I have refactored the parsing functionality used by both text2pcap and the GUI into the ui/ folder and checked it in. The ISO-8601 date support does work in the GUI, through the undocumented hack of putting "ISO" for the time format string (the GUI will accept it), same as what text2pcap accepts. Everything supported by one or the other still works, but there's a few features that only one supports (see https://gitlab.com/wireshark/wireshark/-/issues/16724 for an issue tracking): CLI missing: 1) Regex support 2) Export PDU 3) No offset, everything into one big packet (should be easy) GUI missing: 1) IPv6 dummy headers 2) Custom IPv4 and IPv6 addresses 3) Special try extra hard to deal with hex+ASCII dumps where the ASCII coincidentally looks like a byte 4) Writing to pcap instead of pcapng The documentation needs to be updated, and then after that there's a few possible enhancements that would be nice to have. (Use command line options similar to other CLI, support other file formats, etc.) John Thacker
