I can't decide if it's a +1 or -1 yet..But here's what I have to say I tend to like 0-based, since it's something that's taught to you as a programmer. So when I first worked with tables and thought table[0][0] would give me the first cell (which errored out..it kinda threw me off a bit). On one hand it makes sense (table wise) to start indexing at row 1 and column 1, on the other hand it's like a 2D array which should have the same indexing as any other array, starting at 0.
I guess having it 0-based will prevent any other incompatibilities such as the .times do|x| as above. Having said that, my indecisiveness is now leaning more towards +1...although it might mean some script changes to reflect my table *for loops* starting at index 1 :) Shao On 8/19/05, Jonathan Kohl <[EMAIL PROTECTED]> wrote: > Consistent 0-based counting is my preference. > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] On Behalf Of Bret > > Pettichord > > Sent: August 19, 2005 1:07 PM > > To: [email protected] > > Subject: RE: [Wtr-general] finding text in a cell that > > containsaspecified image? > > > > Should i read this as +1 for changing to 0-based indexing in > > watir?
