I am building a small app that reuires some clever text pattern matching... In my controller, I''ll have a string that I will want to parse out to a datetime and a message, a la Google Calendar Quick Add. Examples: 10/30/2006 7pm message 10-30-96 7:00 pm message 10/30/2006 19:00pm message ... You see what I''m getting at. For a v1.0 release, I CAN publish some standards for users to adhere to regarding how the string should look, but I''m wondering how some more experienced programmers might attack this problem, from a high level view. What do you initially look for, what do you delimit on, how do you break the string up, etc. Would love some feedback, many thanks in advance! -stirman -- Posted via http://www.ruby-forum.com/.
Have a look at my validates_date_time plugin http://svn.viney.net.nz/things/rails/plugins/validates_date_time -Jonathan.

Jeepers, that''s pretty nice. Have you looked at DateboxEngine? http://rails-engines.org/wiki/pages/DateboxEngine It only handles dates, not times, and does it in Javascript.. but you might want to investigate some of the patterns it recognizes, like "next tuesday", "last monday" and month and date with an implicit year.

I''ve found that most users don''t want to type ''today'', and as I usually give them a date picker widget they''re pretty happy to just use that. I wouldn''t be adverse to adding support to parse more english-like dates such as ''today'', ''last tuesday'' etc..., feel free to write a patch if you want. Parsing with an implicit year is a good idea, I may add that at some stage. Again, patches welcome :). Cheers, Jonathan.

Wow, great plugin... Today I''ll be sorting through the code to see how I can apply it to my app. As I learn what you did, I''ll see about writing a patch to include some of the above-mentioned functionality. Many thanks, great work. -stirman www.stirman.net -- Posted via http://www.ruby-forum.com/.
