On completion, it will automatically create the configuration file. Of course, you can also manually set the configuration file.

You can use .info to view the current configuration file path and roles file path.

You can use Environment Variables to customize certain configuration items.

Roles

We can let ChatGPT play a certain role through prompt to have it better generate what we want.

We can predefine a batch of roles in roles.yaml.

We can get the location of roles.yaml through the repl's .info command or cli's --info option.

For example, we can define a role:

- name: shell
  prompt: >
    I want you to act as a Linux shell expert.
    I want you to answer only with bash code.
    Do not provide explanations.    

Let ChatGPT answer questions in the role of a Linux shell expert.

〉.role shell

shell〉 extract encrypted zipfile app.zip to /tmp/app
mkdir /tmp/app
unzip -P PASSWORD app.zip -d /tmp/app

AIChat with roles will be a universal tool.

$ aichat --role shell extract encrypted zipfile app.zip to /tmp/app
unzip -P password app.zip -d /tmp/app

$ cat README.md | aichat --role spellcheck

For more details about roles, please visit Role Guide.

Chat REPL

aichat has a powerful Chat REPL.

The Chat REPL supports:

• Emacs keybinding
• Command autocompletion
• History search
• Fish-style history autosuggestion hints
• Edit/paste multiline input
• Undo support

Multi-line input

AIChat suppoprts bracketed paste, so you can paste multi-lines text directly.

AIChat also provides .edit command for multi-lines editing.

〉.edit convert json below to toml
{
  "an": [
    "arbitrarily",
    "nested"
  ],
  "data": "structure"
}

Submit the multi-line text with Ctrl+S.

.prompt - Set GPT prompt

When you set up a prompt, every message sent later will carry the prompt.

〉{ .prompt
I want you to translate the sentences I write into emojis.
I will write the sentence, and you will express it with emojis.
I just want you to express it with emojis.
I want you to reply only with emojis.
}
Done

Ｐ〉You are a genius
👉🧠💡👨‍🎓

Ｐ〉I'm embarrassed
🙈😳

.prompt actually creates a temporary role internally, so run .clear role to clear the prompt.

When you are satisfied with the prompt, add it to roles.yaml for later use.

.role - Let the AI play a role

Select a role:

〉.role emoji
name: emoji
prompt: I want you to translate the sentences I write into emojis. I will write the sentence, and you will express it with emojis. I just want you to express it with emojis. I don't want you to reply with anything but emoji. When I need to tell you something in English, I will do it by wrapping it in curly brackets like {like this}.
temperature: null

AI takes the role we specified:

emoji〉hello
👋

Clear current selected role:

emoji〉.clear role

〉hello
Hello there! How can I assist you today?

Session - context-aware conversation

By default, aichat behaves in a one-off request/response manner.

You should run aichat with -s/--session or use the .session command to start a session.

〉.session
temp）1 to 5, odd only                                                    4089
