About Ruby error 'kEnd' ?

Question

I'm having a lot of trouble with Ruby after coming back to it from a long break.

I'm getting a lot of 'unexpected kEND' errors, and I've tracked it down to lines below. I'm not having trouble with a particular piece of code, but rather, the concept of 'unexpected kEND' .

if (condition)
  do-one-line-thing()

and

# inside of a loop...
if ( condition-evaluation-that-might-cause-error-during-run-time )
  do-something()
end

and

myarray.each { |element|
   do-soemthing-that-might-cause-error-during-run-time-for-some-but-not-all-values()
}

Question :

What other things can cause these kEND errors ? It seems like kEND is being used as a general "Badness on line ##" error? What can you tell me about kEND errors in general?

Answer 1

an unexpected kEND is where the end keyword was found somewhere it shouldn't be.

Generally you've closed too many code blocks, or you've got some other syntax problem.

If you paste a (complete) file which has this problem we can point out the error...

Answer 2

There is a syntax error in the first piece of code

if (condition)
  do-one-line-thing()

You always have to explicitly close the if clause with end. You cannot omit it, like you do in many other languages, even if the block consists of a single line.
