<p class="MsoNormal">A follow up question would be on the usability of the #!defenv (and probably #!defenvs) usability with #!ifdef. In the scenario below, if the environmental variable WITH_DEBUGGER is not defined, then Kamailio will fail to start, thus the
#!ifdef is somewhat limited. It makes sense for scenarios where someone might toggle the setting editing the config file, but it would be very convenient to toggle the environmental variable instead, particularly in containerized environments. Any thoughts
on how best to control this?<o:p></o:p></p>

<p>Hello,<o:p></o:p></p>
<p>#!substdef does not set the value inside quoted string, it replaces inside a string value, so it does not put quotes around replacement part. So it does it it is written in the docs. There is #!substdefs witch can create a define with quoted value.<o:p></o:p></p>
<p>Note that defines are standalone-token replacement, you can define an ID to a number, to a keyword (e.g., src_ip), to a quoted string or even a multi-line script snippet, like:<o:p></o:p></p>
<p>#!define IDLOOP $var(i) = 0; \<br>
while($var(i)<5) { \<br>
xlog("++++ $var(i)\n"); \<br>
$var(i) = $var(i) + 1; \<br>
}<o:p></o:p></p>
<p>See the core cookbook for more details.<o:p></o:p></p>
<p>Anyhow, as using env variable values as quoted string is useful and setting them with quotes might look odd, I added #!defenvs:<o:p></o:p></p>

<p class="MsoNormal">Looking for some clarification regarding quoting and !#defenv . I understand that the example below fails because the environmental variable HOME is not quoted, thus when used in the xlog() call it fails. How is it possible to evaluate
and/or use the value of the environmental variable if defined as a preprocessor variable? Looking at the documentation the reason for this directive is “<span style="font-size:10.5pt;font-family:"Arial",sans-serif;color:#333333;background:white">It is a simplified
alternative of using <strong><span style="font-family:"Arial",sans-serif">#!substdef</span></strong> with <strong><span style="font-family:"Arial",sans-serif">$env(NAME)</span></strong> in the replacement part.</span>” But #!substdef would allow setting the
value inside of a quoted string, so does it really meet that requirement?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I’m aware that I could use $env(HOME) rather than a preprocessor directive of HOME. I’m just trying to understand the usage of the #!defenv feature.<o:p></o:p></p>
