Telegrask

Welcome to Telegrask’s documentation!

User’s Guide

Getting Started

Installing

To install Telegrask run following command:

$ python3 -m pip install Telegrask

Project Initialization

You can manually create project structure or use built-in project initializer:

$ python3 -m telegrask init <PROJECT_NAME>

Usage Basics

Main goal of this framework is use handlers decorators and make bot creating more intuitive.

Simplest Example

Hello World bot example in Telegrask:

from telegrask import Telegrask

bot = Telegrask("TOKEN")


@bot.command("hello", help='display "Hello, World!"')
def hello_command(update, context):
    update.message.reply_text("Hello, World!")


if __name__ == "__main__":
    bot.run(debug=True)

and equivalent code in pure python-telegram-bot library:

from telegram.ext import Updater, CommandHandler
from telegram import ParseMode
import logging

logging.basicConfig(format="%(levelname)s - %(message)s", level=logging.DEBUG)
logger = logging.getLogger(__name__)


def hello_command(update, context):
    update.message.reply_text("Hello, World!")


def help_command(update, context):
    help_content = """*Available commands*

/hello
display "Hello, World!"

/help
display this message
"""
    update.message.reply_text(help_content, parse_mode=ParseMode.MARKDOWN)


def main():
    global updater
    updater = Updater("BOT_TOKEN")
    dispatcher = updater.dispatcher
    dispatcher.add_handler(CommandHandler("hello", hello_command))
    dispatcher.add_handler(CommandHandler(["help", "start"], help_command))
    updater.start_polling()
    updater.idle()


if __name__ == "__main__":
    main()

Handlers Decorators

Each handler decorator is a child method of Telegrask class, so you need to have an object of this class first.

from telegram import Update
from telegram.ext import CallbackContext

bot = Telegrask("TOKEN")

@command

Handler for commands (messages starting with / prefix, e.g. /cmd).

@bot.command("command_name", help="command help message")
def callback_function(update: Update, context: CallbackContext):
    pass

Parameters:

• commands: Union[str, list] - command or list of commands which will use this function as callback

• help: str - description for command which will be included in automaticly generated /help command message

• allow_without_prefix: bool = False - handle command also without / prefix, e.g. /cmd and cmd

@message

Handler for messages.

from telegram.ext import Filters

@bot.message(...)
def callback_function(update: Update, context: CallbackContext):
    pass

Parameters:

• filters: Filters - any combination of Filters from python-telegram-bot library

@message_regex

Handler for messages by regexes instead of filters.

@bot.message_regex(r"regex or just text")
def callback_function(update: Update, context: CallbackContext):
    pass

Parameters:

• regex: Pattern - regular expression to filter a message or just text

@inline_query

Handler for inline queries.

from telegrask import InlineQuery

@bot.inline_query
def inline(query: InlineQuery):
    pass
