A ChatGPT prompt generation script to summarize & review the code changes between two branches

#!/bin/bash

# This script will help you to generate a ChatGPT prompt that you can use to summarize and review the changes between two branches.
# It will prompt you for the feature branch, the branch to compare to, the ticket/story/bug description, and any additional feedback.
# It will then output the changes and the prompt to a file called summareview.txt.

# Get the current branch
current_branch=$(git rev-parse --abbrev-ref HEAD)

# Prompt for feature branch (default: current branch)
read -p "Enter the feature branch to compare (default: $current_branch): " feature_branch
feature_branch=${feature_branch:-$current_branch}

# Prompt for branch to compare to (default: develop)
read -p "Enter the branch to compare to (default: develop): " compare_branch
compare_branch=${compare_branch:-develop}

# Prompt for ticket/story/bug description
read -p "Enter the ticket/story/bug description: " ticket_description

# Prompt for additional feedback
read -p "Enter any additional feedback (optional): " additional_feedback

# Execute git log command and store the output in a variable
git_log_output=$(git log $compare_branch..$feature_branch --oneline)

# Execute git diff command and store the output in a variable
git_diff_files_output=$(git diff --name-status $compare_branch..$feature_branch -- . ':(exclude)./**/package-lock.json' ':(exclude)./**/composer.lock')

# Execute git diff command and store the output in a variable, excluding package-lock.json and composer.lock
git_diff__lines_output=$(git diff $compare_branch..$feature_branch -- . ':(exclude)./**/package-lock.json' ':(exclude)./**/composer.lock')

# Add ChatGPT prompt
