[sr-dev] New feature: #defexp -preprocessor define with expression

Hello, following the recent new feature of #!ifexp based on snexpr (https://www.kamailio.org/w/2022/09/ifexp-conditional-preprocessor-blocks/), another preprocessor directive was added which allows defining IDs with a value computed from the evaluation of an expression, respectively: #!defexp ID EXP The EXP can be any expression supported by snexpr, including the previously defined IDs. For example: #!define IPADDR 1.2.3.4 #!define PORT 5060 #!defexp SIPURI "sip:" + IPADDR + ":" + PORT The result is that SIPURI is defined to sip:1.2.3.4:5060. Another variant is available as #!defexps, which encloses the result of the expression in double quotes, making it suitable to be used further as string value: #!defexps SIPURI "sip:" + IPADDR + ":" + PORT The result is that SIPURI is defined to “sip:1.2.3.4:5060”.
