[Ferm] How to do things without global variables

[Marc Haber]

Hi,

if ferm would have global variables, I'd want to write this:

(file globalvars)
@def $client_networks="";


(file int104)
# these are the rules for internal network 104
# this is a client network
@def $client_networks=($client_networks 10.1.104.0/24);

<other rules applying to this network snipped)


(file int108)
# these are the rules for internal network 108
# this is a client network
@def $client_networks=($client_networks 10.1.108.0/24);

<other rules applying to this network snipped)


(file client-networks)
# these are the rules for all client networks

saddr $client_networks subchain {
  (long list of client rules snipped)
}


Sadly, this doesn't work, as the $client_networks variable seems to be
local to the files and thus the $client_networks interpolated inside
the client-networks file is empty.

Is there a way to write this elegantly without having to resort to
writing a temporary file and including it inside the client-networks
file?

Any hints would be appreciated.

Greetings
Marc
