Full docs for my new Ruby gem feelings now available. Most idiomatic and fun way to add decision models to your code

https://t.co/ApWfZGt0ir

feelings: Probabilistic conditionals for Ruby.

Source: https://obiefernandez.com/gems/feelings/ A decision model answers a typed question about a value, with a calibrated probability attached to the answer. feelings lets a Ruby conditional ask one directly.

Feelings(email).like?("genuinely urgent")

Branch on the answer instead of a boolean:

Feelings(ticket).like("this customer is about to churn") do |mood|
  mood.yes   { escalate(ticket) }
  mood.maybe { flag_for_review(ticket) }
  mood.no    { close(ticket) }
end

Or pick the closest match out of a small label set:

Feelings(support_message).most_like(:billing, :bug_report, :feature_request, :spam)
# => :bug_report

• decide: named policy decisions with floors, fail modes, and verdicts.RubyGems
• feelings: this gem, for the questions you would otherwise write as anif.RubyGems

feelings is inspired byProbably, a small language for LLM workflows that showed what code reads like when anifcan ask a decision model a question.
