telekit 2.1.0

Declarative, developer-friendly library for building Telegram bots

Telekit

Telekit is a declarative, developer-friendly library for building Telegram bots. It gives developers a dedicated Sender for composing and sending messages and a Chain for handling dialogue between the user and the bot. The library also handles inline keyboards and callback routing automatically, letting you focus on the bot's behavior instead of repetitive tasks.

import telekit

class MyStartHandler(telekit.Handler):
    @classmethod
    def init_handler(cls):
        cls.on.command('start').invoke(cls.handle_start)

    def handle_start(self):
        self.chain.sender.set_text("Hello!")
        self.chain.sender.set_photo("robot.png")
        self.chain.send()

telekit.Server("BOT_TOKEN").polling()

Send "Hello!" with a photo on /start

Telekit comes with a built-in DSL, allowing developers to create fully interactive bots with minimal code. It also integrates Jinja, giving you loops, conditionals, expressions, and filters to generate dynamic content.

@ main {
    title   = "🎉 Fun Facts Quiz";
    message = "Test your knowledge with 10 fun questions!";

    buttons {
        question_1("Start Quiz");
    }
}

Even in its beta stage, Telekit accelerates bot development, offering typed command parameters, text styling via Bold(), Italic(), built-in emoji game results for 🎲 🎯 🏀 ⚽ 🎳 🎰, and much more out of the box. Its declarative design makes bots easier to read, maintain, and extend.

Key features:

• Declarative bot logic with chains for effortless handling of complex conversations
• Ready-to-use DSL for FAQs and other interactive scripts
• Automatic handling of message formatting via Sender and callback routing
• Deep Linking support with type-checked Command Parameters for flexible user input
• Built-in Permission and Logging system for user management
• Seamless integration with pyTelegramBotAPI
• Fast to develop and easy-to-extend code

Overview

Telekit is a library for building Telegram bots where dialogs look like normal method calls. No bulky state machines. No scattered handlers.

The idea is simple: you point to the next step — Telekit calls it when the user replies.

Entries

No state machines. Just tell Telekit which method should handle the next user message.

def handle(self):
    self.chain.sender.set_text("👋 Hello! What is your name?")
    self.chain.set_entry_text(self.handle_name)
    self.chain.send()

def handle_name(self, name: str):
    self.chain.sender.set_text(f"Nice to meet you, {name}!")
    self.chain.send()

The handle method sends a message and registers handle_name as the next step using set_entry_text. When the user replies, Telekit automatically calls handle_name and passes the user's message as a plain str argument.

That's it. No enums. No manual state tracking. No boilerplate.

Inline Keyboards

Buttons can either return a value or call a method directly.

Choice keyboard — map button labels to values. The selected value is passed straight into your handler:

self.chain.set_inline_choice(
    self.on_choice,
    choices={
        "Option 1": "Value 1",
        "Option 2": "Value 2",
        "Option 3": [3, "Yes, it's an array"],
    }
)

def on_choice(self, choice: str | list):
    print(f"{choice!r}") # "Value 1", "Value 2" or [3, "Yes, it's an array"]

Inside on_choice, you receive exactly what you defined in choices: a string, list, number, function — anything.

Callback keyboard — each button calls its own method:

self.chain.set_inline_keyboard({
    "« Back": self.display_previous_page,
    "Next »": self.display_next_page,
})

Useful for pagination, navigation, or menus.

Command Parameters

Telekit can parse and validate command parameters for you.

from telekit.parameters import *

class GreetHandler(telekit.Handler):
    @classmethod
    def init_handler(cls) -> None:
        cls.on.command("greet", params=[Int(), Str()]).invoke(cls.handle)

    def handle(self, age: int | None = None, name: str | None = None):
        if age is None or name is None:
            self.chain.sender.set_text("Usage: /greet <age> <name>")
        else:
            self.chain.sender.set_text(f"Hello, {name}! You are {age} years old. Next year you'll turn {age + 1} 😅")
        self.chain.send()

Now /greet 64 "Alice Reingold" or /greet 128 Dracula are parsed automatically.

[!INFO] If arguments are invalid or missing, you simply receive None and decide how to respond.

