Instance-identifier defined in ietf-netconf but not mapped in pyangbind

[sanchayanghosh]

What is the issue?

instance-identifier not being mapped. #123 was opened to address this issue, but got closed due to inactivity. So opening this issue because I don't know how to reopen that issue.

Elaborate on the issue?

I have created a test yang with instance-identifier defined as per RFC 6020

aeroplane.yang

module aeroplane {
    yang-version 1.1;
    namespace "urn:aeroplanetypes:test";
    prefix "test";
    revision 2024-08-02;
    container aeroplane {
        description "Its an aeroplane";
        leaf identityaero {
            type instance-identifier;
        }
    }

}

I use this script to compile this yang to a py module using pyangbind
run_pyang.sh

#!/bin/bash
export PYBINDPLUGIN=`/usr/bin/env python -c \
'import pyangbind; import os; print ("{}/plugin".format(os.path.dirname(pyangbind.__file__)))'`
echo $PYBINDPLUGIN


pyang --plugindir $PYBINDPLUGIN -f pybind -o $2 $1

I run above script and get this error

./run_pyang.sh build/aeroplane.py yang_values/aeroplane.yang 2>&1 | pbcopy
/mnt/5a257e09-2112-4140-b6d0-529977714705/yang/.venv/lib/python3.12/site-packages/pyangbind/plugin

False

In #123 @robshakir had asked for a patch with what the value instance-identifier should be mapped to. Whoever is the maintainer now, I can submit a patch taking a look at the netconf-rfc for the right mapping.

I will be creating a PR for this. Thanks for all those who review it.

[sanchayanghosh]

Very sorry for the delay. I ended up having a lot of work in a few projects. I have written a draft PR. I wanted to ask if I also need to write custom logic to check that the value passed is a valid xpath? Instance identifier sets and gets the xpath itself.
