Worked on the helix-editor/helix repository to enhance Zig language support by implementing function call argument matching within the Zig grammar. This involved updating the grammar definitions and refining text object recognition using scm, enabling the editor to more accurately identify and manipulate function call arguments in Zig code. The changes improved code navigation and refactoring capabilities for Zig developers, allowing for more precise code analysis. The work focused on language grammar and text object definition, ensuring that the editor could reliably capture and interact with complex argument structures. No bugs were fixed during this period, with efforts concentrated on feature development.
