Copilot AI commented Jan 25, 2026

Modernizes codebase for Python 3.14 compatibility and dearpygui 2.1.1, fixes code quality and security issues, adds comprehensive test coverage, and improves documentation clarity.

Dependencies

  • Add requirements.txt with dearpygui>=2.1.1 (Python 3.14 compatible)
  • Add .gitignore for user-generated artifacts (themes/, Fonts/)

Code Quality & Security

EditThemePlugin:

  • Convert tabs to 4-space indentation (PEP 8)
  • Remove 93+ lines of commented-out code
  • Remove exec() usage - Refactored to use getattr() and direct DearPyGui API calls instead of dynamic string execution
  • Remove string template UI generation - Replaced with proper Python loops and closures
  • Replace unnecessary lambdas with proper methods (_close_edit_window, _show_load_dialog, _show_save_dialog)
  • Replace bare except: with specific exception handlers
  • Add comprehensive docstrings (module, class, method level)

ChooseFontsPlugin:

  • Convert tabs to 4-space indentation (PEP 8)
  • Remove commented-out code
  • Fix font extension matching - Now case-insensitive and properly detects .otf files (was missing dot)
  • Replace unnecessary lambdas with proper methods (_close_font_window, _reset_font_to_default)
  • Replace bare except: with specific exception handlers and logging
  • Add comprehensive docstrings (module, class, method level)

Testing

  • Add comprehensive test suite (test_plugins.py) with 8 unit tests
  • Tests cover plugin initialization, configuration handling, color parsing, font discovery, and error handling
  • All tests passing

Documentation

README.md:

  • Restructure with scannable sections (Features, Requirements, Installation, Usage, Testing, Tips)
  • Add Python version requirements (3.9+ with explicit 3.14 support)
  • Add Testing section with instructions to run tests
  • Fix typos and improve code examples
# Before: unclear usage
with dpg.menu():
    dpg.add_menu_item(label="Show Metrics", callback=lambda:dpg.show_tool(dpg.mvTool_Metrics))
EditThemePlugin()

# After: clear context and structure
with dpg.viewport_menu_bar():
    with dpg.menu(label="Tools"):
        dpg.add_menu_item(label="Show Metrics", callback=lambda: dpg.show_tool(dpg.mvTool_Metrics))
    EditThemePlugin()

No functional changes - existing behavior preserved while improving security, maintainability, and testability.

parse_color_operation executes dynamically generated strings via exec(). Even if the current inputs are intended to be controlled, this makes the code harder to audit, debug, and secure. Refactor to avoid exec by iterating self.theColors and calling DearPyGui APIs via getattr (e.g., resolve the dpg color constant and then call dpg.add_theme_color) or by storing callables instead of string templates.

Refactored completely to remove exec(). Created new methods:

  • _add_theme_colors() - uses getattr() to resolve color constants and direct API calls
  • _save_theme_colors() - iterates colors directly without exec
  • _create_color_editor() - creates widgets with proper callbacks
    The old parse_color_operation method has been removed entirely. Commit: 8bfc968

The UI generation for color editors is built from a large string template (myEditVar) that is later executed indirectly. This approach is very brittle (quoting/escaping issues, static analysis tools can't help) and makes callbacks difficult to reason about. Consider building the widgets in normal Python code inside a loop over self.theColors instead of string templating.

Refactored editTheme to remove string templating. Now builds widgets in a normal Python loop over self.theColors with proper callbacks defined as closures. Much more maintainable and debuggable. Commit: 8bfc968

Font extension matching uses filename.endswith((".ttf", "otf")), which is both slightly imprecise (missing leading dot for otf) and case-sensitive (won't match .TTF/.OTF). Consider normalizing with filename.lower() and checking for (".ttf", ".otf") to avoid missing valid fonts.
