[sr-dev] runtime pv evaluation

[Jasmin Schnatterbeck]

Hi Henning,

thanks for your message.

Unfortunately the pv_printf function is not what I am looking for.

When the pv $var(tmp) _contains_ the string "from is $fu and to-uri-user 
is $(tu{uri.user}) and cl is $cl"

and I use pv_printf:

pv_printf("$var(tmp2)","$var(tmp)");

Then - as far as I understand pv_printf(?) - $var(tmp2) contains
"from is $fu and to-uri-user is $(tu{uri.user}) and cl is $cl"
and not:
"from is sip:user at example.net and to-uri-user is user2 and cl is 1324"

So I need something like an "eval"-function, that
1. evaluates the string in the argument (as pv_printf does it)
2. evalutes the resulting string again (in the same way)

Kind Regards
Jasmin
