Phil,
Indeed, clj-backtrace was largely inspired by Rubinius' "Awsome
Backtrace" feature.
I've implemented and pushed to GitHub an experimental implementation
of colorized backtraces for the REPL:
In addition to the usual (pst) to pretty-print the last exception, you
can now (pst+) to colorized-pretty-print it.
The current color scheme:
(defn elem-color
"Returns a symbol identifying the color appropriate for the given trace elem.
:green All Java elems
:magenta Any fn in the user or repl* namespaces (i.e. entered at REPL)
:blue Any fn in clojure.* (e.g. clojure.core, clojure.contrib.*)
:default Anything else - i.e. Clojure libraries and app code."
[elem]
(cond
(:java elem)
:green
(or (nil? (:ns elem)) (re-match? #"^(user|repl)" (:ns elem)))
:magenta
(re-match? #"^clojure\." (:ns elem))
:blue
:else
:default))
