# Update PR title and description from last commit
dub (){
    # Allows adding markdown directly within
    # the commit message and have it be used as the PR body in GitHub.
    # This enables using GFM features like diagrams, tables, codeblocks, etc.
    #
    # Pre-requisites:
    # - gh cli: https://cli.github.com/
    # - Use `;` (instead of `#`) as the comment character in Git to allow
    #   Python # comments in code blocks. Just run the following
    #   command in your terminal: git config --global core.commentChar ";"

    # Get the commit title
    title=$(git log -1 --pretty=format:%s)
    
    # Get the commit body and skip the first four lines
    body=$(git log -1 --pretty=format:%B | awk 'NR>2')
    
    # Combine the title and body
    combined_body="# $title\n\n$body"
    
    # Update the PR title
    echo "$title" | xargs -I{} gh pr edit --title "{}"
    
    # Update the PR body
    echo -e "$combined_body" | gh pr edit --body-file -
}

# View branch on GitHub
