#remove_minutes(typical, wd, from, to) ⇒ Object

What the window covers on that weekday is taken out of every interval reaching it: an interval inside the window disappears, one straddling it is split in two, and one only touching its edge is left alone. An open end belongs to the half that still runs to the end of the day.

#remove_time_range(typical, weekdays, times) ⇒ Object

The times a rule closes ("Mo-Fr 12:00-13:00 off") are cut out of what earlier rules left open on those weekdays, which is what leaves a lunch break rather than a closed day.

#split_day_offset(weekday) ⇒ Object

A selector can name a date by counting days from the one it selects: "easter +1 day" is Easter Monday, "PH -2 days" the day before the eve of a public holiday. Returns the selector without its suffix and the offset in days, zero when there is none.

  [match.pre_match, match[1].to_i]
end

#split_into_rules(tokens) ⇒ Object

A time selector closes a rule sequence, so any selector standing right after one opens a new rule. That is what the additional rule separator means ("Jan We 11:00-12:00,Mo off" is two rules, and the second one carries no month), and it also reads the rules the data writes with no separator at all ("Feb: Mo 09:00-19:00 Mar-Jun Th 09:00-19:00").

A rule modifier and a comment belong to the rule they follow, and a second time selector only widens the current one. Returns [tokens, additional] pairs. Every rule but the first of a ";" block is an additional rule: it adds to what comes before it rather than replacing it, which is what "Sa,Su 18:00-24:00; Jan Fr 10:00-20:00, Sa 00:00-03:00" means, the Saturday of the first rule surviving.

#split_weekday_selector(weekday_selector) ⇒ Object

A weekday sequence is comma separated, but an index list is comma separated too ("Sa,Su"), so only the commas outside the brackets separate weekdays.
