Re: [tcf-dev] Phyton integration: dprintf service?
|
Hi,
I am about to merge our code base into the opensource, and we added the
dprintf service and proxy.
As this should occur at the end of next week, I attach the dprintf.py
(to drop in the tcf/services directory) and the DPrintfProxy.py (to
drop in the tcf/services/remote directory).
BTW, the service is not the service implementation, but the service
interface.
Hope this helps

Hi,
I’m currently looking into the TCF Python library. The library contains
Python classes for each of the TCF services. However, I am missing a
Python class covering dprintf service or is it simply covered elsewhere?
cheers,
Conny
