*** premature send ***
Ya know, I've never seen that before but I like it!
I have previously noticed (by accident) that you can have "naked"
expressions in a file/namespace (i.e. not inside of a def/defn). For
example, I use a statement like this:
(ns ...
(:require [tupelo.core :refer [spyx]] ...
(spyx *clojure-version*)
at the top of my main testing namespace tst.tupelo.core to get:
*clojure-version* => {:major 1, :minor 8, :incremental 0, :qualifier
"alpha4"}
printed at the top of every test run. Another favorite is:
(ns ...
(:require [schema.core :as s] ...
; Prismatic Schema type definitions
(s/set-fn-validation! true)
to control Prismatic Schema in each namespace.
I have also used other naked expressions (in both test and regular
files/namespaces) as a kind of free-form scratchpad when experimenting with
new code (since I can type so much faster in the editor than the repl).
Thanks for the suggestion,
Alan
