[xwiki-devs] [discussion] Easier way to get configuration into modules.

I was wondering how the current method of configuration came into existence. I googled against the lists and didn't see anything particularly enlightening. IMO the promise of component management is "you ask for it and it's there". The best way I can imagine to ask for a configuration parameter would be: @Requirement("my-module.param") private String configParam = "default value"; If no parameter was defined then "default value" would be the value. Since I imagine making the component manager inject a String and know that it's a configuration parameter would be horrible, I would have chosen a workaround by creating an interface and class which is shared among all consumers of configuration. Something like: public interface ConfigurationString { java.lang.String get(); ConfigurationString default(java.lang.String); } Then to get the configuration parameter you need: @Requirement("my-module.param") private ConfigurationString myParam = ConfigurationString.default("default value"); Since the benefits of writing 2 lines to get a configuration parameter vs. writing 2 classes seem obvious, I assume that this idea was reviewed and cast aside and I was wondering why it was decided that something like this was the wrong approach. If anyone could shed some light on this, I'd appreciate it. Thanks Caleb
