# Telethon
|
|
||||||
**Telethon** is Telegram client implementation in Python which uses the latest available API of Telegram.
|
|
||||||
The project's **core only** is based on TLSharp, a C# Telegram client implementation.

## Why Telethon?
|
|
||||||
> Why should I bother with Telethon? There are more mature projects already, such as
|
|
||||||
> [telegram-cli](https://github.com/vysheng/tg) with even (limited) Python support. And we have the
|
|
||||||
> [official](https://github.com/telegramdesktop/tdesktop) [clients](https://github.com/DrKLO/Telegram)!
|
|
||||||
|
|
||||||
With Telethon you don't really need to know anything before using it. Create a client with your settings.
|
|
||||||
Connect. You're ready to go.
|
|
||||||
|
|
||||||
Being written **entirely** on Python, Telethon can run as a script under any environment you wish, (yes,
|
|
||||||
[Android too](https://f-droid.org/repository/browse/?fdfilter=termux&fdid=com.termux)). You can schedule it,
|
|
||||||
or use it in any other script you have. Want to send a message to someone when you're available? Write a script.
|
|
||||||
Do you want check for new messages at a given time and find relevant ones? Write a script.
|
|
||||||
|
|
||||||
Hungry for more API calls which the `TelegramClient` class doesn't _seem_ to have implemented?
|
|
||||||
Please read [this section](#using-more-than-just-telegramclient).
|
|
||||||
|
|
||||||
## Obtaining your Telegram `API ID` and `Hash`
|
|
||||||
In order to use Telethon, you first need to obtain your very own API ID and Hash:
|
|
||||||
1. Follow [this link](https://my.telegram.org) and login with your phone number.
|
|
||||||
2. Click under `API Development tools`.
|
|
||||||
3. A `Create new application` window will appear. Fill in your application details.
|
|
||||||
There is no need to enter any `URL`, and only the first two fields (`App title` and `Short name`)
|
|
||||||
can be changed later as long as I'm aware.
|
|
||||||
4. Click on `Create application` at the end.
|
|
||||||
|
|
||||||
Now that you know your `API ID` and `Hash`, you can continue installing Telethon.
|
|
||||||
|
|
||||||
## Installing Telethon
|
|
||||||
### Installing Telethon via `pip`
|
|
||||||
On a terminal, issue the following command:
|
|
||||||
```sh
|
|
||||||
sudo -H pip install telethon
|
|
||||||
```
|
|
||||||
|
|
||||||
You're ready to go.
|
|
||||||
|
|
||||||
### Installing Telethon manually
|
|
||||||
1. Install the required `pyaes` module: `sudo -H pip install pyaes`
|
|
||||||
([GitHub](https://github.com/ricmoo/pyaes), [package index](https://pypi.python.org/pypi/pyaes))
|
|
||||||
2. Clone Telethon's GitHub repository: `git clone https://github.com/LonamiWebs/Telethon.git`
|
|
||||||
3. Enter the cloned repository: `cd Telethon`
|
|
||||||
4. Run the code generator: `python3 telethon_generator/tl_generator.py`
|
|
||||||
5. Done!
|
|
||||||
|
|
||||||
## Running Telethon
|
|
||||||
If you've installed Telethon via pip, launch an interactive python3 session and enter the following:
|
|
||||||
```python
|
|
||||||
>>> from telethon import InteractiveTelegramClient
|
|
||||||
>>> # 'sessionid' can be 'yourname'. It'll be saved as yourname.session
|
|
||||||
>>> # Also (obviously) replace the api_id and api_hash with your values
|
|
||||||
...
|
|
||||||
>>> client = InteractiveTelegramClient('sessionid', '+34600000000',
|
|
||||||
... api_id=12345, api_hash='0123456789abcdef0123456789abcdef')
|
|
||||||
|
|
||||||
┌───────────────────────────────────────────────────────────┐
|
|
||||||
│ Initialization │
|
|
||||||
└───────────────────────────────────────────────────────────┘
|
|
||||||
Initializing interactive example...
|
|
||||||
Connecting to Telegram servers...
|
|
||||||
>>> client.run()
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
If, on the other hand, you've installed Telethon manually, head to the `api/` directory and create a
|
|
||||||
copy of the `settings_example` file, naming it `settings` (lowercase!). Then fill the file with the
|
|
||||||
corresponding values (your `api_id`, `api_hash` and phone number in international format).
|
|
||||||
|
|
||||||
Then, simply run `python3 try_telethon.py` to start the interactive example.
|
|
||||||
|
|
||||||
## Advanced uses
|
|
||||||
### Using more than just `TelegramClient`
|
|
||||||
The `TelegramClient` class should be used to provide a quick, well-documented and simplified starting point.
|
|
||||||
It is **not** meant to be a place for _all_ the available Telegram `Request`'s, because there are simply too many.
|
|
||||||
|
|
||||||
However, this doesn't mean that you cannot `invoke` all the power of Telegram's API. Whenever you need to `invoke`
|
|
||||||
a Telegram `Request`, all you need to do is the following:
|
|
||||||
```python
|
|
||||||
result = client.invoke(SomeRequest(...))
|
|
||||||
```
|
|
||||||
|
|
||||||
You have just `invoke`'d `SomeRequest` and retrieved its `result`! That wasn't hard at all, was it? Now you may wonder,
|
|
||||||
what's the deal with _all the power of Telegram's API_? Have a look under `tl/functions/`.
|
|
||||||
That is _everything_ you can do. You have **over 200 API `Request`'s** at your disposal.
|
|
||||||
|
|
||||||
However, we don't pretty know _how_ that `result` looks like. Easy. `print(str(result))` should give you a quick overview.
|
|
||||||
Nevertheless, there may be more than a single `result`! Let's have a look at this seemingly innocent `TL` definition:
|
|
||||||
|
|
||||||
`messages.getWebPagePreview#25223e24 message:string = MessageMedia;`
|
|
||||||
|
|
||||||
Focusing on the end, we can see that the `result` of invoking `GetWebPagePreviewRequest` is `MessageMedia`. But how
|
|
||||||
can `MessageMedia` exactly look like? It's time to have another look, but this time under `tl/types/`:
|
|
||||||
```sh
|
|
||||||
$ tree -P "message_media_*"
|
|
||||||
.
|
|
||||||
├── tl
|
|
||||||
│ └── types
|
|
||||||
│ ├── message_media_contact.py
|
|
||||||
│ ├── message_media_document.py
|
|
||||||
│ ├── message_media_empty.py
|
|
||||||
│ ├── message_media_geo.py
|
|
||||||
│ ├── message_media_photo.py
|
|
||||||
│ ├── message_media_unsupported.py
|
|
||||||
│ ├── message_media_venue.py
|
|
||||||
│ └── message_media_web_page.py
|
|
||||||
```
|
|
||||||
Those are _eight_ different types! How do we know what exact type it is to determine its properties? A simple
|
|
||||||
`if type(result) == MessageMediaContact:` or similar will do. Now you're ready to take advantage of Telegram's polymorphism.
|
|
||||||
|
|
||||||
### Tips for porting Telethon
|
|
||||||
First of all, you need to understand how the `scheme.tl` (`TL` language) works. Every object definition is written as follows:
|
|
||||||
|
|
||||||
`name#id argument_name:argument_type = CommonType`
|
|
||||||
|
|
||||||
This means that in a single line you know what the `TLObject` name is. You know it's unique ID,
|
|
||||||
and you know what arguments it has. It really isn't that hard to write a generator for generating code to any platform!
|
|
||||||
|
|
||||||
The generated code should also be able to _encode_ the `Request` into bytes, so they can be sent over the network.
|
|
||||||
This isn't a big deal either, because you know how the `TLObject`'s are made.
|
|
||||||
|
|
||||||
Once you have your own [code generator](telethon_generator/tl_generator.py), start by looking at the
|
|
||||||
[first release](https://github.com/LonamiWebs/Telethon/releases/tag/v0.1) of Telethon.
|
|
||||||
The code there is simple to understand, easy to read and hence easy to port. No extra useless features.
|
|
||||||
Only the bare bones. Perfect for starting a _new implementation_.
|
|
||||||
|
|
||||||
P.S.: I may have lied a bit. The `TL` language is not that easy. But it's not that hard either.
|
|
||||||
You're free to sniff the `parser/` files and learn how to parse other more complex lines.
|
|
||||||
Or simply use that code and change the [SourceBuilder](telethon_generator/parser/source_builder.py)!
