Github copilot CLI - direct command execution

sh

# used to make github copilot cli directly suggest you the command for fast execution

# usage "ghc please tell me how to get the status of a git repo"
# output
# Recommended command: git status
# Do you want to execute this command? [Y/n]:
# Executing: git status
# On branch main
# ...

# you may wanna adjust the timeout_value in line 20 to speed things up or slow down the process in case github copilot is to slow suggesting a command
# When this value is choosen too low, github copilots suggestion may not be ready, too large, you unnecessarily wait for your result
# also you may wanna add this to your ~/.bashrc config
# tested on WSL Ubuntu

function ghc() {
    commands=$@

    tmpfile=$(mktemp)
    timeout_value=4s

    # Start the screen session and run the gh copilot suggest command
    screen -dmS ghcopilot bash -c "timeout $timeout_value script -q -c 'gh copilot suggest -t shell --shell-out $commands' $tmpfile"

    # Wait for the screen session to finish
    while screen -list | grep -q "ghcopilot"; do
        sleep 1  # Check every second if the session is still running
    done

    # Now read the output from the temporary file
    suggestion_output=$(cat "$tmpfile")

    # Clean up the temporary file
    rm "$tmpfile"

    # Strip ANSI escape sequences from the output
    clean_output=$(echo "$suggestion_output" | sed -r 's/\x1B\[[0-9;]*[a-zA-Z]//g')

    # Use regex to extract the command from the clean output and trim any leading/trailing spaces/newlines
    recommended_command=$(echo "$clean_output" | sed -n '/Suggestion:/,/Select an option/p' | grep -oP '(?<=^  ).*' | tr -d '\n' | xargs)

    # Output the captured suggestion
    if [ -n "$recommended_command" ]; then
        echo "Recommended command: $recommended_command"
        
        # Prompt the user to execute the command
        read -p "Do you want to execute this command? [Y/n]: " -r
        if [[ $REPLY =~ ^[Nn]$ ]]; then
            echo "Command not executed."
        else
            # Execute the command if the user agrees (default is Yes)
            echo "Executing: $recommended_command"
            eval "$recommended_command"
        fi
    else
        echo "No recommendation was found or the command timed out."
    fi
}

3 seconds is the sweet spot for the timeout for me
