Good day @rafarosa92

The code

require 'fugit'

c = Fugit::Cron.parse('0 0 * *  sun')

p c
p c.next_time.to_s

outputs

#<Fugit::Cron:0x0000044006aaa4c0 @original="0 0 * *  sun", @cron_s=nil, @seconds=[0], @minutes=[0], @hours=[0], @monthdays=nil, @months=nil, @weekdays=[[0]],
@zone=nil, @timezone=nil>
"2020-06-07 00:00:00 +0900"

The context is

$ uname -a
OpenBSD terebi 6.7 GENERIC.MP#1 amd64

$ ruby --version
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-openbsd6.6]

$ bundle list
Gems included by the bundle:
  * bundler (1.17.2)

So it works for me.

If you want me not to close this issue, you have to provide me a way to reproduce the problem.

Could you please indicate what OS you are using, what Ruby version you are using, and what fugit version you are using. Those things are requested by the issue template, but are missing from your issue report.

Thanks in advance.

I´ll test on a docker with your settings...

[jmettraux]

Just tested on the same system but with fugit 1.3.5 as you do, and I can't see your error. It works as well.

[jmettraux]

@rafarosa92 Is the error backtrace in your initial report complete? It seems to obfuscate where the NullMethodError is actually occurring.

[jmettraux]

Just test on the same system with fugit 1.3.5 and ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-openbsd6.7] (close enough to yours). Still successful. Tried both with my program and with irb as you do.

I'm not using Docker, I'm using a plain Ruby "project" with its .ruby-version and its Gemfile, it's at https://gist.github.com/jmettraux/f657b8b17a05de95ba55d5d7345b9e36

I have to go to bed now. Let's hope you can pinpoint the problem. Please provide a backtrace pointing at fugit or a way for me to reproduce the issue (and then fix it).

Best regards.

[rafarosa92]

Apparently the error is only within my project, because when I do the test by irb the methods work normally. I'll see what can be, we can close this topic.

Thanks for help!!

You're welcome. If you spot anything else related to fugit, please open a new issue.
