Catch throw?

ruby-talk
1

Hello,

I just started using catch and throw. Therefore this question might be an
easy one.

I have multiple ruby files. In one of the files I like to throw and then in
the main function in a different file I like to catch the throw. Is this
possible or do throw/catch need to be in the same file?

Example:
fileOne.rb

def somefunct
....
throw :quit_script
....
end

fileTwo.rb
catch :quit_script
...
end

Thx,
Bernd

They have to be in the same call chain.

so if fileTwo require's fileOne.rb and fileTwo's code looks like
catch :quit_script do
    ...
    somefunct()
   ...
end

it will work
