i ran into this issue and wrote the following workaround using Luxon. since the library doesn't have a native removal API for exdates, you basically just have to reconstruct the entire RRuleSet
from scratch and just exclude the exdate in the new set:
export function removeExceptionDateFromRecurrenceRules(
recurrenceRules: string[],
dateTime: DateTime
) {
const oldRuleSet = getRuleSetFromRecurrenceRules(recurrenceRules);
const oldExdates = oldRuleSet.exdates();
if (oldExdates.length === 0) {
return recurrenceRules;
}
const newExdates = oldExdates.filter(d => {
// for our use case, we only need to match on the hour - you can get more granular if need be
return !dateTime.hasSame(DateTime.fromJSDate(d), "hour");
});
if (newExdates.length === oldExdates.length) {
throw Error(
"Tried to remove an exdate that does not exist on the specified recurrence rules"
);
}
const rules = oldRuleSet.rrules();
const newRuleSet = new RRuleSet();
rules.forEach(r => newRuleSet.rrule(r));
newExdates.forEach(d => newRuleSet.exdate(d));
return newRuleSet.valueOf();
}
Hi, first of all thanks for the nice library!
Is there a way to remove an
exdate
from anrruleSet
? I see it is possible to add one usingrruleSet.exdate()
, but I how do you get it out again?I tried filtering the exdate array and writing to
_exdate
directly, but it is read only.So how can I achieve this?
