djhtml
Django/Jinja template indenter
Decision gist · record as of 2026-08-14
Yes. DjHTML is actively maintained, has no runtime dependencies, installs easily, and solves a specific problem well—indenting Django/Jinja templates without reformatting content. The GPLv3+ license is a consideration for proprietary projects, but the tool is ideal for open-source Django/Jinja workflows, especially when integrated with pre-commit. No known security vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Windows users should set the environment variable PYTHONUTF8 to 1 to ensure proper UTF-8 handling.
- Installation is straightforward with no runtime dependencies.
- The package is actively maintained with recent releases and a stable repository.

What it is and what it does
DjHTML is a pure-Python indentation tool designed specifically for Django and Jinja templates that mix HTML, CSS, and JavaScript. Unlike general formatters, it operates as an indenter—it adjusts only leading whitespace on each line without inserting newlines, removing content, or restructuring code. This makes it suitable for fixing indentation in already well-structured templates while leaving the template logic and content untouched.
The tool works as a command-line utility and integrates cleanly with pre-commit hooks for automated indentation on every commit. It supports three modes (DjHTML, DjCSS, and DjJS) that activate automatically when encountering style or script tags, and allows fine-grained control via command-line options like custom tab width and extra block tag definitions. It also respects fmt:off/fmt:on markers and ignores content inside comments and special template tags.
Use it for
- Automatically indent all Django templates in a project before each commit using pre-commit hooks.
- Fix indentation inconsistencies in Jinja templates across a codebase without altering template logic.
- Maintain consistent whitespace in mixed HTML/CSS/JavaScript template files during development.
- Dry-run indentation checks on templates using the --check flag to verify formatting without modifying files.
- Define custom block tags for non-standard template syntax and apply consistent indentation rules.
