com.kroo.epilogue — com.kroo/epilogue 0.6

Simple Clojure logging facade for logging structured data via SLF4J 2+.

*context* clj

Logging context. A structured alternative to the MDC that supports default values and nested contexts. (You can still use the MDC if you like.)

Everything in here in scope of the log statement will be included in the log. Try to use fully qualified keywords to avoid naming conflicts with the core log data.

debug clj macro

(debug msg data & {:keys [cause markers logger-ns]})

Log a message and accompanying data at the :debug logging level.

The log will include anything in com.kroo.epilogue/*context* within the current dynamic scope.

data can be anything that implements the clojure.core.protocols/IKVReduce protocol, but it is recommended to log only maps to avoid confusion.

Options:

• a throwable object as the cause,
• a sequence of SLF4J markers (or strings/keywords), and
• an override logger namespace (logger-ns).

defloggingmacro clj macro

(defloggingmacro name doc-string? attr-map? [params*] body)

(defloggingmacro name doc-string? attr-map? ([params*] body) + attr-map?)

Defines a macro that preserves the original line number and column making it suitable for logging. Otherwise behaves identically to defmacro.

error clj macro

(error msg data & {:keys [cause markers logger-ns]})

Log a message and accompanying data at the :error logging level.

The log will include anything in com.kroo.epilogue/*context* within the current dynamic scope.

data can be anything that implements the clojure.core.protocols/IKVReduce protocol, but it is recommended to log only maps to avoid confusion.

Options:

• a throwable object as the cause,
• a sequence of SLF4J markers (or strings/keywords), and
• an override logger namespace (logger-ns).

info clj macro

(info msg data & {:keys [cause markers logger-ns]})

Log a message and accompanying data at the :info logging level.

The log will include anything in com.kroo.epilogue/*context* within the current dynamic scope.

data can be anything that implements the clojure.core.protocols/IKVReduce protocol, but it is recommended to log only maps to avoid confusion.

Options:

• a throwable object as the cause,
• a sequence of SLF4J markers (or strings/keywords), and
• an override logger namespace (logger-ns).

level? clj

Hashset of accepted levels.

log clj macro

(log level msg data & {:keys [cause markers logger-ns]})

Logs a message and accompanying data at the specified logging level.

The log will include anything in com.kroo.epilogue/*context* within the current dynamic scope.

data can be anything that implements the clojure.core.protocols/IKVReduce protocol, but it is recommended to log only maps to avoid confusion.

Options:

• a throwable object as the cause,
• a sequence of SLF4J markers (or strings/keywords), and
• an override logger namespace (logger-ns).

log* clj

(log* level msg data cause markers logger-ns src)

Primitive logging function for Epilogue.

Do not use this function directly! Use the provided macros instead. Backwards compatibility is not guaranteed for this function.

raise clj macro

(raise msg data & {:keys [level cause markers logger-ns]})

Log and throw. Logs at :error level by default. Constructs and throws a clojure.lang.ExceptionInfo object.

set-default-context! clj

(set-default-context! value)

Set the default value of the logging context.

trace clj macro

(trace msg data & {:keys [cause markers logger-ns]})

Log a message and accompanying data at the :trace logging level.

The log will include anything in com.kroo.epilogue/*context* within the current dynamic scope.

data can be anything that implements the clojure.core.protocols/IKVReduce protocol, but it is recommended to log only maps to avoid confusion.

Options:

• a throwable object as the cause,
• a sequence of SLF4J markers (or strings/keywords), and
• an override logger namespace (logger-ns).

warn clj macro

(warn msg data & {:keys [cause markers logger-ns]})

Log a message and accompanying data at the :warn logging level.

The log will include anything in com.kroo.epilogue/*context* within the current dynamic scope.

data can be anything that implements the clojure.core.protocols/IKVReduce protocol, but it is recommended to log only maps to avoid confusion.

Options:

• a throwable object as the cause,
• a sequence of SLF4J markers (or strings/keywords), and
• an override logger namespace (logger-ns).

with-context clj macro

(with-context extra-context & body)

Merge extra-context onto the current logging *context*, creating a new scope around body.
