EPL — Website

The official marketing site for EPL, the English-like programming language. What makes this repo unusual: the website is itself written in EPL. There is no HTML, CSS framework, or JS build chain in the source — src/main.epl is a single EPL program that emits the entire page (layout, design system, animations, and an embedded live playground) through EPL's native web DSL.

A small Python driver (build.py) renders that program to static HTML so it can be hosted anywhere.

Highlights

• Written in EPL — the full landing page, legal pages, and an interactive playground are authored in src/main.epl.
• Embedded live playground — a native in-page editor + Run button that executes real EPL against the live playground backend.
• Zero-config static output — absolute server routes are rewritten to relative .html links, so the built site works when opened locally and on any static host (GitHub Pages, Netlify, Cloudflare Pages, Azure Static Web Apps).
• Continuous deploy — every push to main rebuilds the site and publishes it to GitHub Pages via GitHub Actions.

Build locally

Requires Python 3.10+.

pip install -r requirements.txt
python build.py

This writes index.html, terms.html, privacy.html, and refund.html to dist/. Open dist/index.html directly in a browser, or serve the folder:

python -m http.server --directory dist 8123
# then open http://127.0.0.1:8123/

To preview with hot-reload straight from source (no static export):

python -m epl serve src/main.epl --dev

Deployment

Pushes to main trigger .github/workflows/deploy.yml, which installs the EPL compiler, runs python build.py, and deploys dist/ to GitHub Pages. To enable it, set Settings → Pages → Source = GitHub Actions once.

The site can also be deployed to any static host by uploading the contents of dist/.
