I use YAML with custom constructors: http://hg.mperillo.ath.cx/wsgix/file/tip/wsgix/conf/loader.py There is a middleware: http://hg.mperillo.ath.cx/wsgix/file/tip/wsgix/conf/middleware.py that reads a list of configuration files to load from the WSGI environ (I set this in the Nginx mod_wsgi) configuration, and merge all the configuration in the WSGI environ. Using custom YAML constructors it is possible to do something like: http://hg.mperillo.ath.cx/wsgix/examples/file/tip/dbview/settings.yml It is also possible to configure the global python logging, create temporary files and so on. > Thanks, > -- Alex > Manlio _______________________________________________ Web-SIG mailing list Web-SIG@python.org Web SIG: http://www.python.org/sigs/web-sig Unsubscribe: http://mail.python.org/mailman/options/web-sig/archive%40mail-archive.com
