iscpy python3 library. Read and write to ISC-styled configuration file (DHCP, BIND)

python3-iscpy

iscpy Python3 library. Reads and writes ISC-syled configuration files such as ISC BIND8/BIND9 and ISC-DHCP server/client. Additional features such as adding zone and write to file

Usage

ParseISCString(isc_string)

Returns parsed bind config file in python dictionary format(ISC dictionary) and keys without childkeys e.g. include

AddZone(json_zone, isc_dict)

Adding zone. Input is in json string. Returns ISC dictionary with added zone. This method doesn't include writing to output file

WriteToFile(isc_dict, isc_specialkeys, filename)

Write ISC dictionary to a file

iscpy's Issues

iscpy_core and submodule 'dns'

During the port from Python2 to Python3 using futurize utitlity (from future Python package, I got the following error after build and install:

Assumes python3 selected on Debian (via update-alternatives utility):

git clone https://github.com/egberts/iscpy
cd iscpy
python setup.py build
python setup.py install --user
cd test
~/iscpy$ python named_importer_lib_regtest.py 

Result is:

Traceback (most recent call last):
  File "named_importer_lib_regtest.py", line 46, in <module>
    import iscpy
  File "/home/steve/.local/lib/python3.5/site-packages/iscpy-1.8-py3.5.egg/iscpy/__init__.py", line 38, in <module>
    from iscpy_core.core import *
ImportError: No module named 'iscpy_core'

File in question is: iscpy/init.py
Module in question is: iscpy/iscpy/iscpy_core
Original Python2 statement in question:

from iscpy_core.core import *
import iscpy_dns.named_importer_lib as dns

New Python3 statement (as futurize recommended)

from __future__ import absolute_import
from .iscpy_core.core import *
from . import iscpy_dns.named_importer_lib as dns

Parser returns last 2 entries

I have dhcp_static.conf which has 118 IP assigments and i want to parse with python. This file will be included in dhcpd.conf file.

dhcp_static.conf

host host_0 {
  hardware ethernet 18:DB:F2:5E:00:00;
  fixed-address 10.12.24.81;
}
host host_1 {
  hardware ethernet D4:AE:52:BD:00:00;
  fixed-address 10.12.42.1;
}

... (many more) ...

host host_118 {
  hardware ethernet DC:A6:32:B7:00:00;
  fixed-address 10.12.67.22;
}

assigments.py (my script)

import os, types, iscpy

NAMED_FILE = 'dhcp_static.conf'

named_file = open(NAMED_FILE).read()
# print("named_file:",named_file)

isc_arr = iscpy.ParseISCString(named_file)
print(isc_arr)

Result:

$ python assigments.py 
[{'host host_117': {'hardware': 'ethernet 18:DB:F2:5E:00:00', 'fixed-address': '10.12.24.81'}}, {'host host_118': {'hardware': 'ethernet DC:A6:32:B7:00:00', 'fixed-address': '10.12.67.22'}}]

If i uncomment printing named_file then i see whole file. So it means that the problem lies in parser.
