[sr-dev] runtime pv evaluation

Hello, currently I am looking for an option to evaluate a string with pseudo-variables at script runtime. For example when reading the following string (in script) from database "from is $fu and to-uri-user is $(tu{uri.user}) and cl is $cl" into a pseudo-variable $var(tmp) I want kamailio to parse the _content_ of $var(tmp): replace the "inside"-pvs with their values and perform transformations. Is there a function exported to script, that could do that? (Background: I would like to make the lcr-module a bit more flexible: read "template"-string for fromuri, touri, ruri from database instead of ruri-strip, ruri-prefix etc.) Kind Regards Jasmin
