QaDiL - Quick and Dirty interactive LaTeX

Niels Lauritzen

A LaTeX like system using KaTeX and SageMathCell for fast production of (mathematics) html-notes with interactive elements. Use requires (installation of) python and make and knowledge of editing LaTeX with a (plain) text editor. Preview of html can be done in any browser. Publishing your notes is as easy as unzipping a file (for example in your GitHub webpage repo).
