Rubyfocus is a pure ruby bridge to OmniFocus. It’s something I’ve been working on for a while, and I’m finally able to release a version that, at the very least, functions without crashing (as far as I can tell) anywhere along the way.
Rubyfocus started as a natural offshoot of a previous project, JROFBridge. JROFBridge is an objective-C/Cocoa library that accesses OmniFocus through ScriptingBridge, collects data on projects, tasks and folders, and outputs it to an SQLite database. It’s a handy way of collecting everything you need to know about an OmniFocus document, working through OmniFocus itself. I used it for a web-based Kanban frontend to OmniFocus, which let me view all my projects (and my current workload) at a glance.
