Joseph is a Ruby library that interfaces with Libgerbv, an open source CAM tool for processing Gerber files. It allows incorporating Gerber parsing, editing, exporting, and rendering into other programs without needing a UI. The document demonstrates Joseph's usage and highlights that it is easy to install, has no UI requirement, is battle proven, and high performance. It encourages using, spreading the word about, and contributing to Joseph's development and testing.

2. Why?

3. Why?
CAD applications (e.g. KiCad) are used for tasks they are not made for
● Panelization of PCBs and / or Stencil data
● Manufacturing support, e.g. V-Cuts
● Drills / Fiducials off the actual PCB
● Analyzing drill count

4. Reason
We’re missing an open source CAM tool for
Gerber files!

5. There is something out there but it’s way out in the distance...
GerbV (libgerbv)
Gerbv is split into a core functional library and a GUI portion. Developers wishing to incorporate Gerber
parsing/editing/exporting/rendering into other programs are welcome to use libgerbv.

7. Benefits of Joseph
● Easy to install and use
● No UI necessary (can be used in continuous integration)
● Battle proven
● High performance

8. That’s it folks!

9. Gerbv developers… (Sergey Alyoshin?)
Please update Gerbv packages!

10. Current situation
● Used in production within our company AISLER for various Gerber related tasks
● Features are “as required by the company’s needs”
● Coverage of Libgerbv calls is about 80% (but that’s worthless anyway)
● Test suite is mainly integration based
● Split out of a larger library a few days ago

11. I want to support Joseph, how do I?
● Spread the word and use it!
● Report issues and feature requests on Github
If you’re a software developer or want to become one
● Add more high-level API suitable for EE use
● Extend RSpec test suite
● Add new features (like font / text support)
