Configuration Utility Module |
||||
|
||||
This module contains functions to load and verify very simple configuration |
||||
files. Python supports ".ini" files, which suck, so this module is used |
||||
instead. |
||||
|
||||
Example Configuration File: |
||||
|
||||
include /path/to/other.cf |
||||
|
||||
# these values are the same: |
||||
name_protected = "Michael Spang" |
||||
name_unprotected = Michael Spang |
||||
|
||||
# these values are not the same: |
||||
yes_no = " yes" |
||||
no_yes = yes |
||||
|
||||
# this value is an integer |
||||
arbitrary_number=2 |
||||
|
||||
# this value is not an integer |
||||
arbitrary_string="2" |
||||
|
||||
# this is a key with no value |
||||
csclub |
||||
|
||||
# this key contains whitespace |
||||
white space = sure, why not |
||||
|
||||
# these two lines are treated as one |
||||
long line = first line \\ |
||||
second line |
||||
|
||||
Resultant Dictionary: |
||||
|
||||
{ |
||||
'name_protected': 'Michael Spang', |
||||
'name_unprotected:' 'Michael Spang', |
||||
'yes_no': ' yes', |
||||
'no_yes': 'yes', |
||||
'arbirary_number': 2, |
||||
'arbitrary_string': '2', |
||||
'csclub': None, |
||||
'white space': 'sure, why not' |
||||
'long line': 'first line \\n second line' |
