I have only tried it in a very minimal way, just to see that it did
basically what was advertised, but you might be interested in this.
There's a Ruby library that allows you to do things like:
h = Py::Httplib::HTTP.new(host)
Ie, the "require 'python'" makes pulling in Python libraries
as simple as ...
which is almost as easy as doing it in Python.
Similarly, referencing elements of such a library simply
requires prefixing them with "Py::". Once you have a
handle to a Python object, you call it the same way you
would in Python. I don't think one could make it much simpler.
So, to some extent, it's possible to avoid reinventing the
wheel. How well this works, I can't say, just that the
examples I played with worked as advertised.
Obviously, there's some overhead, in that it's running a copy
of the Python interpreter to execute the Python code, but so
long as the work the library is doing for one is larger than
the actual overhead of the call to it, that shouldn't be a
