to include an `IApplication?` parameter: - Modified `FakeInputProcessor`, `InputProcessorImpl`, and `WindowsInputProcessor` to support the new parameter. - Updated `IInputProcessor` interface to reflect the new method signature. - Adjusted `GuiTestContext` and `EnqueueMouseEventTests` to pass `IApplication` where required. Improved test coverage and code maintainability: - Added test cases for negative positions and empty mouse events. - Commented out legacy code in `GraphView` and `FakeDriverBase`. - Enhanced readability in `EnqueueMouseEventTests`. These changes improve thread safety, reduce static dependencies, and align the codebase with the updated `IApplication` interface. * Fixed more bugs. Enabled nullable reference types across multiple files to improve code safety. Refactored and modularized test classes, improving readability and maintainability. Removed outdated test cases and added new tests for edge cases, including culture-specific and non-Gregorian calendar handling. Addressed timeout issues in `ScenarioTests` with a watchdog timer and improved error handling. Updated `ApplicationImplTests` to use instance fields instead of static references for better test isolation. Refactored `ScenarioTests` to dynamically load and test all UI Catalog scenarios, with macOS-specific skips for known issues. Aligned `MessageBox.Query` calls with updated API signatures. Performed general code cleanup, including removing unused directives, improving formatting, and consolidating repetitive logic into helper methods. * Made the `InputBindings` class thread-safe by replacing the internal `Dictionary` with `ConcurrentDictionary`. This fixes parallel test failures where "Collection was modified; enumeration operation may not execute" exceptions were thrown. ## Changes Made ### 1. InputBindings.cs - **File**: `Terminal.Gui/Input/InputBindings.cs` - **Change**: Replaced `Dictionary` with `ConcurrentDictionary` - **Key modifications**: - Changed `_bindings` from `Dictionary` to `ConcurrentDictionary` - Updated `Add()` methods to use `TryAdd()` instead of checking with `TryGet()` then `Add()` - Updated `Remove()` to use `TryRemove()` (no need to check existence first) - Updated `ReplaceCommands()` to use `ContainsKey()` instead of `TryGet()` - Added `.ToList()` to `GetAllFromCommands()` to create a snapshot for safe enumeration - Added comment explaining that `ConcurrentDictionary` provides snapshot enumeration in `GetBindings()` - Added `.ToArray()` to `Clear(Command[])` to create snapshot before iteration ### 2. Thread Safety Test Suite - **File**: `Tests/UnitTestsParallelizable/Input/InputBindingsThreadSafetyTests.cs` - **New file** with comprehensive thread safety tests: - `Add_ConcurrentAccess_NoExceptions` - Tests concurrent additions - `GetBindings_DuringConcurrentModification_NoExceptions` - Tests enumeration during modifications - `TryGet_ConcurrentAccess_ReturnsConsistentResults` - Tests concurrent reads - `Clear_ConcurrentAccess_NoExceptions` - Tests concurrent clearing - `Remove_ConcurrentAccess_NoExceptions` - Tests concurrent removals - `Replace_ConcurrentAccess_NoExceptions` - Tests concurrent replacements - `GetAllFromCommands_DuringModification_NoExceptions` - Tests LINQ queries during modifications - `MixedOperations_ConcurrentAccess_NoExceptions` - Tests mixed operations (add/read/remove) - `KeyBindings_ConcurrentAccess_NoExceptions` - Tests actual `KeyBindings` class - `MouseBindings_ConcurrentAccess_NoExceptions` - Tests actual `MouseBindings` class ## Benefits of ConcurrentDictionary Approach 1. **Lock-Free Reads**: Most read operations don't require locks, improving performance 2. **Snapshot Enumeration**: Built-in support for safe enumeration during concurrent modifications 3. **Simplified Code**: No need for explicit `lock` statements or lock objects 4. **Better Scalability**: Multiple threads can read/write simultaneously 5. **No "Collection was modified" Exceptions**: Enumeration creates a snapshot ## Performance Characteristics - **Read Operations**: Lock-free, very fast - **Write Operations**: Uses fine-grained locking internally, minimal