When MATRIX_USE_THREADS=true, deals are posted into dedicated threads instead of the room timeline: - 🎮 Game Deals — CheapShark + ITAD type=game - 🧩 DLC Deals — ITAD type=dlc - 🆓 Epic Free Games — current and upcoming Epic free games - 📦 Non-Game Deals — ITAD non-game content (software, courses, etc.) Thread roots are created on first use and persisted in the database. When threads are disabled (default), behaviour is unchanged. Key changes: - New threads.py module with ThreadCategory enum and routing logic - ITADDeal now carries deal_type; type filter moved from fetcher to bot - MatrixDealsClient gains send_deal_in_thread() and create_thread_root() - Database gets thread_roots table for storing root event IDs - Bot routes each deal to the appropriate thread via _send_to_thread_or_room() https://claude.ai/code/session_01EfPjktyrF24DBNHWsY1KBP

# Pastel
|
|
|
|
A Matrix bot that posts gaming deals and free game alerts to a specified Matrix room.
|
|
|
|
Deals are sourced from PC/digital storefronts only (Steam, GOG, Humble Store, GreenManGaming, Epic Games Store) — universally accessible regardless of region.
|
|
|
|
## Data Sources
|
|
|
|
- **CheapShark** — polled every 2 hours for top deals across Steam, GOG, Humble Store, and GreenManGaming
|
|
- **IsThereAnyDeal** — polled every 2 hours for deals across all tracked stores, with built-in historical low detection (requires API key)
|
|
- **Epic Games Store** — polled daily for free game promotions
|
|
|
|
CheapShark and IsThereAnyDeal can be used individually or together — configure via the `DEAL_SOURCES` variable. When used as a deal source, IsThereAnyDeal provides historical low flags directly. When only CheapShark is active, IsThereAnyDeal can still optionally enrich deals with historical low info via the `ITAD_API_KEY`.
|
|
|
|
## Quick Start
|
|
|
|
1. Copy `.env.example` to `.env` and fill in your Matrix credentials and room ID
|
|
2. Run with Docker:
|
|
|
|
```bash
|
|
docker build -t pastel .
|
|
docker run --env-file .env -v pastel-data:/data pastel
|
|
```
|
|
|
|
Or run directly with Python 3.12+:
|
|
|
|
```bash
|
|
pip install -r requirements.txt
|
|
python -m gaming_deals_bot
|
|
```
|
|
|
|
## Obtaining a Matrix Bot Access Token
|
|
|
|
1. **Create a bot account** on your homeserver (e.g. via Element: register a new account like `@dealsbot:example.com`).
|
|
|
|
2. **Log in and get the access token** using `curl`:
|
|
|
|
```bash
|
|
curl -XPOST "https://matrix.example.com/_matrix/client/v3/login" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{
|
|
"type": "m.login.password",
|
|
"identifier": { "type": "m.id.user", "user": "dealsbot" },
|
|
"password": "YOUR_PASSWORD"
|
|
}'
|
|
```
|
|
|
|
The response will contain an `access_token` field — copy that value into your `.env` as `MATRIX_BOT_ACCESS_TOKEN`.
|
|
|
|
3. **Invite the bot** to your deals room, then have the bot **accept the invite** (the bot does this automatically on startup).
|
|
|
|
> **Tip:** After extracting the token you can change the bot account's password without invalidating the token. Store the token securely — anyone with it can act as the bot.
|
|
|
|
## Configuration
|
|
|
|
All configuration is via environment variables (see `.env.example`):
|
|
|
|
### Core
|
|
|
|
| Variable | Required | Default | Description |
|
|
|---|---|---|---|
|
|
| `MATRIX_HOMESERVER_URL` | Yes | — | Matrix homeserver URL |
|
|
| `MATRIX_BOT_USER_ID` | Yes | — | Bot's Matrix user ID |
|
|
| `MATRIX_BOT_ACCESS_TOKEN` | Yes | — | Bot's access token |
|
|
| `MATRIX_DEALS_ROOM_ID` | Yes | — | Room ID to post deals in |
|
|
| `ITAD_API_KEY` | No | — | IsThereAnyDeal API key (required when `itad` is in `DEAL_SOURCES`, optional otherwise for historical low detection) |
|
|
| `DEAL_SOURCES` | No | cheapshark | Comma-separated deal sources: `cheapshark`, `itad`, or `cheapshark,itad` |
|
|
| `ITAD_COUNTRIES` | No | US | Comma-separated ISO 3166-1 alpha-2 country codes to fetch ITAD deals from (e.g. `US,CA,GB,DE`) |
|
|
| `DEFAULT_CURRENCY` | No | USD | Primary display currency shown first in price strings |
|
|
| `EXTRA_CURRENCIES` | No | CAD,EUR,GBP | Additional currencies shown after the default (comma-separated) |
|
|
| `MATRIX_USE_THREADS` | No | false | Post deals into per-category threads (see Threads section below) |
|
|
| `SEND_INTRO_MESSAGE` | No | false | Send "The deals must flow." to the room on startup |
|
|
| `DATABASE_PATH` | No | deals.db | Path to SQLite database file |
|
|
|
|
### Filtering
|
|
|
|
Each deal source has its own filter settings. Source-specific values take priority; when not set they fall back to the shared defaults.
