* Refactor DriverImpl and OutputBase for maintainability
Refactored `DriverImpl` to remove `IDisposable` and streamline event
handling, including replacing `OnSizeMonitorOnSizeChanged` with an
inline lambda. Reintroduced `SizeChanged` and updated `SetScreenSize`
to invoke it. Moved `SupportsTrueColor` from `OutputBase` to
`DriverImpl` and reintroduced `Force16Colors` with updated logic.
Reintroduced and updated several `OutputBuffer`-related properties
and methods in `DriverImpl`, including `Screen`, `Clip`, `Cols`, and
`Contents`. Moved `Clipboard` from `OutputBase` to `DriverImpl` and
initialized it with `FakeClipboard`. Simplified `Refresh` and `ToAnsi`
methods in `DriverImpl`.
Removed `Force16Colors` from `OutputBase` and simplified method
signatures, including `ToAnsi` and `BuildAnsiForRegion`. Fixed a
parameter name typo in `AppendOrWriteAttribute`. Made minor code
formatting adjustments.
These changes improve code maintainability, reduce redundancy, and
align the implementation with updated design requirements.
* Refactor Force16Colors handling and improve UICatalog
Refactored the `Force16Colors` property:
- Moved it from `DriverImpl` to `IOutput` and `OutputBase`.
- Simplified its management by removing redundant logic.
- Added `OnDriverOnForce16ColorsChanged` to handle updates.
Updated `UICatalogRunnable`:
- Replaced `Driver.Force16Colors` with `Application.Driver.Force16Colors`.
- Added an `F7` shortcut to toggle `Force16Colors`.
- Removed redundant event handlers and improved formatting.
Updated `config.json`:
- Replaced `Application.Force16Colors` with `Driver.Force16Colors`.
- Improved theme configuration formatting for readability.
Other changes:
- Removed the `force16Colors` parameter from `IOutput.ToAnsi`.
- Improved diagnostics handling in `UICatalogRunnable`.
- General code cleanup for readability and maintainability.
* Refactor `Force16Colors` access and improve null safety
Refactored `Force16Colors` property access to use `Application.Driver!`
for null safety and consistency. Updated event handlers to align with
this pattern. Replaced nullable `DrawContext?` parameters with
non-nullable `DrawContext` in `OnDrawingContent` overrides across
multiple classes to enforce stricter nullability checks.
Removed unused `_cachedCursorVisibility` field in `OutputBase.cs` and
cleaned up commented-out legacy code in `UICatalogRunnable.cs`. Updated
XML documentation to reflect method signature changes and property
references. Refactored `Shortcut` example in documentation for
consistency.
Replaced `Application.LayoutAndDraw` with `SetNeedsDraw` for marking
views as needing redraw. Performed general code cleanup to remove
redundant code and improve consistency.
* Refactor ForceDriver and Force16Colors properties
Removed `[Obsolete]` from `Application.ForceDriver`, making it a stable API. Added comments to clarify its role as a configuration property and its synchronization with `IApplication.ForceDriver`. Introduced `_forceDriver` as a private backing field.
Removed `Force16Colors` from `ApplicationImpl` and eliminated reset logic for `ForceDriver` and `Force16Colors` during shutdown, shifting state management responsibility to the library user.
Updated comments in `Driver.cs` to document `Force16Colors` as a configuration property and its synchronization with `IDriver.Force16Colors`. Retained `_force16Colors` as a private backing field for configuration overrides.
* Updated docs
* There is no way to detect Sixel transparency and so relying in VTS or Xterm with transparency
* Fix detect Sixel unit tests with the adjusting code
* Refactored Output.
* MErging
* - Added `OnDriverOnForce16ColorsChanged` method to handle `Driver.Force16ColorsChanged` events and update the `Force16Colors` property.
- Implemented `IDisposable` to ensure proper cleanup of resources, including unsubscribing from `SizeMonitor.SizeChanged` and `Driver.Force16ColorsChanged` events, and disposing of `_output`.
- Replaced inline `SizeMonitor.SizeChanged` event handler with a dedicated method, `OnSizeMonitorOnSizeChanged`, for better readability and maintainability.
- Simplified the `Screen` property by removing commented-out code and directly returning a `Rectangle` based on `OutputBuffer` dimensions.
- Updated the `Force16Colors` property to use `_output` for both getting and setting its value.
- Performed general cleanup, including removing unused code and improving code structure.
* merged
* Refactor Sixel handling with ConcurrentQueue
Replaced `List<SixelToRender>` with `ConcurrentQueue<SixelToRender>`
to improve thread safety and performance in sixel management.
Updated the `Images` class to avoid unnecessary removal and
re-creation of sixel objects by updating existing ones in place.
Refactored `Application.Sixel` to return a `ConcurrentQueue` and
introduced `GetSixels` in `IDriver` and `IOutput` for consistent
access. Updated `OutputBase` to use a private `ConcurrentQueue`
and adjusted rendering logic accordingly.
Removed legacy and redundant code, including `Application.Driver?.Sixel.Clear()`
and unused properties in `DriverImpl` and `ApplicationImpl`. Updated
tests in `OutputBaseTests` to align with the new implementation.
