Dmitriy Neretin updated LOG4J2-1589: ------------------------------------ Description: There is already a good description what "default value nesting" is: http://logback.qos.ch/manual/configuration.html#nestedSubst (use your browser search function) It is partially implemented in the log4j but it can still be improved. Example from that page above: - "${id:-${userid}}" If the ${id} variable is not set, ${userid} will be used. At the moment it works only if the default value is a concrete value: - ${path:-/only/concrete/path/can/be/used/here} was: There is already a good description what "default value nesting" is: http://logback.qos.ch/manual/configuration.html#nestedSubst (use your browser search function) It is partially implemented in the log4j but it can still be improved.
