I think being consistent everywhere would be a good thing. If that means being consistent with Ruby and starting at 0, then so be it. Personally, I think the person who first coded programming/scripting languages to start counting at 0 should have had his/her head examined and then been committed to an insane asylum. I've learnt many programming languages over the years and even once sat and painfully read through a series of programming language manuals as long as a desk shelf back almost 20 years ago. I still recall how that language was hailed as a Fourth-Generation Language that was supposed to make programming easier because the syntax and vocabulary (commands, methods, etc) were closer to more natural language. It seemed ironic that the easier the language was supposed to be, the more manuals were required to teach you how to program in it. The point here is that it is natural for human beings to start counting at 1. I have never in my entire life ever heard anyone start counting at 0. *That* is stupid. So, Paul, how many children do you have? Well, my first boy would be 0, and my second son would be 1, so I guess I have 1 child. Even the Cat in the Hat's best friends are Thing 1 and Thing 2. I would have like to have heard Dr. Seuss' thoughts on the topic of counting. If machines can't be made to speak *our* language, then they're not very useful. Forcing people to think and code in that way is an impediment to clear, human thought IMHO. In the absence of something good, I'll take something consistent. The enemy you know and all that, right? If you want to attract non-programmers to the use of the tool, then you will have to appeal to them in a friendly, non-programming way. (That would include not forcing them to rethink how to count because that's not a friendly thing to do.) I recall Gracie Hopper once saying that if you hear the phrase that's the way it's always been done then you know it's time to change it. Well, you asked for my thoughts. ;-) Thanks for asking. Let me just put this soapbox away for now.. ;-) Cheers. Paul C. ___ Wtr-general mailing list Wtr-general@rubyforge.org http://rubyforge.org/mailman/listinfo/wtr-general

do we have the ability to vote 'Yes - with no backwards compatability' 'Yes - with backwards compatability' or 'No' or just yes or no Ive just grepped my code and found 196 occurrances of :index :-( Paul - Original Message - From: Bret Pettichord [EMAIL PROTECTED] Date: Wednesday, January 24, 2007 2:40 pm Subject: Re: [Wtr-general] undefined method `[]' for nil:NilClass (NoMethodError) error at the end of array???

Vote for the one you want. Without backwards compatibility http://jira.openqa.org/browse/WTR-135 With backwards compatibility http://jira.openqa.org/browse/WTR-134 But realize that if you vote for this ticket, that means that you don't want 0-based indexing in Watir ever unless it has backwards compatability. In other words, it is probably a no. Bret ___ Wtr-general mailing list Wtr-general@rubyforge.org http://rubyforge.org/mailman/listinfo/wtr-general

For some reason i'm getting the following error at the end of the loop,
any idea WHY???
0.upto (t.length-1) { |x|
puts t[x][0]
}
should do it, but I think you figured that out.

This is one of those times when I'll never understand why some things in
programming start counting at 1 and some things start counting at 0.
I, too, have several similar loops in some of my scripts, but I opted for
the more readable format of saying:
t.length.times { |x|
puts t[x][0]
}
I just can't be bothered with loops like 1.upto(t.length) {|x| puts x}
which, technically, counts from the first item to the last item, but
really x starts counting at 0 and goes to (length - 1). This might be
convenient if you are working with arrays but not a whole lot else.

This is largely because Watir is stupid in this area. We made a bad
design choice with Watir 1.0. We'd now like to make Watir consistent and
start with 0 everywhere (like everything else in Ruby) but this would
raise compatibility issues. We welcome your thoughts in this area.

Another way to say this is:
t.each {|x| puts x[0]}
