[logback-user] Is there System properties configuration?

[Laedret]

Hi,

I'd like to "ask" for this feature. For two reasons, the first being easier
migration from log4j. The second because the classpath hack is rather ugly.
It's too easy to have someone sneak in a logback.xml or loback-test.xml
somewhere in the classpath by mistake or on purpose as part of some library
and suddenly there's a world of pain trying to work our what jar file
amongst hundreds that contains it. 

It's a way of telling the application to use a specific file and no other
file and there's no questions about which file was used. Personally I prefer
being explicit about this, because of experience with log4j config's
littered around various libraries.

I think your point is valid that keeping things simple makes learning and
using logback simpler but having the option to specify the name of the file
adds flexibility without any real cost in complexity.


The way logback looks for the test config before the regular config is
brilliant for development purposes and the case where an application only
needs one production config, but at least in our production environment we
deploy the same application in various enviroments and they all need
different log configs - which we currently solved by having more than one
log config as part of the application bundle and specifiying the path/name
as a system property.

Cheers,
Henric
