Looks nice.
Have you considered submitting pages like these to the clojure-doc.org site? I
don't know if Michael Klishin would be interested in this material, but it
certainly wouldn't be out of place there if he was willing to take it.
There is a much shorter list of examples here that I wrote a while back:
http://clojuredocs.org/clojure_core/clojure.pprint/cl-format
Regarding the leading zeroes *before* a minus sign for negative numbers, e.g.
like this (last example from the page above):
;; This might look like a bug, but it is actually behavior specified by the
;; Common Lisp HyperSpec mentioned in the docs above. If you don't want that
;; behavior (format "%08d" -2) might suit your purposes better.
user=> (cl-format nil "~8,'0d" -2)
"000000-2"
As the comment above says, the Common Lisp HyperSpec really does specify that
behavior. In particular, read this page word-for-word and you'll see what I
mean:
http://www.lispworks.com/documentation/HyperSpec/Body/22_cbb.htm
It sounds silly to me, but I've verified that several Common Lisp
implementations behave this way. If you want leading zeros for negative
numbers, don't use cl-format.
