About a year ago I wrote a Wireshark protocol dissector in Lua.
You might find it helpful (BSD licensed):

When I was writing it I had a hard time finding good up-to-date documention on 
the Lua Wireshark API (I hope that has changed since then).

It even contains a simple lexer & parser since the protocol it dissects uses a 
text file to describe the different message formats (similar to Google's 
Protocol Buffers) that each UDP packet can contain.
