----------------------------------------
Sure, this is just an idea I had for the future.
> hasFeature(featurestring) API for determining what components are
> installed/enabled

> Key: XWIKI-1986
> URL: http://jira.xwiki.org/jira/browse/XWIKI-1986
> Project: XWiki Platform
> Issue Type: New Feature
> Components: APIs, Core
> Reporter: Sergiu Dumitriu
> Fix For: Future
>
>
> There is no good way of testing for an existing feature. The XWiki object
> provides some methods, like hasVersioning, hasRecycleBin or hasSectionEdit,
> some code tests if a plugin exists, and some code just assumes that a feature
> is always enabled.
> A proper way would be to have a "features" component, which can be used with
> calls like:
> if (Features.hasFeature("versioning"))
> if (Features.get("zipexplorer")) // returns boolean, not the implementation
> itself
> #if($features.charting)
> #if($features.hasFeature("tags", "2.0"))
> I don't know if the Features class should also link to the implementations
> for a feature, or just list the enabled features.
