Is there any way to substitute environment variables in playframework's application.conf?

Question

Is there any way to use environment variables in the play! application.conf file? Something like this:

%prod.db.url=${env.DATABASE_JDBC_URL}
%prod.db.driver=org.

I have the same problem. My solution :

• let application.conf with only properties for local development and store it in a VCS (SVN, Git, ...) for your dev team
• add a line in the application.conf file : "@include.prod=prod.conf"
• the file prod.conf contains only %prod.* properties
• create the file prod.conf directly on prod server (or store it in a different VCS than your application, where only allowed people can read/write it)

It works fine for me.

It just adds a message for the dev team when the application starts :

ex: 20 mai 2011 21:09:16 play.Logger warn ATTENTION: Missing include: @include.prod

Really not a problem. Just inform your dev team that this message is not a problem and to not delete the "@include.prod" line in application.conf

Hope it helps
