The payroll application I've been developing for BTree for the last couple months is now getting closer to being ready for actual use. It now boils down to bolstering the manager interface a little, reintegrating reports that were part of an earlier iteration, and taking care of some final first wave feature requests.
This isn't the first internal application I've built based on Camping, but it is definitely closer to being a real application than a quick interface for a command line tool. I might be able to get a beta release out on RubyForge by the middle of August if we get this system in production by the end of the month.
It is a bit specialized, but might benefit from some community insight. We're also going to be using this as the core application for fleshing out the Ruport book, so people will have a nice guide to its internals. Especially interesting is that this application contains most of the camping hacks I've listed on O'Reilly, as well as some interesting report running logic.
Anyway, more to come. The above screenshot is of the current main interface, intentionally Spartan. I'm happy that Mike Milner helped me get it to fit in 800x600, though I thought I'd never have to do that again. Turns out not everyone has quite left the "Giant World" from Super Mario Brothers 3 in terms of screen resolution.
