Support for Ruby2.7?

[utkarsh2102]

Hi,

Ruby2.7 was released in December, 2019. It'd be great if we could have support for that. The build fails against Ruby2.7 with the following log: https://people.debian.org/~kanashiro/ruby2.7/builds/7/ruby-parslet/ruby-parslet_1.8.2-2+rebuild1580882348_amd64-2020-02-05T05:59:10Z.build

The failure is this:

Failures:

  1) Parslet::Slice ('foobar', 40, 'foobar') conversion cast to Integer should fail when Integer would fail on a string
     Failure/Error: lambda { Integer(slice) }.should raise_error(ArgumentError, /invalid value/)
       expected ArgumentError with message matching /invalid value/ but nothing was raised
     # ./spec/parslet/slice_spec.rb:115:in `block (5 levels) in <top (required)>'

A bit more info on Ruby 2.7

ArgumentError: invalid value for Integer(): "foobar"

@balasankarc, hi, It's fixed now. So closing this.
