Re: Lua Dissector Dev Tool

[Markus Leballeux <markus.leballeux () gmail com>]

Pascal,

That question makes a lot of sense actually. You are correct, Wireshark and
Wirebait don't use the same version of Lua and I can think of 2 kinds of
compatibility "challenges":

   1. *Compatibility between Wireshark and Wirebait:* Wireshark and
   Wirebait *never* interact with each other. Wirebait is only used when
   you run your dissector without Wireshark, so Wireshark never even loads
   Wirebait code.
   2. *Compatibility between a plugin developed with Wirebait and
   Wireshark:* your point was probably that someone could write a plugin
   using syntax only available in 5.3. This is definitely possible, which is
   why a 5.2 version is on the back burner. I have used 5.3 for convenience,
   and at this stage of the project I don't think this is going to be a big
   issue. If you are aware of the syntactic differences, you can write a 5.2
   compatible dissector and run it on Wirebait 5.3.

Sincerely,

Markus
