Please give it a try and, if you find any serious bugs you think ought to be fixed before we release it for real, send an email to

Among other things, 0.1.2 contains a preliminary version of the parser-localization API we discussed in my previous post. I took the advice of my (overwhelmingly helpful!) commenters and, instead of trying to factor out some kind of declarative grammar description, I left a space for a quite open-ended function that takes the input, the list of known verbs, and the list of known nouns, and returns a list of partially-parsed sentences. I think it should be general enough to allow for the full range of weirdness that is present in natural languages, while factoring out the all the common-across-languages behavior that the parser core should be handling for you.

The API is described in detail in the parser localization API tutorial I wrote. If you’re at all interested, please give it a read and let me know how you think it could be improved or clarified. (If you’re very interested, you might even try using it to write a parser plugin; if you want to try, I’ll be happy to answer any questions you have.)

P.S. Here’s the complete release notes for 0.1.2.
