Worked on the helix-editor/helix repository to deliver enhanced Unison language grammar and editor support, focusing on improving the accuracy and usability of Unison code editing. Developed and integrated updated syntax highlighting, refined indentation rules, and new text object definitions to align the editor’s behavior with Unison’s language constructs. Leveraged skills in code parsing, language grammar development, and syntax highlighting, primarily using scm and toml. These changes improved parsing accuracy and code display, reducing editing errors and cognitive load for Unison developers. The work established a stronger foundation for future Unison support and contributed to more robust parser and UI integration.
