Hi,

I want to use libnetconf as a netconf server and client lib for my application in device.

I have YANG modules available for my application. But in the device pyang is not present. Do I need PYANG in my device also to use libnetconf.


When i am using lnctool to generate .yin file for my module, it is giving

ambika@ambika-VirtualBox:~$ lnctool --model /home/ambika/modules/mo...@2013-03-21.yang convert
Traceback (most recent call last):
File "/usr/local/bin/lnctool", line 428, in <module>
model = convert_to_yin(args.model.name, args.search_path)
File "/usr/local/bin/lnctool", line 63, in convert_to_yin
yin_data = subprocess.check_output(['pyang', '-p', search_path, '-f', 'yin', input_file_name])
File "/usr/lib/python2.7/subprocess.py", line 537, in check_output
process = Popen(stdout=PIPE, *popenargs, **kwargs)
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

Hi Ambika,
pyang is needed for development of a transAPI module. It's not needed
for running compiled application. pyang is needed to convert yang data
model into formats used by libnetconf but libnetconf doesn't use pyang
runtime.

Hi Radek,

Is there any way to automatically generate "path file" used for TransAPI code generation ? Because if lots of TransaAPI modules need to be written, it takes significant manual effort to write the path file.

Hi Partha,

no, the "path file" is input for lnctool. I'm open to new ideas, but I can hardly imagine how to automatically recognise which path of the data tree is important and should be implemented by the developer.

Regards,
Radek
