Ruby Module

Ruby

I have written some of the funcions in a file . The filename is test.rb
Examples
test.rb has only the following functions .
def hai(a,b)
puts “This is Hai”
end

         def hellow
              puts "This is Hellow"
         end

In check.rb I have required test.rb file . Then I used below hai method.
It works .
The check.rb file has
require ‘test’
hai(1,2)

When I running this program in command line it works . But I am calling
check.rb program from perl using system call . Some times it works fine
. Some time It doesn’t work . I got some error in my code . The Error
is ’ Wrong no of argument error’ .
system(check.rb).
I am running above code from perl . To check the problem , I am
redirecting the stderr to a file . I got Wrong ‘no of argument error’ .

check.rb is an executable file .

My Solution
I think that we should not require a file without module . I
request you t share your experience .

Do you have set the shebang line properly? Did you make sure that
your load path is configured in a way that check.rb finds the proper
test.rb?

I am not sure what you are trying to say here but I doubt that this
will solve your issue.

I request you t share your experience .

A better way to put this would have been “please share your experience”.

Can you paste the exact and complete error message you see? This
will make it clear whether the error comes from Perl or Ruby, and if
Ruby, exactly which line it is on.

The only problem I can see is that “require ‘test’” assumes that test.rb
is in the current working directory. Perl may have changed the current
working directory. You could write instead:

require File.join(File.dirname(FILE), ‘test’)
