I've always loved to play with editors. Over the past few days, I have been playing with a simple editor that excels at one thing: code folding. I've never been much for code folding, but I have to admit that this editor may have just changed my mind about that. See, the mapping I can get from this editor to the eventual output I want in my literate programs is quite amazing, and it really makes editing my literate WEBs that much more enjoyable. Just take a look at this screen shot of my editing session on my latest version of ChezWEB.
