Feature Request: System Message Type

[su-chang]

Feature Request

System Message is important type for IM system, e.g. WeChat, WeCom, WhatsApp and so on. But we can not find a message type could stand for System Message below.

puppet/src/schemas/message.ts

Lines 1 to 23 in 33af5a4

	/**
	* Wechaty Puppet Unified Schema for Message
	*/
	export enum MessageType {
	Unknown = 0,
	Attachment = 1, // Attach(6),
	Audio = 2, // Audio(1), Voice(34)
	Contact = 3, // ShareCard(42)
	ChatHistory = 4, // ChatHistory(19)
	Emoticon = 5, // Sticker: Emoticon(15), Emoticon(47)
	Image = 6, // Img(2), Image(3)
	Text = 7, // Text(1)
	Location = 8, // Location(48)
	MiniProgram = 9, // MiniProgram(33)
	GroupNote = 10, // GroupNote(53)
	Transfer = 11, // Transfers(2000)
	RedEnvelope = 12, // RedEnvelopes(2001)
	Recalled = 13, // Recalled(10002)
	Url = 14, // Url(5)
	Video = 15, // Video(4), Video(43)
	Post = 16, // Moment, Channel, Tweet, etc
	}

BTW, the number in bracket is out of style, Wechaty is not only for WeChat now.

For WeChat we could find SysNotice and Sys in WechatMessageType, but these types could not used to other IM.

puppet/src/schemas/message.ts

Lines 78 to 79 in 33af5a4

	SysNotice = 9999,
	Sys = 10000,

So let's add a new type, named System for all IM in Wechaty system.

Example

System message in WeCom.
