Different types of habits

[Ben-Baert]

Currently, the only type of habit is a quantified one that has a certain target that is met if it is either reached or surpassed. There are, however, other possibilities:

• a target where you want to be as low as possible. For instance, if my goal is to wake up at 6 a.m., waking up at 5.30 a.m. is okay, but waking up at 6.30 a.m. is not.
• some goals may just require a boolean value, that is, either you did them or you didn't. (Silly) examples include: take the bike rather than the car to work, take off shoes inside,... You can't really quantify these; either you took the bike today or you didn't; either you took off your shoes or you didn't.

This is definitely a non-exhaustive list, and only meant to start a discussion.

Good discussion :)

Here's one more:

• # of meetings/week. It is very difficult to quantify this on a daily
  basis for tracking.

Regarding your last point, I think we can generalise it to having more custom frequencies.
Examples:

• every day (probably most common and a sensible default)
• every week at the end of the week (nr of meetings)
• every saturday (play tennis on Saturday)
• every two days (go for a run)
• every two weeks (go for a long hike)
• ...

You get the idea

For the habits, we could have the following model:

• name (str, required)
• start_date (date, required, default: today)
• finish_date (date, optional: leave empty for lasting habit, default: None)
• constant_target (bool, optional, default: True)
• start_target (float, leave empty for constant target, default: None)
  This can potentially be set even if there is a constant target to indicate the desired direction, for example with the waking up example, the start_target could be set to 7 a.m. and the finish_target to 6.am. Even if the target is constant, the system can derive that you want to be as low as possible by seeing that the finish_target is lower than the start_target.
• finish_target (int: leave empty for boolean target, default: None)
• units (str, leave empty for boolean target, default: None)
• update target (str: required, default: 'every')
  Frequency string, see log frequency. This is how often the target is updated, either automatically if update_target_automatically is set to True, or is asked to update if update_target_automatically is set to False.
• update_target_automatically (bool, optional, default:True)
• log frequency (tuple, required, default: ('every', 'day', None))
  • tuple:
    • first element: frequency (e.g. 'every', 'every.two')
    • second element: unit (e.g. 'hour', 'day', 'week', 'month')
    • third element (not sure): at (specific time or range) (e.g. '7 p.m.' '7p.m. - 11 p.m.); empty means anytime, range means expect log within that time range

Not entirely related, but also useful would be a config file with date and time format (12h vs. 24h, MM/DD vs DD/MM, etc) and begin and end time of a day (e.g. if you work until after midnight, habits are added to the previous day by default).
