proto_tree_add_item new line

Question

The proto_tree_add_item displays each filter in a newline in the CLI. Is there a way to display the filters in the same line.

Ex.

    proto_tree_add_uint(tree, hf_s1, tvb, 0, 1, s1);    
    proto_tree_add_uint(tree, hf_s2, tvb, 0, 1, s2);

I want them to be s1 and s2 to be displayed in the same line as

    s1 : 12,  s2 : 13

rather than

   s1 : 12
   s2 : 13

Answer 1

Not for a filter (I think you actually mean an hf item). The text for each entry can be built from multiple packets in the frame, or synthesise out of thin air if you wish though.

Answer 2

The only way to display multiple fields on the same line is to use the -T fields option to TShark, for example

tshark -r inputfile -T fields -e ip.src -e ip.dst -e ip.ttl

which will show the IPv4 source address, destination address, and TTL on the same line. If any of those fields are missing, it will show a blank, so, for example, non-IPv4 packets will show a blank line.
