+A little while ago I started using the
+[Awesome window manager](http://awesome.naquadah.org/) again. I've
+started to play some PC games (such as
+[Rogue Legacy](https://ryuslash.org/blog/?p=44)) and have to use some
+more graphical applications again.
+[Stumpwm](http://stumpwm.nongnu.org) just wasn't quite cutting it and
+suddenly it seemed that my workflow didn't quite fit with a
+completely-manual tiling experience.
+
+So now that I'm back with Awesome I wanted to have a count of the
+number of unread articles in Tiny Tiny RSS in my wibox. I already have
+a project named avandu, which is an Emacs interface for Tiny Tiny RSS,
+and for a little while I used that in combination with Emacs' daemon
+mode to get the number of unread RSS items. This halt my Emacs for a
+few seconds every minute, though, so that was unpleasant. It also
+caused a lot of "Connecting to host: ..." messages to appear in my
+Emacs' echo area, which is a little annoying.
+
+So I decided to write a lua module to get this count, since I didn't
+have a lua project yet. That is
+[avandu-lua](https://github.com/ryuslash/avandu-lua). Right now it
+only implements a `login` and `unread` functions, which allow you to
+log-in to get a session key (so you can do other things), and get the
+number of unread articles (what a shock!).
+
+I've written a bit of
+[documentation](http://ryuslash.github.io/avandu-lua/) for it, hosted
+by github. There isn't much to document of course, but I try.
+
+I still need to add tests, but I'm having difficulty deciding on how
+to do this. [busted](http://olivinelabs.com/busted/) looks really
+nice, but their idea of stubs and mocks doesn't seem to be very useful
+if you're testing a function that calls, for example, `http.call`,
+which returns 4 distinct values, not none. I can't decide if I should
+keep looking, (try to) write something or use `_TEST` checks
+everywhere. I'm leaning towards that last one, perhaps I'll add that.
+
+I don't currently have any concrete plans of extending it to have more
+functions than the ones I've added so far, I might do it for fun at
+some point, or if you'd really like to be able to call Tiny Tiny RSS
+from lua let me know and I might put some more effort into it.
+
+It's been nice to work with lua. I don't particularly love the
+language and it certainly doesn't beat Lisp on any front, but it has
+its moments and niceties.
+
+Some things that still need to be done:
+
+- As I said, I need to add tests.
+
+- I think I should try to see if coroutines can be used, it seems to
+  hang Awesome now on occasion.
+
+- Add license info. Yeah I really should almost do this before I do
+  anything else when I start a new project. It's going to be LLGPL in
+  any case.
+
+- Release an actual version. Always installing from just a git
+  checkout can be a little annoying.
