Python Bindings

All of the functions and methods are executed in the network loop of tg, NOT IMMEDIATELY. What this means is all calls should be considered async, and so there is an optional callback parameter for every function/method as the last parameter. For many uses, you won't care about the return value, so you can leave out the callback. Note there are a few cases where the callback is considered mandatory when the function is considered an information query and has no functionality without returned data. These will explicitly have the callback in the parameter list and will be noted in the description.

You can specify the python script from config ("python_script" option) or from command_line [-Z].

Version Notes

The python integration is written with Python 2/3 in mind, however, there is a bias to Python 3. Because of this, there are a few caveats:

  • I am only testing against Python 2.7, and have no intention to support/test < 2.7 but am more than happy to accept PRs for fixes as long as it does not break 2.7/3
  • repr/print of native types is dumbed down for < 2.7.9, I highly recommend using this version or newer. (This is due to a bug in python)

TGL Callbacks

Assign python fuctions to the following tgl attributes to set callbacks from TG.

Callback Description
tgl.on_binlog_replay_end() This is called when replay of old events end. Any updates prior this call were already received by this client some time ago.
tgl.on_get_difference_end() This is called after first get_difference call. So we received all updates after last client execute.
tgl.on_our_id(our_id) Informs about id of currently logged in user.
tgl.on_msg_receive(msg) This is called when we receive new tgl.Msg object (may be called before on_binlog_replay_end, than it is old msg).
tgl.on_user_update(peer, what_changed) updated info about user. peer is a tgl.Peer object representing the user, and what_changed is array of strings.
tgl.on_chat_update(peer, what_changed) updated info about chat. peer is a tgl.Peer object representing the chat, and what_changed is array of strings.
tgl.on_secret_chat_update(peer, what_changed) updated info about secret chat. peer is a tgl.Peer object representing the secret chat, and what_changed is array of strings.

Python Callback Signatures

As mentioned, all methods and functions have callbacks. The following are the different signatures that may be required (The description of the method will mention which is used)

Type Signature Description
empty_cb (success) This just indicated the success of the call. All other callback types have this as well.
contact_list_cb (success, peer_list) peer_list is a list of tgl.Peer objects
dialog_list_cb (success, dialog_list) dialog_list is a list of dicts, with keys: 'peer': tgl.Peer, 'message': tgl.Msg
msg_cb (success, msg) msg is a tgl.Msg
msg_list_cb (success, msg_list) msg_list is a list of tgl.Msg objects
file_cb (success, file_path) file_path is a string with an absolute path
chat_cb (success, peer) peer is a tgl.Peer that will have the type of tgl.PEER_CHAT
peer_cb (success, peer) peer is a tgl.Peer
secret_chat_cb (success, peer) peer is a tgl.Peer that will have the type of tgl.PEER_ENCR_CHAT
user_cb (success, peer) peer is a tgl.Peer that will have the type of tgl.PEER_USER
str_cb (success, string) string is a simple string

TGL Module Level Fuctions

All of these functions are accessed by importing the tgl module.

Function Description Callback Type
tgl.get_contact_list (callback) Retrieve peers stored in the contact list. requires callback contact_list_cb
tgl.get_dialog_list (callback) Get a list of current conversations with the tgl.Peer and the most recent tgl.Msg. requires callback dialog_list_cb
tgl.add_contact (phone, first_name, last_name) Adds contact to contact list, last name is optional contact_list_cb
tgl.del_contact (peer) Removes contact from contact list empty_cb
tgl.rename_contact (phone, first_name, last_name) Renaming a contact means sending the first/last name with the same phone number of an existing contact contact_list_cb
tgl.msg_global_search (text, callback) Get all messages that match the search text. requires callback msg_list_cb
tgl.set_profile_photo (file_path) Sets avatar to image found at file_path, no checking on the file. empty_cb
tgl.create_secret_chat (user) Creates secret chat with user, callback recommended to get new peer for the secret chat. secret_chat_cb
tgl.create_group_chat (peer_list, name) peer_list contains users to create group with, must be more than 1 peer. empty_cb
tgl.restore_msg (msg_id) Restore a deleted message by message id. empty_cb
tgl.status_online () Sets status as online empty_cb
tgl.status_offline () Sets status as offline empty_cb
tgl.import_chat_link (link) Join channel using the link. empty_cb
tgl.safe_exit (exit_status) Exception to the rule about callbacks, no callback parameter is accepted. Causes the bot to quit after cleaning up. exit_status is an optional parameter with the exit status (On glibc, this must be 0-255) NONE

Peer

Attributes

Attribute Type Description
id int Telegram peer id
type int Peer type, you can compare this with tgl.PEER_CHAT, tgl.PEER_USER, or tgl.PEER_ENCR_CHAT
type_name string Text representation of the type of the peer, 'chat', 'user', or 'secret_chat'
name string Returns the tg print version of the name. Usually FirstName_LastName for user, and the chatname with spaces replaced with _
user_id int Used in secret chats, since a secret chat has it's own id, this is the id of the user at the endpoint.
user_list peer_list Only used in tgl.PEER_CHAT peers, contains list of users. This currently does not work, it is not populating properly.
user_status dict Only used in tgl.PEER_USER peers. Dictionary with the current status, keys: 'online': bool, 'when': datetime
phone string Only used in tgl.PEER_USER peers. Phone number, only available if user is on contact list.
username string Only used in tgl.PEER_USER peers. Will be None if username is not set.
first_name string Only used in tgl.PEER_USER peers.
last_name string Only used in tgl.PEER_USER peers.
