This will print all the debug information at compile time, which is
usually not what you want. I have a little macro I use called ?, which
looks like:
(defmacro ? [x]
`(let [x# ~x]
(prn '~x '~'is x#)
x#))
You could add file and line information to this fairly simply:
(defmacro ? [x]
(let [line (:line (meta &form))
file *file*]
`(let [x# ~x]
(println (pr-str '~x) "is" (pr-str x#)
(str "; (" ~file ":" ~line ")"))
x#)))
And use it like so:
user> (let [x 10]
(+ 5 (? x)))
x is 10 ; (NO_SOURCE_FILE:1)
15
