Hi Marius, While this is technically interesting isn't this adding too much complexity for the gain it brings? For ex: * the transformation will run always on all pages for all content, thus adding some small performance lag * it's a little bit too magical maybe I feel your example doesn't clearly show the advantage: * the grouping is saving 1 line of code in the example * the automatic import is saving 4 lines at the expense of clarity Personally I think i'd *much* prefer to hide all this behind a gallery macro: {{gallery}} image:first.png ... image:last.png {{/gallery}} That macro would automatically add the SSX/JSX + class, thus hiding all complexity and implementation details from users. WDYT? Thanks -Vincent On Jan 24, 2011, at 5:08 PM, Marius Dumitru Florea wrote:
Hi devs,
I have this wiki syntax:
----------8<---------- {{velocity output="false"}} $xwiki.ssrx.use('uicomponents/widgets/gallery.css') $xwiki.jsrx.use('uicomponents/widgets/gallery.js') {{/velocity}} (% class="gallery" %)((( image:first.png ... image:last.png ))) ---------->8----------
and I'd like to make the resource import automatic. I think we can achieve this in two steps.
(1) Add a way to group skin extensions. I'd like to be able to write this:
----------8<---------- {{velocity output="false"}} $xwiki.gsx.use('gallery') {{/velocity}} (% class="gallery" %)((( image:first.png ... image:last.png ))) ---------->8----------
(2) Write a rendering transformation that looks for style names (CSS classes) in the content and imports the skin extension group with the same name. This way I'd be able to write just:
----------8<---------- (% class="gallery" %)((( image:first.png ... image:last.png ))) ---------->8----------
Let's consider the technical details now:
(1) I propose we add two XWiki classes:
XWiki.SkinExtension * type (StaticList): jsrx * resource (String): uicomponents/widgets/gallery.js
XWiki.SkinExtensionRole * role (String): gallery
which will be used by a new SkinExtension plugin and component (hint=gsx). The XWiki.SkinExtensionRole objects will be joined with XWiki.SkinExtension objects by document id. In other words, in order to create a skin extension group you have to add a XWiki.SkinExtensionRole object and multiple XWiki.SkinExtension objects to a document.
To make group creation easier for StyleSheetExtension and JavaScriptExtension the new skin extension plugin will include them automatically in the group defined by the XWiki.SkinExtensionRole. In other words if you want to group a JSX and a SSX that are on the same document you just have to add a XWiki.SkinExtensionRole object to that document.
(2) The rendering transformation that will automatically import the skin extension groups based on style names will use the skin extension component defined at step (1). This transformation should be the last one executed.
WDYT? I'd like to implement this ASAP as it doesn't seem to be very complicated.
Thanks, Marius
