# Matchy

Matchy matches matchees.

Matchy is a Discord bot that groups up users for fun and vibes. Matchy can be installed on your server [here](https://discord.com/oauth2/authorize?client_id=1270849346987884696&permissions=0&integration_type=0&scope=bot).

Note: Matchy currently only allows owner-authorised users to trigger posts in channels.

## Commands
Matchy supports a bunch of user, `matcher` and bot owner commands. `/` commands are available in any channel the bot has access to, and `$` commands are only available in DMs.

| Command   | Permissions | Description                                            |
|-----------|-------------|--------------------------------------------------------|
| /join     | user        | Joins the matchee list                                 |
| /leave    | user        | Leaves the matchee list                                |
| /pause    | user        | Pauses the user for `days: int` days                   |
| /list     | user        | Lists the current matchees and scheduled matches       |
| /match    | user*       | Shares a preview of the matchee groups of size `group_min: int` with the user. *Offers a button to post the match to `matcher` users                 |
| /schedule | `matcher`   | Schedules a match every week with `group_min: int` users on `weekday: int` and at `hour: int`, on a weekly `cadence: int`.<br>Can pass `cancel: True` to stop the schedule |
| /cancel   | `matcher`   | Cancels any scheduled matches in this channel          |
| $sync     | bot owner   | Syncs bot command data with the discord servers        |
| $close    | bot owner   | Closes the bot connection so the bot quits safely      |
| $grant    | bot owner   | Grants matcher to a given user (ID)                    |

## Development
Development has been on on Linux so far, but running on Mac or Windows _should_ work fine. Please report any issues found.

### Dependencies
* `python3` - Obviously, ideally 3.11
* `venv` - Used for the python virtual env, specs in `requirements.txt`
* `docker` - Optional, for deployment

### Getting Started
```bash
git clone https://forge.mdiluz.io/mdiluz/matchy.git
cd matchy
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
git checkout -b [feature-branch-name]
```
VSCode can be configured to use this new `.venv` and is the recommended way to develop.

### Tests
Python tests are written to use `pytest` and cover most internal functionality. Tests can be run in the same way as in the Github Actions with [`test.py`](`tests/test.py`), which lints all python code and runs any tests with `pytest`. A helper script [`test-cov.py`](tests/test-cov.py) is available to generate a html view on current code coverage.

## Hosting

### State
State is stored locally in a `.matchy/state.json` file. This will be created by the bot. This stores historical information on users, maching schedules, user auth scopes and more. See [`state.py`](matchy/files/state.py) for schema information if you need to inspect it.

### Secrets
The `TOKEN` envar is required run the bot. It's recommended this is placed in a local `.env` file. To generate bot token for development see [this discord.py guide](https://discordpy.readthedocs.io/en/stable/discord.html).

### Docker
Docker and Compose configs are provided, with the latest release tagged as  `forge.mdiluz.io/mdiluz/matchy:latest`. A location for persistent data is stil required so some persistent volume will need to be mapped into the container as `/usr/share/app/.matchy`.

An example for how to do this may look like this:
```bash
docker run -v --env-file=.env ./.matchy:/usr/src/app/.matchy forge.mdiluz.io/mdiluz/matchy:latest
```

### Docker compose
Matchy can easily be hosted with `docker compose` using a file like so:
```yaml
services:
  matchy:
    image: forge.mdiluz.io/mdiluz/matchy:${MATCHY_TAG:-latest}
    env_file: ".env"
    volumes:
      - ${MATCHY_DATA:-./.matchy}:/usr/src/app/.matchy
```
