# Tefter

Self-hosted, single-user notes with the classic **Notational Velocity** interaction model:
one omnibar that searches *and* creates, instant filtering on every keystroke, no save
buttons, no dialogs, everything on the keyboard. Markdown editing with preview,
offline-first sync across Linux/macOS/Windows/Android/web.

One Go binary (`tefterd`) + one SQLite file. The web app (PWA) is embedded in the binary;
the desktop app is the same frontend in a Wails shell.

## Quick start (server)

```sh
make server            # builds frontend + tefterd into build/tefterd
./build/tefterd init   # creates tefter.db, prints your auth token — save it
./build/tefterd        # serves on :8420
```

Open `http://localhost:8420`, click `⋯` → set server URL + token → Save.

### Keyboard model

| Key | Action |
|---|---|
| type in omnibar | filter notes instantly (title > prefix > contains > body; diacritic-insensitive) |
| `Enter` | open selected note / create note titled with the query |
| `↑` `↓` | move list selection (editor live-previews) |
| `Esc` | editor → omnibar; omnibar → clear |
| `Ctrl/Cmd+L` | focus omnibar, select text |
| `Ctrl/Cmd+Delete` | delete note (undo toast, no confirm) |
| `Ctrl/Cmd+Shift+P` | toggle markdown preview (`[[wiki-links]]` open/create notes) |
| `Ctrl/Cmd+K` | cycle tag filter |
| `Ctrl/Cmd+J` / `+Shift` | next / previous note while editing |

## CLI

```sh
tefterd                              # serve (default), flags: --listen :8420 --db tefter.db
tefterd init                         # create db + print token
tefterd token rotate                 # new token (old one stops working)
tefterd import simplenote export.zip # idempotent Simplenote import (also in the web UI)
tefterd compact --days 90            # purge old tombstones
tefterd backup /backups/tefter.db    # consistent snapshot (VACUUM INTO)
tefterd version
```

Environment: `TEFTER_DB`, `TEFTER_LISTEN` override the flag defaults. No config file.

## Deployment

`tefterd` listens on plain HTTP; put TLS in front of it.

**systemd** — `/etc/systemd/system/tefterd.service`:

```ini
[Unit]
Description=Tefter notes server
After=network.target

[Service]
User=tefter
ExecStart=/usr/local/bin/tefterd --db /var/lib/tefter/tefter.db --listen 127.0.0.1:8420
Restart=on-failure

[Install]
WantedBy=multi-user.target
```

**Caddy** (two lines):

```
notes.example.com {
    reverse_proxy 127.0.0.1:8420
}
```

**Backup** = one file:

```sh
tefterd backup /backups/tefter-$(date +%F).db --db /var/lib/tefter/tefter.db
```

## Clients

- **Web / Android:** open the server URL, install as PWA (Chrome: “Add to home screen”).
  Fully offline-capable; edits sync on reconnect.
- **Desktop:** `tefter-desktop` (Wails). Single instance, closes to tray,
  global shortcut `Ctrl+Shift+Space` (change with `--hotkey` / `TEFTER_HOTKEY`;
  `--quit-on-close` disables the tray behavior). Works with no server at all —
  configure sync later under `⋯`.

## Sync model

Pull-then-push, last-write-wins with **conflict copies** (Simplenote-style). Concurrent
edits of the same note never silently overwrite: the loser comes back as a new note
tagged `conflict` with “(conflicted copy …)” in its title. Delete-vs-edit: the edit wins.
Every client keeps a full offline copy in IndexedDB; a crash mid-sync loses nothing.

## Development

```sh
make dev        # vite dev server (proxies /api to :8420)
make test       # go vet + go test (uses notes.zip for a real-import test when present)
make server     # build/tefterd for this machine
make server-all # linux/amd64, linux/arm64, darwin/arm64, windows/amd64
make desktop    # Wails build (needs wails CLI + GTK/WebKit dev packages on Linux)
```

Repo layout: `frontend/` (Svelte + TS, all app logic incl. offline store + sync engine),
`server/` (Go, stdlib HTTP + modernc.org/sqlite, no CGO), `desktop/` (Wails shell).
