Enhanced `IConsoleDriver` with detailed remarks on implementations. Revised test cases to align with updated `Application.Init` behavior: - Replaced `FakeDriver` with `null` and `driverName: "fake"`. - Skipped or commented out tests incompatible with new logic. - Improved formatting and removed redundant setup code. Improved code style and consistency across the codebase: - Standardized parameter formatting and spacing. - Removed outdated comments and unused code. General cleanup to enhance readability and maintainability. * Warp fix copilot (#4278) * More fixes (#4279) * Fixes/works around test failures and temporarily disable failing test Updated `FakeDriver` to set `RunningUnitTests` to `true` and initialize dimensions using `FakeConsole`. Modified `TestRespondersDisposedAttribute` to set `ConsoleDriver.RunningUnitTests` in the `Before` method, ensuring proper behavior during unit tests. Temporarily disabled the `Button_CanFocus_False_Raises_Accepted_Correctly` test in `ViewCommandTests` by adding a `Skip` parameter to the `[Fact]` attribute, referencing issue #4270. * Allow all tests to run despite failures in UnitTests Modified the `dotnet test` command in the `Run UnitTestsParallelizable` step to set `xunit.stopOnFail` to `false`. This ensures that the test runner does not stop execution on the first failure, allowing all tests to execute regardless of individual test outcomes. * Refactor ApplicationScreenTests for cleaner setup/teardown Refactored `ClearContents_Called_When_Top_Frame_Changes` test: - Added `[AutoInitShutdown]` attribute for automatic lifecycle management. - Replaced manual `Application.Init` and `Application.Top` setup with `Application.Begin` and `RunState`. - Simplified event handling by defining `ClearedContents` handler inline. - Removed explicit cleanup logic, relying on `Application.End` for teardown. Updated `using` directives to include `UnitTests` namespace. * Attempt to fix intermittent local test failures. Update ApplicationImpl initialization parameter Changed the second parameter of the `impl.Init` method in the `FakeApplicationFactory` class from `"dotnet"` to `"fake"`. * Code cleanup to cause Action to re-run. * Stop tests on first failure in UnitTestsParallelizable Updated the `dotnet test` command in `unit-tests.yml` to set the `xunit.stopOnFail` parameter to `true`. This change ensures that test execution halts immediately upon encountering a failure, allowing quicker identification and resolution of issues. Note that this may prevent the full test suite from running in the event of a failure. * Allow all tests to run despite failures in CI Updated `unit-tests.yml` to set `xunit.stopOnFail` to `false` in both `Run UnitTests` and `Run UnitTestsParallelizable` steps. This ensures that the test runner does not stop execution on the first test failure, allowing all tests to complete even if some fail. * Enhance RuneExtensions docs and update user dictionary Updated the `<remarks>` section in `RuneExtensions.GetColumns` to include details about the `wcwidth` implementation and improved readability with `<para>` tags. Added `wcwidth` to the user dictionary in `Terminal.sln.DotSettings` to avoid spelling errors. * Improve XML doc formatting in RuneExtensions.cs Updated the remarks section of the `GetColumns` method in the `RuneExtensions` class to enhance readability by reformatting and properly indenting `<para>` tags. The content remains unchanged, describing the method's implementation via `wcwidth` and its role as a Terminal.Gui extension for `System.Text.Rune`. * Refactor drivers and improve clipboard handling Replaced legacy drivers (`CursesDriver`, `NetDriver`) with `UnixDriver` and `DotNetDriver` across the codebase, including comments, method names, and test cases. Updated documentation and remarks to reflect the new driver names and platforms. Revamped clipboard handling with new platform-specific implementations: `UnixClipboard` for Unix, `MacOSXClipboard` for macOS, and `WSLClipboard` for Linux under WSL. Removed the old `CursesClipboard` and consolidated clipboard logic. Updated test cases to align with the new drivers and clipboard implementations. Improved naming consistency and cleaned up redundant code. Updated the README and documentation to reflect these changes. * Remove `PlatformColor` from `Attribute` struct This commit removes the `PlatformColor` property from the `Attribute` struct, simplifying the codebase by eliminating platform-specific color handling. The following changes were made: - Removed `PlatformColor` from the `Attribute` struct, including its initialization, usage, and related comments. - Updated constructors to no longer initialize or use `PlatformColor`. - Modified `Equals` and `GetHashCode` methods to exclude `PlatformColor`. - Updated `UnixComponentFactory` documentation to remove references to "v2unix." - Renamed `v2TestDriver` to `testDriver` in the `With` class for clarity. - Removed `PlatformColor` references in `DriverAssert` and related error messages. - Deleted test cases in `AttributeTests` that relied on `PlatformColor`. - Cleaned up comments and TODOs related to `PlatformColor` and `UnixDriver`. These changes reflect a shift away from platform-dependent color