Ceki Gulcu commented on LBCORE-212:
-----------------------------------

Accessing environment variables could probably be quite useful. However, I don't see the point in parametrize the prefix for accessing environment variables. Let's just have it fixed to "env.". The substVars method in the ch.qos.logback.core.util.OptionHelper class seems like the correct location for adding support environment variables.

> It would be very nice to be able to access environment variables in configuration files.
> Maybe like in ant with <property environment="env"/> and then ${env.PATH} to access variable.
> In my use case, it's necessary to get the path to the property file to load...
