[OpenSIPS-Devel] New Transformations Available

[Vlad Paiu]

Hello,

I have committed a new version that allows bitwise operations for string 
variables.
It is now possible to do something like this, from the OpenSIPS script :

$var(mask) = "255.255.0.0";
$var(ip) = "192.168.2.134";
$var(net) = $(var(mask){ip.pton}) & $(var(ip){ip.pton});

if ($(var(net){ip.ntop}) == "192.168.0.0")
     xlog("IP is in 192.168.0.0/16 network\n");

As for back-porting to 1.6, it will be done, but only after more 
testing, when we will be sure that the version is stable.

Regards,
