Unification of command line parameters for the sharks

[Joerg Mayer <jmayer () loplof de>]

Hello List,

this is a request for comments.

I wanted to add half a dozen -d (decode as) options to wireshark and found
that this feature does only exist for tshark and that -d is used by something
else (initial display filter).
My first idea was do rename -d on wireshark to something else and copy the tshark
-d to wireshark. Then I didn't like the idea of copying code from tshark to
wireshark. I'm not a big fan of code duplication and the inconsistencies between
the command line options between the sharks is annoying.

What about having a shared command line parsing code for all the sharks?

Options fall into two categories:
- global options that are available to all the tools and
- gui options are specific to a particular gui. Gui options might
  be changed to -g<gui-specific-option-name> (or any other inconvenient
  letter). They would have the -g stripped and passed to a gui specific
  parser.

This would have the side effect of making all core features available to
all sharks (like: is there a reason why I can either have the summary line
in tshark or the detailed decoding but not both and the decode as).

Comments on this?
Which other inconsistencies are there?

Ciao
      Jörg

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
