# Lunch Notifier

Single-file Flask app that scrapes the daily Mariposa (Kyrene school
district) lunch menu and texts it to a list of phone numbers via
email-to-SMS carrier gateways (e.g. `4805551234@vtext.com` for Verizon).
Runs as one Docker container on the user's Unraid home server.

## Architecture

- **`app.py`** — everything: Flask web UI/API, APScheduler-style job
  scheduling (`schedule` library), and the email-to-SMS send logic
  (`smtplib` via Gmail, app password auth). The HTML/CSS/JS frontend is
  embedded as a Python string constant (`HTML`) rather than a separate
  template file — no build step, no template engine.
- **`scraper.py`** — fetches and parses the school's published lunch menu.
- **`scheduler.py`** — day-of-week/time scheduling helpers used by `app.py`.
- Settings (phone numbers, send time, days, vacation date ranges) persist
  to `/data/settings.json`, not environment variables — env vars
  (`PHONE_NUMBER`, `RUN_TIME`, `RUN_DAYS`) are defaults used only the very
  first time, before a settings file exists.
- Vacation ranges suppress sends without disabling the schedule — checked
  fresh on every run via `is_on_vacation()`.

## Local development

```bash
pip install -r requirements.txt
python3 app.py
```

Needs `GMAIL_USER` and `GMAIL_APP_PASSWORD` env vars to actually send
(a Gmail **app password**, not the account password — required since Gmail
disallows plain SMTP auth with the real password). Visit
`http://localhost:2323`.

## Deployment

**Target:** Unraid server, container path `/mnt/user/appdata/lunch-notifier`,
built from `Dockerfile`/`docker-compose.yml` in this repo. Container name
`Lunch-Notifier`, port `2323`. No reverse proxy — accessed directly via
`http://<server-ip>:2323` on the LAN.

**Deploy mechanism: Forgejo push-to-deploy**, same pattern as the other
three projects on this box (`card-grader`, `n64-tracker`, `arr-summary`) —
see `card-grader`'s `CLAUDE.md` for the full pipeline mechanics (runner
config, HTTPS-not-SSH git auth, known tradeoffs). In short: push to `main`
on the `forgejo` remote (`https://git.hippofam.com/ninja_hippo/lunch-notifier.git`)
triggers `.forgejo/workflows/deploy.yml`, which syncs into
`/mnt/user/appdata/lunch-notifier` (excluding `.git`, `.env`, `data/`) and
runs `docker compose up -d --build`.

**Persistent state, never touched by deploys:** `data/settings.json` (the
volume-mounted `/data` inside the container) holds phone numbers, schedule,
and vacation ranges — this is live user data, not deploy-managed. `.env`
holds `GMAIL_USER`/`GMAIL_APP_PASSWORD`/`PHONE_NUMBER` etc. and is
server-only, gitignored, never committed.

**Migration note (2026-08-25):** this container originally used a Docker
**named volume** (`lunch-notifier_lunch-settings`) instead of a bind mount.
That meant Unraid's Appdata Backup plugin — which only knows about
`/mnt/user/appdata` and `/mnt/cache/appdata` as backup sources — silently
skipped it entirely; the settings data was never included in any backup.
Migrated to a bind mount (`./data:/data`) with the existing settings copied
over first and verified intact before the old named volume was deleted.
