jsdoc-toolkit

jsdoc-toolkit算是google推薦的JavaScript document generator，您可以在 http://code.google.com/p/jsdoc-toolkit/downloads/list下載。
由於jsdoc-toolkit是用java寫的，所以請先安裝好java，Windows底下執行命令把"/"改成"\"就可以了，執行java -jar jsrun.jar app\run.js -a -t=templates\jsdoc mycode.js就可以產生mycode.js的文件檔了，這部分可以參考裡面的README.txt，預設會將document寫到out目錄中。
手邊剛好有extjs，所以直接拿ext-all-debug.js當測試，卻得到exception from uncaught JavaScript throw: java.lang.OutOfMemoryError: Java heap space的錯誤。這導因於heap不夠，可透過設定Xmx解決(請參考後面說明)。

執行java -jar jsrun.jar app/run.js --help 可以獲取更多資訊。

out of memory.
看到java.lang.OutOfMemoryError就是要加大記憶體空間啦，java 程式有-Xms跟-Xmx參數可以用。
-Xms Setting minimum heap size
-Xmx Setting maximum heap size

心得：感覺jsdoc-toolkit還是很陽春，而且很耗記憶體和CPU，感覺很慢，常常讓人以為當機了。不知道哪邊有像ext-js的document一樣漂亮的工具。
