Re: Natural-language datetime parsing and display (was: user friendly datetime features)
or just calculate the difference between the moment you are and the date before and display the result in a cases (if diff is one day or 2 days or ...) -- http://mail.python.org/mailman/listinfo/python-list

I think the OP was looking for presentation of dates in a friendly format, not parsing, but it so happens that I started such a parser with pyparsing about a month ago, and was about 1/2 finished with it when I saw your post. I dredged up the code from where it was, and have a semi-working version now. NLTK is not needed, as you can constrain and structure the vocabulary surprisingly well. Probably trickier is to establish your own conventions for the meanings of now, today, etc. (For instance, I interpret today as the current date, at time 00:00:00.) A day from now is the current time, with tomorrow's date. In a day could go either way - interpret like tomorrow or like a day from now. But once these are settled, a reasonable grammar can be composed. My first version is fairly brute force and hackish, but I've gotten some insights into the date arithmetic, and which words behave much like operators. Of course, this is all driven around English and English idioms - converting to another language would probably be starting from scratch. Here are the tests for this first version (these tests all pass): today tomorrow yesterday in a couple of days a couple of days from now a couple of days from today in a day 3 days ago 3 days from now a day ago now 10 minutes ago 10 minutes from now in 10 minutes in a minute in a couple of minutes 20 seconds ago in 30 seconds 20 seconds before noon 20 seconds before noon tomorrow noon midnight noon tomorrow You can see the results and the parser code at: http://pyparsing.wikispaces.com/UnderDevelopment. -- Paul -- http://mail.python.org/mailman/listinfo/python-list
Re: user friendly datetime features
Why not build your own module? You can use it where and when you need it. jim-on-linux http://www.inqvista.com On Tuesday 08 January 2008 20:19, Daniel Fetchinson wrote: Many times a more user friendly date format is convenient than the pure date and time.

For PARSING see http://code-bear.com/code/parsedatetime/ The OP was looking for presentation though. I know roundup has code for this if an independent library can't be found. Eddie -- http://mail.python.org/mailman/listinfo/python-list

Thanks for all the responses! Indeed I was looking for presentation and not parsing, I'll take a look at roundup. Cheers, Daniel -- http://mail.python.org/mailman/listinfo/python-list
user friendly datetime features
Many times a more user friendly date format is convenient than the pure date and time. For example for a date that is yesterday I would like to see yesterday instead of the date itself.

The closest I know of is the Chandler Desktop release notes URL:http://chandlerproject.org/Projects/ReleaseNotes mentioning parsing of natural language date and time.
