@muarachmann Thanks for knocking this out.

I agree that summary and start_date_time should be mandatory. I think end_date_time should be optional. Let's use camelCase for these arguments, startDateTime and endDateTime.

Date time formats get really strange across languages and countries. What do you of having Y-m-d H:i as the default, but adding one more argument dateTimeFormat so they can provide any format they want to use as long as DateTime can understand it.

@SimplyCorey I see I did not cover extra parameters like categories, alarms, reminders, etc. To this effect, I think the structure should be slightly modified to something like this ...

QrCode::Calendar([
  'summary' => 'Summary of the Event', // Mandatory
  'location' => 'Event's location', 
  'url' => 'Event Url',
  'description' => 'event's full description',
  'categories' => ['Business', 'Anniversary'],
  'timezone' => 'Africa/Douala',
  'startDateTime' => 'Event start data and time', // DateTime format "Y-m-d H:i"  Mandatory
  'endDateTime' => 'Event end date and time', // DateTime format "Y-m-d H:i" Optional
  'alarm' => [
      'trigger' => [
              'weeks' => 1,
              'days' => 5,
              'hours' => 4,
              'mins' => 2,
              'seconds' => 0,
              'before' => true,  // by default
       ],
      'repeat' => 2,
      'description' => 'Foo's event will be made up of excellent gorceries',
      'summary' => 'You need to attend event Foo',
      ],
]);

@SimplyCorey Let me know your thought. Also I don't know why the CI keeps failing? it leads to an unauthorized link

I like that proposed method call.

The CI is failing because of a few issues with the code formatting. You should be able to use styleci.org and open a PR request to fix the styling issues using the laravel preset.

Worse case I can run the fixer after the PR is wrapped up to get the styling issues fixed.

@SimplyCorey Fixed the issues and added some more test. The Repeat Rule is so cumbersome and lots of parameters which I wont have time for now maybe later. Having to validate each stuff. How about letting this be a string for now and can point them to a global generator maybe in the docs. I found this tool quite handy for this https://www.textmagic.com/free-tools/rrule-generator

Aside that, everything else works from summary to alarm. Let me know your thoughts on this.

I'm okay with that. Thanks for working on this. Someone else can carry the torch in the future if that feature is wanted at a later time 👍

Year is not work correctly it repeat last two digit i.e 2021,1993 select this and output is 2121,9393 ...

My code is here below

QrCode::style('round')->size(300)->Calendar([
'summary' => 'Summary of the Event', // Mandatory
'location' => 'https://github.com//pull/202',
'url' => 'https://github.com//pull/202',
'startDateTime' => '2021-02-03 12:12', // DateTime format "Y-m-d H:i" Mandatory
'endDateTime' => '2021-02-03 12:12' // DateTime format "Y-m-d H:i" Optional
]);
