PROFILE

Morisa Manzella

Worked on the Shopify/theme-tools repository to improve the Liquid HTML parser by focusing on code hygiene and risk reduction. Addressed maintenance concerns by removing the unused '@prompt' node, which involved updating the parser’s grammar, adjusting AST node representations, and refining type definitions to reflect the streamlined codebase. Also eliminated related tests, aligning the test suite with the current feature set and improving continuous integration efficiency. Utilized JavaScript, TypeScript, and parser development skills to ensure the parser’s functionality remained intact for end users while reducing the surface area for potential regressions and simplifying ongoing maintenance of the codebase.

April 2025 (2025-04): Shopify/theme-tools focused on code hygiene and risk reduction in the Liquid HTML parser. Completed the dead code cleanup by removing the unused '@prompt' node, including grammar updates, adjustments to AST node representations and type definitions, and the removal of related tests. This reduces parser surface area, shortens test cycles, and lowers risk of regressions while preserving existing functionality for end users. Commit reference available for traceability: 7ff54f02004ec6ecffe30123946fceed37130aaa (Delete dead code #886).
