Hello everybody,
I just wrote a simple macro for debugging the ->> .. just thought of
sharing it with you all
(defmacro print-and-return
([x]
`(let [x# ~x]
(println x#) x#))
([flag x]
`(let [flag# '~flag
x# ~x]
(println flag#)
(println x#)
x#)))
(defmacro ->>d [ & args]
`(->>
~@(interpose 'print-and-return args)
print-and-return))
(defmacro ->>dd [& args]
`(->> ~@(interleave args (map (fn [x] (list 'print-and-return x)) args))))
;--------------------------
(->>dd (range 10) (map inc) (filter even?))
(range 10)
(0 1 2 3 4 5 6 7 8 9)
(map inc)
(1 2 3 4 5 6 7 8 9 10)
(filter even?)
(2 4 6 8 10)
;-------------------------------------
(->>d (range 10) (map inc) (filter even?))
(0 1 2 3 4 5 6 7 8 9)
(1 2 3 4 5 6 7 8 9 10)
(2 4 6 8 10)
;----------------------------------
would love to see some of the other macros that you all have written to
enable debugging.. :)
thanks,
Sunil.
