## Configuration
```yaml
---
# This must be the config version you've used below. Current version
# is version 2 so probably keep it at 2 until the bot tells you to
# upgrade.
config_version: 2
# List of strings: Either Twitch user-ids or nicknames (best to stick
# with IDs as they can't change while nicknames can be changed every
# 60 days). Those users are able to use the config editor web-interface.
bot_editors: []
# List of channels to join. Channels not listed here will not be
# joined and therefore cannot be actioned on.
channels:
- mychannel
# Enable HTTP server to control plugins / core functionality
# if unset the server is not started, to change the bot must be restarted
http_listen: "127.0.0.1:3000"
# Allow moderators to hand out permits (if set to false only broadcaster can do this)
permit_allow_moderator: true
# How long to permit on !permit command
permit_timeout: 60s
# Variables are made available in templating (for example useful to disable several
# rules at once using the `disable_on_template` directive)
# Supported data types: Boolean, Float, Integer, String
variables:
myvariable: true
anothervariable: "string"
# List of auto-messages. See documentation for details or use
# web-interface to configure.
auto_messages:
- channel: 'mychannel' # String, channel to send message to
message: 'Automated message' # String, message to send
use_action: true # Bool, optional, send message as action (`/me <message>`)
# Even though all of these are optional, at least one MUST be specified for the entry to be valid
cron: '*/10 * * * *' # String, optional, cron syntax when to send the message
message_interval: 3 # Integer, optional, how many non-bot-messages must be sent in between
only_on_live: true # Boolean, optional, only send the message when channel is live
# Disable message using templating, must yield string `true` to disable the automated message
disable_on_template: '{{ ne .myvariable true }}'
# List of rules. See documentation for details or use web-interface
# to configure.
rules: # See below for examples
- actions: # Array of actions to take when this rule matches

# https://github.com/Luzifer/twitch-bot/wiki/Actors
- type: "<actor type>"
attributes:
key: value
# Add a cooldown to the rule in general (not to trigger counters twice, ...)
# Using this will prevent the rule to be executed in all matching channels
# as long as the cooldown is active.
cooldown: 1s # Duration value: 1s / 1m / 1h
# Add a cooldown to the rule per channel (not to trigger counters twice, ...)
# Using this will prevent the rule to be executed in the channel it was triggered
# which means other channels are not affected.
channel_cooldown: 1s # Duration value: 1s / 1m / 1h
# Add a cooldown to the rule per user (not to trigger counters twice, ...)
# Using this will prevent the rule to be executed for the user which triggered it
# in any of the matching channels, which means other users can trigger the command
# while that particular user cannot

# Do not apply cooldown for these badges

## Templating
There are certain variables available in the strings with templating enabled:
- `channel` - Channel the message was sent to, only available for regular messages not events
- `msg` - The message object, used in functions, should not be sent to chat
- `permitTimeout` - Value of `permit_timeout` in seconds
- `username` - The username of the message author
Additionally there are some functions available in the templates:
- `arg <idx>` - Takes the message sent to the channel, splits by space and returns the Nth element
- `botHasBadge <badge>` - Checks whether bot has the given badge in the current channel
- `channelCounter <counter name>` - Wraps the counter name into a channel specific counter name including the channel name
- `concat <delimiter> <...parts>` - Join the given string parts with delimiter
- `counterValue <counter name>` - Returns the current value of the counter which identifier was supplied
- `displayName <username> [fallback]` - Returns the display name the specified user set for themselves
- `fixUsername <username>` - Ensures the username no longer contains the `@` or `#` prefix
- `followDate <from> <to>` - Looks up when `from` followed `to`
- `group <idx> [fallback]` - Gets matching group specified by index from `match_message` regular expression, when `fallback` is defined, it is used when group has an empty match
- `recentGame <username> [fallback]` - Returns the last played game name of the specified user (see shoutout example) or the `fallback` if the game could not be fetched. If no fallback was supplied the message will fail and not be sent.
- `tag <tagname>` - Takes the message sent to the channel, returns the value of the tag specified
- `toLower <string>` - Converts the given string to lower-case
- `toUpper <string>` - Converts the given string to upper-case
- `variable <name> [default]` - Returns the variable value or default in case it is empty
For some events special variables are made available:
- `title` - Available in `title_update` - The new stream title
- `category` - Available in `category_update` - The new stream category
## Command executions
Your command will get a JSON object passed through `stdin` you can parse to gain details about the message. It is expected to yield an array of actions on `stdout` and exit with status `0`. If it does not the action will be marked failed. In case you need to output debug output you can use `stderr` which is directly piped to the bots `stderr`.
This is an example input you might get on `stdin`:
```json
{
"badges": {
"glhf-pledge": 1,
"moderator": 1
},
"channel": "#tezrian",
"message": "!test",
"tags": {
"badge-info": "",
"badges": "moderator/1,glhf-pledge/1",
"client-nonce": "6801c82a341f728dbbaad87ef30eae49",
"color": "#A72920",
"display-name": "Luziferus",
"emotes": "",
"flags": "",
"id": "dca06466-3741-4b22-8339-4cb5b07a02cc",
"mod": "1",
"room-id": "485884564",
"subscriber": "0",
"tmi-sent-ts": "1610313040489",
"turbo": "0",
"user-id": "69699328",
"user-type": "mod"
},
"username": "luziferus"
}
```
The example was dumped using this action:
