Some parts of naxalnet can be configured by configuration files and

|

is taken. Then, key-value pairs from the configuration files are read, if
|
||||
they exist, in the following order:
|
||||
|
||||
- First it reads /usr/share/naxalnet/naxalnet.conf and then from
|
||||
/usr/share/naxalnet/naxalnet.conf.d/*.conf where *.conf means any file
|

with the name ending with ".conf". The files in this directory are

intended to be used by distribution and package maintainers.

where *.conf means any file with the name ending with
|

".conf". The files in this directory are intended
|

to be used by distribution and package maintainers.
|

- Next, it does the same with /usr/local/share/naxalnet
|

- Then, it looks for the files naxalnet.conf and
|
||||
naxalnet.conf.d/*.conf from the directory
|

/etc/naxalnet, like it did up above. This directory is where
|

the user creates and stores the config file.

storing the values in the files parsed until now
|

as fallback. Finally you get an argpase.Namespace object
|

from parse_args().
|
||||
Because of the way this is implemented, all key-value
|
||||
pairs in the configuration should have an argument
|
||||
too, or they won't be parsed.
|
||||
|
||||
All the key-value pairs are replaced successively if they exist
|
||||
by each new configuration file parsed, similar
|
||||
to how systemd parses configuration and service files.
|
||||
If any of the files checked does not exist, then they are
|

ignored and the next combination is checked. If none of

the config files exist and no arguments are given, the

fallback data from default.py is used.
