Simply use next
in this context:
$ irb
irb(main):001:0> def thing(*args, &block)
irb(main):002:1> value = block.call
irb(main):003:1> puts "value=#{value}"
irb(main):004:1> end
=> nil
irb(main):005:0>
irb(main):006:0* thing {
irb(main):007:1* return 6 * 7
irb(main):008:1> }
LocalJumpError: unexpected return

from (irb):6
from /home/mirko/.rvm/rubies/ruby-1.9.1-p378/bin/irb:15:in `<main>'
irb(main):009:0> thing { break 6 * 7 }
=> 42
irb(main):011:0> thing { next 6 * 7 }
value=42
=> nil
return
always returns from method, but if you test this snippet in irb you don’t have method, that’s why you haveLocalJumpError
break
returns value from block and ends its call. If your block was called byyield
or.call
, thenbreak
breaks from this iterator toonext
returns value from block and ends its call. If your block was called byyield
