If you need other kind of features, you can propose pull requests. Or you can eventually have a start script that sets defines with -A cli parameter based on env variables. Cheers, Daniel On 06.12.21 21:56, Ben Kaufman wrote: Thank you :)   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?   #!defenv WITH_DEBUGGER   #!ifdef WITH_DEBUGGER loadmodule "debugger" . . . #!endif         *Ben Kaufman*   *From:* Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; <mailto:miconda@gmail.com> *Sent:* Monday, December 6, 2021 3:55 AM *To:* Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; <mailto:sr-users@lists.kamailio.org>; Ben Kaufman &lt;bkaufman(a)nexvortex.com&gt; <mailto:bkaufman@nexvortex.com> *Subject:* Re: [SR-Users] Unquoted values from #!defenv   Hello, #!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. 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: #!define IDLOOP $var(i) = 0; \                 while($var(i)<5) { \                     xlog("++++ $var(i)\n"); \                     $var(i) = $var(i) + 1; \                 } See the core cookbook for more details.
