Datetime Interface

[melvintzw]

Context:

Our overlap_finder.find_all_common_intervals is able to take in a list of labeled Datetime Intervals (labelled with userid), and return a dictionary where the key is a common datetime interval (which we refer to as overlaps) , and the value is the set of userids that associate with that overlap. An example printout is shown in the code snippet below.

Mission:

We need to specify how datetime interval information should be passed to the bot as a string. Broadly, the question is how should you chat with the bot to pass it datetime interval information? Next, we need to write a parser to parse the bot's representation of a datetime interval into Interval objects that contain Datetime objects. We also need to attach user data to the Interval object for identifying who the interval is associated with.

Some approaches: explore libraries that parse natural language into datetimes, find or build a Telegram keyboard for datetime input, specify a fixed quick-and-easy string format.

Long-term goal:

Calendar Integration - integrate parser with calendar files (e.g. .ics files)
