After a lot of searching and banging my head against my keyboard I finally found how to get the database name for my Merb application: Macintosh:ruby-rss-feeds marktucks$ merb -i ... >> repository(:default).adapter => # , @name=:default, @transactions={}> >> repository(:default).adapter.uri => # >> repository(:default).adapter.uri.path => "sample_development.db" # YAY! I'm sure there must be a better way to do this. A Rails::Configuration.database_configuration equivalent? But I just cannot find it. The Merb.config doesn't seem to have a database property / method. You can get stuff like the host ( Merb.config[:host] ). Any suggestions / better solutions are welcome.
