cambium.core - TODO and Change Log

TODO

• [TODO] Automatically put ex-data of ExceptionInfo into context
  • Configuration var: cambium.core/*ex-data-key*
  • Default value is nil (any falsy value is a no-op)
  • Value true merges to current context, any other truthy (e.g. :ex-data, [:foo :bar]) considered context key
  • Resolved at compile-time (in the macro)
• [TODO] Key codec support
  • Candidate use-case: EDN
• [TODO] Configurable level for deflevel name prefixes
  • E.g. couchbase.success.*=debug, couchbase.error.*=info for logger METRICS
  • Impl: Auxiliary logger name, e.g. METRICS.couchbase.success for 'enabled?' check
  • Impl: Regular logger name, e.g. METRICS for logging
  • Impl: Prefix->level map must be available before deflevel is eval'ed (compile time)
