Re: [OpenSER-Users] 'while' statement in config file

Hello, although is more part of devel, the decision will affect users of future stable releases, so I posted on both lists. Maybe some of you noticed that in the ongoing process of improving the pseudo-variables system, the AVPs and HDRs can be accessed with dynamic index. That means next lines are correct in the config file. $var(i) = 1; xlog("$(avp(i:20)[$var(i)])"); if($(avp(i:20)[$var(i)]) == 3) { } In the past, the index was static, as a number. The question I want to address is whether makes sense to add 'while' statements to iterate through avps or hdrs. More or less, the cycles can be done via recursive routes. The block: $var(i) = 0; while($(avp(i:20)[$var(i)]) != null) { ..... $var(i) = $var(i) +1; } is equivalent with: $var(i) = 0; route(1); .... route[1] { if(($(avp(i:20)[$var(i)]) == null) return; ... $var(i) = $var(i) +1; route(1); } 'while' may look more attractive, but could open the pandora box, people asking for more and more, that will turn config language is something very complex (not saying that is simple now :-) ). The drawback with recursive routes is the fixed number of routes that can be defined with the standard openser: 40 (number can be increased if openser is recompiled), because for each cycle another route has to be used. Waiting for your opinions... Cheers, Daniel _______________________________________________ Users mailing list Users(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/users
