Generate a `latest.json` file for [Tauri](https://v2.tauri.app/) auto-updates, supporting multi-platform builds (Windows, macOS Intel/ARM, Linux).

This CLI scans your Tauri `bundle` directory for installers and outputs a valid `latest.json` for the [Tauri Updater](https://v2.tauri.app/plugin/updater/).

## Features

- Detects installers: `.msi`, `.exe`, `.dmg` (Intel/ARM), `.AppImage`, `.deb`, `.rpm`, `.tar.gz`
- Auto-detects platform keys from filenames
- Reads version from `package.json` or `Cargo.toml`
- Generates a single multi-platform `latest.json`
- CLI-only tool (not intended as a Rust library dependency)

## Install

```bash
cargo install tauri-latest-json
```

## CLI Usage

```bash
tauri-latest-json <download_url_base> <notes>
```

```bash
tauri-latest-json help
tauri-latest-json version
tauri-latest-json --help
tauri-latest-json --version
```

Notes can contain spaces without quotes; all remaining args are combined.

Example:

```bash
tauri-latest-json https://example.com/downloads Initial release with details
```

`latest.json` is written to the current working directory.

### Optional signature verification

Enable compile-time verification of signatures using the Tauri CLI:

```bash
cargo install tauri-cli
cargo run --features verify-signature -- <download_url_base> <notes>
```

If the paths are correct, you’ll see `latest.json generated successfully`.

## Requirements

- Valid Tauri updater configuration (see the [Tauri Updater docs](https://v2.tauri.app/plugin/updater/))
- A Tauri signing key

```bash
pnpm tauri signer generate -w ~/.tauri/myapp.key
```

## Platform Detection

| File Extension                               | Platform Key     |
| -------------------------------------------- | ---------------- |
| `.msi`, `.exe`                               | `windows-x86_64` |
| `.dmg` (Intel)                               | `darwin-x86_64`  |
| `.dmg` (ARM)                                 | `darwin-aarch64` |
| `.AppImage`, `.deb`, `.rpm`, `.tar.gz` (x64) | `linux-x86_64`   |
| `.AppImage`, `.deb`, `.rpm`, `.tar.gz` (ARM) | `linux-aarch64`  |

## Specs

Behavior specs and acceptance criteria are documented in [SPEC.md](SPEC.md).

## Testing

Run the verification suite:

```bash
make verify
```

Manual equivalent:

```bash
cargo test
cargo test --all-features
cargo check --features verify-signature
./scripts/smoke-cli.sh
./scripts/smoke-generate.sh
./scripts/smoke-generate-current-conf.sh
```
