在这篇blog之前写过同类的校验JS代码工具：JavaScript Lint 的在 Notepad++ 中如何使用，google 提供的 Closure Linter 给了我们更多的工具选择。

Closure Linter是在Python上运行的，所以先在系统中配置安装Python的运行环境：

  1. 安装 Python。本人安装的版本为 Python 2.5.4
  2. 安装 Easy Install 模块。也就是要安装 setuptools windows下本人安装的为: setuptools-0.6c11.win32-py2.5.exe
  3. 确保 Easy Install 配置到Path环境变量。

然后，在命令行中执行如下命令：

easy_install E:\closure_linter\closure_linter-2-1.2.6.tar.gz

如果出现啪啦啪啦如下的截图画面：

则说明Closure Linter 安装成功！OK，在Notepad++ 的NppExec执行如下命令：

gjslint --strict $(FULL_CURRENT_PATH)

可以将这个命令保存为 Closure Linter。点击“OK”试试，如果在控制台窗口输出如下结果：

gjslint –-strict D:\work\js\WOYO\event.js

Found 129 errors, including 0 new errors, in 1 files (0 files OK).Some of the errors reported by GJsLint may be auto-fixable using the script
fixjsstyle. Please double check any changes it makes and report any bugs. The
script can be run by executing:fixjsstyle –-strict D:\work\js\WOYO\event.js<<< Process finished.
================ READY ================

则说明JS代码已经被 Closure Linter工具校验。居然这么多 bug！不过，修复 bug 也可以利用工具来完成，哈哈！执行如下的命令即可：

fixjsstyle –-strict $(FULL_CURRENT_PATH)

在Console窗口中显示的结果：

fixjsstyle –-strict D:\work\js\WOYO\event.js
Process started >>>
Fixed 44 errors in D:\work\js\WOYO\event.js
<<< Process finished.
================ READY ================

129个bug修复了44个!因为选择了strict参数，果然很严苛！哈哈！