|
|
|
|
| Variable | Source | Default | Description |
|
|
|---|---|---|---|
|
|
| `CHEAPSHARK_MIN_DISCOUNT` | CheapShark | 50 | Minimum discount percentage |
|
|
| `CHEAPSHARK_MIN_RATING` | CheapShark | 8.0 | Minimum deal rating (0-10, 0 = unrated allowed) |
|
|
| `CHEAPSHARK_MAX_PRICE` | CheapShark | 20 | Maximum sale price (USD) |
|
|
| `ITAD_MIN_DISCOUNT` | ITAD | 50 | Minimum discount percentage |
|
|
| `ITAD_MAX_PRICE` | ITAD | 20 | Maximum sale price (USD, prices from other regions are converted) |
|
|
| `ITAD_DEALS_LIMIT` | ITAD | 200 | Number of deals to fetch per country (max 200) |
|
|
| `MIN_DISCOUNT_PERCENT` | Shared | 50 | Fallback minimum discount when source-specific value is not set |
|
|
| `MAX_PRICE` | Shared | 20 | Fallback maximum price when source-specific value is not set |
|
|
|
|
## Preflight Check
|
|
|
|
Run `--check` to validate your configuration and test connectivity to all services before starting the bot:
|
|
|
|
```bash
|
|
python -m gaming_deals_bot --check
|
|
```
|
|
|
|
This verifies:
|
|
|
|
- **Matrix** — authentication token is valid and bot has joined the target room
|
|
- **CheapShark** — API is reachable (skipped if not in `DEAL_SOURCES`)
|
|
- **Epic Games Store** — API is reachable
|
|
- **Frankfurter** — exchange rate API is reachable
|
|
- **IsThereAnyDeal** — API key is valid (required when `itad` is in `DEAL_SOURCES`, skipped otherwise if not configured)
|
|
|
|
The command exits with code 0 on success and 1 on failure, so it works in CI and Docker health-checks.
|
|
|
|
## Threads
|
|
|
|
When `MATRIX_USE_THREADS=true`, deals are posted inside per-category threads instead of directly into the room timeline. This keeps the room organized and lets users follow only the categories they care about.
|
|
|
|
| Thread | Content |
|
|
|---|---|
|
|
| 🎮 Game Deals | CheapShark deals + ITAD deals with type `game` |
|
|
| 🧩 DLC Deals | ITAD deals with type `dlc` |
|
|
| 🆓 Epic Free Games | Current and upcoming free games from the Epic Games Store |
|
|
| 📦 Non-Game Deals | ITAD deals that aren't games or DLC (software, courses, etc.) |
|
|
|
|
Thread root messages are created automatically the first time a deal in that category appears. The root event IDs are stored in the database so subsequent deals are posted into the same threads.
|
|
|
|
When threads are **disabled** (default), the bot behaves as before — all deals post directly to the room and non-game ITAD content is excluded.
|
|
|
|
## Behavior
|
|
|
|
- **First run**: fetches current deals and records them in the database without posting (avoids spamming the room with existing deals)
|
|
- **Deduplication**: deals are tracked by game ID + timestamp; duplicates are never reposted
|
|
- **Pruning**: deals older than 30 days are pruned from the database so they can be reposted if they return
|
|
- **One message per deal**: each deal is posted individually so messages are independently linkable and dismissible
|
|
- **Multi-currency pricing**: deal prices are shown in your configured currencies (default: USD, CAD, EUR, GBP) using live exchange rates from the [Frankfurter API](https://api.frankfurter.dev) (ECB data, no API key required). Set `DEFAULT_CURRENCY` to change the primary display currency and `EXTRA_CURRENCIES` for additional ones. Rates are cached and refreshed twice daily.
|
|
- **Multi-country ITAD deals**: when using IsThereAnyDeal, deals can be fetched from multiple countries simultaneously via `ITAD_COUNTRIES` (e.g. `US,CA,GB,DE`). Deals are merged and deduplicated, with the first country in the list taking priority for duplicate games.
