This library was renamed to log4cl-extras and moved to:
https://github.com/40ants/log4cl-extras
To turn this handler on, do:
(log4cl-json:setup)Then, somewhere in code:
(log4cl-json:with-fields (:request-id42) (log:info "Processing request") ;; All logging in this call and nested calls will have;; "request-id = 42" field. (process-request))If you want to log unhandled signals' traceback, then do:
(log4cl-json:with-log-unhandled () (foo) (bar)))If some unhandled condition will be signaled in foo or bar, this code will log an error with traceback field like this:
