Invalid retry and compile error (SyntaxError)!

Hey all, just a quick note that we're redoing the Ruby curriculum and fixing this!

same issue here (v 2.0.0 / Win 8). Code:

animals = %w(dog cat horse parrot goat shrimp snail cow)
count = 0

for animal in animals
    puts "The current animal is #{animal}"
    break if count == 10
    count += 1
    retry if animal == 'horse'
end

Hi all,

Fyi, I found that statement...

"Inside a rescue block is the only valid location for retry, all other uses will raise a SyntaxError."

...Here.

Looks like the Begin/Rescue block is the only way to use Retry now.

I tried the following code and get the expected result :

animals = %w(dog cat horse goat snake frog)
count = 0

begin
    animals.each do |animal|
        puts "The current animal is #{animal}"
        break if count == 10
        count += 1
        raise if animal == 'horse'
    end
rescue
    retry
end

The following could have worked as well :

animals = %w(dog cat horse goat snake frog)
count = 0

begin
    for animal in animals
        puts "The current animal is #{animal}"
        break if count == 10
        count += 1
        raise if animal == 'horse'
    end
rescue
    retry
end

Hope this helps.

PS : I'm using Ruby 2.1.3

Hi Dongju Seo can you give us any more information about what you're working on? Perhaps paste some code here or a link to the code challenge?

I am having the same issue..my input is nearly identical to Mikal Chawdry's version above. There are slight differences- and I do not have enough experience to recognize whether or not these differences matter- so I have pasted my input below. Also, I am using ruby 1.9.3p448 and textmate v2.0. Here are the contents of loops-11.rb (my textmate file that I am running on ruby):

animals = %w(dog cat horse goat snake frog)
count = 0

for animal in animals
  puts "The current animal is #{animal}"
  break if count == 10
  count += 1
  retry if animal == 'horse'
end

When I run ruby loops-11.rb in the terminal, I receive the following:

loops-11.rb:8: Invalid retry
loops-11.rb: compile error (SyntaxError)

As noted in previous answers, the redo command works as expected. When I edit loops-11.rbso that retry is replaced with redo, I get:

The current animal is dog
The current animal is cat
The current animal is horse
The current animal is horse
The current animal is horse
The current animal is horse
The current animal is horse
The current animal is horse
The current animal is horse
The current animal is horse
The current animal is horse

However, since redo and retry aren't interchangeable, this is not a solution. Guess I'll move on to the next video for now.

bump, same here.

The user "xclite" on dreamincode.net posted this response which I found helpful:

That answers the question. Retry was changed in Ruby 1.9 to only work on a rescue clause - you can only use it to "retry" a begin end block that has failed. For example:

x = 1 begin puts "hello" raise "CRAP" if x == 1 rescue Exception x = 2 retry end

Same stuff here, redo works, retry don't!

U update the video but didnt delete the other, still the bug!!!

Still no update!!! same error:

Invalid retry
compile error(SyntaxError)
