Usage

Initalize

from teleflask import Teleflask

bot = Teleflask(API_KEY, app)

or

from teleflask import Teleflask

bot = Teleflask(API_KEY)
bot.init_app(app)

app being your flask app.

Usage

# use bot from initialize above
from teleflask.messages import TextMessage


@app.route("/")
def index():
    return "This is a normal Flask page."
# end def


# Register the /start command
@bot.command("start")
def start(update, text):
    # update is the update object. It is of type pytgbot.api_types.receivable.updates.Update
    # text is the text after the command. Can be empty. Type is str.
    return TextMessage("<b>Hello!</b> Thanks for using @" + bot.username + "!", parse_mode="html")
# end def


# register a function to be called for updates.
@bot.on_update
def foo(update):
    from pytgbot.api_types.receivable.updates import Update
    assert isinstance(update, Update)
    # do stuff with the update
    # you can use bot.bot to access the pytgbot.Bot's messages functions
    if not update.message:
        return
        # you could use @bot.on_message instead of this if.
    # end if
    if update.message.new_chat_member:
        return TextMessage("Welcome!")
    # end if
# end def

Short documentation

Functions and classes are explained in the docstrings in the sourcecode.

Teleflask

Teleflask is the full package, including all provided functionality.

Components

Functionality is separated into mixin classes. This means you can plug together a class with just the functions you need. The Teleflask class includes all of them.

Startup (teleflask.mixins.StartupMixin):

• app.add_startup_listener to let the given function be called on server/bot startup
• app.remove_startup_listener to remove the given function again
• @app.on_startup decorator which does the same as add_startup_listener.

Commands (teleflask.mixins.BotCommandsMixin):

• app.add_command to add command functions
• app.remove_command to remove them again.
• @app.command("command") decorator as alias to add_command
• @app.on_command("command") decorator as alias to add_command

Messages (teleflask.mixins.MessagesMixin):

• app.add_message_listener to add functions
• app.remove_message_listener to remove them again.
• @app.on_message decorator as alias to add_message_listener

Updates (teleflask.mixins.UpdatesMixin):

• app.add_update_listener to add functions to be called on incoming telegram updates.
• app.remove_update_listener to remove them again.
• @app.on_update decorator doing the same as add_update_listener

Execution order:

It will first check for registered commands (@command), next for messages listeners (@on_message) and finally for update listeners (@on_update).

Running bot commands

The normal pytgbot’s bot is available as .bot in your Teleflask instance:

from teleflask import Teleflask

bot = Teleflask(API_KEY, app)
bot.bot.send_message('@luckydonald', 'It works :D')  # please don't spam me :D