contention - **Memory Overhead**: Slightly higher than `Dictionary` but negligible in practice - **Enumeration**: Creates a snapshot, safe for concurrent modifications ## Test Results - **Original failing test now passes**: `ApplicationImplTests.Init_CreatesKeybindings` - **10 new thread safety tests**: All passing - **All 11,741 parallelizable tests**: All passing (11,731 passed, 10 skipped) - **All 1,779 non-parallelizable tests**: All passing (1,762 passed, 17 skipped) - **No compilation errors**: Clean build with no xUnit1031 warnings (suppressed with pragmas) ## Verification The original failure was: ``` System.InvalidOperationException: Collection was modified; enumeration operation may not execute. ``` This occurred in parallelizable tests when multiple threads accessed `KeyBindings.GetBindings()` simultaneously. The `ConcurrentDictionary` implementation resolves this by providing thread-safe operations and snapshot enumeration. ## Notes - The xUnit1031 warnings about using `Task.WaitAll` instead of `async/await` have been suppressed with `#pragma warning disable xUnit1031` directives, as these are intentional blocking operations in stress tests that test concurrent scenarios - All existing functionality is preserved; this is a drop-in replacement - No changes to public API surface - Existing tests continue to pass * Make InputBindings and KeyboardImpl thread-safe for concurrent access Replace Dictionary with ConcurrentDictionary in InputBindings and KeyboardImpl to enable safe parallel test execution and multi-threaded usage. Changes: - InputBindings: Replace Dictionary with ConcurrentDictionary for _bindings - InputBindings: Make Replace() atomic using AddOrUpdate instead of Remove+Add - InputBindings: Make ReplaceCommands() atomic using AddOrUpdate - InputBindings: Add IsValid() check to both Add() overloads - InputBindings: Add defensive .ToList()/.ToArray() for safe LINQ enumeration - KeyboardImpl: Replace Dictionary with ConcurrentDictionary for _commandImplementations - KeyboardImpl: Change AddKeyBindings() to use ReplaceCommands for idempotent initialization - Add 10 comprehensive thread safety tests for InputBindings - Add 9 comprehensive thread safety tests for KeyboardImpl The ConcurrentDictionary implementation provides: - Lock-free reads for better performance under concurrent access - Atomic operations for Replace/ReplaceCommands preventing race conditions - Snapshot enumeration preventing "Collection was modified" exceptions - No breaking API changes - maintains backward compatibility All 11,750 parallelizable tests pass (11,740 passed, 10 skipped). Fixes race conditions that caused ApplicationImplTests.Init_CreatesKeybindings to fail intermittently during parallel test execution. * Decouple ApplicationImpl from Application static props Removed initialization of `Force16Colors` and `ForceDriver` from `Application` static properties in the `ApplicationImpl` constructor. The class still subscribes to the `Force16ColorsChanged` and `ForceDriverChanged` events, but no longer sets initial values for these properties. This change simplifies the constructor and reduces coupling between `ApplicationImpl` and `Application`. * Refactored keyboard initialization in `ApplicationImpl` to use `Application` static properties for default key assignments, ensuring synchronization with pre-`Init()` changes. Improved `KeyboardImpl` initialization to avoid premature `ApplicationImpl.Instance` access, enhancing testability. Standardized constant naming conventions and improved code readability in thread safety tests for `KeyboardImpl` and `InputBindings`. Updated `TestInputBindings` implementation for clarity and conciseness. Applied consistent code style improvements across files, including spacing, formatting, and variable naming, to enhance maintainability and readability. * Fix race conditions in parallel tests - thread-safe ApplicationImpl and KeyboardImpl Fixes intermittent failures in parallel tests caused by three separate race conditions: 1. **KeyboardImpl constructor race condition** - Constructor was accessing Application.QuitKey/ArrangeKey/etc