Clojure Read a File as a Sequence of Lines

Clojure把檔案逐行讀成sequence

Clojure (Lisp) 常用到sequence，讀檔時也可以把檔案逐行讀成sequence：

1

(line-seq (clojure.java.io/reader (clojure.java.io/file "file-path")))

讀出來的東西類似像這樣：

1

("line-1" "line-2" "line-3" "line-4" "line-4")

讀成sequence之後就可以用doseq之類方便處裡sequence的macro來操作它，例如：

1
2

(doseq [line (line-seq (clojure.java.io/reader (clojure.java.io/file "file-path")))]
  (println line))
