pyang and JNC integration - ietf-netconf

Question

I'm trying to integrate JNC and Pyang. As the jnc steps describes I have copied jnc.py under PYANG_HOME/pyang/plugins. I try to generate the java classes for simple.yang under $JNC_HOME/examples/yang using the command
pyang -f jnc --jnc-output src/gen/simple yang/simple.yang
facing the following error,
Traceback (most recent call last):
File "D:/tools/pyang-master/bin/pyang", line 434, in <module>

File "D:/tools/pyang-master/bin/pyang", line 408, in run

if module_stmt in (imported + included):
TypeError: unsupported operand type(s) for +: 'map' and 'map'
Anyone faced this kind of issue. please let me know how to fix this.

Answer 1

Problem is with map implementation:
map in Python-3 returns an iterator, while map in Python 2 returns a list:
Python 2:
>>> type(map(abs, [43, -12, 13, -14]))
<type 'list'>
Python 3:
>>> type(map(abs, [99, -52, 32, -34, 13]))
<class 'map'>
You can edit file jnc.py and change code as below:
for (module_stmt, rev) in self.ctx.modules:
if module_stmt in (imported + included):
module_set.add(self.ctx.modules[(module_stmt, rev)])
for (module_stmt, rev) in self.ctx.modules:
if module_stmt in (included):
module_set.add(self.ctx.modules[(module_stmt, rev)])
if module_stmt in (imported):
module_set.add(self.ctx.modules[(module_stmt, rev)])
