I need to read and write octet streams to send over various networks to communicate with smart electric meters. There is an ANSI standard, ANSI C12.19, that describes the binary data format. While the data format is not overly complex the standard is very large (500+ pages) in that it describes many distinct types. The standard is fully described by an EBNF grammar. I am considering utilizing ANTLR to read the EBNF grammar or a modified version of it and create C# classes that can read and write the octet stream.

Is this a good use of ANTLR?

If so, what do I need to do to be able to utilize ANTLR 3.1? From searching the newsgroup archives it seems like I need to implement a new stream that can read bytes instead of characters. Is that all or would I have to implement a Lexer derivative as well?

If ANTLR can help me read/parse the stream can it also help me write the stream?

Thanks.

  1. This subject comes up from time to time on the ANTLR mailing list. The answer is usually no, because binary file formats are very regular and it’s just not worth the overhead.
