ABCLでApache POIを使う

ABCLはJVM上で動作するCommon Lisp処理系なので、Javaのライブラリが利用できます。

(require :abcl-contrib)
(require :abcl-asdf)

(asdf:defsystem apache-poi
  :components ((:mvn "org.apache.poi/poi/3.8")
               (:mvn "org.apache.poi/poi-ooxml/3.8")))

(asdf:load-system 'apache-poi)

(defpackage :test-poi
  (:use :cl :jss))

(in-package :test-poi)

(defun create-9x9 (path)
  (let* ((wb (new 'xssfworkbook))
         (sh (#"createSheet" wb)))
    (dotimes (i 9)
      (#"createRow" sh i))
    (dotimes (i 9)
      (dotimes (j 9)
        (#"setCellValue" (#"createCell" (#"getRow" sh j) i)
                         (format nil "~A" (* (1+ i) (1+ j))))))
    (#"write" wb (new 'fileoutputstream path))))

(create-9x9 "test.xlsx")
