Cute! Though I've spent a lot of time over the last 6 months reading about and toying with clojure, I've not yet found the time to write anything even as substantial as this. I did however take a quick look at the code, and it seems reasonably easy for a noob such as myself to follow. That said, it did remind of something I was meaning to ask which concerns large function definitions (here and elsewhere e.g. clojure.core). Your parse-code function definition seems quite long and it seems counter to the way I think I would write this program; as I would be inclined to write lots of smaller functions responsible for emitting the different spans for comments, strings, etc; and then tie them up into a larger function. That way I could evaluate them all separately and combine them later. I have seen similar large functions elsewhere e.g. a few in clojure.core, and my question is: How do you go about writing a large function like this? What is the process involved? I realise referential transparency means that almost every s-exp is evaluatable separately (providing the necessary bindings are in scope) but is it not a hassle to build such things? How is it you compose a large function and get the benefits of the REPL and lisps interactive development model? Do you evaluate these snippets in a let bind? If so what tools support this? I'm also curious as to what the pro's are in writing large functions like this. There are several in clojure.core, I think gen-class is the one that springs to mind; why is this not defined as a series of smaller functions? Thanks again for the HTML pretty printer!
