How do I return early from a rake task?
rake, ruby
Solution
A Rake task is basically a block. A block, except lambdas, doesn't support return but you can skip to the next statement using `next` which in a rake task has the same effect of using return in a method.
task :foo do
puts "printed"
next
puts "never printed"
end
Or you can move the code in a method and use return in the method.
task :foo do
do_something
end
def do_something
puts "startd"
return
puts "end"
end
I prefer the second choice.
Problem
I have a rake task where I do some checks at the beginning, if one of the checks fails I would like to return early from the rake task, I don't want to execute any of the remaining code. I thought the solution would be to place a return where I wanted to return from the code but I get the following error ``` unexpected return ```
