Hi Richard, Your project sounds interesting, but I get a 404 when I visit the link you listed below. I've never done anything with "GitLab" - do you have to make it "public"? It doesn't show up on your personal page either. Smith

Since it is now at the point where it generates code that builds and runs, I thought I would make it available for anyone who is interested in looking at it. My test example is based on the IEEE1905 specification. The dissector generator takes a protocol description that looks like a set of data structure definitions and generates a complete Wireshark dissector in C. The test example consists of about 252 lines of definition, and the generator currently generates around 1044 lines of C which builds and runs. Writing such a protocol description is much easier than the learning curve required to actually manually write the 1044-line dissector. Attached is a screen shot showing the result. It is annotated with some issues I think need rectifying, but I am going to take a break from this for a while. Anyone who is interested is welcome to try it out and send me suggestions or patches. Currently, it is not for the faint-of-heart. You need Antlr4 and a Java environment as well as a Wireshark development environment. In the future I expect to: 1. Remove the need for Antlr4 by shipping the generated Parser as jar files or something. 2. Tidy up and refactor the code so that different generator backends can be used, including a LUA back-end to make it much easier when developing dissectors. 3. Add in the handling of exceptions. 4. Maybe create other backends. (Once you have a protocol description it can be used for other things.
