Functions ¶
func BoolTweakOr ¶
BoolTweakOr returns the named tweak as a boolean, and returns `def` on failure.
func ValidateRule ¶
ValidateRule checks the rule for errors. These follow from Sytests and the specification.
Types ¶
type AccountRuleSets ¶
type AccountRuleSets struct {
Global RuleSet `json:"global"` // Required
}
An AccountRuleSets carries the rule sets associated with an account.
func DefaultAccountRuleSets ¶
func DefaultAccountRuleSets(localpart string, serverName gomatrixserverlib.ServerName) *AccountRuleSets
DefaultAccountRuleSets is the complete set of default push rules for an account.
type Action ¶
type Action struct {
// Kind is the type of action. Has custom encoding in JSON.
Kind ActionKind `json:"-"`
// Tweak is the property to tweak. Has custom encoding in JSON.
Tweak TweakKey `json:"-"`
// Value is some value interpreted according to Kind and Tweak.
Value interface{} `json:"value"`
}
An Action is (part of) an outcome of a rule. There are (unofficially) terminal actions, and modifier actions.
func (*Action) MarshalJSON ¶
func (*Action) UnmarshalJSON ¶
type ActionKind ¶
type ActionKind string
ActionKind is the primary discriminator for actions.
const ( UnknownAction ActionKind = "" // NotifyAction indicates the clients should show a notification. NotifyAction ActionKind = "notify" // DontNotifyAction indicates the clients should not show a notification. DontNotifyAction ActionKind = "dont_notify" // CoalesceAction tells the clients to show a notification, and // tells both servers and clients that multiple events can be // coalesced into a single notification. The behaviour is // implementation-specific. CoalesceAction ActionKind = "coalesce" // SetTweakAction uses the Tweak and Value fields to add a // tweak. Multiple SetTweakAction can be provided in a rule, // combined with NotifyAction or CoalesceAction. SetTweakAction ActionKind = "set_tweak" )
func ActionsToTweaks ¶
func ActionsToTweaks(as []*Action) (ActionKind, map[string]interface{}, error)
ActionsToTweaks converts a list of actions into a primary action kind and a tweaks map. Returns a nil map if it would have been empty.
type Condition ¶
type Condition struct {
// Kind is the primary discriminator for the condition
// type. Required.
Kind ConditionKind `json:"kind"`
// Key indicates the dot-separated path of Event fields to
// match. Required for EventMatchCondition and
// SenderNotificationPermissionCondition.
Key string `json:"key,omitempty"`
// Pattern indicates the value pattern that must match. Required
// for EventMatchCondition.
Pattern string `json:"pattern,omitempty"`
// Is indicates the condition that must be fulfilled. Required for
// RoomMemberCountCondition.
Is string `json:"is,omitempty"`
}
A Condition dictates extra conditions for a matching rules. See ConditionKind.
type ConditionKind ¶
type ConditionKind string
ConditionKind represents a kind of condition.
SPEC: Unrecognised conditions MUST NOT match any events, effectively making the push rule disabled.
const ( UnknownCondition ConditionKind = "" // EventMatchCondition indicates the condition looks for a key // path and matches a pattern. How paths that don't reference a // simple value match against rules is implementation-specific. EventMatchCondition ConditionKind = "event_match" // ContainsDisplayNameCondition indicates the current user's // display name must be found in the content body. ContainsDisplayNameCondition ConditionKind = "contains_display_name" // RoomMemberCountCondition matches a simple arithmetic comparison // against the total number of members in a room. RoomMemberCountCondition ConditionKind = "room_member_count" // SenderNotificationPermissionCondition compares power level for // the sender in the event's room. SenderNotificationPermissionCondition ConditionKind = "sender_notification_permission" )
type EvaluationContext ¶
type EvaluationContext interface {
// UserDisplayName returns the current user's display name.
UserDisplayName() string
// RoomMemberCount returns the number of members in the room of
// the current event.
RoomMemberCount() (int, error)
// HasPowerLevel returns whether the user has at least the given
// power in the room of the current event.
HasPowerLevel(userID, levelKey string) (bool, error)
}
An EvaluationContext gives a RuleSetEvaluator access to the environment, for rules that require that.
type Rule ¶
type Rule struct {
// RuleID is either a free identifier, or the sender's MXID for
// SenderKind. Required.
RuleID string `json:"rule_id"`
// Default indicates whether this is a server-defined default, or
// a user-provided rule. Required.
//
// The server-default rules have the lowest priority.
Default bool `json:"default"`
// Enabled allows the user to disable rules while keeping them
// around. Required.
Enabled bool `json:"enabled"`
// Actions describe the desired outcome, should the rule
// match. Required.
Actions []*Action `json:"actions"`
// Conditions provide the rule's conditions for OverrideKind and
// UnderrideKind. Not allowed for other kinds.
Conditions []*Condition `json:"conditions"`
// Pattern is the body pattern to match for ContentKind. Required
// for that kind. The interpretation is the same as that of
// Condition.Pattern.
Pattern string `json:"pattern"`
}
A Rule contains matchers, conditions and final actions. While evaluating, at most one rule is considered matching.
Kind and scope are part of the push rules request/responses, but not of the core data model.
type RuleSet ¶
type RuleSet struct {
Override []*Rule `json:"override,omitempty"`
Content []*Rule `json:"content,omitempty"`
Room []*Rule `json:"room,omitempty"`
Sender []*Rule `json:"sender,omitempty"`
Underride []*Rule `json:"underride,omitempty"`
}
A RuleSet contains all the various push rules for an account. Listed in decreasing order of priority.
func DefaultGlobalRuleSet ¶
func DefaultGlobalRuleSet(localpart string, serverName gomatrixserverlib.ServerName) *RuleSet
DefaultGlobalRuleSet returns the default ruleset for a given (fully qualified) MXID.
type RuleSetEvaluator ¶
type RuleSetEvaluator struct {
// contains filtered or unexported fields
}
A RuleSetEvaluator encapsulates context to evaluate an event against a rule set.
func NewRuleSetEvaluator ¶
func NewRuleSetEvaluator(ec EvaluationContext, ruleSet *RuleSet) *RuleSetEvaluator
NewRuleSetEvaluator creates a new evaluator for the given rule set.
func (*RuleSetEvaluator) MatchEvent ¶
func (rse *RuleSetEvaluator) MatchEvent(event *gomatrixserverlib.Event) (*Rule, error)
MatchEvent returns the first matching rule. Returns nil if there was no match rule.
