Hi Jan,
You can print via variables strings containing again references to other
variables - there is only one level of variable evaluation.
You should do it:
$var(msg) = $rm + "received on " + $var(hostname);
xlog("L_INFO", "$var(msg)");

Hello all,
I was going to centralized logging functions to a route block that
would be called from various place in script, using $param(n) to
access the log message. I got stuck on what I guess is variable
evaluation. Simplified this is the problem:
The normal (working) way:
xlog("L_INFO", "$rm received on $var(hostname)");
Output: INVITE received on proxy-stage-01
What I was trying:
$var(msg) = "$rm received on $var(hostname)";
xlog("L_INFO", "$var(msg)");
Output: $rm received on $var(hostname)
In the latter case the variables are not evaluated the way I was
expecting.
Is there a better way to achieve the output of the first example by
using a variable containing the message to xlog?
I am testing this on OpenSIPS 2.1.
Best regards,
Jan Blom
