Incorrect date parse

[MeterSoft]

[10] pry(#)> Chronic.parse("4/30")
=> Mon, 30 Apr 2018 12:00:00 PDT -07:00
[11] pry(#)> Chronic.parse("4/31")
=> nil
[12] pry(#)> Chronic.parse("4/32")
=> Fri, 16 Apr 2032 00:00:00 PDT -07:00

In last example should be nil

[davispuh]

It's fixed in my unfinished rewrite branch.

@davispuh yes, this branch works with my example but has many another issues.
Example
[5] pry(Order)> Chronic.parse("1/1/18")
=> Mon, 01 Jan 2018 12:00:00 PST -08:00
[6] pry(Order)> Chronic.parse("01/1/18")
=> Thu, 18 Jan 2001 12:00:00 PST -08:00
[7] pry(Order)> Chronic.parse("1/01/18")
=> Mon, 01 Jan 2018 12:00:00 PST -08:00
[8] pry(Order)> Chronic.parse("11/01/18")
=> Tue, 18 Jan 2011 12:00:00 PST -08:00

[davispuh]

That's kinda expected behavior. There are 3 different ways how to interpret it and it just guesses it as best as it's possible.

In lib/chronic/definition.rb
you can see there is

[[ScalarYear, SeparatorSlash, ScalarMonth, SeparatorSlash, ScalarDay], :handle_sy_sm_sd],
...
[[ScalarMonth, SeparatorSlash, ScalarDay, SeparatorSlash, ScalarYear, [SeparatorDot, Scalar, :none]], :handle_sm_sd_sy],
...
[[ScalarDay, SeparatorSlash, ScalarMonth, SeparatorSlash, ScalarYear, [SeparatorDot, Scalar, :none]], :handle_sd_sm_sy],

it is possible to set default format %m%d%y ?

[davispuh]

Default I don't think so. But you could remove other formats with monkey patching.

Anyway firstly you need to pass :endian_precedence => [:middle] so it doesn't use dd/mm/yy and then to remove other formats

class Chronic::DateDefinitions
  def definitions
    []
  end
end

class Chronic::ShortDateDefinitions
  def definitions
    []
  end
end

class Chronic::DateTimeDefinitions
  def definitions
    []
  end
end

it is possible to fix reported issue in this master branch?

[davispuh]

It will be fixed when rewrite branch will be finished and merged in master.
