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

```yaml

```

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

> You can use [Environment Variables](https://github.com/sigoden/aichat/wiki/Environment-Variables) to customize certain configuration items.

### 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:

```yaml
- 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](https://github.com/sigoden/aichat/wiki/Role-Guide).

## Chat REPL

aichat has a powerful Chat REPL.

The Chat REPL supports:

- Emacs/Vi keybinding
- Command autocompletion
- Edit/paste multiline input
- Undo support

### `.help` - print help message

wrap_code           false
dry_run             false
keybindings         emacs
```

### `.edit` -  multiline editing

AIChat supports 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 with `Ctrl+S`.


### `.model` - choose a model

```
> .model openai:gpt-4
> .model localai:gpt4all-j
```

> You can easily enter enter model name using autocomplete.

### `.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〉.exit 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
1, 3, 5

temp）to 7                                                                                4070
1, 3, 5, 7

temp）.exit session

〉
```


### `.set` - modify the configuration temporarily

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