Thank you very much. I'll give it a try later this week. -- Juha ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] pseudo variables in strings
I added pv_evalx() function in pv module which evaluates twice a string
containing variables. No time to test it, so any feedback is
appreciated. It will be also good to stress test it and check if there
is a memory leak for pkg, as the result for first evaluation needs to be
parsed again for other variables -- pv caching should prevent a leak,
but to be safe is good to test if plans are to use in production.
Cheers,
Daniel

I made a test rule:
match_exp subst_exp repl_exp
^\#11\#$ (empty)$fu
and dp_translate(id) on sip:#11#@test.tutpro.com produced
sip:$f...@test.tutpro.com.
Same with or without
modparam("dialplan", "match_dynamic", 1)
Also, I would prefer to have a function to evaluate strings rather than
have a dp_translate specific feature.

Dialplan can evaluate variables, is it a special case you need to return
variables and then evaluate after dp_translate() again?
It might work by returning a lua script string that you can evaluate
with app_lua().

Alex,
I cannot do that, because the string that contains pvs is result of
a dp_translate call.

No luck with that either. This test
$var(pv_string) = "foo$var(pv)bar";
$var(pv) = "car";
$var(res_string) = $_s($var(pv_string));
xlog("L_INFO", "res_string is '$var(res_string)'\n");
produces to syslog:
Apr 2 11:07:26 lohi /usr/bin/sip-proxy[24536]: INFO: res_string is
'foo$var(pv)bar'
when I need to get 'foocarbar'.

Re: [SR-Users] pseudo variables in strings
Juha,
Yes, either by separating the PV elements, e.g.
$var(x) = $fU + "abc";
... or with the newer $_s() PV created for this purpose:
$var(x) = $_s($fUabc);

Subject: [SR-Users] pseudo variables in strings
If I have a string that contains pseudo variables, e.g,,
$var(uri_pattern) = "sip:$f...@tutpro.com";
is it somehow possible to replace them with their values, something like:
$var(uri) = eval("$var(uri_pattern)");
