Django HTML Formatter

This tool formats Django HTML templates by applying a consistent style to HTML and Django template blocks without altering runtime behavior. It preserves template constructs such as variables and blocks while normalizing indentation, line breaks, and attribute wrapping. The formatter analyzes both HTML structure and Django syntax to ensure that {% if %}, {{ variable }}, and {# comment #} remain intact and render identically after formatting. It is intended for developers who maintain templates across teams and projects, enabling a shared style that reduces diffs and improves readability. Core value lies in delivering predictable, repeatable results, enabling easier code reviews and handoffs between back-end and front-end roles. Use cases include refactoring legacy templates, preparing templates for version-controlled collaboration, and enforcing internal style guides for Django projects. The tool handles common edge cases such as nested blocks and long attribute lists, while reporting non-fatal diagnostics for unmatched tags or malformed constructs so the original template remains recoverable. Unique differentiators include strict preservation of Django delimiters, configurable indentation levels, and an idempotent formatter that yields the same output for already formatted templates. By separating concerns between HTML layout and template logic, it helps teams maintain readability without risking template behavior.
