Inline Telegram Bot API library

Work in progress, there is an application for testing design of this library: https://github.com/iokasimov/elections-bot


This library provides ORM-like toolkit to deal with methods of Telegram Bot API - types and classes were designed in terms of Objects and their Properties.

Objects description:

  • Update: object that webhook consumes, can be either an incoming Message, Callback query or Moving in/out some group chat.

  • Message: every object contains Origin and Content, can be either Direct, Forwarded or Replied.

  • Content: can be either Command, Text, File, Poll, Contact, Location or Venue.

  • File: Can be either Audio, Document, Photo, Video or Voice.

  • Origin: indicates where is message from, contains Sender.

  • Callback: this is what webhook consumes on pressing inline keyboard's button.

  • Group: can be either Basic or Super, contains chat ID and title.

  • Moving: indicates which Sender leaved some chat or which Senders joined, also contains Group.

  • Sender: can be either a Bot or a Human.

  • Member: shows the status of a bot or user in group chat, contains Sender.

Properties description:

  • Accessible: provides lens for objects within other objects.

  • Identifiable: provides identification of objects to use it for requests.

  • Persistable: provides persist methods that returns you value of some type on success. The "on success" definition is rather vague, for example: if you try to edit object and it remains the same, nothing will returns. Use persist_ to not decode API answer (because if decoding fails the next applicative or monadic action will not happen).

Available persistent actions over objects:

  • Forward: only Message.
  • Reply: everything that you can Send.
  • Send: Text, Keyboard, Audio, Document, Video, Voice, Photo, Location, Live Location, Poll.
  • Delete: Message.
  • Edit: Text, Keyboard, Live Location.
  • Stop: Live Location, Poll.

See payload and returning value in Persistable instances.

Also, you can Forward, Reply and Send objects Silently.

Also, there are special persistent actions for chat members:

  • Kick: kick user from group, user can not return unless unbanned first
  • Restrict: change what some member in group can do.
  • Promote: change what some admin in group can do.

Simple examples

Sending inline keyboard

let text = "Just click any button..."
let button1 = Button "Press me!" $ Callback "1"
let button2 = Button "Or press me!" $ Callback "2"
let button3 = Button "No, press me!" $ Callback "3"
let keyboard = Inline [button1, button2, button3]
void . persist . Send chat_id $ text :&: keyboard

Handling pressing buttons with notification

webhook (Query _ (Datatext cbq_id _ _ bn)) = do
    let text = "The button you pressed is: " <> bn
    persist $ Trigger @Notification cbq_id text

Deleting all incoming messages

webhook (Incoming _ msg) = do
    let chat_id = ident $ access @Origin msg
    persist (Delete @Message chat_id $ ident msg)
