Hi David, The feature your are asking for is definitely possible. If you file a jira issue, I'll happily add it. By the way, the type of variable substitution is supported quite naturally in .groovy configuration files I am currently working on. On 19/05/2010 11:30 AM, David Harrigan wrote:
Hiya,
I love the fact that in logback I can do this for a level:
<logger name="foo" level="${foo.bar.log.level:-debug}"/>
I would love to be able to do the following as well:
<appender-ref ref="${foo.bar.log.appender:-console}"/>
So that I can switch between different appenders during build time. At the moment, If I try that, I get this warning from logback (0.9.21)
11:17:32,676 |-ERROR in ch.qos.logback.core.joran.action.AppenderRefAction - Could not find an appender named [${foo.bar.log.appender:-console}]. Did you define it below in the config file? 11:17:32,676 |-ERROR in ch.qos.logback.core.joran.action.AppenderRefAction - See http://logback.qos.ch/codes.html#appender_order for more details.
Is this achievable?
