Ranger：如何从commands.py 中提取选定的文件？

我从 arch wiki 复制了这个片段。但它不是提取选定的文件，而是提取拉出的文件。所以我想知道一这两件事：

  1. 如何使用选定的文件而不是提取的文件来制作 extract_here ？

  2. 如何从commands.py中自动提取选定的文件？

    class extract_here(Command):
def execute(self):
    """ Extract yanked files to current directory.
        HOW TO USE: press yy to yank, then call the method
                    with a shortcut or the command itself."""
    copied_files = tuple(self.fm.copy_buffer)

    if not copied_files:
        return

    def refresh(_):
        cwd = self.fm.get_directory(original_path)
        cwd.load_content()

    one_file = copied_files[0]
    cwd = self.fm.thisdir
    original_path = cwd.path
    au_flags = ['-X', cwd.path]
    au_flags += self.line.split()[1:]
    au_flags += ['-e']

    self.fm.copy_buffer.clear()
    self.fm.cut_buffer = False
    if len(copied_files) == 1:
        descr = "extracting: " + os.path.basename(one_file.path)
    else:
        descr = "extracting files from: " + os.path.basename(
            one_file.dirname)
    obj = CommandLoader(args=['aunpack'] + au_flags
                        + [f.path for f in copied_files], descr=descr,
                        read=True)

    obj.signal_bind('after', refresh)
    self.fm.loader.add(obj)
    ```

解决方案：

class extract_here(Command):
def execute(self):
    """ Extract selected files to current directory."""
    import os
    from ranger.core.loader import CommandLoader
    cwd = self.fm.thisdir
    copied_files = tuple(cwd.get_selection())

    def refresh(_):
        cwd = self.fm.get_directory(original_path)
        cwd.load_content()

    one_file = copied_files[0]
    cwd = self.fm.thisdir
    original_path = cwd.path
    au_flags = ['-X', cwd.path]
    au_flags += self.line.split()[1:]
    au_flags += ['-e']

    self.fm.copy_buffer.clear()
    self.fm.cut_buffer = False
    if len(copied_files) == 1:
        descr = "extracting: " + os.path.basename(one_file.path)
    else:
        descr = "extracting files from: " + os.path.basename(
            one_file.dirname)
    obj = CommandLoader(args=['aunpack'] + au_flags
                        + [f.path for f in copied_files], descr=descr,
                        read=True)

    obj.signal_bind('after', refresh)
    self.fm.loader.add(obj)

在 arch wiki 中编辑，希望没有人会再遇到这个问题。
