import sublime, sublime_plugin
class ExampleCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.insert(edit, 0, "Hello, World!")view.run_command('example')
这个时候注意观察当前的文件开头插入了“Hello,World”,当前文件也变成待保存的状态，好了，测试成功，我们按ctrl+z，让它回到开始的状态的吧。等等，为什么是“example”?它是从前面插件例子里
class ExampleCommand 来的，你需要换一个属于你自己插件的名字，把ExampleCommand里的‘Example’改一下。这一改，然后有的人发现运行自己的插件名称运行不了了，原来这里的设置有个规则，你用驼峰命名，例如PxToRemCommand 你运行的时候需要是view.run_command(‘px_to_rem‘)，即用下划线隔开，否则像例子那样好了，开头大写后面全是小写。第三步设置快捷键[
{
"command": "px_to_rem",
"keys": [
"ctrl+alt+k"
]
}
]
view.run_command(‘px_to_rem‘)，你可以改成不会冲突的别的按键，试试看看生效了没。第四步就是编写程序1、从设置文件里读取信息，之前同事写的是json格式的，很熟悉呀{
"files": ["./test/style.css"],
"root_value": 20,
"unit_precision": 5,
"prop_white_list": ["width", "height", "padding", "padding-top", "padding-right", "padding-bottom", "padding-left", "margin", "margin-top", "margin-right", "margin-bottom", "margin-left"],
"replace": false,
"media_query": false
}保存。然后我们到之前我们建的插件文件text.py里去试试看能不能获取到我们的设置信息。import sublime, sublime_plugin
SETTINGS_FILE = "px_to_rem.sublime-settings"
class PxToRemCommand(sublime_plugin.TextCommand):
def run(self, edit):
#load config
settings = sublime.load_settings(SETTINGS_FILE)
#file
files = settings.get("files");
print files我们先用sublime.load_settings()把设置文件引入，然后用settings.get()去取我们想要的属性。最后用print
打印到控制台。然后我们用crtl+`打开控制台，然后我们运行我们的插件ctrl+alt+k，看看打印出我们想要的东西没。<pre name="code" class="python">prop_white_list = settings.get("prop_white_list",[])for text in prop_white_list:
