[DRE-maint] Bug#888146: ruby-autoparse: FTBFS on ruby2.5: undefined method `[]' for 3.14:Float

[Chris West (Faux)]

Source: ruby-autoparse
Version: 0.3.3-2
Severity: important
User: debian-ruby at lists.debian.org
Usertags: ruby2.5

Dear Maintainer,

This package fails to build against ruby2.5. Soon, there will
be a transition to ruby2.5, and this package will FTBFS in sid.

There may be some details on the wiki about common problems:

Deprecation Warnings:

via the `failure_message` and `failure_message_when_negated` methods.

Too many similar deprecation messages reported, disregarding further reports. Pass `--deprecation-out` or set `config.deprecation_stream` to a file for full output.

Using `should` from rspec-expectations' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` with `config.expect_with(:rspec) { |c| c.syntax = :should }` instead. Called from /build/ruby-autoparse-0.3.3/spec/autoparse/instance_spec.rb:31:in `block (2 levels) in <top (required)>'.


If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

Failures:

  1) AutoParse::Instance with the node schema should not accept an invalid node input
     Failure/Error: if data['$ref']
