possibility to modify source code to integer new function ?

[gandolfi974]

Hello, I am a beginner with llama.cpp. I'm sorry, because I'm going to ask you a question that may be silly.
Is it possible to modify the source code of llama.cpp to add functions to the chat.
I would like for example that at the beginning of a conversation the bot asks me for my email address and then saves it in a file or in its memory. It could then send me its answers by email.

thanks