which triggered ApplicationImpl.Instance getter, setting ModelUsage=LegacyStatic before Application.Create() was called - Changed constructor to initialize keys with hard-coded defaults instead - Added synchronization from Application static properties during Init() 2. **InputBindings.Replace() race condition** - Between GetOrAdd(oldEventArgs) and AddOrUpdate(newEventArgs), another thread could modify bindings, causing stale data to overwrite valid bindings - Added early return for same-key case (oldEventArgs == newEventArgs) - Kept atomic operations with proper updateValueFactory handling - Added detailed thread-safety documentation 3. **ApplicationImpl model usage fence checks race condition** - Two threads calling Init() simultaneously could both pass fence checks before either set ModelUsage, allowing improper model mixing - Added _modelUsageLock for thread-safe synchronization - Made all ModelUsage operations atomic (Instance getter, SetInstance, MarkInstanceBasedModelUsed, ResetModelUsageTracking, Init fence checks) **Files Changed:** - Terminal.Gui/App/ApplicationImpl.cs - Added _modelUsageLock, made all ModelUsage access thread-safe - Terminal.Gui/App/ApplicationImpl.Lifecycle.cs - Thread-safe fence checks in Init(), sync keyboard keys from Application properties - Terminal.Gui/App/Keyboard/KeyboardImpl.cs - Fixed constructor to not trigger ApplicationImpl.Instance - Terminal.Gui/Input/InputBindings.cs - Fixed Replace() race condition with proper atomic operations **Testing:** - All 11 ApplicationImplTests pass - All 9 KeyboardImplThreadSafetyTests pass - All 10 InputBindingsThreadSafetyTests pass - No more intermittent "Cannot use modern instance-based model after using legacy static Application model" errors in parallel test execution The root cause was KeyboardImpl constructor accessing Application static properties during object creation, which would lazily initialize ApplicationImpl.Instance and set the wrong ModelUsage before Application.Create() could mark it as InstanceBased. * Warning cleanup * docs: Add comprehensive MessageBox and Clipboard API documentation - Updated MessageBox class docs with nullable return value explanation - Created docfx/docs/messagebox-clipboard-changes-v2.md migration guide - Updated migratingfromv1.md with quick links to major changes - Created PR-SUMMARY.md documenting all changes - Added examples for both instance-based and legacy patterns - Documented application model fencing and thread safety improvements The documentation covers: • MessageBox nullable int? returns (null = cancelled) • Clipboard refactoring from static to instance-based • Application model usage fencing to prevent pattern mixing • Thread safety improvements in KeyboardImpl and InputBindings • Complete migration guide with code examples • Benefits and rationale for all changes * Refactor static properties to use backing fields Refactored static properties in multiple classes (`Button`, `CheckBox`, `Dialog`, `FrameView`, `MessageBox`, `StatusBar`, and `Window`) to use private backing fields for better encapsulation and configurability. Default values are now stored in private static fields, allowing overrides via configuration files (e.g., `Resources/config.json`). Updated property definitions to use `get`/`set` accessors interacting with the backing fields. Retained the `[ConfigurationProperty]` attribute to ensure runtime configurability. Removed redundant code, improved XML documentation, adjusted namespace declarations for consistency, and performed general code cleanup to enhance readability and maintainability. * Fix Windows-only parallel test failure by preventing ConfigurationManager from triggering ApplicationImpl.Instance Problem: `MessageBoxTests.Location_And_Size_Correct` was failing only on Windows in parallel tests with: System.InvalidOperationException: Cannot use modern instance-based model (Application.Create) after using legacy static Application model (Application.Init/ApplicationImpl.Instance). Root Cause (maybe): View classes (MessageBox, Dialog, Window, Button, CheckBox, FrameView, StatusBar) had `[ConfigurationProperty]` decorated