Sublime text:如何获取当前视图的文件名

Question

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):

Answer 1

根据非官方文档的Plugins页面,Sublime Text以下列方式规范化命令名称:

1. 剥去"Command"后缀
2. 单独的驼峰短语带有下划线

因此,应以下列方式调用DeleteCurrentFileCommand: view.run_command("delete_current_file")

使用此命令,我能够完全按照上面在Python控制台中列出的那样运行您的插件.

但是,如果我尝试运行view.run_command("DeleteCurrentFile"),则控制台将显示一个空行.这可能导致self.view.file_name()返回None的想法.
