Fixes #4497 - makes replacement char conifgurable (#4498)
* Add Glyphs.ReplacementChar config property
Introduced Glyphs.ReplacementChar to allow overriding the Unicode replacement character, defaulting to a space (' '). Updated both config.json and Glyphs.cs with this property, scoped to ThemeScope and documented as an override for Rune.ReplacementChar.
* Standardize to Glyphs.ReplacementChar for wide char invalidation
Replaced all uses of Rune.ReplacementChar.ToString() with Glyphs.ReplacementChar.ToString() in OutputBufferImpl and related tests. This ensures consistent use of the replacement character when invalidating or overwriting wide characters in the output buffer.
* Add configurable wide glyph replacement chars to OutputBuffer
Allows setting custom replacement characters for wide glyphs that cannot fit in the available space via IOutputBuffer.SetReplacementChars. Updated IDriver to expose GetOutputBuffer. All code paths and tests now use the configurable characters, improving testability and flexibility. Tests now use '①' and '②' for clarity instead of the default replacement character.
* Fixed warnings.
* Update IOutputBuffer.cs
Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
* Add tests for wide char clipping edge cases in OutputBuffer
Added three unit tests to OutputBufferWideCharTests.cs to verify and document OutputBufferImpl's behavior when wide (double-width) characters are written at the edges of a clipping region. Tests cover cases where the first or second column of a wide character is outside the clip, as well as when both columns are inside. The tests assert correct use of replacement characters, dirty flags, and column advancement, and document that certain code paths are currently unreachable due to IsValidLocation checks.
* Clarify dead code path with explanatory comments
Added comments to mark a rarely executed code path as dead code, noting it is apparently never called. Referenced the related test scenario AddStr_WideChar_FirstColumnOutsideClip_SecondColumnInside_CurrentBehavior for context. No functional changes were made.
* Remove dead code for wide char partial clip handling
Removed unreachable code that handled the case where the first column of a wide character is outside the clipping region but the second column is inside. This logic was marked as dead code and never called. Now, only the cases where the second column is outside the clip or both columns are in bounds are handled. This simplifies the code and removes unnecessary checks.
* Replaces Glyphs.ReplacementChar with Glyphs.WideGlyphReplacement to clarify its use for clipped wide glyphs. Updates IOutputBuffer to use SetWideGlyphReplacement (single Rune) instead of SetReplacementChars (two Runes). Refactors OutputBufferImpl and all test code to use the new property and method. Removes second-column replacement logic, simplifying the API and improving consistency. Updates comments and test assertions to match the new naming and behavior.
* Update themes in config.json and add new UI Catalog props
Renamed "UI Catalog Theme" to "UI Catalog" and removed the
"Glyphs.ReplacementChar" property. Added several new properties
to the "UI Catalog" theme, including default shadow, highlight
states, button alignment, and separator line style. Also added
"Glyphs.WideGlyphReplacement" to the "Hot Dog Stand" theme.

Fixes #4466 - FillRect Corrupts Wide Characters When Overlapping (#4486)
* Improve wide character handling in output buffer Enhances rendering and state management for wide (double-width) characters. Marks both cells as clean after rendering wide graphemes, ensures replacement cells are marked dirty when partially clipped, and uses Move/AddStr for proper wide character handling and invalidation. * Fix FillRect to handle wide Unicode chars correctly Refactored OutputBufferImpl.FillRect to properly handle wide (double-width) Unicode characters, fixing visual corruption when overwriting CJK text (e.g., with MessageBox borders). Removed the char-based FillRect overload in favor of Rune-based handling. Added helper methods for attribute/dirty management and wide glyph invalidation. Updated OutputBase.Write to always mark adjacent cells dirty for wide chars. Updated tests and added OutputBufferWideCharTests to verify correct behavior in all scenarios. This resolves issue #4466 and ensures robust rendering for wide Unicode text. * Handle wide grapheme clusters in OutputBase rendering Added logic to mark both cells of wide grapheme clusters as clean after rendering, preventing unnecessary redraws. Also included a commented-out preprocessor directive and using statement for potential future use. * Clarify comment for IsDirty logic on wide graphemes Updated the comment explaining why the next cell is marked clean (IsDirty = false) after handling wide graphemes, and added a reference to GitHub issue #4466 for context. * Update test for dirty flag after wide glyph write Adjusted OutputBaseTests to expect column 1's dirty flag to be cleared after writing a wide glyph to column 0, matching current OutputBase.Write behavior. Added clarifying comment and GitHub issue reference. * Update Tests/UnitTestsParallelizable/Drivers/OutputBufferWideCharTests.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Terminal.Gui/Drivers/OutputBufferImpl.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Terminal.Gui/Drivers/OutputBase.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> |

