elkhound

I've heard of one C++ front end that uses it -- Elkhound -- but the only context I've heard of Elkhound is in GLR parsing!

My mom stumbled upon showing her dog at dog shows (she has a Norwegian Elkhound whose linage has won Westminster).

The Elkhound paper [1] explains GLR parsing in detail and is quite enjoyable to read.

I'd be interested to know if Coverity is still using McPeeks elsa/elkhound glr parser generator from years ago.

I gave up trying to get Scott McPeak's Elkhound C++ parser to compile, last I had to attempt it.

Interesting that back when McPeak was working on Elsa/elkhound clang wasn’t available.

Clang probably does everything Elkhound does, but better and faster.) I have looked at least 30+ parsers for programming languages.

In the tool I implemented several parsing strategies, notably "parsing expression grammars (PEGs)" as well as a GLR parser (based on the Elkhound paper).

I'd recommend reading the "Elkhound" paper [1], which introduces a GLR parser that's really easy to implement and very powerful, they use it in the paper to parse a large subset of C++.

Now Protocol Buffers are just a convenient way to create typed trees, just like the Elkhound "AST" project I linked above, but in a way that can be accessed from ANY programming language (that has protobuf support), not just one.
