如果满足给定条件,则结束ruby程序

Question

基本上,我只是试图阻止程序运行其余的行,如果满足某个条件.

unless raw_information.first
  puts "No results were returned for that query"
  break
end

但是,在程序运行之前我得到了这个错误:

无效的中断编译错误(SyntaxError)

这样做的正确方法是什么？

Answer 1

abort("No results were returned for that query") unless condition

要么

unless condition
  abort("No results were returned for that query")
end