auto-properties with inline initializers. When ConfigurationManager's module initializer scanned assemblies using reflection, accessing these auto-properties could trigger lazy initialization of other static members, which in some cases indirectly referenced `ApplicationImpl.Instance`, marking the model as "legacy" before parallel tests called `Application.Create()`. Solution: Converted all `[ConfigurationProperty]` auto-properties in View classes to use private backing fields with explicit getters/setters, matching the pattern used by `Application.QuitKey`. This prevents any code execution during reflection-based property discovery. Files Changed: - Terminal.Gui/Views/MessageBox.cs - 4 properties converted - Terminal.Gui/Views/Dialog.cs - 6 properties converted - Terminal.Gui/Views/Window.cs - 2 properties converted - Terminal.Gui/Views/Button.cs - 2 properties converted - Terminal.Gui/Views/CheckBox.cs - 1 property converted - Terminal.Gui/Views/FrameView.cs - 1 property converted - Terminal.Gui/Views/StatusBar.cs - 1 property converted Test Reorganization: - Moved `ConfigurationManagerTests.GetConfigPropertiesByScope_Gets` from UnitTestsParallelizable to UnitTests (defines custom ConfigurationProperty which affects global state) - Moved `SourcesManagerTests.Sources_StaysConsistentWhenUpdateFails` from UnitTestsParallelizable to UnitTests (modifies static ConfigurationManager.ThrowOnJsonErrors property) Best Practice: All `[ConfigurationProperty]` decorated static properties should use private backing fields to avoid triggering lazy initialization during ConfigurationManager's module initialization. Fixes: Windows-only parallel test failure in MessageBoxTests * Add thread-safety to CollectionNavigator classes - Add lock-based synchronization to CollectionNavigatorBase for _searchString and _lastKeystroke fields - Add lock-based synchronization to CollectionNavigator for Collection property access - Protect ElementAt and GetCollectionLength methods with locks - Add 6 comprehensive thread-safety tests covering: - Concurrent SearchString access - Concurrent Collection property access - Concurrent navigation operations (50 parallel tasks) - Concurrent collection modification with readers/writers - Concurrent search string changes - Stress test with 100 tasks × 1000 operations each All tests pass (31/31) including new thread-safety tests. The implementation uses lock-based synchronization rather than concurrent collections because: - IList interface is not thread-safe by design - CollectionNavigator is internal and used by UI components (ListView/TreeView) - Matches existing Terminal.Gui patterns (Scope, ConfigProperty) - Provides simpler and more predictable behavior Fixes thread-safety issues when CollectionNavigator is accessed from multiple threads. * cleanup * Run parallel unit tests 10 times with varying parallelization to expose concurrency issues Co-authored-by: tig <585482+tig@users.noreply.github.com> * Fix parallel unit tests workflow - use proper xUnit parallelization parameters Co-authored-by: tig <585482+tig@users.noreply.github.com> * Fix environment variable reference in workflow - use proper bash syntax Co-authored-by: tig <585482+tig@users.noreply.github.com> * Run parallel tests 10 times sequentially instead of matrix expansion Co-authored-by: tig <585482+tig@users.noreply.github.com> * Make ConfigurationManager thread-safe - use ConcurrentDictionary and add locks Co-authored-by: tig <585482+tig@users.noreply.github.com> * Add Debug.Fail to detect legacy Application usage in parallelizable tests Co-authored-by: tig <585482+tig@users.noreply.github.com> * Move ScrollSliderTests to UnitTests project - they access legacy Application model Co-authored-by: tig <585482+tig@users.noreply.github.com> * Revert ScrollSliderTests move and document root cause analysis Co-authored-by: tig <585482+tig@users.noreply.github.com> * Remove Debug.Fail and move ScrollSliderTests to UnitTests project Co-authored-by: tig <585482+tig@users.noreply.github.com> * Re-add Debug.Fail to detect legacy Application usage in parallelizable tests Co-authored-by: tig <585482+tig@users.noreply.github.com> * Refactor tests and improve parallelization support Commented out `Debug.Fail` statements in `Application.Lifecycle.cs` and `ApplicationImpl.cs` to prevent interruptions during parallel tests. Refactored `ToString` in `ApplicationImpl.cs` to use an expression-bodied member and removed unused imports. Rewrote tests in `ClipRegionTests.cs` and `ScrollSliderTests.cs` to remove global state dependencies and migrated them to the `UnitTests_Parallelizable` namespace. Enabled nullable annotations and updated assertions for clarity and modern patterns. Improved test coverage by adding scenarios for clamping, layout, and size calculations. Updated `README.md` to include `[SetupFakeApplication]` in the list of patterns that block parallelization and clarified migration guidelines. Replaced `[SetupFakeDriver]` with `[SetupFakeApplication]` in examples. Added `` to `UnitTests.csproj` for better organization. Adjusted test project references to reflect test migration. Enhanced test output validation in `ScrollSliderTests.cs`. Removed redundant test cases and improved documentation to align with modern C# practices and ensure maintainability. * marked as a "TODO" for potential future configurability. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: tig <585482+tig@users.noreply.github.com> Co-authored-by: Tig --- .github/workflows/unit-tests.yml | 102 ++- .gitignore | 1 + Examples/Example/Example.cs | 4 +- Examples/NativeAot/Program.cs | 4 +- Examples/RunnableWrapperExample/Program.cs | 57 +- Examples/SelfContained/Program.cs | 4 +- Examples/UICatalog/Scenario.cs | 6 +- Examples/UICatalog/Scenarios/Adornments.cs | 16 +- .../AnimationScenario/AnimationScenario.cs | 2 +- Examples/UICatalog/Scenarios/Bars.cs | 10 +- Examples/UICatalog/Scenarios/Buttons.cs | 6 +- Examples/UICatalog/Scenarios/ChineseUI.cs | 5 +- .../Scenarios/ConfigurationEditor.cs | 6 +- Examples/UICatalog/Scenarios/ContextMenus.cs | 10 +- Examples/UICatalog/Scenarios/CsvEditor.cs | 30 +- Examples/UICatalog/Scenarios/Dialogs.cs | 2 +- .../UICatalog/Scenarios/DynamicStatusBar.cs | 10 +- Examples/UICatalog/Scenarios/Editor.cs | 21 +- .../Scenarios/EditorsAndHelpers/DimEditor.cs | 2 +- .../Scenarios/EditorsAndHelpers/PosEditor.cs | 2 +- .../UICatalog/Scenarios/FileDialogExamples.cs | 10 +- Examples/UICatalog/Scenarios/Generic.cs | 2 +- Examples/UICatalog/Scenarios/HexEditor.cs | 8 +- Examples/UICatalog/Scenarios/Images.cs | 6 +- .../UICatalog/Scenarios/InteractiveTree.cs | 2 +- Examples/UICatalog/Scenarios/KeyBindings.cs | 8 +- Examples/UICatalog/Scenarios/ListColumns.cs | 2 +- Examples/UICatalog/Scenarios/MessageBoxes.cs | 18 +- .../UICatalog/Scenarios/MultiColouredTable.cs | 2 +- Examples/UICatalog/Scenarios/Navigation.cs | 4 +- Examples/UICatalog/Scenarios/Notepad.cs | 16 +- Examples/UICatalog/Scenarios/RunTExample.cs | 6 +- .../Scenarios/RuneWidthGreaterThanOne.cs | 6 +- Examples/UICatalog/Scenarios/Shortcuts.cs | 2 +- .../Scenarios/SingleBackgroundWorker.cs | 8 +- Examples/UICatalog/Scenarios/TableEditor.cs | 14 +- Examples/UICatalog/Scenarios/Transparent.cs | 4 +- .../UICatalog/Scenarios/ViewportSettings.cs | 4 +- .../Scenarios/WindowsAndFrameViews.cs | 6 +- Examples/UICatalog/Scenarios/WizardAsView.cs | 9 +- Examples/UICatalog/Scenarios/Wizards.cs | 481 ++++++------ Examples/UICatalog/UICatalogTop.cs | 1 + Terminal.Gui/App/Application.Clipboard.cs | 15 + Terminal.Gui/App/Application.Driver.cs | 36 +- Terminal.Gui/App/Application.Lifecycle.cs | 21 +- Terminal.Gui/App/Application.Mouse.cs | 14 +- Terminal.Gui/App/Application.Navigation.cs | 58 +- Terminal.Gui/App/Application.Run.cs | 30 +- ....Current.cs => Application.TopRunnable.cs} | 2 +- Terminal.Gui/App/ApplicationImpl.Lifecycle.cs | 152 ++-- Terminal.Gui/App/ApplicationImpl.Run.cs | 13 +- Terminal.Gui/App/ApplicationImpl.cs | 148 +++- Terminal.Gui/App/ApplicationModelUsage.cs | 16 + Terminal.Gui/App/ApplicationNavigation.cs | 2 +- .../App/ApplicationRunnableExtensions.cs | 2 +- Terminal.Gui/App/Clipboard/Clipboard.cs | 32 + Terminal.Gui/App/IApplication.cs | 31 +- Terminal.Gui/App/IterationEventArgs.cs | 5 -