Fixes #4258 - Glyphs drawn at mid-point of wide glyphs don't get drawn with clipping (#4462)
* Enhanced `View.Drawing.cs` with improved comments, a new `DoDrawComplete` method for clip region updates, and clarified terminology. Added detailed remarks for the `OnDrawComplete` method and `DrawComplete` event. Refactored `ViewDrawingClippingTests` to simplify driver setup, use target-typed `new`, and add a new test for wide glyph clipping with bordered subviews. Improved handling of edge cases like empty viewports and nested clips. Added `WideGlyphs.DrawFlow.md` and `ViewDrawingClippingTests.DrawFlow.md` to document the draw flow, clipping behavior, and coordinate systems for both the scenario and the test. Commented out redundant `Driver.Clip` initialization in `ApplicationImpl`. Added a `BUGBUG` comment in `Border` to highlight missing redraw logic for `LineStyle` changes. * Uncomment Driver.Clip initialization in Screen redraw * Fixed it! * Fixes #4258 - Correct wide glyph and border rendering Refactored `OutputBufferImpl.AddStr` to improve handling of wide glyphs: - Wide glyphs now modify only the first column they occupy, leaving the second column untouched. - Removed redundant code that set replacement characters and marked cells as not dirty. - Synchronized cursor updates (`Col` and `Row`) with the buffer lock to prevent race conditions. - Modularized logic with helper methods for better readability and maintainability. Updated `WideGlyphs.cs`: - Removed dashed `BorderStyle` and added border thickness and subview for `arrangeableViewAtEven`. - Removed unused `superView` initialization. Enhanced tests: - Added unit tests to verify correct rendering of borders and content at odd columns overlapping wide glyphs. - Updated existing tests to reflect the new behavior of wide glyph handling. - Introduced `DriverAssert.AssertDriverOutputIs` to validate raw ANSI output. Improved documentation: - Expanded problem description and root cause analysis in `WideGlyphBorderBugFix.md`. - Detailed the fix and its impact, ensuring proper layering of content at any column position. General cleanup: - Removed unused imports and redundant code. - Improved code readability and maintainability. * Code cleanup * Update Tests/UnitTestsParallelizable/ViewBase/Draw/ViewDrawingClippingTests.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Terminal.Gui/Drivers/OutputBufferImpl.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Tests/UnitTestsParallelizable/ViewBase/Draw/ViewDrawingClippingTests.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update Tests/UnitTestsParallelizable/ViewBase/Draw/ViewDrawingClippingTests.cs Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Fixed test slowness problem * Simplified * Rmoved temp .md files * Refactor I/O handling and improve testability Refactored `InputProcessor` and `Output` access by replacing direct property usage with `GetInputProcessor()` and `GetOutput()` methods to enhance encapsulation. Introduced `GetLastOutput()` and `GetLastBuffer()` methods for better debugging and testability. Centralized `StringBuilder` usage in `OutputBase` implementations to ensure consistency. Improved exception handling with clearer messages. Updated tests to align with the refactored structure and added a new test for wide glyph handling. Enhanced ANSI sequence handling and simplified cursor visibility logic to prevent flickering. Standardized method naming for consistency. Cleaned up redundant code and improved documentation for better developer clarity. * Refactored `NetOutput`, `FakeOutput`, `UnixOutput`, and `WindowsOutput` classes to support access to `Output` and added a `IDriver.GetOutput` to acess the `IOutput`. `IOutput` now has a `GetLastOutput` method. Simplified `DriverAssert` logic and enhanced `DriverTests` with a new test for wide glyph clipping across drivers. Performed general cleanup, including removal of unused code, improved formatting, and adoption of modern C# practices. Added `using System.Diagnostics` in `OutputBufferImpl` for debugging. --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> |
