Add FloatingWindow class for overlay UI elements#184
Conversation
Implement FloatingWindow as a Window subclass using Curses::Pad for overlay rendering capabilities. This enables popup menus, tooltips, and other temporary UI elements without disrupting the window layout. Features: - Window subclass with dedicated buffer per instance - Curses::Pad for overlay rendering on top of existing windows - Factory methods: at_cursor, centered - Face support for customizable colors and styling - Cursor position management (focus stays in editing window) - Auto-cleanup of generated buffers Implementation: - lib/textbringer/floating_window.rb: Core FloatingWindow class (250 lines) - lib/textbringer/faces/basic.rb: Define :floating_window face - lib/textbringer/window.rb: Integrate floating window redisplay - lib/textbringer.rb: Add require for floating_window - test/textbringer/test_floating_window.rb: 24 tests, 68 assertions Test results: 442 tests, 1946 assertions, 100% pass, 95.03% coverage 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Implement FakeCursesPad in test_helper.rb to enable proper testing of FloatingWindow which uses Curses::Pad instead of Curses::Window. FakeCursesPad provides: - Basic pad methods: erase, setpos, addstr - Attribute methods: attron, attroff, attrset - Refresh method: noutrefresh (no-op for testing) - method_missing for unimplemented methods This follows the same pattern as FakeCursesWindow and ensures FloatingWindow tests can run without requiring an actual terminal. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Pull request overview
This PR introduces a FloatingWindow class that extends Window to support overlay UI elements like popup menus and tooltips. The implementation uses Curses::Pad for rendering on top of existing windows without disrupting the layout.
Changes:
- New FloatingWindow class with factory methods for positioning (at_cursor, centered)
- Face support for customizable styling
- Window class integration for floating window redisplay
- Comprehensive test suite with 24 tests and 68 assertions

The calculation of space_above is incorrect. Currently it computes cursor_y - window.y which equals window.cursor.y, giving the cursor position within the window rather than the actual screen space above the cursor. It should be just cursor_y to get the screen space available above the cursor position.
| space_above = cursor_y - window.y | |
| space_above = cursor_y |
- Add current_line_face parameter to highlight the line containing point - Fix resource leak in resize method (close old_window) - Fix space_above calculation in calculate_cursor_position Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
