Filters

Filters are a beta feature and may be buggy. Things may change at any time, including conditions being dropped or filters being removed all together.

If you have any problems with filters, or any suggestions, please open a thread in #feedback or #support in the support server.

Filters are a new, more flexible way to control what messages can be starred or sent to autostar channels. Before reading, it's a good idea to familiarize yourself with the terminology used:

• Filter Group: A filter group is a collection of filters. A single filter group can be applied to a starboard or an autostar channel. A filter group is identified by its name.

• Filter: A filter is a collection of conditions. All filters are inside a filter group (they cannot be by themselves), and are identified by their position within that group (e.g. 1 or 2).

• Filter Condition: A single condition of a filter, such as user-has-all-of (meaning that the user, or message author, must have all of a set of roles).

Currently, filters can only be applied to starboards and autostar channels. In the future, you may be able to use filters as a condition for whether an override should apply (rather than just applying overrides on a channel basis), as well as for custom leaderboards (another planned feature).

Conditions

The conditions for a filter are split into three categories (called contexts): Default, Message, and Vote. The reason for this is that some conditions (such as voter-has-all-of) make no sense in some situations, like autostar channels.

Currently, there are only two contexts that occur: starboards and autostar channels.

A starboard utilizes all of the contexts (Default, Message, and Vote). Autostar channels utilize only the first two (Default and Message). If a filter has conditions inside of a context that isn't considered for a certain situation, then it will be assumed to pass.

Default Context

These are conditions that are always valid. These conditions concern a "user" - for autostar channels and starboards, this is the message author.

user-has-all-of	A list of roles that the user must have
user-has-some-of	A list of roles that the user must have at least one of
user-missing-all-of	A list of roles that the user must not have (the user cannot have any of these roles)
user-missing-some-of	A list of roles that the user must be missing at least one of (the user cannot have all of these roles)
user-is-bot	A condition that either requires the user to be a bot or be a human.

Message Context

These are conditions that are valid when a message is being considered. Both autostar channels and starboards consider this context.

in-channel	A list of channels that the message must be in.
not-in-channel	A list of channels that the message cannot be in.
in-channel-or-sub-channels	A list of channels that the message must be in, including that channels sub-channels.
not-in-channel-or-sub-channels	A list of channels that the message cannot be in, including that channels sub-channels.
min-attachments	The message must have at least this many attachments.
max-attachments	The message must have at most this many attachments.
min-length	The message must be at least this long.
max-length	The message must be at most this long.
matches	(Premium) the message must match this regex.
not-matches	(Premium) the message must not match this regex.

Vote Context

This context is considered for votes (reactions). Only starboards consider this context, everything else just assumes that these conditions pass.

voter-has-all-of	A list of roles that the voter must have
voter-has-some-of	A list of roles that the voter must have at least one of
voter-missing-all-of	A list of roles that the voter must not have (the voter cannot have any of these roles)
voter-missing-some-of	A list of roles that the voter must be missing at least one of (the voter cannot have all of these roles)
older-than	The message must be older than this, at the time that the vote was added.
newer-than	The message must be newer than this, at the time that the vote was added.
