- mychannel
# 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
rules: # See below for examples
- actions: # Array of actions to take when this rule matches
# Issue a ban on the user who wrote the chat-line
- ban: "reason of ban"
# Command to execute for the chat message, must return an JSON encoded array of actions
- command: [/bin/bash, -c, "echo '[{\"respond\": \"Text\"}]'"]
# Modify an internal counter value (does NOT send a chat line)
- counter: "counterid" # String to identify the counter, applies templating
counter_step: 1 # Integer, can be negative or positive, default: +1
# Issue a delete on the message caught
- delete_message: true # Bool, set to true to delete
# Send responding message to the channel the original message was received in
- respond: 'Hello chatter' # String, applies templating
# Issue a timeout on the user who wrote the chat-line
- timeout: 1s # Duration value: 1s / 1m / 1h
# Add a cooldown to the command (not to trigger counters twice, ...)
cooldown: 1s # Duration value: 1s / 1m / 1h
# Disable actions on this rule if the user has an active permit
disable_on_permit: false
# Disable actions on this rule if the user has one of 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
- `channelCounter <counter name>` - Wraps the counter name into a channel specific counter name including the channel name
- `counterValue <counter name>` - Returns the current value of the counter which identifier was supplied
- `fixUsername <username>` - Ensures the username no longer contains the `@` prefix
- `group <idx>` - Gets matching group specified by index from `match_message` regular expression
- `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
## 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"
}
```
