Then start editing the commands.

Usage

To send messages use the send_message function:

send_message "$TARGET" "lol" 

To send images use the send_photo function:

send_photo "$TARGET" "/home/user/doge.jpg"  

To send custom keyboards use the send_keyboard function or the send_message function:

send_keyboard "$TARGET" "Text that will appear in chat?" "Yep" "No"

To create interactive chats, write (or edit the question script) a normal bash (or C or python) script, chmod +x it and then substitute ./question @ line 49 with the command you usually use to start the script.
The text that the script will output will be sent in real time to the user, and all user input will be sent to the script (as long as it's running or until the user kills it with /cancel).
To open up a keyboard in an interactive script, print out the keyboard layout in the following way:

echo "Text that will appear in chat? mykeyboardstartshere Yep No"

Same goes for images:

echo "Text that will appear in chat? myimagelocationstartshere /home/user/doge.jpg"

Or both:

echo "Text that will appear in chat? mykeyboardstartshere Yep No myimagelocationstartshere /home/user/doge.jpg"

Once you're done editing start the bot with tmux new-session -d -s bashbot "./bashbot.sh".
To stop the bot run tmux kill-session -t bashbot.
If some thing doesn't work as it should, debug with bash -x bashbot.sh.

That's it!
