Augmented Backus-Naur Form Parser

[OrangeHopper]

Come on you lot, make my day!

I've been looking at language parsers and have come to the conclusion that the Augmented BNF syntax would be ideal. The main reason being the ability to specify lengths of tokens rather than just 0 or more, 1 or more and so on as with straight or Extended BNF.

The problem is I have failed to find a shareware parser for Augmented BNF. I have found things like JavaCC and ANTLR but not one that states it is for Augmented BNF.

So, the questions is, have I missed something? Why aren't there ABNF parsers out there?

Don't you mean "Extended" not "Augmented"?

Ah, the resident genius.

Nope, I'm interested in Augmented as in RFC2234 which gives the <a>*<b>element augmentation.

Extended only gives the *, + and ? extentions.

Are you wanting a parser or a parser generator?

Are you wanting a parser or a parser generator?

Parser generator I assume.

I want to write a ABNF specification for a particular protocol and produce a parser for instances of messages using that protocol.

Have you looked at APG?

[OrangeHopper]

That looks pretty good. Pity only in C++ but I can probably live with that.

Obviously a man with greater surfing skills than moi.

Any other offerings?

.Net version 5 will have one. Honest.

Apple will switch to Windoze soon, the Dvorak chappy said so.
