Bug: ModuleNotFoundError for wcwidth when running oneshot.py in Termux

[libra1024]

Describe the bug

When attempting to run oneshot.py on Termux, the script fails to execute due to a missing Python library: wcwidth (ModuleNotFoundError).

Attempting to fix this by using apt install wcwidth does not work because apt searches for native Termux system packages, not Python modules.

To Reproduce

Steps to reproduce the behavior in Termux:

1. Follow the manual installation steps for Termux in the README.
2. Execute the script: sudo python OneShot/oneshot.py -i wlan0 -K
3. See the ModuleNotFoundError for wcwidth.

Root Cause

The Python dependency wcwidth is not installed by default in the Termux environment or via the currently documented pkg install commands.

Proposed Solution

The module must be installed via the Python package manager (pip).

1. Install the dependency with pip:

   pip install wcwidth

2. Root environment fallback:
   Since the script is executed as a superuser (sudo), the root Python environment might have separate paths. If the error persists after step 1, install it directly in the root environment:

   sudo pip install wcwidth

3. Run the script again:

   sudo python OneShot/oneshot.py -i wlan0 -K

Suggested Action

Update the Termux section in the README.md to include instructions for installing wcwidth via pip.

Thanks a lot for the detailed report and the clear root-cause analysis @libra1024 — spot on. wcwidth is a Python module, not a Termux package, so pkg/apt install wcwidth won't find it; it has to come from pip.

Fixed on master (also on the consolidate-forks branch):

• oneshot.py now imports wcwidth with a graceful fallback to len(), so the script no longer crashes if the module is missing (column alignment may be slightly off for wide/CJK characters, but it runs).
• installer.sh and the README Termux steps now run pip install wcwidth, so the proper alignment is available too.

Could you pull the latest master and confirm it works on your Termux setup? If it's good on your end I'll close this. Thanks again for the writeup!
