const bot = Wechaty.instance()

bot
.on('scan', (url, code)=>{
    let loginUrl = url.replace('qrcode', 'l')
    require('qrcode-terminal').generate(loginUrl)
    console.log(url)
})

.on('login', user=>{
    console.log(`${user} login`)
})

.on('friend', async function (contact, request){
    if(request){
        await request.accept()
        console.log(`Contact: ${contact.name()} send request ${request.hello}`)
    }
})

.on('message', async function(m){
    const contact = m.from()
    const content = m.content()
    const room = m.room()

    if(room){
        console.log(`Room: ${room.topic()} Contact: ${contact.name()} Content: ${content}`)
    } else{
        console.log(`Contact: ${contact.name()} Content: ${content}`)
    }

    if(m.self()){
        return
    }

    if(/hello/.test(content)){
        m.say("hello how are you")
    }

    if(/room/.test(content)){
        let keyroom = await Room.find({topic: "test"})
        if(keyroom){
            await keyroom.add(contact)
            await keyroom.say("welcome!", contact)
        }
    }

    if(/out/.test(content)){
        let keyroom = await Room.find({topic: "test"})
        if(keyroom){
            await keyroom.say("Remove from the room", contact)
            await keyroom.del(contact)
