Can't seem to modify .xls file

[ghost]

Hello!

I'm new to Clojure so I'm sure this is my fault but I'm just kind of too clueless to figure out what might be causing it.

Right now I have two simple functions for testing reading/writing for an excel file.

(defn a []
  (let [workbook (load-workbook "/home/ubikation/src/clojure/excel-test/products.xls")
        a1 (-> workbook (.getSheetAt 0) (.getRow 0) (.getCell 0))]
    (set-cell! a1 "foo")
    (println (.getStringCellValue a1))))

(defn z []
  (let [workbook (load-workbook "/home/ubikation/src/clojure/excel-test/products.xls")
        a1 (-> workbook (.getSheetAt 0) (.getRow 0) (.getCell 0))]
    (println (.getStringCellValue a1))))

The first one works, and prints "foo" but the second one will always return the initial value of the xls file.

Perhaps there is a non-local file bind? I'm not really sure what's going on or how to figure out what I'm doing wrong.

Sorry if this is the wrong location for this.

Sorry, turns out I forgot to save the workbook:

(defn a []
  (let [workbook (load-workbook "/home/ubikation/src/clojure/excel-test/products.xls")
        a1 (-> workbook (.getSheetAt 0) (.getRow 0) (.getCell 0))]
    (do (set-cell! a1 "foo")
        (save-workbook! "/home/ubikation/src/clojure/excel-test/products.xls" workbook))))
