Hi Jerry: Yes, there is some interest assuming you are willing to donate your code under our preferred license which is the LGPL. We would need e-mail stating that from you before we could accept your donation. Furthermore, it's important for you to give us enough detailed information to build the interface and examples for ourselves (see below) since I believe our current Ada expertise is pretty low.

Werner had an excellent question here. We could probably figure out how to build the Ada interface from the general description you give above and reading some of the Ada documentation, but to make it easy for all our developers who have never used Ada (such as me) could you please provide a step by step cookbook of the exact commands (command-line much preferred over GUI commands) we should use to build the interface for those with access to your platform (OS X)? Once we had those, it should be straightforward to integrate those instructions into our CMake build system so that the interface could be easily built on all platforms. >> >> And would it also possible for you to port the examples which you >> can find in the examples directory to ada examples (using the thin >> bindings)? > > I would like to port the examples but I'm a one-person operation so > this would take extra time, especially since I still struggle to > decipher C.

Again, Werner brought up an important point. Showing that the standard set of examples in the language of choice produces the same postscript results as the C examples is an excellent test of that language interface. Thus, an interface is not really considered to be first class until all the standard examples are implemented with results compared with the C results for the standard examples. That said, if your initial donation included just a few of the standard examples, that would encourage us to do the integration work with our CMake build system with the understanding that you would be willing to fill in more standard examples as time permitted. Furthermore, the exposure your interface got with PLplot might inspire others to help you out with that task even if they didn't know Ada to start since it should be straightforward to infer what the source code should be for additional Ada examples once we see the required language syntax in the examples that you supply. I suggest you use the f95 examples as the template for your initial subset of the standard examples in ada. That interface (like most of our high-level interfaces) has all redundant dimension information dropped so that sounds most compatible with your "thick" ada interface to PLplot.
