With this template, you can preview & render .tex and .latex files in iA Writer. It was inspired by iA’s Fountain Template, which also uses JavaScript to add support for a markup language to Writer.
The template uses latex.js for the LaTeX translation and thus comes with certain limitations. In addition, the hack-y nature of this implementation means workarounds are needed for adding images and other external content.
This template was built for personal use, but feel free to use, clone and modify it!
