I’m stuck on Stage #ue6.
Here are my logs:
```auto
[tester::#ZV2] ✓ Prompt line matches "$ wc grape-"
[tester::#ZV2] Pressed "" (expecting autocomplete to "wc grape-90.txt" followed by a space)
[your-program] $ wc grape-grape-90.txt
[tester::#ZV2] ^ Line does not match expected value.
[tester::#ZV2] Expected: "$ wc grape-90.txt "
[tester::#ZV2] Received: "$ wc grape-grape-90.txt "
```
Locally when I run it, It is working correctly.
Python Completer code:
```auto
builtin=["exit", "echo", "type", "pwd","cd"]
autocomplete_list=builtin.copy()
for path in os.environ.get("PATH", "").split(os.pathsep):
if os.path.exists(path):
autocomplete_list.extend(os.listdir(path))
def completer(text,state):
buffer = readline.get_line_buffer()
last_word = buffer.split()[-1] if buffer else ""
prev_path = Path(last_word)
if not prev_path.is_dir():
prev_path = Path()
if not text:
options=([cmd for cmd in os.listdir(prev_path)])
else:
if '/' not in text and '\\' not in text:
options = [cmd for cmd in autocomplete_list if cmd.startswith(text)]
options.extend([cmd for cmd in os.listdir() if cmd.startswith(text)])
else:
path = prev_path/Path(text)
prefix = ".\\" if not path.is_absolute else ""
if path.is_dir():
options = [prefix+str(path/cmd) for cmd in os.listdir(path)]
else:
path_dir = path.parent.absolute()
path_text = path.name
options = [cmd for cmd in os.listdir(path_dir) if cmd.startswith(path_text)]
if state < len(options):
option = Path(options[state])
if option.is_dir():
return str(option)+"/"
return options[state]+" "
return None
```
What am I here?

Hey @Gautam1608, looks like you’ve got past this stage. Do you happen to remember what was wrong? Would love to see if we can improve the tester / instructions.

I… dont know haha.
So 1st thing I did is to stop using powershell(default terminal in vscode).
I change it to git bash.
That meant I didnt need to worry about windows and posix, so I changed the completion to posix output:
```auto
def completer(text,state):
if not text:
options=([cmd for cmd in os.listdir()])
else:
if '/' not in text and '\\' not in text:
options = [cmd for cmd in autocomplete_list if cmd.startswith(text)]
options.extend([cmd for cmd in os.listdir() if cmd.startswith(text)])
else:
path = Path(text)
prefix = "./" if not path.is_absolute() else ""
if path.is_dir():
options = [prefix+(path/cmd).as_posix() for cmd in os.listdir(path)]
else:
path_dir = path.parent.absolute() if path.parent.absolute().is_dir() else Path()
path_text = path.name
options = [(path.parent/cmd).as_posix() for cmd in os.listdir(path_dir) if cmd.startswith(path_text)]
if state < len(options):
option = Path(options[state])
if option.is_dir():
return option.as_posix()+"/"
return options[state]+" "
return None
```
I am not a pro, and I have written so much code that I am feeling a little lost myself.
The changes I made was to remove the readline.get\_line\_buffer() as in bash text is the full “word” unlike powershell, which I still dont know what text it was giving me.
I believe something here solved the problem.
Although I am facing a similar problem yet again:
```auto
[tester::#LC6] Running tests for Stage #LC6 (Filename Completion - Directory completion)
[tester::#LC6] [working_dir] - rat/
[tester::#LC6] [working_dir] - pig/ (empty)
[tester::#LC6] Running ./your_program.sh
[tester::#LC6] ✓ Received prompt ($ )
[tester::#LC6] Typed "ls" followed by a
[tester::#LC6] ✓ Prompt line matches "$ ls "
[tester::#LC6] Pressed "" (expecting autocomplete to "ls rat/")
[tester::#LC6] ✓ Prompt line matches "$ ls rat/"
[tester::#LC6] Pressed "" (expecting autocomplete to "ls rat/pig/")
[your-program] $ ls rat/rat/
[tester::#LC6] ^ Line does not match expected value.
[tester::#LC6] Expected: "$ ls rat/pig/"
[tester::#LC6] Received: "$ ls rat/rat/"
[tester::#LC6] Test failed
```
But the code locally is working fine:
> $ ls
> app codecrafters.yml grape-90.txt pig pyproject.toml README.md uv.lock your\_program.sh
> $ cd pig
> $ ls
> owl
> $ cd ..
> $ cd pig/owl/
> $
I did the exercise step for step. I am not able to replicate the failure locally.
FYI I typed: cd pig/ and it gave me cd pig/owl/
This time it should not be posix and windows issue, atleast thats what i believe.
Edit: I think this is important and I forgot to mention, readline doesnt work for windows.
So I am using the below import to resolve this. Took me good few tries to come up with this idea and I dont even know if it works or not.
```auto
try:
import readline
except ImportError:
try:
from pyreadline3 import Readline
readline = Readline()
def input(txt):
readline.readline(txt)
except ImportError:
readline = None
```

@Gautam1608 To make sure any earlier stages are not broken, you can use [our CLI](https://docs.codecrafters.io/cli/installation) to test against previous stages by running:
```auto
codecrafters test --previous
```
This is a handy way to catch regressions.
