Nov 1, 2024November 2024 — dream-num/univer: Architectural and stability improvements across the Univer formula engine and spreadsheet tooling, with a clear focus on business value, reliability, and developer experience. Highlights include modular dependency injection and robust UI initialization for the formula engine, stronger cross-sheet handling and numeric parsing, and targeted stability fixes, complemented by enhanced testing and documentation. Key areas delivered: - Univer Formula Engine: Dependency Injection and UI Initialization Enhancements — introduced explicit interfaces for core services, stabilized controller and toolbar initialization, and refined progress and data model behavior to improve modularity and robustness in rendering and calculations. - Spreadsheet Formula Parsing and Cross-Sheet Reference Robustness — hardened numeric parsing, ensured correct cross-sheet updates when rows/columns are edited, and normalized sheet names to prevent regressions; preserved non-numeric strings faithfully. - Range Tools Stability: Avoid Stack Overflow — resolved a stack overflow issue in large-range merges by replacing spread syntax with concat for safer merges. - Documentation and Testing Improvements — updated Zen-Editor links across locales and added end-to-end tests for sheet facade hooks, while refactoring internal services and facade definitions to support robust testing. Business impact: Improved reliability and correctness of formula evaluation across sheets, reduced regression risk on structural edits, and enhanced developer productivity through clearer interfaces, stronger test coverage, and up-to-date documentation. Technologies/skills demonstrated: TypeScript/JavaScript architectural patterns, dependency injection, UI initialization sequencing, robust data parsing and normalization, large-scale refactoring for stability, end-to-end testing, and documentation maintenance.
