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.
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 new. (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)

| 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 |
