From a2e7798a2d9f05348b4040dd1756983554e4a521 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 15 Dec 2025 10:08:11 +0000 Subject: [PATCH] Comprehensive visual design improvements for TUI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements a complete visual redesign and refactoring to improve consistency, accessibility, and maintainability of the TUI interface. ## New Visual Constants Module - Created trace/tui/visual_constants.py with centralized constants: - Layout: Screen positioning and structure (header, content, footer) - Spacing: Padding and margins (dialogs, horizontal padding) - ColumnWidths: Fixed column widths for lists (tags, IOCs, content) - DialogSize: Standard dialog dimensions (small, medium, large) - Icons: Unicode symbols used throughout UI - Timing: Animation and feedback timing constants ## Color System Improvements - Fixed duplicate color definitions (removed from tui_app.py) - Use ColorPairs constants throughout instead of hardcoded numbers - Separated tag colors from footer colors: - Tags now use magenta (ColorPairs.TAG) instead of yellow - Footers keep yellow (ColorPairs.WARNING) for consistency - Updated TAG_SELECTED to magenta on cyan - All 129+ color_pair() calls now use semantic ColorPairs constants ## Accessibility Enhancements - Added warning icons (⚠) to all IOC displays for visual + color cues - Tag highlighting now uses distinct magenta color - Improved color semantics reduce reliance on color alone - Smart text truncation at word boundaries for better readability ## Layout & Spacing Standardization - Replaced magic numbers with Layout/Spacing constants: - Footer positioning: height - Layout.FOOTER_OFFSET_FROM_BOTTOM - Content area: Layout.CONTENT_START_Y - Truncation: width - Spacing.HORIZONTAL_PADDING - Dialog margins: Spacing.DIALOG_MARGIN - Standardized dialog sizes using DialogSize constants: - Input dialogs: DialogSize.MEDIUM - Multiline dialogs: DialogSize.LARGE - Confirm dialogs: DialogSize.SMALL (with dynamic width) - Settings dialog: DialogSize.MEDIUM ## User Experience Improvements - Enhanced footer command organization with visual grouping: - Used Icons.SEPARATOR_GROUP (│) to group related commands - Example: "[n] Add Note │ [t] Tags [i] IOCs │ [v] View [e] Export" - Smart content truncation (_safe_truncate): - Added word_break parameter (default True) - Breaks at word boundaries when >60% text retained - Maintains Unicode safety while improving readability - Improved empty state messages: - New _draw_empty_state() helper for consistent visual structure - Centered boxes with proper spacing - Clear call-to-action hints - Applied to "No cases found" and "No cases match filter" ## Code Quality & Maintainability - Eliminated hardcoded spacing values throughout 3,468-line file - Used Icons constants for all Unicode symbols (─│┌└◆●○▸⚠⌗◈✓✗?) - Fixed circular import issues with delayed global imports in TUI.__init__ - Updated comments to reflect new ColorPairs constants - Consistent use of f-strings for footer construction ## Visual Consistency - Replaced all "─" literals with Icons.SEPARATOR_H - Standardized truncation widths (width - Spacing.HORIZONTAL_PADDING) - Consistent use of ColumnWidths for tag (30) and IOC (50+2) displays - All dialogs now use standard sizes from visual_constants ## Testing - Verified no syntax errors in all modified files - Confirmed successful module imports - Tested CLI functionality (--help, --list) - Backward compatibility maintained This establishes a strong foundation for future UI enhancements while significantly improving code maintainability and visual consistency. --- trace/tui/rendering/colors.py | 4 +- trace/tui/rendering/text_renderer.py | 6 +- trace/tui/visual_constants.py | 68 +++++ trace/tui_app.py | 421 ++++++++++++++------------- 4 files changed, 298 insertions(+), 201 deletions(-) create mode 100644 trace/tui/visual_constants.py diff --git a/trace/tui/rendering/colors.py b/trace/tui/rendering/colors.py index 3d67ce7..9cbf8c7 100644 --- a/trace/tui/rendering/colors.py +++ b/trace/tui/rendering/colors.py @@ -39,5 +39,5 @@ def init_colors(): curses.init_pair(ColorPairs.TAG, curses.COLOR_MAGENTA, curses.COLOR_BLACK) # IOCs on selected background (red on cyan) curses.init_pair(ColorPairs.IOC_SELECTED, curses.COLOR_RED, curses.COLOR_CYAN) -
