I am still having difficulties with this, so let me clarify by showing some
sample code.
My fn looks like this:
(defn report [text]
(str
"string1"
"string2"
(apply str (map-indexed (fn [idx itm] (time-text idx itm)) (filtered-list
text))))))
When I invoke spit in order to output a text file using the above funtion,
I only get the first item in my list (filtered-list text) outputted
Here is the basic code for my fns used above:
(defn filtered-list [text]
(let
[street (:str (address text))
city (:city (address text))
state (:state (address text))
;actually there's a bunch of other bindings, 3 will suffice for the example
]
(remove nil?
(conj '()
(if-not
(blank? street)
(str "ADDRESS: " street))
(if-not
(blank? city)
(str "CITY: " city))
(if-not
(blank? state)
(str "STATE: " state))))))
(defn time-text [time-idx text-var]
(str some-string (hour-min time-idx) another-string))
;this uses the clojure time library
(defn hour-min [idx]
(format-local-time (plus (local-now) (minutes idx)) :hour-minute-second))
