Re: [xwiki-devs] [Proposal] Introduce LESS in Skin Extensions (SSX)

Hi Guillaume, This is not a domain I know well so maybe what I’ll say is not correct.. :) What about keeping the exact same xobject structure as now but instead of considering the content of the textarea to be plain text we consider it to be wiki syntax that is rendered using our plaintext renderer. This would allow use to use any more (including the {{velocity}} macro, {{include}} macro, etc) but it also allows us to introduce some new {{less}} macro that would preprocess its content and generate CSS. This would also allow us to remove the “parse” option which tells us if we run velocity or not (this is actually bad since we may want to run ruby, python, groovy, etc). WDYT?
