Coding style
============
Knowledge of Python is a obviously a must to develop a Python library.
A good online resource is `Dive Into Python 3 <http://www.diveintopython3.net/>`_.
Telethon uses multiple tools to automatically format the code and check for linting rules.
This means you can simply ignore formatting and let the tools handle it for you.
You can find these tools under the ``tools/`` folder.
The documentation is written with mostly a newline after every period.
This is not a hard rule.
Lines can be cut earlier if they become too long to be comfortable.
Commit messages should be short and descriptive.
They should start with an action in the present ("Fix" and not "Fixed").
This saves a few characters and represents what the commit will "do" after applied.

Project Structure
=================
Contributing
============
Telethon welcomes all new contributions, whether it's reporting bugs or sending code patches.
Please keep both the philosophy and coding style below in mind.
Be mindful when adding new features.
Every new feature must be understood by the maintainer, or otherwise it will probably rot.
The *usefulness : maintenance-cost* ratio must be high enough to warrant being built-in.
Consider whether your new features could be a separate add-on project entirely.
Philosophy
----------
* Dependencies should only be added when absolutely necessary.
* Dependencies written in anything other than Python cannot be mandatory.
* The library must work correctly with no system dependencies other than Python 3.
* Strict type-checking is required to pass everywhere in the library to make upgrades easier.
* The code structure must make use of hard and clear boundaries to keep the different parts decoupled.
* The API should cover only the most commonly used features to avoid bloat and reduce maintenance costs.
* Documentation must be a pleasure to use and contain plenty of code examples.

TelegramClient renamed to Client
--------------------------------
You can rename it with :keyword:`as` during import if you want to use the old name.
Python allows using namespaces via packages and modules.
Therefore, the full name :class:`telethon.Client` already indicates it's from ``telethon``, so the old ``Telegram`` prefix was redundant.
No telethon.sync hack

You can no longer ``import telethon.sync`` to have most calls wrapped in :meth:`asyncio.loop.run_until_complete` for you.
Raw API is now private
----------------------
@ -140,6 +155,27 @@ Functions no longer have an asynchronous ``.resolve()``.
This used to let you pass usernames and have them be resolved to :tl:`InputPeer` automatically (unless it was nested).
Changes to start and client context-manager
-------------------------------------------
You can no longer ``start()`` the client.
Instead, you will need to first :meth:`~Client.connect` and then start the :meth:`~Client.interactive_login`.
In v1, the when using the client as a context-manager, ``start()`` was called.
Since that method no longer exists, it now instead only :meth:`~Client.connect` and :meth:`~Client.disconnect`.
This means you won't get annoying prompts in your terminal if the session was not authorized.
It also means you can now use the context manager even with custom login flows.
The old ``sign_in()`` method also sent the code, which was rather confusing.
Instead, you must now :meth:`~Client.request_login_code` as a separate operation.
The old ``log_out()`` was also renamed to :meth:`~Client.sign_out` for consistency with :meth:`~Client.sign_in`.
The old ``is_user_authorized()`` was renamed to :meth:`~Client.is_authorized` since it works for bot accounts too.

See the documentation of :meth:`~telethon.types.File.new` to learn what they do.
If you wrote to an in-memory file, you probably want to ``file.seek(0)`` first.
If you want to send :class:`bytes`, wrap them in :class:`io.BytesIO` first.
See the section on :doc:`/concepts/messages` to learn about message formatting.
You can also pass any :class:`~telethon.types.File` that was previously sent in Telegram to send a copy.
This will not download and re-upload the file, but will instead reuse the original without forwarding it.
Note that only one *caption* parameter can be provided.
Last, a URL can also be specified.
For the library to detect it as a URL, the string *must* start with either ``http://` or ``https://``.
Telethon will *not* download and upload the file, but will instead pass the URL to Telegram.
If Telegram is unable to access the media, is too large, or is invalid, the method will fail.
When using URLs, it is recommended to explicitly pass either a name or define the mime-type.
To make sure the URL is interpreted as an image, use `send_photo`.
:param size:
The size of the local file to send.
This parameter **must** be specified when sending a previously-opened or in-memory files.
The library will not ``seek`` the file to attempt to determine the size.
This can be less than the real file size, in which case only ``size`` bytes will be sent.
This can be useful if you have a single buffer with multiple files.
:param name:
Override for the default file name.
When given a string or path, the :attr:`pathlib.Path.name` will be used by default only if this parameter is omitted.
This parameter **must** be specified when sending a previously-opened or in-memory files.
The library will not attempt to read any ``name`` attributes the object may have.
:param mime_type:
Override for the default mime-type.
By default, the library will use :func:`mimetypes.guess_type` on the name.
If no mime-type is registered for the name's extension, ``application/octet-stream`` will be used.
:param compress:
Whether the image file is allowed to be compressed by Telegram.
If not, image files will be sent as document.
:param animated:
Whether the sticker is animated (not a static image).
:param duration:
Duration, in seconds, of the audio or video.
This field should be specified when sending audios or videos from local files.
The floating-point value will be rounded to an integer.
:param voice:
Whether the audio is a live recording, often recorded right before sending it.
:param title:
Title of the song in the audio file.
:param performer:
Artist or main performer of the song in the audio file.
:param emoji:
Alternative text for the sticker.
:param width:
Width, in pixels, of the image or video.
This field should be specified when sending images or videos from local files.
:param height:
Height, in pixels, of the image or video.
This field should be specified when sending images or videos from local files.
:param round:
Whether the video should be displayed as a round video.
:param supports_streaming:
Whether clients are allowed to stream the video having to wait for a full download.
Note that the file format of the video must have streaming support.
:param muted:
Whether the sound of the video is or should be missing.
This is often used for short animations or "GIFs".
:param caption: See :ref:`formatting`.
:param caption_markdown: See :ref:`formatting`.
:param caption_html: See :ref:`formatting`.
