Functions

func ItemsToPlain

func ItemsToPlain(items []MessageItem) string

ItemsToPlain joins together the MessageItems' Text using newlines Used implement the rich sender API by redirecting to the plain sender implementation

Types

type ConfigProp

type ConfigProp interface {
	SetFromProp(propValue string) error
	GetPropValue() (string, error)
}

ConfigProp interface is used to de-/serialize structs from/to a string representation

type ConfigQueryResolver

type ConfigQueryResolver interface {
	Get(string) (string, error)
	Set(string, string) error
	QueryFields() []string
}

ConfigQueryResolver is the interface used to get/set and list service config query fields

type CustomURLService

type CustomURLService interface {
	Service
	GetConfigURLFromCustom(customURL *url.URL) (serviceURL *url.URL, err error)
}

CustomURLService is the interface that needs to be implemented to support custom URLs in services

type EnumFormatter

type EnumFormatter interface {
	Print(e int) string
	Parse(s string) int
	Names() []string
}

EnumFormatter translate enums between strings and numbers

type Enummer

type Enummer interface {
	Enums() map[string]EnumFormatter
}

Enummer contains fields that have associated EnumFormatter instances

type Field

type Field struct {
	Key   string
	Value string
}

Field is a Key/Value pair used for extra data in log messages

func FieldsFromMap

func FieldsFromMap(fieldMap map[string]string, sorted bool) []Field

FieldsFromMap creates a Fields slice from a map, optionally sorting keys

type Generator

type Generator interface {
	Generate(service Service, props map[string]string, args []string) (ServiceConfig, error)
}

Generator is the interface for tools that generate service configurations from a user dialog

type MessageItem

type MessageItem struct {
	Text      string
	Timestamp time.Time
	Level     MessageLevel
	Fields    []Field
}

MessageItem is an entry in a notification being sent by a service

func (*MessageItem) WithField

func (mi *MessageItem) WithField(key, value string) *MessageItem

WithField appends the key/value pair to the message items fields

type MessageLevel

type MessageLevel uint8

MessageLevel is used to denote the urgency of a message item

const (
	// Unknown is the default message level
	Unknown MessageLevel = iota
	// Debug is the lowest kind of known message level
	Debug
	// Info is generally used as the "normal" message level
	Info
	// Warning is generally used to denote messages that might be OK, but can cause problems
	Warning
	// Error is generally used for messages about things that did not go as planned
	Error

	// MessageLevelCount is used to create arrays that maps levels to other values
	MessageLevelCount = int(messageLevelCount)
)

func (MessageLevel) String

func (level MessageLevel) String() string

type MessageLimit

type MessageLimit struct {
	ChunkSize      int
	TotalChunkSize int

	// Maximum number of chunks (including the last chunk for meta data)
	ChunkCount int
}

MessageLimit is used for declaring the payload limits for services upstream APIs

type Params

type Params map[string]string

Params is the string map used to provide additional variables to the service templates

func (Params) SetMessage

func (p Params) SetMessage(message string)

SetMessage sets the "message" param to the specified value

func (Params) SetTitle

func (p Params) SetTitle(title string)

SetTitle sets the "title" param to the specified value

func (Params) Title

func (p Params) Title() (title string, found bool)

Title returns the "title" param
