|
|
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]
|
|
before = 1.conf
|
|
3.conf
|
|
|
|
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
