the op cli changed totaly, so this does not work any more.

get your items from 1password in ruby.

require "opr21"

unless ENV.has_key?"ONEPASSWORD"
    puts "env-var ONEPASSWORD is missing"
else
    op = Opr21.new(ENV["ONEPASSWORD"], {:domain => "your-domain", :email => "your-email", :secret => "your-secret"})
    opv = op.getItem "your-item-title"
    puts opv["website"]
end

with the fuction getItemList(titleRegex, vault) you can search for your entry. it returns an array of the entry titles.

just install the gem:

gem install opr21

Download the op commandlinetool for 1password.
