grec_minimal

A minimal parser/generator of Google Calendar recurrence rule for dart.

Synopsis

Parse recurrence rule text(s)

import 'package:grec_minimal/grec_minimal.dart';

void main() {
  final List<String> recurrenceRuleTexts = [
    'RRULE:FREQ=DAILY',
    // put recurrence rule texts
  ];

  List<RecurrenceRule> rules;
  try {
    rules = GrecMinimal.fromTexts(recurrenceRuleTexts);
  } catch (ex) {
    // There is possibility to occur InvalidSyntaxException and/or ConditionalException
    // do something
    rethrow;
  }

  rules.forEach((rule) {
    // do something
    print(rule.asRuleText());
  });
}

Dump recurrence rule text(s) from rule object(s)

import 'package:grec_minimal/grec_minimal.dart';

void main() {
  final List<String> ruleTexts = GrecMinimal.toTexts([
    new RecurrenceRule(Frequency.DAILY, 123, null, 2, null),
    // put recurrence rule object as you like
  ]);

  ruleTexts.forEach((ruleText) {
    // do something
    print(ruleText);
  });
}

Description

grec_minimal is a simple parser/generator of recurrence rule for Google Calendar.

This library provides two funnctions:

• A parsing function of recurrence rule text(s) that is generated by Google Calendar. It outputs recurrence rule object(s) according to give text(s).
• A generating function of recurrence rule text(s) from give rule object(s).

i.e. This library is an implementation of a subset of RFC 5545.

Disclaimer

This is not a full implementation of RFC 5545. This library is focused on using Google Calendar. It means some features are not supported (e.g. SECONDLY, MINUTELY).

So if you need full implementation of RFC 5545, please consider other libraries.
