[xwiki-devs] [Proposal] Refactoring registration page and add some apis

Hello all, I am working on refactoring the registration page. I have a mockup which uses the view action so that the register action is not needed, I'm not sure if it makes more sense to remain a template or be moved to an application, any thoughts on this? There are a few apis which would make this job a lot easier and cleaner. I would like to provide Velocity access to ConfigurationSource. There would be a configuration parameter which a list of configuration parameters that Velocity is allowed to read. I think it makes the most sense to add a VelocityContextInitializer to the default Configuration implementation which injects a ConfigurationSource wrapper. Perhaps name it $configurationsource Currently (in my mockup) there is no way to tell the guest who is registering that their chosen user name is taken or is invalid if the captcha is wrong, this is because the username is checked by $xwiki.createUser after the captcha is verified. If we add the following two apis then all of the checking can be done on the Velocity side. $xwiki.isUsernameAvailable(String name) This will check if the name is the name of the superuser then check if a document exists by that name. Should I be using an EntityReference? I lean toward string because that is what the user types in. $util.compilePattern(String regex) Returns a Pattern or null if regex is invalid because Perl5Util methods all throw exceptions which Velocity can't catch. I appreciate any thoughts/advice you have to offer. Thanks, Caleb
