Hi,

I want to write an installer, which checks, if sth. is present on the
target system and if not, the installer will install it. For example,
the installer checks if zip is installed.

So I have tons of check functions and corresponding install funtions:

def check_zip
  ...
  return true / false
end

def install_zip
  ...
  system(apt-get install zip)
end

My idea is to use an array, which contains the result of the checking
process
array= [zip, ...] means, that we have to install zip. Is it possible to
"connect" it
to the corresponding install function?

for each element in array
  call install_ array[index]
end


Thanks.

Best regards,

Tomas
