mac下一个处理plist文件的工具位于
/usr/libexec/PlistBuddy 工具


查看plist文件中的某一项内容时就可以

 /usr/libexec/PlistBuddy -c print:CFBundleShortVersionString plistname

就可以打印出相印工程的版本号

Vim as a PHP IDE
This Vim configuration is meant to be used to make Vim act more like an IDE. I use it mostly under MacVIM, so some things may be weird in different environments. For now, I'm just planning on using github to make managing my VIM configuraiton more easy, especially with deploying it to different environments. I'm not sure if I will make this a community projects.

I do use this configuration on Linux while running plain vim, and it works fine for the most part.

只有模板变量，字符串，整数和小数可以作为 {% ifequal %} 标签的参数。下面是合法参数的例子：

{% ifequal variable 1 %}
{% ifequal variable 1.23 %}
{% ifequal variable 'foo' %}
{% ifequal variable "foo" %}

其他任何类型，例如Python的字典类型、列表类型、布尔类型，不能用在 {% ifequal %} 中。 下面是些错误的例子：

{% ifequal variable True %}

总结一下：

进来的请求转入/hello/.

Django通过在ROOT_URLCONF配置来决定根URLconf.

Django在URLconf中的所有URL模式中，查找第一个匹配/hello/的条目。

如果找到匹配，将调用相应的视图函数
