JSPWIKI-120: rename + extract interface from GroupManager
> Separate rendering engine from core
> -----------------------------------
>
> Key: JSPWIKI-120
> URL: https://issues.apache.org/jira/browse/JSPWIKI-120
> Project: JSPWiki
> Issue Type: New Feature
> Components: Core & storage
> Reporter: Janne Jalkanen
> Priority: Major
> Fix For: 3.0
>
>
> Quite a few people have shown up recently on the mailing list and have
> expressed a wish to separate the rendering engine from the core itself, so
> that they wouldn't need so much baggage with the engine.
> Unfortunately, this is quite difficult, as the rendering engine does rely on
> quite a few bits from the WikiEngine instance, for example URL generation and
> checking whether a page/attachment exists or not, as well as settings.
> However, these things could be enumerated and isolated to a RenderingContext
> interface. Then, anyone who would like to get their own engine would need to
> implement this interface.
> It may mean that WikiEngine and WikiContext might need to become interfaces
> as well. However, that might not be such a bad thing, as it would give a
> more stable developer API. Then we would have a three-layered architecture,
> where one layer (WikiEngine) takes care of static stuff, WikiContext contains
> per-request data, and RenderingContext provides the bits and pieces which are
> part of HTML generation.
> At any rate, this requires more thinking. Probably not going to happen
> before 3.0 anyway.
