@mariochavez Also -- would it be possible to relax the Ruby version requirement for those installing the gem with an earlier Ruby version? https://github.com/mariochavez/chroma/blob/main/chroma-db.gemspec#L15

I'd recommend going down to ">= 2.6.0"

[mariochavez]

Hi!

The gem uses the newest Ruby syntax; it will not work with Ruby 3.1 or older. Needs 3.2 or better.
Changing the gem code to relax the Ruby version means a rewrite of this gem.

I'll try to add Ruby Next to polyfill the newest syntax to older Ruby, but I can't make any commitment that this will work.

I'm releasing a new version of this gem. It uses ruby-next to provide backward compatibility with older versions of ruby down to 2.7.8

Wow @mariochavez, incredible job! Thank you so much for knocking this out so quickly!

[mariochavez]

Closing this for now.

[andreibondarev]

@mariochavez I'm up and running! Thank you sir!

[andreibondarev]

@mariochavez It's integrated into langchain.rb now: patterns-ai-core/langchainrb#20

[mariochavez]

@andreibondarev awesome!
