Copilot CLI for Powershell

This script enables calling the GitHub Copilot CLI installed in WSL from PowerShell to provide AI-generated command suggestions for PowerShell. It is modified based on @MattJeanes' script.

Bridge script

The following bash script is used to activate nvm and call github-copilot-cli:

#!/bin/bash
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

github-copilot-cli $@

You need to add execution permission to this script (chmod +x copilot-cli-bridge.sh).

PowerShell script

Note: You need to modify the paths in the script to yours, including:

• $WSLPATH = "/mnt/c/Users/10643/AppData/Local/Temp/$($TMPFILE.Name)", change the dir to your $Env:TMP's WSL path (appears three times)
• /home/cmj/projects/scripts/copilot-cli-bridge.sh, change to your bridge script's WSL path (appears three times)

Save it as copilot.ps1 and run . copilot.ps1 to "source" these functions and alias.
