That was cool, ikiwiki + copied them over unchanged and the file could be linked to as `\[[foo|foo.xml]]`. -Considering ikiwiki plugins, one idea I have is to make the [[PreProcessorDirective]]s be a plugin. A setting in the config file would enable various plusins, which are perl modules, that each provide one or more preprocessor directives. + I even had the XSL produce an `Edit` link at the top, because I wanted a simple + way for a web user to edit the XML. But I had to hack stuff to make the edit CGI + not say `foo.xml is not an editable page`. -Since preprocessing happens before htmlization but after a page is loaded and linkified, it should be possible to use it to create something like a link map or lists, or a page index. Page inlining and rss generation is already done via preprocessor directives and seems a natureal as a plugin too. + I did that in a kind of slash-and-burn way, and apparently that's the one change + that was uncommitted when I upgraded ikiwiki, so now it's in the same place + as the wikiwyg project. On the bright side, that's a chance to think about how to + do it better. -Note that things like a link map or a broken link list page would need to be updated whenever a set (or all) pages change; the %inlinepages hash already allows for pages to register this, although it might need to be renamed. + Any suggestions for appropriate uses of existing plugins, or the plugin API, + to selectively add to the set of files in the working copy that the edit CGI + will consider editable? --ChapmanFlack 17July2008 + + > It looks like 80% of the job would be accomplished by hooking `htmlize` for + > the `.xml` extension.
