A small library for dealing with FidoNet-style addresses

Currently only handles 3D and 4D addresses cause that's what SMB stores
in msg headers (and all I need right now).

exec/load/fidoaddr.js

+// $Id$
+
+function parse(str)
+{
+	var addr = str.match(/^(\d+):(\d+)\/(\d+)$/);				// 3D
+	if(!addr)
+		addr = str.match(/^(\d+):(\d+)\/(\d+)\.(\d+)$/);		// 4D
+	if(!addr)
+		return false;
+	for(var i=1; i < addr.length; i++)
+		if(parseInt(addr[i], 10) > 0xffff)
+			return false;
+	return { zone: addr[1], net: addr[2], node: addr[3], point: addr[4] };
+}
+
+function is_valid(str)
+{
+	if(!str || !str.length)
+		return false;
+
+	return parse(str) != false;
+}
+
+function to_inet(addr)
+{
+	if(typeof addr == "string")
+		addr = parse(addr);
+	if(!addr)
+		return false;
+	if(addr.point)
+		return format("p%u.f%u.n%u.z%u", addr.point, addr.node, addr.net, addr.zone);
+	return format("f%u.n%u.z%u", addr.node, addr.net, addr.zone);
+}
+
+function to_filename(addr)
+{
+	if(typeof addr == "string")
+		addr = parse(addr);
+	if(!addr)
+		return false;
+	return format("%04x%04x", addr.net, addr.node);
+}
+
+this;
