I’ve released a new version of Scrumptious. Main change is it now supports Open ID. You can click a “login” link to comment by Open ID. It’s optional by default, though a Scrumptious site operator could easily make it mandatory for read, write, or both by just changing a couple of words in the “policy” config files. Similar to other CMSs like WordPress, non logged in users can indicate their name and URL when they submit a comment.
There are also UI enhancements - the design is cleaner and looks closer to the original original TiddlyWiki comments plugin. Interestingly, I retained almost identical markup, so I was able to cut-and-paste the original CSS for the comments plugin and it mostly worked. I also now include the default TiddlyWiki stylesheets as well. It’s not just look-and-feel which is closer to the original plugin, but the content - you now have info like modifier, modified date, and a permalink available.
I also added something I always wanted to add on the original plugin, which is some animation, e.g. when you add a new reply, the page scrolls to that reply, and a yellow fade effect highlights it. This is a genuinely useful feature as I was finding it difficult to see which reply I’d just added, when there are a lot of comments around.
I’ve also begun work on a Comments Report showing recent comments. Obvious related enhancement is to take the TiddlyWeb Atom plugin and make a comments feed.
Right now, all this is only tested on Firefox (the original was tested on all browsers, at least the full website view); my next priority is to work on browser compatibility, and after that, extract a modular JQuery comments plugin.
Regarding the implementation, TiddlyWeb ships with Open ID by default (Open ID is one of two default challengers, the other being the usual simple user-pass key pair config). The most challenging thing here was getting the UI right for both anonymous users and logged in users, as well as handling a redirect in the popup after a successful login; but at the back end, Open ID “just works”.
In summary, I added Open ID support as follows:
- Add a "login" link to the TiddlyWeb OpenID challenger UI, using a "target" attribute so the challenger opens in a popup.
- The challenger URL in that link also contains a redirect param, which I redirected to a new static page. This static page shows the user their login ID (by inspecting the "tiddlyweb_user" cookie value), calls a callback "onLogin" method on the original page, and closes itself.
PS I discovered late in the day (literally) that TiddlyWeb lets the client specify whatever modifier they want
