Subject: Re: Passing all parameters to a method with a unique variable

Hi Mario,

> I'm trying to pass to a method all the parameters in a global variable:

To answer your question:

$allparameters=["dos","ie","4","alone","","8"]

and

$allparameters="dos","ie","4","alone","","8"

does the same - it assigns the array ["dos","ie","4","alone","","8"] to 
the global variable $allparameters.

After this, you want

myclass.mymethod(*$allparameters)

The problem is that myclass.mymethod expects 6 parameters, whereas you 
pass in an array containing 6 things (but that's still 1 parameter, no 
matter how much of what it contains). The splat or unnarray operator (*) 
splits it up into 6 pieces which is what your function wants.

I am quite sure that more people will join this thread, so I am leaving 
the "never use global variables", "using 6 unnamed params is probably 
not a very good idea", "allparameters is not the Ruby way to name a 
variable" style comments to them :-)

Cheers,
Peter
