Tumblelog design

Yay, found time to give my tumble log a little theme upgrade. And while I'm doing that, I thought I could write down some thoughts on the current design. I might even update it later.

In contrast to this Coleslaw blog I've made a small static renderer to HTML/ATOM for the tumble log, so the interface is mostly console vim to text file with S-expressions. Since at the moment there is only a single file I might just show the syntax for that one:

;; -*- mode: lisp; coding: utf-8-unix; -*-

Clearly this would be viable to store in a DBMS as well, but this is good enough as they say. Featuring PURI, a few other syntax extensions, (my fork of) CL-WHO (for XML extensions) and CL-MARKDOWN for text rendering. The Markdown rendering could use a few fixes for edge cases, but in general it works pretty well and fast. Tags are also written to separate files (both HTML and ATOM), so readers could actually restrict themselves to a few subsets, even though it's not a by any stretch a full-fledged query system.

Still, by rendering to static files a lot of problems go away and the whole site can be served very efficiently via a small web server (I'm leaving Hunchentoot/teepeedee2 for more involved projects).
