Exit code from with Ruby + rest client

Question

I learning ruby and playing it with restsclient I have following test the code and I'm expecting that to return 1/false. I can't seem to make it work.

n@lap-jta102:~/tsamcode$ ./get.rb
n@lap-jta102:~/tsamcode$ echo $?
0 

#!/usr/bin/env ruby

require 'rest_client'
require 'json'

begin
response = RestClient.get("https://admin:[email protected]/isam/host_records/187.0.0.1/hostnames", :content_type => :json, :accept => :json)
return true if response.code == 200
rescue => e
return false unless response != 200
end

$? is not set by return, but by exit. In fact, your return doesn't even do what you think. Try just this:

# one-returner.rb
return 1

$ ruby one-returner.rb
one-returner.rb:1:in `<main>': unexpected return (LocalJumpError)

The reason you're not getting an error in your program is the fact that you blanket-rescue this error when raised by return true (since you have an unrestricted rescue, which is a bad practice for exactly this reason, it can catch a wrong thing and leave you puzzled), and return false never executes (and thus never raises an error) due to unless.

Thank you for the answer. I found out about exit & exit!. I modified the it now the code that it after the rescue it will exit! and seems doing that I expected, but I guess not the way to do it.
