优化从excel文件读取到clojure中的记录

Question

从excel文件中读取特定行数并在记录中更新它们的最佳方法是什么，每行都是记录的新实例

Answer 1

简单的方法是将excel文件保存为csv文件，然后应用通常的tools

(defrecord Record [W1 W2 W3])

(defn read-csv [fname count]
  (with-open [file (reader fname)]
    (doall (take count (map (comp first csv/read-csv)
                            (line-seq file))))))

(map #(apply ->Record %) (read-csv "1.csv" 3))
->(#Record{:W1 "1", :W2 "one", :W3 "A"}
   #Record{:W1 "2", :W2 "two", :W3 "B"}
   #Record{:W1 "3", :W2 "three", :W3 "C"})

Answer 2

我可能会使用Martin Jul的docjure。
