I recommend you use the original package.\n\n\n*NB*: The rest of this Readme is the original readme from the original package.\n\n# grec_minimal [![Build Status](https://travis-ci.org/moznion/dart-grec-minimal.svg?branch=master)](https://travis-ci.org/moznion/dart-grec-minimal)\n\nA minimal parser/generator of Google Calendar recurrence rule for dart.\n\n## Synopsis\n\n### Parse recurrence rule text(s)\n\n\n```dart\nimport 'package:grec_minimal/grec_minimal.dart';\n\nvoid main() {\n  final List\u003cString\u003e recurrenceRuleTexts = [\n    'RRULE:FREQ=DAILY',\n    // put recurrence rule texts\n  ];\n\n  List\u003cRecurrenceRule\u003e rules;\n  try {\n    rules = GrecMinimal.fromTexts(recurrenceRuleTexts);\n  } catch (ex) {\n    // There is possibility to occur InvalidSyntaxException and/or ConditionalException\n    // do something\n    rethrow;\n  }\n\n  rules.forEach((rule) {\n    // do something\n    print(rule.asRuleText());\n  });\n}\n```\n\n### Dump recurrence rule text(s) from rule object(s)\n \n```dart\nimport 'package:grec_minimal/grec_minimal.dart';\n\nvoid main() {\n  final List\u003cString\u003e ruleTexts = GrecMinimal.toTexts([\n    new RecurrenceRule(Frequency.DAILY, 123, null, 2, null),\n    // put recurrence rule object as you like\n  ]);\n\n  ruleTexts.forEach((ruleText) {\n    // do something\n    print(ruleText);\n  });\n}\n```\n \nSee also: [example/](./example)\n\n## Description\n\ngrec_minimal is a simple parser/generator of recurrence rule for Google Calendar.\n\nThis library provides two funnctions:\n\n- A parsing function of recurrence rule text(s) that is generated by Google Calendar.\nIt outputs recurrence rule object(s) according to give text(s). \n- A generating function of recurrence rule text(s) from give rule object(s).\n\ni.e. This library is an implementation of a **subset** of [RFC 5545](https://tools.ietf.org/html/rfc5545).\n\n## Disclaimer\n\nThis is **not** a full implementation of [RFC 5545](https://tools.ietf.org/html/rfc5545).\nThis library is focused on using Google Calendar. It means some features are not supported (e.g. `SECONDLY`, `MINUTELY`).\n\nSo if you need full implementation of RFC 5545, please consider other libraries.\n\n## License\n\n```\nThe MIT License (MIT)\nCopyright © 2018 moznion, http://moznion.net/ \u003cmoznion@gmail.com\u003e\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the “Software”), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in\nall copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
