Deltabot allows to implement and run chat bots for Delta Chat.

To install deltabot run the following command (preferably in a virtualenv):

$ pip3 install deltabot

Try typing "deltabot --version" to verify it worked.

Configure an e-mail address for your chat bot (using example credentials):

deltabot init tmp.vd9dd@testrun.org OzrSxdx5hiaD

Within a Delta Chat app (or another e-mail client), you may now send a chat /help message to tmp.vd9dd@testrun.org and should get a short list of available commands in the reply.

Checkout the deltabot repo to play with some example bots:

git clone https://github.com/deltachat/deltabot
cd deltabot

Now you can register an example bot and send/receive messages:

1. Register the example "mycalc bot":

   $ deltabot add-module example/mycalc.py
   

2. Now start serving the chat bot:

   $ deltabot serve
   

3. Within an Delta Chat app, you may now send a chat /help message to tmp.vd9dd@testrun.org and should get a short list of available commands in the reply. Send /mycalc 23+20-1 and wait for the the answer.

Note that the bot-answer speed largely depends on the provider you are using for the bot-email address. On test servers we get 3-5 seconds full roundtrips, between question and answer arriving back.

You can implement your plugin as a proper python package or wheel by using setuptools. Have a look in the examples/deltachat_echo example directory which contains a complete example.

Deltabot uses Autocrypt end-to-end encryption but note that the operator of the bot service can look into messages that are sent to it.
