Once that's done, any parser that uses it just needs to be made "incomplete aware". In some cases (ISO8601) being 'incomplete' will depend on the format it's parsing. Eg "2011" is a valid 8601 format. DT:F:ISO8601 would call strptime with { pattern => '%Y', incomplete => 1 }.
This wouldn't be a difficult modification to strptime, and would provide an easy route to ::incomplete for other parsers that already use strptime for parsing.

I just started using DateTime::Incomplete for a project and discovered that would be handy to have a string parser, so I came back and re-read this thread :) Regarding the message quoted below, my assessment is that all that is needed to be written (from scratch) is a DateTime::Format::Incomplete::Builder module -- then the various DateTime::Format::YourType modules can be mostly recycled into passing their parsers into this new modules. Alternatively, it might be possible to change the DateTime::Format::* family into constructing other object types (than vanilla DateTime), but that sounds like a refactoring pass to follow the initial version as I described above.

When parsing bibliographies, it's important to be able to distinguish between, say 2008 2008-01 2008-01-01 Every module I've found sets the day or month to "1" if it's not in the input which makes it impossible to tell if there really is a day/month in the input without parsing the input (which makes using a DateTime::Format module pointless ...). Is there a way to do this? I know about DateTime::Incomplete but that doesn't parse dates, you have to have already split the date up to pass to it ... It seems that all of the DateTime::Format::* modules parse into DateTime objects which always default day/month to "1". PK -- Dr Philip Kime
