如何重制这个 python3 dircache/cmd python3

Question

我想知道如何在 python3 中进行这个简短的测试，cmd 在 python3 中受支持，但 dircache 不...目前仅适用于 python2 但正在寻找将其更改为在 python3 中工作，谢谢！

#!/usr/bin/env python

import cmd
import dircache

class MyCmd(cmd.Cmd):
    def __init__(self):
        cmd.Cmd.__init__(self)
        self.prompt = '(MyCmd)'

    def do_test(self, line):
        print('cmd test ' + line)

    def complete_test(self, text, line, begidx, endidx):
        """ auto complete of file name.
        """
        line = line.split()
        if len(line) < 2:
            filename = ''
            path = './'
        else:
            path = line[1]
            if '/' in path:
                i = path.rfind('/')
                filename = path[i+1:]
                path = path[:i]
            else:
                filename = path
                path = './'

        ls = dircache.listdir(path)
        ls = ls[:] # for overwrite in annotate.
        dircache.annotate(path, ls)
        if filename == '':
            return ls
        else:
            return [f for f in ls if f.startswith(filename)]



if __name__ == '__main__':
    mycmd = MyCmd()
    mycmd.cmdloop()

我试过用这个代替 dircache，但没有成功

@lru_cache(32)
def cached_listdir(d):
     return os.listdir(d)

给你看看加载函数

import os
import glob
import cmd

def _append_slash_if_dir(p):
    if p and os.path.isdir(p) and p[-1] != os.sep:
        return p + os.sep
    else:
        return p

class MyShell(cmd.Cmd):
    prompt = "> "

    def do_quit(self, line):
        return True

    def do_load(self, line):
        print("load " + line)

    def complete_load(self, text, line, begidx, endidx):
        before_arg = line.rfind(" ", 0, begidx)
        if before_arg == -1:
            return # arg not found

        fixed = line[before_arg+1:begidx]  # fixed portion of the arg
        arg = line[before_arg+1:endidx]
        pattern = arg + '*'

        completions = []
        for path in glob.glob(pattern):
            path = _append_slash_if_dir(path)
            completions.append(path.replace(fixed, "", 1))
        return completions

MyShell().cmdloop()
