C output?

[dtaht]

I am curious if this tool (or some other tool) could take a packet description like this of a more complex protocol and turn it into a streaming parser for a C based daemon, in addition to hardware?

(my intent was to write a packet parser for the babel routing protocol, I was looking over peg, ran across your paper, and here I am)

I rather like the descriptive language....

Hi @dtaht,

My notifications were misconfigured and I only just discovered your message.

Right now this tool doesn't have the ability to generate C code.

I suggest that you take a look at the work being done by the P4 Language Consortium (http://p4.org). The P4 language has much richer constructs for describing parse graphs, although the language goes beyond just packet parsing. They also provide a compiler that will turn a P4 program into executable switch software.

thx. P4 was not quite powerful enough to do codel and fq when i'd last looked. I'll go catch up on it.