management, improving code clarity and reducing complexity. Remove `PlatformColor` and simplify `Attribute` logic The `PlatformColor` property has been removed from the `Attribute` struct, along with its associated logic, simplifying the codebase and eliminating platform-specific dependencies. Constructors, equality checks, and hash code generation in `Attribute` have been updated accordingly. The `CurrentAttribute` property in `ConsoleDriver` and `OutputBuffer` has been simplified, removing dependencies on `Application.Driver`. The `MakeColor` method logic has been removed or simplified in related classes. Tests in `AttributeTests` have been refactored to reflect these changes, focusing on `Foreground`, `Background`, and `Style`. Unix-specific logic tied to `PlatformColor` has been eliminated. Additional updates include renaming parameters in the `With` class for clarity, simplifying `DriverAssert` output, and performing minor code cleanups to improve readability and maintainability. * Refactor Terminal.Gui driver architecture for v2 Updated documentation to reflect the new modular driver architecture in Terminal.Gui v2. - Revised `namespace-drivers.md` to include new components (`IConsoleInput`, `IConsoleOutput`, `IInputProcessor`, `IOutputBuffer`, `IWindowSizeMonitor`) and terminal size monitoring. - Replaced "Key Components" with "Architecture Overview" and added details on the **Component Factory** pattern. - Documented the four driver implementations (`DotNetDriver`, `WindowsDriver`, `UnixDriver`, `FakeDriver`) and their platform-specific optimizations. - Added a "Threading Model" section to explain the multi-threaded design for responsive input handling. - Updated examples to demonstrate driver capabilities and explicit driver selection. In `drivers.md`: - Expanded the "Overview" to emphasize the modular, component-based architecture. - Reorganized "Drivers" into "Available Drivers" and added details on `FakeDriver` for unit testing. - Added sections on "Initialization Flow," "Shutdown Flow," and platform-specific driver details. - Provided examples for accessing driver components and creating custom drivers. In `index.md`: - Updated "Cross Platform" feature to reflect new driver names and clarified compatibility with SSH and monochrome terminals. * Moved files around --------- 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 <tig@users.noreply.github.com> Co-authored-by: Thomas Nind <31306100+tznind@users.noreply.github.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

| Terminal.Gui.Drivers | The `Drivers` namespace provides cross-platform terminal abstraction and console driver implementations. |
@Terminal.Gui.Drivers contains the platform abstraction layer that enables Terminal.Gui to run consistently across Windows, macOS, and Linux/Unix systems. This namespace includes console drivers, component factories, input/output processors, and platform-specific optimizations.
The driver system handles low-level terminal operations including cursor management, color support detection, input processing, screen buffer management, and terminal size monitoring. It provides a unified API through IConsoleDriver while accommodating the unique characteristics of different terminal environments.
Architecture Overview
Terminal.Gui v2 uses a modular driver architecture based on the Component Factory pattern:
- IComponentFactory: Factory interface that creates driver-specific components
- ConsoleDriverFacade: Unified facade implementing
IConsoleDriverandIConsoleDriverFacade - IConsoleInput: Reads raw console input events on a separate thread
- IConsoleOutput: Renders the output buffer to the terminal
- IInputProcessor: Translates raw input into Terminal.Gui events (
Key,MouseEventArgs) - IOutputBuffer: Manages the screen buffer and drawing operations
- IWindowSizeMonitor: Detects and reports terminal size changes
Available Drivers
Terminal.Gui provides three console driver implementations optimized for different platforms:
- DotNetDriver (
dotnet,NetComponentFactory) - Cross-platform driver using .NETSystem.ConsoleAPI. Works on all platforms. - WindowsDriver (
windows,WindowsComponentFactory) - Windows-optimized driver using Windows Console APIs for enhanced performance and features. - UnixDriver (
unix,UnixComponentFactory) - Unix/Linux/macOS-optimized driver using platform-specific APIs. - FakeDriver (
fake,FakeComponentFactory) - Mock driver for unit testing.
The appropriate driver is automatically selected based on the platform. Windows defaults to WindowsDriver, while Unix-based systems default to UnixDriver.
Example Usage
// Driver selection is typically automatic
Application.Init();
// Access current driver
IConsoleDriver driver = Application.Driver;
bool supportsColors = driver.SupportsTrueColor;
// Explicitly specify a driver
Application.ForceDriver = "dotnet";
Application.Init();
// Or pass driver name to Init
Application.Init(driverName: "unix");
Threading Model
The driver architecture uses a multi-threaded design:
- Input Thread: Asynchronously reads console input without blocking the UI
- Main UI Thread: Processes events, performs layout, and renders output
This separation ensures responsive input handling even during intensive UI operations.
