我正在尝试编写一个小插件来删除当前文件并关闭活动视图.出于某种原因,self.view.file_name()始终返回None.

我是Python的新手,我不知道为什么它不能像这样工作.根据API参考 file_name()返回当前视图的文件名.

import sublime, sublime_plugin, send2trash

class DeleteCurrentFileCommand(sublime_plugin.TextCommand):
    def run(self, edit):        
        f = self.view.file_name()
        if (f is None):
            return

        send2trash.send2trash(f)
        self.view.window().run_command('close')

dir的输出(self.view):
