Check out config.example.yaml for all configuration items.

There are some configurations that can be set through environment variables. Please see the Environment Variables for details.

Roles

We can define 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.

.role - let the AI play a role

Select a role:

〉.role emoji

Send message with the role:

emoji〉hello
👋

Leave current role:

emoji〉.exit role

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

Show role info:

emoji〉.info role
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

Temporarily use a role to send a message.

〉::: .role emoji
hello world

.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                                                                    0
1, 3, 5

temp）to 7                                                                        19(0.46%)
1, 3, 5, 7

temp）.exit session                                                               42(1.03%)
? Save session? (y/N)  

The prompt on the right side is about the current usage of tokens and the proportion of tokens used, compared to the maximum number of tokens allowed by the model.

.set - modify the configuration temporarily

〉.set temperature 1.2
〉.set dry_run true
〉.set highlight false
〉.set save false
〉.set auto_copy true
