Hi guys, I'm writing a program with a feature of accepting user input as command text and parsing it to correct function calls...example:
"5 minutes later"/"5 min later"/"5 minute later"/"after 5 minutes"... are being parsed as the same rule so the system will call a later function with minutes=5 as parameter. Of course there are many other possiblilities, "seconds"/"days", and even "every(each) hour"/"every Monday"/"every two days"...so on... The datetime computation can be done with the wonderful "dateutil" package, but I'm not sure with the command text parsing part. I could do a lot of regular expression, but it'll be great if there is already something similar available...or even a hint that can make it easier than hand-writing a lot of regular expression code... Another requirment is to display useful hints when user input the command text. Example: user input:"5" -> hints: "5 minutes later/5 hours later/5 days later/every 5 minutes" user input:"fi" -> hints: "next Friday"/"first thing tommorrow" user input:"ne" -> hints: "next day"/"next hour"/"next week"/"next month" Sounds too intelligent to do? Any advices on this? Thanks guys. Andy -- http://mail.python.org/mailman/listinfo/python-list
