11 Commits • 2 Features
Jan 1, 2026Month 2026-01: Delivered robust enhancements to SVG rendering and stability in ComPlat/chemotion_ELN, improved backend HTML conversion for Quill deltas, and strengthened molfile handling and reaction condition rendering. Key deliverables include a centralized SVG rendering service with priority-based fallbacks and Rails-based regeneration, a user-initiated SVG refresh workflow, improved text handling and alignment in the Ketcher editor, and strengthened error handling and state management for better user feedback. Fixed molfile conversion failures (blank alias records) and anti-infinite-loop behaviors during graphic updates, improved handling of special characters in reaction conditions, and modernized the backend to use QuillDeltaToHtmlConverter for delta-to-html conversion. These changes reduce user-facing failures, improve rendering reliability, and support more complex molecule data entries.

Oct 1, 2025October 2025 focused on delivering a robust, scalable editor experience and expanding the chemical polymer library while improving reliability. Key work centered on replacing the Ketcherails stack with Ketcher and Indigo, refining Docker, API endpoints, and JS components to enable seamless editing and rendering, and migrating template exports to JSON with a safe fallback. We expanded the polymer library by introducing SVG assets for basic shapes, updating identifiers, and removing deprecated assets to support broader molecule representations. A bug fix ensured Ketcher loads as the default editor when no other editors are configured, preventing blocked editing workflows. Collectively, these efforts improved editing reliability, rendering quality, and asset management, delivering tangible business value by enabling faster workflows, better data interchange, and expanded molecule representations.

Jul 1, 2025July 2025 monthly summary for ComPlat/chemotion_ELN: Addressed a UI initialization race condition to ensure menu action buttons initialize only after user data is available. This involved refactoring the ExportImportButton to manage hasRadar state internally and introducing a listener to UserStore within ReportUtilButton to synchronize menu initialization with user data. No new features shipped this month; the focus was on stability, reliability, and maintainability, resulting in fewer UI inconsistencies and a cleaner initialization flow.
