Input validation of CLI arguments

[johannesmoos]

Input validation of CLI arguments would be a valuable feature to immediately notice that a given CLI command is not valid (instead of waiting for the parser to do its thing and then wondering why there are no results :)

Currently all of the following get accepted:

pbgpp.py --pcap test.pcap --filter-message-type=TEST
pbgpp.py --pcap test.pcap --filter-message-subtype=TEST
pbgpp.py --pcap test.pcap --filter-next-hop=TEST
pbgpp.py --pcap test.pcap --filter-source-ip=TEST

I didn't test all of the arguments, but I guess it's not implemented at all currently.

Hey JMo! You are guessing right. At the moment there is no input validation regarding the command line arguments, except for those that are restricted to a list of well defined values (e.g. the message types).

Hi Tobias,

but then

pbgpp.py --pcap test.pcap --filter-message-type=TEST
pbgpp.py --pcap test.pcap --filter-message-subtype=TEST

should throw an error?
