#!/bin/bash

# This script automates the creation of a GitHub pull request with information extracted from the current git branch name.
# It expects the branch name to contain a JIRA issue ID followed by a descriptive title.
# The script will:
# 1. Extract the JIRA issue ID from the branch name.
# 2. Format the title from the branch name.
# 3. Prompt the user to classify the issue as a bug or feature.
# 4. Prompt the user to select the target branch for the pull request.
# 5. Create the pull request using the GitHub CLI (`gh`).

# Extract the current branch name
branch_name=$(git rev-parse --abbrev-ref HEAD)

# Extract the JIRA issue ID in lowercase
jira_id_lowercase=$(echo "$branch_name" | grep -o -E '[a-zA-Z]+-[0-9]+' | head -n1)

# Convert the JIRA issue ID to uppercase
jira_id_uppercase=$(echo "$jira_id_lowercase" | tr '[:lower:]' '[:upper:]')

# Format the title by removing the JIRA issue ID and replacing hyphens with spaces
title=$(echo "$branch_name" | sed -E "s/$jira_id_lowercase-([^-]+.*)/\1/g" | sed 's/-/ /g')
title="${title#* }" # Remove the first word (feature/hotfix/etc)

# Check if the JIRA issue ID was extracted successfully
