ISCpy

ISCpy a robust ISC config file parser. It has virtually unlimited possibilities for depth and quantity of ISC config files. ISC config files include BIND and DHCP config files among a few others.

The example below shows how to parse a canonical Bind configuration as generated by running named-checkonf -p.



In [1]:

    
import iscpy



In [6]:

    
with open('named.conf') as fp:
    s = fp.read()



In [9]:

    
config = iscpy.ParseISCString(s)



In [10]:

    
type(config)









    Out[10]:





dict

The config dictionary is keyed by the different sections of the Bind configuration.



In [11]:

    
config.keys()[0]









    Out[11]:





'zone "86.168.192.in-addr.arpa"'



In [13]:

    
set([key.split()[0] for key in config.keys()])     # 'view' missing in this example









    Out[13]:





{'acl', 'controls', 'key', 'logging', 'options', 'server', 'zone'}



In [18]:

    
acls = {key: value for key,value in config.items() if key.startswith('acl')}
zones = {key: value for key,value in config.items() if key.startswith('zone')}
# etc.
acls.keys()









    Out[18]:





['acl myfirstacl']

The sections are dictionaries again. Note that lists are converted into dictionaries with values set to True.



In [15]:

    
config['zone "86.168.192.in-addr.arpa"']









    Out[15]:





{'file': '"rev/86.168.192.in-addr.arpa"', 'type': 'master'}



In [16]:

    
config['zone "16.172.in-addr.arpa"']









    Out[16]:





{'file': '"slave/168.192.in-addr.arpa"',
 'masters': {'192.168.17.12': True, '172.16.1.10': True},
 'type': 'slave'}
