Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the defcon app by introducing comprehensive support for 2x displays and improving the underlying code structure. The changes simplify how DEFCON levels are extracted from HTML content and modernize the rendering pipeline, making the application more adaptable to different display resolutions and easier to maintain.

Highlights

• 2x Display Support: Implemented support for 2x displays, allowing the app to render at higher resolutions with appropriate scaling for fonts and elements.
• Simplified HTML Parsing: Refactored the HTML parsing logic by leveraging the html.star module, which significantly simplifies the extraction of the DEFCON level from the webpage.
• Rendering Logic Refinement: Streamlined the rendering functions (main, render_defcon_display, get_defcon_display) to improve code readability, maintainability, and to properly accommodate 2x scaling.

Changelog

• apps/defcon/defcon.star
  • Imported html and canvas modules to facilitate HTML parsing and 2x display detection.
  • Updated CACHE_TTL_SECONDS to a more explicit calculation for clarity.
  • Introduced SCALE and dynamically selected FONT based on canvas.is2x() for responsive rendering.
  • Removed deprecated trim_left, trim_right, and extract_defcon_level utility functions.
  • Consolidated HTTP request and HTML parsing into a new get_defcon_level function using html.star.
  • Modified the main function to utilize the new get_defcon_level and updated the root rendering structure to support dynamic sizing and spacing.
  • Added a new helper function render_box to encapsulate box rendering logic with 2x scaling considerations.
  • Rewrote get_defcon_display to use render_box and implement a more robust rendering strategy for the DEFCON level indicators, including handling animation and static display.
  • Adjusted display_instructions to dynamically set width and font based on 2x support and updated marquee delays.
• apps/defcon/manifest.yaml
  • Added supports2x: true to the manifest, indicating compatibility with 2x displays.

Code Review

This pull request adds 2x support and refactors HTML parsing. However, there is a rendering issue in the instructions screen due to incorrect marquee offset calculations and missing font properties. A comment with a suggested fix has been added. Additionally, the app is missing the required preview images (defcon.webp and defcon@2x.webp) as specified in the repository's style guide (lines 22-24).
