Find your bot in Telegram by name and say him Hi.

Use screen command, to run bot in background.

By default bot does nothing, plugins is used to extend functionality and interact with users. We made few classic plugins for Joker, like Hello and more complex one Temp, feel free to use them and add new.

To add plugin, create new class extending Joker\Plugin and connect it with $joker->plug( array ) command before main loop. Add methods like on[Action][Action]( Joker\Parser\Update $update ). These methods will be called when all actions is found in request. Actions can be:

• Public - public requests
• Private - non-public requests
• Group - group, supergroup and channel requests
• Message - all requests contains message, except Empty.
• Sticker - stickers or replies with sticker
• Text - has text
• Photo - has photo
• Caption - has caption, usually on photo
• Animation - has animation
• Audio - has audio
• Document - has document
• Video - has video
• Voice - has voice
• Contact - has contact
• Dice - is a rolled dice
• Game - contains game
• Reply - is a reply
• Forward - is a forwarded message
• Poll - polls
• Edit - edited message
• Location - location
• Join - user joined the chat
• Leave - user leaves the chat
• Pin - new pinned message
• Entities - has entities attached
• Viabot - message is sent via bot
• Empty - empty requests, you can use this for processing timers

For example, onPrivateSticker or onStickerPrivate will be called when both sticker and private is found in request.

Parameter of this method Joker\Parser\Update $update is used to access different parts of updates and react.

All details are described in Joker\Parser classes, to get information from update use methods with same names as in Telegram API types on $update object, for example $update->message()->chat()->username() will return username of chat, where message was sent to.

Actions can be called from update, for example $update->answerMessage() or $update->answerSticker() is a shortcut to answer same channel or private user, by message or sticker. Other actions can be found in Joker\Parser\Update class and others.

Return value of plugin method can be:

• Joker\Bot::PLUGIN_NEXT or true or null- (default) process next plugin in chain
• Joker\Bot::PLUGIN_BREAK or false - do not process plugin chain anymore.

More information about existing plugins functionality can be found here.