Dialogue

Dialogs are built as a chain of steps. Each method waits for the user before continuing.

class DialogueHandler(telekit.Handler):

    @classmethod
    def init_handler(cls) -> None:
        cls.on.text("hello", "hi", "hey").invoke(cls.handle_hello)

    def handle_hello(self) -> None:
        self.chain.sender.set_text("👋 Hello! What is your name?")
        if self.user.first_name:
            self.chain.set_entry_suggestions([self.user.first_name])
        self.chain.set_entry_text(self.handle_name)
        self.chain.send()

    def handle_name(self, name: str) -> None:
        self.user_name = name
        self.chain.sender.set_text("Nice! How are you feeling today?")
        self.chain.set_entry_text(self.handle_feeling)
        self.chain.send()

    def handle_feeling(self, feeling: str) -> None:
        self.chain.sender.set_text(f"Got it, {self.user_name.title()}! You feel: {feeling}")
        self.chain.set_inline_keyboard({"↺ Restart": self.handle_hello})
        self.chain.send()

How it works:

• The handler reacts to "hello", "hi", or "hey" (lowercase, UPPERCASE, or mixed).
• handle_hello asks for the user's name.
• set_entry_suggestions attaches the user's Telegram first_name as a suggestion button.
• handle_name stores the name in self.user_name.
• handle_feeling completes the flow and adds a "↺ Restart" button that routes back to the beginning.

It looks like regular Python. And reads like it too.

Sender

Want to add an image, document or an effect in a single line?

self.chain.sender.set_effect(Effect.HEART) # Add effect to message. Use enum or string
self.chain.sender.set_photo("robot.png") # Attach photo. URL, file_id, or path
self.chain.sender.set_document("README.md") # Attach document. URL, file_id, or path
self.chain.sender.set_text_as_document("Hello, this is a text document!") # Convert string to text document
self.chain.sender.send_chat_action(ChatAction.TYPING) # Send chat action. Use enum or string

[!NOTE] Telekit automatically decides whether to use 'bot.send_message' or 'bot.send_photo' based on the content

Styles

Telekit lets you describe formatting as objects instead of writing raw HTML or Markdown.

from telekit.styles import *

def handle(self) -> None:
    self.chain.sender.set_text(
        Bold("Text style examples:\n"),
        Stack(
            Bold("Bold text"),
            Italic("Italic text"),
            Bold(Italic("Bold + italic")),
            Link("Link", url="https://example.com"),
            BotLink("Deep link", username="MyBot", start="promo_42"),
            start="- {{index}}. ",
            sep=".\n",
        )
    )
    self.chain.send()

You describe structure. Telekit generates HTML or MarkdownV2 automatically:

<b>Text style examples:</b>

- 1. <b>Bold text</b>.
- 2. <i>Italic text</i>.
- 3. <b><i>Bold + italic</i></b>.
- 4. <a href="https://example.com">Link</a>.
- 5. <a href="https://t.me/MyBot?start=promo_42">Deep link</a>

No manual escaping. No broken formatting because of one missing character.

Telekit DSL

If you prefer not to write dialog logic in Python, you can use the built-in DSL with Jinja support.

import telekit

class QuizHandler(telekit.TelekitDSL.Mixin):
    @classmethod
    def init_handler(cls) -> None:
        cls.analyze_string(script)
        cls.on.command("start").invoke(cls.start_script)

script = """
$ timeout {
    time = 20; // 20 sec.
}

@ main {
    title   = "🎉 Fun Facts Quiz";
    message = "Test your knowledge with 10 fun questions!";

    buttons {
        next("Start Quiz");
    }
}

@ question_1 {
    title   = "🐶 Question 1";
    message = "Which animal is the fastest on land?";
    buttons {
        _lose("Elephant");
        next("Cheetah");       // correct answer
        _lose("Horse");
        _lose("Lion");
    }
}

/* ... */
"""

telekit.Server(BOT_TOKEN).polling()

Key features of the Telekit DSL:

• Scene-based architecture
• Anonymous scenes
• Automatic navigation stack management
• Input handling
• Images support and link buttons
• Template variables
• Custom variables

Example Bot

You can launch an example bot by running the following code:

import telekit

telekit.example(YOUR_BOT_TOKEN)

It includes example commands, dialogs, keyboards, and style usage.
