A proof of concept WordPress theme written in Elm.
To view this theme in action, go to: ulmus.mystagingwebsite.com
In order to compile the Elm source code, you need the elm package from npm. The easiest way to install npm is to install Node. You can follow instructions on how to do that here.
Once you have npm, install the elm package with:
npm install elm -g
Once you've done that, clone this repo to your system. From within this directory, you run:
elm make src/Ulmus.elm --output ulmus.js
Once that's done, this will work like a normal theme. You just need to drag the whole directory into the wp-content/themes directory of a WordPress site, and activate the theme via wp-admin.
