# Luzifer / twitch-bot

Twitch-Bot is intended as an alternative to having a bot managed by Streamlabs or Streamelements and therefore having more control over it, the availability and how it works.

At the moment it is a work-in-progress and does not yet implment all features it shall in the future.

## Configuration

Please see the [Wiki](https://github.com/Luzifer/twitch-bot/wiki) for documentation of the configuration file.

```console
# twitch-bot --help
Usage of twitch-bot:
      --base-url string                  External URL of the config-editor interface (set to enable EventSub support)
      --command-timeout duration         Timeout for command execution (default 30s)
  -c, --config string                    Location of configuration file (default "./config.yaml")
      --log-level string                 Log level (debug, info, warn, error, fatal) (default "info")
      --plugin-dir string                Where to find and load plugins (default "/usr/lib/twitch-bot")
      --rate-limit duration              How often to send a message (default: 20/30s=1500ms, if your bot is mod everywhere: 100/30s=300ms, different for known/verified bots) (default 1.5s)
      --storage-database string          Database file to store data in (default "./storage.db")
      --storage-encryption-pass string   Passphrase to encrypt secrets inside storage (defaults to twitch-client:twitch-client-secret)
      --twitch-client string             Client ID to act as
      --twitch-client-secret string      Secret for the Client ID
      --twitch-token string              OAuth token valid for client (fallback if no token was set in interface)
  -v, --validate-config                  Loads the config, logs any errors and quits with status 0 on success
      --version                          Prints current version and exits

```

## Upgrade from `v2.x` to `v3.x`

With the release of `v3.0.0` the bot changed a lot introducing a new storage format. As that storage backend is not compatible with the `v2.x` storage you need to migrate it manually before starting a `v3.x` bot version the first time.

**Before starting the migration make sure to fully stop the bot!**

This section assumes you were starting your bot the following way:

```console
# twitch-bot --storage-file storage.json.gz --twitch-client <clientid> --twitch-client-secret <secret>
```

To execute the migration we need to provide the same `storage-encryption-pass` or `twitch-client` / `twitch-client-secret` combination if no `storage-encryption-pass` was used.

```console
# twitch-bot --storage-database storage.db --twitch-client <clientid> --twitch-client-secret <secret> migrate-v2 storage.json.gz
WARN[0000] No storage encryption passphrase was set, falling back to client-id:client-secret
WARN[0000] Module registered unhandled query-param type  module=status type=integer
WARN[0000] Overlays dir not specified, no dir or non existent  dir=
INFO[0000] Starting migration...                         module=variables
INFO[0000] Starting migration...                         module=mod_punish
INFO[0000] Starting migration...                         module=mod_overlays
INFO[0000] Starting migration...                         module=mod_quotedb
INFO[0000] Starting migration...                         module=core
INFO[0000] Starting migration...                         module=counter
INFO[0000] Starting migration...                         module=permissions
INFO[0000] Starting migration...                         module=timers
INFO[0000] v2 storage file was migrated
```

If you see the `v2 storage file was migrated` message the contents of your old storage file were migrated to the new `storage-database`. The old file is not modified in this step.

Afterwards your need to adjust the start parameters of the bot:

```console
# twitch-bot --storage-database storage.db --twitch-client <clientid> --twitch-client-secret <secret>
```
