Main interface
|
|
==============
|
|
|
|
The library itself is under the ``telethon/`` directory. The
|
|
``__init__.py`` file there exposes the main ``TelegramClient``, a class
|
|
that servers as a nice interface with the most commonly used methods on
|
|
Telegram such as sending messages, retrieving the message history,
|
|
handling updates, etc.
|
|
|
|
The ``TelegramClient`` inherits from several mixing ``Method`` classes,
|
|
since there are so many methods that having them in a single file would
|
|
make maintenance painful (it was three thousand lines before this separation
|
|
happened!). It's a "god object", but there is only a way to interact with
|
|
Telegram really.
|
|
|
|
The ``TelegramBaseClient`` is an ABC which will support all of these mixins
|
|
so they can work together nicely. It doesn't even know how to invoke things
|
|
because they need to be resolved with user information first (to work with
|
|
input entities comfortably).
|
|
|
|
The client makes use of the ``network/mtprotosender.py``. The
|
|
``MTProtoSender`` is responsible for connecting, reconnecting,
|
|
packing, unpacking, sending and receiving items from the network.
|
|
Basically, the low-level communication with Telegram, and handling
|
|
MTProto-related functions and types such as ``BadSalt``.
|
|
|
|
The sender makes use of a ``Connection`` class which knows the format in
|
|
which outgoing messages should be sent (how to encode their length and
|
|
their body, if they're further encrypted).
|
|
|
|
Auto-generated code
|
|
===================
|
|
|
|
The files under ``telethon_generator/`` are used to generate the code
|
|
that gets placed under ``telethon/tl/``. The parsers take in files in
|
|
a specific format (such as ``.tl`` for objects and ``.json`` for errors)
|
|
and spit out the generated classes which represent, as Python classes,
|
|
the request and types defined in the ``.tl`` file. It also constructs
|
|
an index so that they can be imported easily.
|
|
|
|
Custom documentation can also be generated to easily navigate through
|
|
the vast amount of items offered by the API.
