I needed a simple breadcrumb module/class that would let me set the first crumb and add to it later. I looked at www.ruby-toolbox.com and saw a bunch, none of them looked simple enough for me. I already had a template so I dont care about changing that…so I whipped up my own breadcrumbs:
After watching www.rubytapas.com talk about using Struct (I had never really used it before or understood why not just make a class). At first I defined crumb outside of Breadcrumb, then after I had tests, moved inside and it still worked. It seems a bit odd, to have that inside Breadcrumb, but its only accessible inside Breadcrumb so I guess that is good.
