Stylesheets in Pier demo

(repost) Perhaps you would be interested to take a look at the first shot of my approach to handling styles entirely within pier. As a first go, it may have some rough edges but let me know what you think of the concept. http://create.seasidehosting.st you may login as per normal to have a look around. ---- 1. I moved the layout from "/environment" to "/environment/layout" which frees up "/environment" for some contextual information, instructions and presentation of environment features, which now include a stylesheet, and color tables. (I think that a user manager should go in here also, so as to avoid cluttering up the rest of the interface. A save image (copy) action button might be a useful administrative tool which could go in here too) 2. I wrote a visitor that collects the text in a page, includes the content text of any embedded pages, and inserts a url for any embedded images. This is used beginning at "/environment/stylesheet/main", and the visitor assembles a stylesheet. Embedded text pages can be used as variables (see see "/environment/colors" ). 3. The stylesheet is collated into the htmlRoot by PRPierFrame, which currently has things like environmentSelector, layoutSelector, stylePageSelector, hard coded. The plan is to take all of this configuration and refactor it into a decorator (PRManager and sons). The PRPierDefaultEnvironmentManager decorator is applied to the root page by default, and it uses this to tell where to find its environment (because when localized it might be called something else). 4. (planned) PRManagers may be applied to any page in the wiki tree to override styles and layouts for siblings. Sibling environments should only need to modify bits of the environment since they are inherited from the parent environment. PRManagers will be able to do lots of other useful functions, such as maintaining an alias list, colour -> color, for example, or managing the "new page as sibling", "new page as child" policies. I haven't made any effort to present the stylesheet correctly, at the moment it is at the mercy of wiki syntax when displayed. (hence comments are spread across two lines to avoid double stars /*not a link*/ being interpreted as links) I have a notion of micro content (which I implemented in a thing called tiddlypom) where sub parts of a page are marked and tagged. They may even use different parsers. With this in place, the stylesheet information could be a subpart of a page (what I call a "tiddle") with its own non-wiki-syntax parser. And colors could be listed in a single page because links such as "/environment/colors//broken" would resolve to a marked "tiddle" part of the "/environment/colors" page. I am really impressed with seaside and pier too now I have had a chance to get my teeth into it. best regards Keith ___________________________________________________________ The all-new Yahoo!
