Coltrane is a Python package that allows users to render markdown files as HTML with automatic URL routing based on the filesystem. It also provides features such as using JSON files as data sources in HTML templates or markdown, automatic generation of sitemap.xml and rss.xml files, serving non-markdown files like robots.txt, and a local development server with live re-rendering of markdown and data. Coltrane follows deployment best practices with whitenoise and gunicorn already configured and can be integrated into a regular Django project as a standard third-party Django app.
Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It follows the model-view-controller (MVC) architectural pattern, providing an extensive set of built-in tools and conventions to streamline the creation of robust and scalable web applications.
