[ros-users] dynamic_reconfigure server in Python?

[Patrick Bouffard]

Thanks Blaise. That will probably help, though I'm looking for an
example in Python.

Specifically, I'm stuck as to how to specify the 'type' argument when
instantiating a dynamic_reconfigure.server.Server:

class Server(object):
    def __init__(self, type, callback): <== what is type?
...

I can see that, for C++, there is a build step that generates a C++
class from the .cfg file, i.e. if I have Test.cfg it generates a
TestConfig class. And as shown in the example you point to, that is
the type that is specified in the templated constructor for the
server. So I imagine there is some equivalent to this in python that
probably doesn't involve any code generation, since the .cfg file
itself is really a python script. But I'm at a loss to figure out
exactly how to proceed. I imagine it should look something like:

import dynamic_reconfigure
from ____.___ import ____
...
myserver = dynamic_reconfigure.server.Server(____, my_callback)

Any guesses how I should fill in the blanks? :)
