class SafeConfigParserWithIncludes(SafeConfigParser): |

""" |
|
Class adds functionality to SafeConfigParser to handle included |
|
other configuration files (or may be urls, whatever in the future) |
|
|
|
File should have section [includes] and only 2 options implemented |
|
are 'files_before' and 'files_after' where files are listed 1 per |
|
line. |
|
|
|
Example: |
|
|
|
[INCLUDES] |
|
files_before = 1.conf |
|
3.conf |
|
|
|
files_after = 1.conf |
|
|
|
It is a simple implementation, so just basic care is taken about |
|
recursion. Includes preserve right order, ie new files are |
|
inserted to the list of read configs before original, and their |
|
includes correspondingly so the list should follow the leaves of |
|
the tree. |
|
|
|
I wasn't sure what would be the right way to implement generic (aka c++ |
|
template) so we could base at any *configparser class... so I will |
|
leave it for the future |
