# 📝 Configuration
Haven't set up the bot yet? Check out [Setting up the bot](setup.md) first!

## Configuration file
All bot options are saved in a configuration file in the bot's folder.
This is created during the [setup](setup.md) and is generally either `config.ini` or, if you've been using the bot for
longer, `config.json`.

The instructions on this page are for `config.ini` but can be adapted to `config.json` as well.
See [config.ini vs config.json](#configini-vs-configjson) for more details.
Note that the format of `.ini` and `.json` are different -- you can't simply rename a `.json` to `.ini` or
vice versa.

## Adding new options
To add a new option to your `config.ini`, open the file in a text editor such as notepad.
Each option is put on a new line, and follows the format `option = value`. For example, `mainGuildId = 1234`.

**You need to restart the bot for configuration changes to take effect!**

You can add comments in the config file by prefixing the line with `#`. Example:
```ini
# This is a comment
option = value
```

### Toggle options
Some options like `allowMove` are "**Toggle options**": they control whether certain features are enabled (on) or not (off).
* To enable a toggle option, set its value to `on`, `true`, or `1`
* To disable a toggle option, set its value to `off`, `false`, or `0`
* E.g. `allowMove = on` or `allowMove = off`

### "Accepts multiple values"
Some options are marked as "**Accepts multiple values**". To give these options multiple values,
write the option as `option[] = value` and repeat for every value. For example:

```ini
inboxServerPermission[] = kickMembers
inboxServerPermission[] = manageMessages
```

You can also give these options a single value in the usual way, i.e. `inboxServerPermission = kickMembers`

### Multiple lines of text
For some options, such as `greetingMessage`, you might want to add text that spans multiple lines.
To do that, use the same format as with "Accepts multiple values" above:

```ini
greetingMessage[] = Welcome to the server!
greetingMessage[] = This is the second line of the greeting.
greetingMessage[] = 
greetingMessage[] = Fourth line! With an empty line in the middle.
```

```ini
guildGreetings.94882524378968064.message = Welcome to server ID 94882524378968064!
guildGreetings.94882524378968064.attachment = greeting.png

guildGreetings.541484311354933258.message[] = Welcome to server ID 541484311354933258!

## config.ini vs config.json
Earlier versions of the bot instructed you to create a `config.json` instead of a `config.ini`.
**This is still fully supported, and will be in the future as well.**
However, there are some differences between `config.ini` and `config.json`.

### Formatting
*See [the example on the Wikipedia page for JSON](https://en.wikipedia.org/wiki/JSON#Example)
for a general overview of the JSON format.*

* In `config.json`, all text values and IDs need to be wrapped in quotes, e.g. `"mainGuildId": "94882524378968064"`
* In `config.json`, all numbers (other than IDs) are written without quotes, e.g. `"port": 3000`

### Toggle options
In `config.json`, valid values for toggle options are `true` and `false` (not quoted),
which correspond to `on` and `off` in `config.ini`.

### "Accepts multiple values"
Multiple values are specified in `config.json` using arrays:
```json
{
  "inboxPermission": [
    "kickMembers",
    "manageMessages"
  ]
}
```

### Multiple lines of text
Since `config.json` is parsed using [JSON5](https://json5.org/), multiple lines of text are supported
by escaping the newline with a backslash (`\ `):
```json5
{
  "greetingMessage": "Welcome to the server!\
This is the second line of the greeting."
}
```

## Other formats
Loading config values programmatically is also supported.
Create a `config.js` in the bot's folder and export the config object with `module.exports`.
All other configuration files take precedence, so make sure you don't have both.

## Environment variables
Config options can be passed via environment variables.

To get the name of the corresponding environment variable for an option, convert the option to SNAKE_CASE with periods
being replaced by two underscores and add `MM_` as a prefix. If adding multiple values for the same option, separate the
values with two pipe characters: `||`.

Examples:
* `mainGuildId` -> `MM_MAIN_GUILD_ID`
* `commandAliases.mv` -> `MM_COMMAND_ALIASES__MV`
* From:  
  ```ini
  inboxServerPermission[] = kickMembers
  inboxServerPermission[] = manageMessages
  ```  
  To:  
  `MM_INBOX_SERVER_PERMISSION=kickMembers||manageMessages`

The `port` option also accepts the environment variable `PORT` without a prefix, but `MM_PORT` takes precedence.
