Televiewshka

Note: as for now, this is neither stable nor working code. Being Created in ... purposes it is a subject for further updates and improvements

viewshka - Russian noun: informal of eng. "view", obtained by adding a diminutive suffix "shka"

Televiewshka allows you develop UI & logic for telegram bots with class based views. In views you can define its content and how user actions and replies must be handled on it. When all stuff related particular step in user flow is held in one class, you can clearly see relationship between components

Televiewshka supposed to be developed in such a manner to be compatible with a bunch of libs and frameworks for telegram bot api widely used by community

I guess I should write few adaptors for this purpose someday

(Supposed) Example

from telebot import TeleBot
from televiewshka import KeyboardView, \
    KeyboardLayout, Button, adaptors, handler, render

# create adaptor for your lib/framework
bot = TeleBot("super-secret")
bot = adaptors.create_adaptor(bot)


# specify views
class FirstView(KeyboardView):
    @bot.action_handler(action="next")
    def go_next(self, query: Query):
        return render("NextView", inplace=True, param=42)

    @staticmethod
    def render():
        return KeyboardLayout(
            keyboard = (
                Button("Go next", on_click="next"),
            ))


class NextView(KeyboardView):
    @bot.action_handler()
    def back(self, query: Query):
        return render(FirstView, inplace=True)

    @staticmethod
    def render(param: int):
        return KeyboardLayout(
            text=f"Passed param: {param}",
            keyboard = (
                Button("Go back", on_click="back"),
            ))

# run the bot
bot.start()
