natty

So, Siri for the terminal? Cool idea but your implementation won't scale (more complex commands and/or beyond English). You need a grammer file and some NLP library. Look at how this is implemented: http://natty.joestelmach.com/ Their core is implemented in this grammer file: https://github.com/joestelmach/natty/blob/master/src/main/an... Take a look at this too since you wrote it in python: http://www.nltk.org/

Thanks for the feedback. The chronic project was actually the original motivation behind natty. I think the chronic project is great, but I believe the grammar-based, AST approach is the way to go for long-term maintainability. Implementing relative times has been on my list of things to do (in addition to recurrence.) I created a feature request here: http://github.com/joestelmach/natty/issues#issue/4, so feel free to list any time formats you'd like to see implemented. I agree that a generic list of test cases would be nice. Any thoughts on how such a list should be published?

Thanks for the feedback. I'll admit to the amateur mistake of not handling leading white space (that's now fixed on the master branch.) It looks like the only example from your list that couldn't be parsed is "The day before Sunday week". Forgive my ignorance, but I've never seen 'week' used in that context here in the US. If you'd be willing to describe the proper use, I'll look at implementing it. As for the UK format, please see the issue I created here: http://github.com/joestelmach/natty/issues#issue/3, and lend some advice if you'd like. The test set is available here: http://github.com/joestelmach/natty/blob/master/src/test/gun...
