Configuration

# upgrade.
config_version: 2

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
• formatDuration <duration> <hours> <minutes> <seconds> - Returns a formated duration. Pass empty strings to leave out the part: {{ formatDuration .dur "hours" "minutes" "" }} yields N hours, M minutes
• 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.
• streamUptime <username> - Returns the duration the stream is online (causes an error if no current stream is found)
• 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

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:

{
  "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:

  - actions:
    - type: script
      attributes:
        command: [/usr/bin/bash, -c, "jq . >&2"]
    match_channels: ['#tezrian']
    match_message: '^!test'
