Sublime Text 自动完成窗口在滚动列表时关闭

最佳解决方案：使用auto_complete_cycle设置（2015 年 3 月 26 日添加）：

请使用这个新的简单解决方案，而不是 python 插件

2015 年 3 月 24 日发布的 Sublime Text 新版本具有一个名为 auto_complete_cycle 的新设置，用于实现此行为。将其设置为 true 可循环访问自动完成结果。

"auto_complete_cycle": true

最糟糕的旧解决方案：这个自定义插件

我刚刚制作了这个插件，它在 Linux Mint 的 Sublime Text 3 上运行良好。我没有在 Sublime Text 2 中测试过它，但我认为插件系统是相同的，所以，它也应该适用于该版本。使用的解决方法不是太漂亮，但有效。

import sublime, sublime_plugin

class UpArrowInAutoCompleteCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.settings().set('autoCompleteFlag',True)
        self.view.settings().set('initialPoint', self.view.sel()[0].begin())

        """ Move one line up """
        self.view.run_command('move', {"by": "lines", "forward": False});
        """ Auto-complete was opened and up arrow was pressed, so if the cursor changes
        (on_selection_modified will be triggered) we have gone outside the list. 
        If we were not in the first element on_selection_modified will not be triggered, so
        we turn of the flag"""
        sublime.set_timeout(lambda: self.view.settings().set('autoCompleteFlag', False),300)


class AutoCompleteSelectionModifiedTriggerCommand(sublime_plugin.EventListener):
    def on_selection_modified(self, view):
        if view.settings().get('autoCompleteFlag'):
            """ If the up arrow was pressed and on_selection_modified 
            has been triggered, then we know that we were in the first element
            of the list and we hitted the up arrow"""
            view.settings().set('autoCompleteFlag', False)
            initialPoint = view.settings().get('initialPoint')

            """ We don't know how many words the auto_complete has, so, 
            in order to calculate that number, we move down in the list
            till we get outside the list. After that we make the list appear
            again and move down n-1 times to go (and stay) to the last line """
            view.sel().clear()
            view.sel().add(initialPoint)
            view.run_command('auto_complete')

            numLines = 0
            while view.sel()[0].begin() == initialPoint:
                view.run_command('move', {"by": "lines", "forward": True})
                numLines += 1
                if numLines == 401:
                    return

            if numLines == 0:
                return

            view.sel().clear()
            view.sel().add(initialPoint)
            view.run_command('auto_complete')

            numLine = 0
            while numLine < (numLines-1):
                view.run_command('move', {"by": "lines", "forward": True})
                numLine += 1

要制作插件，请使用 Tools>new 插件并粘贴代码。然后将其保存在 Packages/User 文件夹中。您可以使用“首选项”>“浏览包”来查找“包”部分，用户文件夹位于其中。

为了使它工作，我在我的用户键绑定文件中添加了这个绑定（第二个是你自己的绑定）：

{
    "keys": ["up"],
    "command": "up_arrow_in_auto_complete",
    "context": [{
        "key": "auto_complete_visible",
        "operator": "equal",
        "operand": true
    }]
}, {
    "keys": ["down"],
    "command": "auto_complete",
    "context": [{
        "key": "auto_complete_visible"
    }]
}

编辑：这是一个示例结果：
