[jira] [Updated] (LOG4J2-1589) Value nesting during property
substitution
[ https://issues.apache.org/jira/browse/LOG4J2-1589?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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}
