Hi,
I am happy to announce the availability of PetitParser2, a wonderful redesign of the original PetitParser developed by Jan Kurš. https://github.com/kursjan/petitparser2
Highlights: - it introduces the compiler facility that speeds up parsers by a factor of ~2-5x - it introduces the possibility of parsing streams without having them in memory - it comes with a new structure internally that makes it more flexible - it introduces asPParser (not a typo) to be able to have the new version working in parallel with the classic asParser
The version is already present in the latest Moose 6.1 in parallel with PetitParser. Also, several of the parsers that are shipping with PetitParser were already copied to PetitParser2 as well.
You can find more details here: http://www.humane-assessment.com/blog/introducing-petitparser2/
Some more documentation will follow.
I think Jan did a wonderful job and the result is quite exciting. Please take a look and let us know what you think.
Cheers, Doru

Hi Doru,
i didn't had the time to look at it but we are really interested about this at synectique.
Thanks for your work and the cool explanations post!

Not yet, because I couldn't run a fresh Moose ;)

Because of Iceberg? If yes, I disabled it until we can safely run it on Windows.

Hi Guillaume,
Please feel free to contact me if you have any questions. I would be really please if syntectique finds it useful.
There is a potential for further optimizations and we can work on it.
Cheers Jan

I would like to integrate it in LRP, but I’m a bit swamped at the moment so I have not looked at it at all, sorry. Hopefully before the end of the year. :-/

The benchmarks are delivered with PP2, so far there are pre-prepared benchmarks for:
- simple arithmetic expression grammar - smalltalk grammar/smalltalk parser - java parser (if you download PetitJava)
You can run it on your own, e.g.:
PP2Benchmark exampleSmalltalk
Currently I am working on optimization of context sensitive grammars as well.
As I said before, there is a space for optimizations. If you can identify a bottleneck, there is a very high probability the PP2 can be extended to fix that.
Cheers, Jan
