Jun 1, 2025June 2025 monthly summary for kleros/kleros-v2 focusing on delivered features, bug fixes, and impact. Key features delivered: - Mustache Hex Lambda: Added a new hex lambda to the Mustache templating engine within the kleros-sdk. This enables hexadecimal formatting with a 0x prefix in dispute details, improving data presentation in templates and enabling consistent hex formatting for on-chain references. (Commit: 2925a4e93b42aa527a587786cc5a7e13d50c198a) Major bugs fixed: - Mustache Template Lambda Ordering and Type Safety Fix: Refactored the order of spread syntax in populateTemplate so lambdas are applied before data, and tightened type safety for the hex lambda. (Commit: 33a47a9e4d511634c13b043633b810c6fffa8c1c) Overall impact and accomplishments: - Improved data formatting and rendering reliability for dispute details, delivering a more polished user experience and reducing template-related errors in production. - Strengthened templating pipeline with safer lambda usage and clearer data flow, enabling easier future enhancements. Technologies/skills demonstrated: - TypeScript, Mustache templating integration, lambda functions, template rendering pipeline, commit-driven development.
