How to remake this python3 dircache/cmd python3 - python-3.x

Question

i am wondering how to go about making this short test in python3, cmd is supported in python3 but dircache is not... currently only works on python2 but looking to change it to work in python3, thanks!
#!/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()
Ive tried using this instead of dircache but had no luck
#lru_cache(32)
def cached_listdir(d):
return os.listdir(d)

Here you go check out the load function
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()
