Error: uninitialized constant Bignum (NameError)

[trevor]

Related to: relevance/edn-ruby#39

The edn gem dependency relies on the Ruby Bignum class. This has been deprecated for some time and has now been removed from Ruby 3.2.

Loading edn_turbo now results in an error. Is there any possible workaround?

Unfortunately, I'm not sure what can be done on my end. Someone needs to take ownership of edn-ruby as it seems relevance (cognitect) have completely dropped supporting it. I'm not sure how easy that is on the rubygems side, though?

Alternatively, an option might be to inherit edn-ruby into the edn_turbo source and turn it into its own gem? I have no idea how that may break things for people upgrading however. I also don't do much work on Ruby these days but, if several folks seem interested in doing something like this, I'd be happy to help with the migration and release.

If https://github.com/relevance/edn-ruby can no longer be maintained, then I suppose a fork may be needed and a new Ruby Gem built.

As you suggest inheriting edn-ruby into the edn_turbo source may also be a path forward.

I've sent an email to @russolsen hoping he may be able to weigh in on this.

If the edn-ruby repo can be updated, I'm guessing relevance/edn-ruby#47 may be the fix.

ping @caleb

A drop-in replacement has been created. The new gem is edn2023.

The only update needed on your part is in edn_turbo.gemspec. Change:

 s.add_runtime_dependency('edn', '~> 1.1')

To:

 s.add_runtime_dependency('edn2023', '~> 1.1')

You may also want to update the "Dependencies" section in README.md.

See:

• https://rubygems.org/gems/edn2023
• https://github.com/edn2023/edn2023

Thank you for your help!

I'm getting a 404 on that repo

[trevor]

Thanks for catching that. Repo has been made publicly visible.
