It is recommended to use this configuration in .gitconfig to ensure consistent whitespace rules, improve code readability, prevent unnecessary diffs, and maintain proper file formatting with a final newline.

[core]
    whitespace=fix,-indent-with-non-tab,trailing-space,cr-at-eol

• fix: Automatically fixes whitespace issues in patches (e.g., removes/trims trailing spaces, adds a carriage return at the end of a file if it's missing, etc.).
• -indent-with-non-tab: Prevents warnings about lines that are indented with spaces instead of tabs (essentially ignores this issue).
• trailing-space: Flags or fixes trailing spaces at the end of lines.
• cr-at-eol: Ensures that files end with a carriage return (newline) at the end of the last line.

You can apply this configuration directly from the command line by running:

git config --global --add core.whitespace fix,-indent-with-non-tab,trailing-space,cr-at-eol