Added `using System.Collections.Concurrent` where necessary and
improved documentation to reflect the changes. These updates
enhance thread safety, simplify the codebase, and align with
modern concurrent programming practices.
* Tweak
* Refactor DriverImpl to use Dispose and improve modularity
Replaced `Driver.End()` with `Driver.Dispose()` across the codebase, aligning with the `IDisposable` pattern for proper resource cleanup. Updated `DriverImpl` to implement `Dispose`, ensuring event unsubscriptions and resource disposal.
Enhanced `DriverImpl` structure by organizing code into logical regions, improving modularity and readability. Refactored and reintroduced methods and properties like `Clipboard`, `Screen`, `SetScreenSize`, `Cols`, `Rows`, and others for better encapsulation.
Updated the `IDriver` interface to include `IDisposable` and reorganized it into regions. Added new methods and properties such as `Init`, `Refresh`, `Suspend`, `QueueAnsiRequest`, and `ToAnsi`.
Refactored unit tests to replace `driver.End()` with `driver.Dispose()` and ensured proper resource cleanup. Improved code comments and documentation for better clarity.
Aligned with modern C# practices, adopting features like null-coalescing operators and pattern matching. Removed redundant code, addressed some TODOs, and modularized the codebase for maintainability and extensibility.
* Refactor driver docs and update View.Driver usage
Updated `application.md` to clarify the purpose of the `View.Driver` property, replacing the obsolete `Application.Driver`. Added a reference to the "Drivers Deep Dive" documentation for further details.
Refactored the `OnDrawContent` method to use the `Driver` property, ensuring compatibility with the new driver architecture.
Added a new section, "Testing with the New Architecture," to `application.md`, highlighting the improved testability of the instance-based architecture.
Expanded and reorganized `drivers.md` to provide a detailed breakdown of the `IDriver` interface, including lifecycle, components, screen and display, color support, content buffer, drawing, cursor, input events, and ANSI escape sequences. Introduced new subsections for clarity and emphasized the modular design for maintainability.
Added a note in `drivers.md` discouraging direct access to the `Driver` and recommending higher-level abstractions like `Terminal.Gui.App.Application.Screen` and `Terminal.Gui.ViewBase.View` methods for positioning and drawing.
* Refactor IsVirtualTerminal to IsLegacyConsole
Replaced the `IsVirtualTerminal` property with `IsLegacyConsole` across the codebase to better represent legacy versus modern terminal environments. Updated logic in `SixelSupportDetector`, `DriverImpl`, and `OutputBase` to use the new property.
Refactored tests to align with the updated property, including renaming test methods, adjusting mock setups, and replacing `VirtualTerminalTests` with `LegacyConsoleTests`.
Simplified `WindowsOutput` implementation to handle console modes and sixel rendering based on `IsLegacyConsole`. Removed redundant code related to `IsVirtualTerminal`.
Improved code readability and maintainability by using more descriptive property names and ensuring consistency across the codebase. Updated `.DotSettings` with new entries.

* Fix formatting and typo in code and documentation
Improved code readability in `LineDrawing.cs` by fixing spacing
around the ternary operator in `Width` and `Y` property assignments.
Corrected a typo in `drivers.md` by changing "Configuraiton Manager"
to "Configuration Manager" for accurate documentation.
* Test failure casued by assert left in by accident.
* Added a workaround in `OutputBase.cs` to address dirty cell handling in legacy console mode by marking all buffer cells as dirty.
Refactored `_disableMouseCb` event handling in `UICatalogRunnable.cs` to use the `Selecting` event for toggling `Application.IsMouseDisabled`. Simplified `MouseImpl.cs` by converting `App` to an auto-implemented property and removing redundant namespace usage.
Streamlined logging in `WindowsOutput.cs` by replacing verbose `Logging.Logger` calls with shorter alternatives (`Logging.Information`, `Logging.Error`, etc.).
* Update theme and remove unused ListView component
The application's default theme configuration was updated from "Light" to "Amber Phosphor" by modifying the `ConfigurationManager.RuntimeConfig` value.
Additionally, the `ListView` component in the `ExampleWindow` class was removed. This included its initialization, layout properties (`Y`, `Height`, `Width`), and its data source (["One", "Two", "Three", "Four"]).
* Increase safety timeout in NestedRunTimeoutTests to 10s
The timeout duration for the safety mechanism in the
`NestedRunTimeoutTests` class was increased from 5000ms (5s)
to 10000ms (10s). This change allows the app more time to
complete before triggering the safety timeout, reducing the
likelihood of premature termination during long-running tests.
Refactor and enhance test coverage
Refactored `Load_WithInvalidJson_AddsJsonError` test in `SourcesManagerTests.cs` to improve organization and added a note about its impact on parallel execution. Increased the safety timeout in `NestedRunTimeoutTests.cs` from 5 seconds to 10 seconds to address potential premature test timeouts.
* Handle null Driver gracefully in event subscription
Replaced `ArgumentNullException.ThrowIfNull(Driver)` with a null-check conditional in `SubscribeDriverEvents` and `UnsubscribeDriverEvents`. If `Driver` is `null`, the methods now log an error using `Logging.Error` and return early. This prevents potential exceptions and improves error handling.
