# huntsman

A small self-hosted HTTP service that acts as a multi-provider search router.

It exposes a single OpenSearch description that you can register in your
browser's address bar. When you type a query, a short prefix decides which
upstream search engine handles it.

## Why

Browsers let you add at most one default search engine. If you regularly
search Urban Dictionary, GitHub, and Steam, you end up adding three
engines and learning three keywords per browser. This service collapses
that into a single `<link rel="search">` and a unified prefix grammar
that works in any browser, on any device.

## Providers

| Prefix  | Provider          | Upstream                              |
| ------- | ----------------- | ------------------------------------- |
| `ud`    | Urban Dictionary  | `urbandictionary.com/define.php`      |
| `gh`    | GitHub            | `github.com/search`                   |
| `steam` | Steam Store       | `store.steampowered.com/search`       |

Both `ud foo bar` and `ud:foo bar` work. With no recognized prefix the
query falls through to the configured default provider.

## Endpoints

| Method | Path                            | Purpose                                       |
| ------ | ------------------------------- | --------------------------------------------- |
| GET    | `/`                             | Landing page advertising the OSD via `<link>` |
| GET    | `/search?q=...`                 | 302 redirect to the chosen provider           |
| GET    | `/providers`                    | JSON list of registered providers             |
| GET    | `/opensearch.xml`               | Unified OSD pointing at `/search`             |
| GET    | `/opensearch/{provider}.xml`    | Per-provider OSD pointing directly upstream   |
| GET    | `/healthz`, `/readyz`           | Liveness & readiness probes                   |

## Quick start

```sh
cp config.example.yaml config.yaml
# edit server.public_url to match your deployment
just dev
# then open http://localhost:8080/ in a browser and add the search engine
```

## Configuration

Config is YAML. Every field can be overridden by an environment variable
prefixed `APP_` with `.` replaced by `_`, e.g. `APP_SERVER_PORT=9000`.

```yaml
server:
  host: "0.0.0.0"
  port: 8080
  public_url: "https://search.example.com"  # used in OSD XML
search:
  default_provider: gh                       # ud | gh | steam
log:
  level: info
  format: human                              # human | json
```

## Build / run

```sh
just build           # produces ./huntsman
just test            # unit tests
just lint            # golangci-lint
just docker-build    # container image
just docker-run      # docker compose up -d --build
```
