debux VS spinneret

The `let` binding is local, so it's referring to clojure.core/+, and outside the function `add` I can use the name `add` to call it. Seems it's handling that case correct?

I think debuggers tend to be used as a library across many different editors, rather than the editor/plugin providing that functionality. Personally, I don't use debuggers much as the functions I write tend to be small and evaluating small executions with the repl tends to reveal the issue quickly. Sometimes when refactoring others code I've used https://github.com/philoskim/debux to various degrees of success.

I do think cider (https://github.com/clojure-emacs/cider) has stuff regarding stepping debuggers, but I'm not sure how common it is to use it. Maybe other Clojure users can fill me in :)

Yeah, as you said, the Java ecosystem basically covers that. For OSS stuff, I use VisualVM, and for professional stuff I use YourKit, both of them work well with Clojure and points out my user-space code with ease. And I've never been paid anything for actually writing/maintaining Java code, so even with that, seems I'm able to use those tools just for Clojure :)

Ah yes, of course. The condition system and restarts :) Thanks!

To debug a threading macro you definitely should take a look at debux https://github.com/philoskim/debux .

Really cool! I've used https://github.com/philoskim/debux for somewhat similar(nested prns); I find the horizontal UX quite interesting.

Thirteen Letters - front end uses parenscript, spinneret, and cl-css; back end uses hunchentoot/hunchensocket

That looks more like an Emacs Lisp equivalent to CL's Spinneret than a renderer. Quite nice, but also not quite the same use-case.

Obviously this is a contrived example, but the point is that I want to generate HTML from a list. I don't care about compiling, DSLs or templates, just a plain nested list. Spinneret seemed like it would fit the bill because it has the function interpret-html-tree, but then the author made the entire library only work with a set of hard-coded tags, so if my list contains the math tag (which is a standard HTML5 tag) everything fails.