|
|
||||||
|
|
||||||
### Code generator limitations
|
|
||||||
The current code generator is not complete, yet adding the missing features would only over-complicate an already hard-to-read code.
|
|
||||||
Some parts of the `.tl` file _should_ be omitted, because they're "built-in" in the generated code (such as writing booleans, etc.).
|
|
||||||
|
|
||||||
In order to make sure that all the generated files will work, please make sure to **always** comment out these lines in `scheme.tl`
|
|
||||||
(the latest version can always be found
|
|
||||||
[here](https://github.com/telegramdesktop/tdesktop/blob/master/Telegram/SourceFiles/mtproto/scheme.tl)):
|
|
||||||
|
|
||||||
```tl
|
|
||||||
// boolFalse#bc799737 = Bool;
|
|
||||||
// boolTrue#997275b5 = Bool;
|
|
||||||
// true#3fedd339 = True;
|
|
||||||
// vector#1cb5c415 {t:Type} # [ t ] = Vector t;
|
|
||||||
```
|
|
||||||
|
|
||||||
Also please make sure to rename `updates#74ae4240 ...` to `updates_tg#74ae4240 ...` or similar to avoid confusion between
|
|
||||||
the `updates` folder and the `updates.py` file! Note that depending on the name, it may break things somewhere else. So
|
|
||||||
please stick with the suggested name or give one which is still descriptive enough and easy to remember.
|
|
||||||
|
|
||||||
### Updating the `scheme.tl`
|
|
||||||
Have you found a more updated version of the `scheme.tl` file? Those are great news! Updating is as simple as grabbing the
|
|
||||||
[latest version](https://github.com/telegramdesktop/tdesktop/blob/master/Telegram/SourceFiles/mtproto/scheme.tl) and
|
|
||||||
replacing the one you can find in this same directory by the updated one. Don't forget to run `python3 tl_generator.py`.
|
|
||||||
|
|
||||||
If the changes weren't too big, everything should still work the same way as it did before; but with extra features.

You're free to sniff the :code:`parser/` files and learn how to parse other more complex lines.
|
||||||
|
Or simply use that code and change the [SourceBuilder](telethon_generator/parser/source_builder.py)!
|
||||||
|

||||||
|
Code generator limitations
|
||||||
|
--------------------------
|
||||||
|
The current code generator is not complete, yet adding the missing features would only over-complicate an
|
||||||
|
already hard-to-read code. Some parts of the :code:`.tl` file *should* be omitted, because they're "built-in"
|
||||||
|
in the generated code (such as writing booleans, etc.).
|
||||||
|
|
||||||
|
In order to make sure that all the generated files will work, please make sure to **always** comment out these
|
||||||
|
lines in :code:`scheme.tl` (the latest version can always be found
|
||||||
|
`here <https://github.com/telegramdesktop/tdesktop/blob/master/Telegram/SourceFiles/mtproto/scheme.tl>`_):
|
||||||
|
|
||||||
|
.. code:: c
|
||||||
|
|
||||||
|
// boolFalse#bc799737 = Bool;
|
||||||
|
// boolTrue#997275b5 = Bool;
|
||||||
|
// true#3fedd339 = True;
|
||||||
|
// vector#1cb5c415 {t:Type} # [ t ] = Vector t;
|
||||||
|
|
||||||
|
Also please make sure to rename :code:`updates#74ae4240 ...` to :code:`updates_tg#74ae4240 ...` or similar to
|
||||||
|
avoid confusion between the :code:`updates` folder and the :code:`updates.py` file! Note that depending on the name,
|
||||||
|
it may break things somewhere else. So please stick with the suggested name or give one which is still descriptive
|
||||||
|
enough and easy to remember.
|
||||||
|
|
||||||
|
Updating the :code:`scheme.tl`
|
||||||
|
------------------------------
|
||||||
|
Have you found a more updated version of the :code:`scheme.tl` file? Those are great news! Updating is as simple
|
||||||
|
as grabbing the
|
||||||
|
`latest version <https://github.com/telegramdesktop/tdesktop/blob/master/Telegram/SourceFiles/mtproto/scheme.tl>`_
|
||||||
|
and replacing the one you can find in this same directory by the updated one.
|
||||||
|
Don't forget to run :code:`python3 tl_generator.py`.
|
||||||
|
|
||||||
|
If the changes weren't too big, everything should still work the same way as it did before; but with extra features.
