IDE for lua

[chuck <chuck@...>]

I have posted items questions on various forums and hope to try
here.
1- what free IDE do you pros. suggest.
2- how do you suggest processing the following portion from by webserver
with lua daily as a process.
============================

[DHCP IP: (192.168.20.109)] to MAC address 00:16:B6:94:60:26, Tuesday, Dec 13,2011 19:06:03 and I would like to extract the MAC address
and
[DoS attack: Smurf] attack packets in last 20 sec from ip [178.151.111.21], Tuesday, Dec 13,2011 07:14:20 and I would like to extract the IP address
and [LAN access from remote] from 82.228.252.76:14961 to 192.168.20.109:42765 Monday, Dec 12,2011 09:57:50 and I would like to extract the first IP address
I get large files of these each day from my webserver and would to be able to extract these three items to which I can then post process and so on. Thanks if you can help. Chuck
