[OpenSIPS-Devel] [ opensips-Patches-3513177 ] Substitutions in configuration file

[Rudy]

Bogdan,

 Hey buddy! Conditionals are important too and m4 is a great tool,
don't get me wrong. It ends up being case of many ways to skin the cat
as they say. I think whats happening is just a result of OpenSIPs
continued growth. There is a demand not simply for OpenSIPs as a
component, but more as a platform for building solutions. This is
something we should all keep in mind when continuing to push in
different directions when extending OpenSIPs.

 Perhaps there is a happy medium for everyone here... maybe Nick can
write a patch for opensipsctl where it would run m4 against
<config>.m4 if it exists and compile it into <config> before starting
opensips. Nick, keep in mind, you should handle not just opensips.cfg
but any file passed as a -f argument in STARTOPTIONS env variable.
What do you think about this Bogdan? I would be in support of such a
change and it should be seamless to everyone else.

Thanks in advance,
--Rudy
