bits typedef unable to resolve

[tamilarasub]

Hi,

I am trying to create a typedef for bits, but pyangbind is throwing error. But for other types (i.e. enum.. ) it is working fine. Am I missing anything?

Here is the file "debug-type.yang"
module debug-type {
namespace "http://example.com/debug-type";
prefix "debug-type";
typedef DEBUG_T{
type bits {
bit encode { position 0; }
bit decode { position 1; }
}
}
}

Error:
root@instance-000001a0:~/yang# pyang --plugindir $PYBINDPLUGIN -f pybind -o binding.py debug-type.yang
could not find a match for debug-type:DEBUG_T type -> [u'bits']

The bits YANG type is not currently supported in pyangbind -- there have been a couple of requests - but it hasn't bubbled to the top of things that I have cycles to add right now. I'm happy to review a patch if you would like to contribute support. There was some existing work in #155 which you might be able to base this on.

Thanks for your instant response.
The ticket mentioned by you referring existing work is the current ticket id. Can you please provide me the actual ticket ID?

I believe the correct issue is #68. Is there any way to make pyangbind ignore building code for the bits type instead of it crashing?

It's been around 2 years for this issue, wondering if there is any ongoing work related to support of YANG built-in bits type? I am facing similar issues with converting some Nokia YANG models that use this type:
