All GitHub trails
  1. Building a more accessible GitHub CLIThis post details significant improvements for users relying on screen readers, high contrast, and customizable color options. It covers the adoption of the `charmbracelet/huh` prompting library for better screen reader interaction, replacing visual spinners with static text progress indicators, and aligning color palettes to 4-bit ANSI colors to respect terminal preferences. The team also plans to enable extension authors to implement similar accessibility improvements and explore table formatting customization.
  2. Accessibility considerations behind code search and code viewThis post details the implementation of accessibility improvements for GitHub's code search and code view. It covers process improvements through external auditing, design reviews, and office hours. Specific implementation details include managing focus after sort order changes in code search, announcing search results for screen reader users, the development of an open-source TreeView component for file tree navigation, and rethinking code structure in the DOM to support keyboard navigation and screen readers. It also addresses challenges with virtualization and symbol panel navigation, proposing a solution modeled after the Monaco editor using `contentEditable` divs.
