Definitions

It is important to understand these definitions in order to read the rest of the doc or to use the package.

Client

Anything that can send messages or updates to the bot is called a client. This can be a user, another bot or a channel. Users can send messages to the bot in private chats or groups, bots can send messages in groups and channels can send messages in channels (of which our bot is a member). So when we talk about a client we are talking about one of these three.

Telegram State

A client can be working with the bot in different settings. For example, a user can send messages to the bot in a private chat or in a group or different groups. A bot can send messages visible to our bot in different groups. These should be handled separately. If a user is working with the bot in 2 groups at the same time, we do not want their interactions with the bot in one group to interfere with their interactions with the bot in the other group or in the private chat. Here comes the Telegram State.

Telegram State holds information about a client, the chat in which they are using the bot and some other auxiliary data for helping the bot to handle updates. These data are stored in the database under the model TelegramState. Please read its full documentation from here.

Processor

Whenever an update is received from Telegram, a Telegram State object will be assigned to it. One will be created if there is not any for this particular client and chat. Now we have a bot, an update to process and a state holding information about the client. It is time to process all of these information. A processor is a function that takes these 3 object (namely the bot, the update and the state) and processes it. Processors can respond to an update in whatever way they want. They can modify the state, they can send a message to this client or they can do nothing. Please read full documentation of processors from here.
