Search the world for a room name:

This extension to the do_vnum will search through your world for any
rooms that match the search word. It is essentially a hack of the 
other to vnum search options, but comes in pretty handy for when you
know that a room is somewhere, but can't remember where (in a very 
large world this can be quite a problem :P) (it will max out at 100 found
results to avoid spamming the viewer into oblivion if they search for 
"vnum room a") - Dana

(Note: This is a fix to the original that I put out last week. 
Thanks to Tim Yohn who pointed out my omission - for anyone who got
the original, the fix is to add: page_string(ch->desc, buf, TRUE); 
before the return(found) in vnum_room().)

in act.wizard.c
******************
ACMD(do_vnum)
{
  half_chop(argument, buf, buf2);

! if (!*buf || !*buf2 || (!is_abbrev(buf, "mob") && !is_abbrev(buf, "room")
!    && !is_abbrev(buf, "obj"))) {
    send_to_char("Usage: vnum { obj | mob } <name>\r\n", ch);
    return;
  }
  if (is_abbrev(buf, "mob"))
    if (!vnum_mobile(buf2, ch))
      send_to_char("No mobiles by that name.\r\n", ch);

  if (is_abbrev(buf, "obj"))
    if (!vnum_object(buf2, ch))
      send_to_char("No objects by that name.\r\n", ch);

+ if (is_abbrev(buf, "room"))
+   if (!vnum_room(buf2, ch))
+     send_to_char("    No room name containing that word.\r\n", ch);
}

in db.h
************
search for:
  int vnum_object(char *searchname, struct char_data *ch);
then add:
+ int vnum_room(char *searchname, struct char_data * ch);

in db.c somewhere add:
*************************
+int vnum_room(char *searchname, struct char_data * ch)
+{
+  int nr, found = 0;
+ char tempbuf[MAX_STRING_LENGTH];
+
+ sprintf(buf, "Results:\r\n");
+  for (nr = 0; nr <= top_of_world && found <=100 ; nr++) {
   // note: if you don't use color codes, you can take comment out the following
   // two lines, and do the isname as if(isname(searchname, world[nr].name)) - 
   // you can also remove the tempbuf variable above - not used for anything else.
   // note: buf2 is the same as searchname so don't use buf2 (you'll end up spitting
   // out all your rooms as a result). - don't add this comment to your code...
+   sprintf(tempbuf, "%s", world[nr].name);
+   remove_colorcodes(tempbuf); 
+    if (isname(searchname, tempbuf)) {
+      sprintf(buf + strlen(buf), "%3d. [%5d] %s\r\n", ++found,
+       world[nr].number,
+       world[nr].name);
+      if (found == 100)
+         sprintf(buf + strlen(buf), "**Too many results, please use a less common search word.**\r\n");
+    }
+  }
+  page_string(ch->desc, buf, TRUE);
+  return (found);
+}


If you don't have something like this - and you use color codes, 
add this to utils.c (with a declaration in utils.h so that it can
be used anywhere you might need it.
If you already have a function like this - or for some reason don't
want it to match up if there is color on the target string, either 
use your own function, or take out the call to this entirely ;)
