hi !
i begin to play with js
i try to search in message base, but search one to one is poor performance
do you have another code that search in the base with more speed?
maybe some method more optimized?
a global menssage base index?
a gift from google? :)

for (grp in msg_area.grp_list) {
for (sub in msg_area.grp_list[grp].sub_list) {
msg = new MsgBase(msg_area.grp_list[grp].sub_list[sub].code);
if (msg.open()) {
for (i=0;i< msg.total_msgs;i++) {
mensaje = msg.get_msg_header(true,i);
if (mensaje != null) {
if (mensaje.subject.indexOf("hola") >= 0) {
writeln(mensaje.from);
writeln("<br />");
writeln(mensaje.subject);
writeln("<br />");
}
}
else
writeln ("error getting message");
}
msg.close();
}
else {
writeln ("Error al abrir la base de mensajes: " + msg_base.grp_list[grp].
}
}
}

Your script seems to just search the message subjects. This is slow?

my idea is search in to body of messages too(in future), to put it into a
web page, but i think to this will be more slow
i can export the msgbase in timed events to mysql engine or make a cgi in
c++ usign the msgbase api, but i dont know. i searching for ideas =?

I don't think any of that will be necessary.

Here's a variation on your script:

// search.js
// usage: jsexec search.js <msgbase_code> <search_string>

var msgbase_code = argv[0];
var search_string = argv[1];
var msgbase = new MsgBase(msgbase_code);
if(!msgbase.open()) {
alert("Error " + msgbase.error + " opening msgbase: " + msgbase_code);
exit();
}

var total_msgs = msgbase.total_msgs;
for(var i=0; i<total_msgs; i++) {
var hdr = msgbase.get_msg_header(true,i);
if(hdr.subject.indexOf(search_string)>=0)
print(hdr.subject);
}
print("Searched " + total_msgs + " messages.");
msgbase.close();

Run with jsexec on a a message base with 5000+ messages:

Searched 5007 messages.
s:\sbbs\exec\search.js executed in 14.34 seconds

That's about 350 message headers a second. Is that considered slow?
