A new logging library for Janet, deforester, introduces structured logging with config validation and interoperability features
Janet developers now have a dedicated logging solution that enforces correctness and supports structured data. The library's config validation and key-renaming features reduce integration friction with existing observability pipelines. This fills a gap in Janet's ecosystem where logging was previously handled through ad-hoc solutions or borrowed from other Lisp dialects
