从位于非标准目录中的文件中获取设置值

Question

我有这样的 Sublime 目录结构：

Packages
   |-- Foo
   |    |-- Markdown.sublime-settings
   |
   |-- Bar
   |    |-- plugin.py
   |
   |-- User
        |-- Markdown.sublime-settings

然后，我尝试获取 wrap_width 值，存储在 Foo/Markdown.sublime-setting 中。出于某种原因，load_setting 方法似乎不起作用，尽管 save_settings 工作正常。

import sublime
import sublime_plugin

class MarkdownSettings(sublime_plugin.EventListener):
    def on_activated(self, view):

        path = view.file_name()
        if path:

            e = view.file_name().split('.')[1]
            if e == ("md" or "mmd"):

                # Simple test. It works
                x = sublime.load_settings("Markdown.sublime-settings")
                wrap_width = x.get("wrap_width")
                print(wrap_width) # Prints 50

                # If I change directory to "../Foo", `load_setting` method would not work
                x = sublime.load_settings("../Foo/Markdown.sublime-settings")
                wrap_width = x.get("wrap_width")
                print(wrap_width) # Prints None

                # The code below is added just for demonstration purposes,
                # to show that `save_setting` method works fine.
                x = sublime.load_settings("../Foo/Markdown.sublime-settings")
                x.set("wrap_width", 20)
                sublime.save_settings("../Foo/Markdown.sublime-settings") # File updated

如何获取存储在 Foo/Markdown.sublime-settings 中的 wrap_width 值？

不支持使用带有 load_settings 的路径。

来自http://www.sublimetext.com/docs/3/api_reference.html#sublime：

Loads the named settings. The name should include a file name and extension, but not a path. The packages will be searched for files matching the base_name, and the results will be collated into the settings object. Subsequent calls to load_settings() with the base_name will return the same object, and not load the settings from disk again.

如果你真的需要这样做，你应该使用sublime.decode_value(sublime.load_resource('Packages/Foo/Markdown.sublime-settings'))。
