org.purefn.kurosawa.log.core — org.purefn/kurosawa.log 2.1.9

Standardized logging configuration.

add-component-appender clj

(add-component-appender appender-kw namespaces filename & {:as rotor-opts})

Generates a function which will add a component specific rotating log appender to a Timbre log configuration.

• appender-kw The keyword identifier for the created component appender.
• namespaces A sequence of string patterns ("com.foo.*" ...) used to direct log messages for matching namespaces to the created appender and away from the :stdout log.
• filename The name of the created log file.

Also accepts the following appender specific options:

• max-size The maximum size a log file can grow (in bytes) before being rotated.
• backlog The number of rotating logs to retain.

Returns a function which takes Timbre log configuration map and returns the modified configuration.

base-config clj

(base-config)

(base-config dir)

Create a base logging configuration for all Kurosawa libraries and apps for use in a production context.

• dir The root logging directory, defaults to prod-dir if not specified.

envmap clj macro

(envmap)

A map of all the symbols and their values currently bound in the environment.

fn-trace clj

(fn-trace fn-name args)

Log the invocation of a function at :trace level along with its arguments.

• fn-name The name of the function being invoked as a keyword.
• args A map of the function argument names (as keyword) and values.

This function should be called (for side-effects only) at the start of the function being traced.

format-msg clj

(format-msg msg params-map)

Generate a formatted string suitable for log messages.

• msg The main log message text.
• params-map A map of information (usually function parameters) to include as part of the formatted message in a standardized form easy for log parsing.

init-dev-logging clj

(init-dev-logging)

(init-dev-logging system)

(init-dev-logging system excluded-comp-keys)

Initialize development logging for a component system.

With no arguments, both the low-level and high-level logging will be sent to the console.

With a single system argument, only high-level logging will be sent to the console. All low-level logging, as defined by (log-namespaces) on the components will be omitted.

If both a system and excluded-comp-keys are given, then some low-level logging will be omitted based on the excluded components. High-level logging will always be included.

• system The initialized component system.
• excluded-comp-keys A sequence of keyword identifiers of components for which low-level logging should be excluded.

This is a side-effecting function that modifies and returns the taoensso.timbre/*config* value.

init-prod-logging clj

(init-prod-logging system)

(init-prod-logging system dir)

Initialize production logging for a component system.

Only high-level component logging will be sent to the console. Per-component low-level logging will be written to separate rolling log files. See individual components for details of the names of these log files. Finally, all logging will be consolidated in a single rolling log file called all.log.

• system The initialized component system.
• dir The root logging directory, defaults to prod-dir if not specified.

This is a side-effecting function that modifies and returns the taoensso.timbre/*config* value.

output-fn clj

(output-fn data)

(output-fn opts data)

Default logging output function.

Use (partial output-fn <opts-map>) to modify default opts.

prod-dir clj

The root directory under which production log files are written.

set-level clj

(set-level level)

Set the default logging level.

• level Possible values: :trace :debug :info :warn :error :fatal :report

Useful shortcut for temporarily changing logging level from the REPL.

system-log-configure clj

(system-log-configure system dir)

Generate a single function which combines all logging configuration for all components in a system.

• system The initialized component system.
• dir The root logging directory.

Returns a function which takes Timbre log configuration map and returns the modified configuration.

system-log-namespaces clj

(system-log-namespaces system)

(system-log-namespaces system comp-keys)

Collect the namespace patterns from the named components of the system.

• system The initialized component system.
• comp-keys The keyword identifiers of selected components, if not specified all components are selected.
