# Gitea Mail Templates

A curated collection of professionally designed, audience-driven email templates for self-hosted [Gitea](https://about.gitea.com) instances.

[![Gitea](https://img.shields.io/badge/Gitea-1.25+%20%7C%201.27.0%20tested-blue)](COMPATIBILITY.md) <!-- TRACKER:BADGE -->

> **110 template files — 10 visual styles, 11 email types each**

---

## Philosophy

Most self-hosted Gitea instances use the default plain email templates. This project provides **ready-to-deploy, visually polished alternatives** — each designed for a specific community or audience, so you can pick the one that feels right for your users.

Every template is a drop-in replacement. All Go template variables, translation keys, and Gitea data contexts are fully compatible. **No patches, no plugins, no forks required.**

## Installation

### Quick Start

Choose a style, then copy the `mail/` directory into your Gitea custom templates path:

```bash
# Locate your Gitea custom directory
#   (set by GITEA_CUSTOM; defaults shown below)

# Copy templates (example: Horizon style)
cp -r themes/horizon/mail/* /var/lib/gitea/custom/templates/mail/

# Restart Gitea
systemctl restart gitea
```

### Custom Directory Location

| Platform | Default Path |
|---|---|
| Linux (binary) | `/var/lib/gitea/custom` |
| Linux (Docker) | `/data/gitea` |
| Windows | `C:\gitea\custom` |

### Switching Styles

Overwrite the files with a different style. All templates share the exact same variable structure — no configuration changes needed.

```bash
cp -r themes/terminal/mail/* /var/lib/gitea/custom/templates/mail/
systemctl restart gitea
```

### Confirming It Works

The admin test email does not use custom mail templates. To verify your templates
are active, trigger a real email notification. The quickest way is the password
reset flow: log out, click **"Forgot password"** on the login page, and check the
reset email — it will render with your custom styles.

## Preview

Two modes are available — a zero-dependency static preview for quick checks, and a live-reload dev server for design work.

### Static Preview

Generate the preview data once (Go only), then open in a browser:

```bash
cd tools && go run . preview all
open preview/index.html        # no server needed
```

### Dev Server (Live Reload)

Start a pure Go development server that watches for `.tmpl` changes, auto-rebuilds, and pushes live updates to the browser via SSE:

```bash
cd tools && go run . dev
open http://localhost:3456
```

| Capability | Static | Dev |
|-----------|--------|-----|
| Go template rendering | ✅ | ✅ |
| Theme/template switching | ✅ | ✅ |
| Live reload on save | — | ✅ |

### Features

- Theme switcher — browse all 10 visual styles
- Template switcher — all 11 email types
- View mode — Modern (rendered preview), Source (raw HTML)
- Viewport toggle — Desktop 1386×780 / Mobile 390×780
- Parameter panel — mock data per email type
- Keyboard shortcuts — `←→` tab between Theme/Template/View, `↑↓` select within, `d`/`m` viewport

## Compatibility

- **Gitea 1.25+** — matches the refactored mail template directory structure (v1.25)
- **Latest tested:** Gitea 1.27.0 <!-- TRACKER:LATEST-TESTED -->
- 100% variable-compatible with official Gitea templates — see [COMPATIBILITY.md](COMPATIBILITY.md) for the full matrix
- Uses only built-in Gitea template functions and official translation keys
- No custom template functions or locale patches required

---

## Design Principles

1. **Responsive** — Max-width 600px cards; works in all email clients
2. **Accessible** — 4.5:1 contrast ratios; semantic HTML
3. **Graceful degradation** — Fallback link visible when buttons fail to render
4. **Logo support** — References `{{AppUrl}}assets/img/favicon.png` by default
5. **i18n-ready** — All user-facing strings use Gitea's `{{.locale.Tr}}` system
