## Config

On first launch, aichat will guide you through configuration.

```
> No config file, create a new one? Yes
> Openai API Key: sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
> Use proxy? Yes
> Set proxy: socks5://127.0.0.1:1080
> Save chat messages Yes
```

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

```yaml
api_key: "<YOUR SECRET API KEY>"  # Request via https://platform.openai.com/account/api-keys
temperature: 1.0                  # optional, see https://platform.openai.com/docs/api-reference/chat/create#chat/create-temperature
save: true                        # optional, If set to true, aichat will save chat messages to message.md
highlight: true                   # optional, Set false to turn highlight
proxy: "socks5://127.0.0.1:1080"  # optional, set proxy server. e.g. http://127.0.0.1:8080 or socks5://127.0.0.1:1080
```

> You can specify the configuration directory through `$AICHAT_CONFIG_DIR`

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

### Roles

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

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

For example, we 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 write explanations.
  # temperature: 0.3
```

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

```
〉.role shell

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

Chat REPL also provide many commands.

### `.info` - view current configuration information.

```
〉.info
config_file         /home/alice/.config/aichat/config.yaml
roles_file          /home/alice/.config/aichat/roles.yaml
messages_file       /home/alice/.config/aichat/messages.md
role                -
api_key             sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
temperature         -
save                true
highlight           true
proxy               -
dry_run             false
```

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

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

### `.prompt` - use 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 wrote into emojis.
:::     I will write the sentence, and you will express it with emojis.
:::     I don't want you to reply with anything but emoji.
::: }
Done

〉You are a genius
👉🧠💡👨‍🎓

〉I'm embarrassed
🙈😳
```

`.prompt` actually creates a temporary role called `%TEMP%` 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 shell
```

Unselect a role.
```
〉.clear role
```

Use `.info` to check current selected role.

### `.editor` - input/paste multiline text

Type `.editor {` to enter editor mode, you can input/paste multiline text, quite editor mode with `}`

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