# milla

Milla is an IRC bot that sends things over to an LLM when you ask it questions and prints the answer with optional syntax-highlighting.<br/>
Milla can run more than one instance of itself, use different proxies(socks5 and http), connect to more than one IRC networks and log to different databases.<br/>
Currently supported providers:

- Ollama
- Openai
- Gemini

![milla](./milla.png)

milla accepts one cli arg which tells it where to look for the config file:<br/>

```$ milla -help
Usage of ./milla:
  -config string
          path to the config file (default "./config.toml")
```

The bot will respond to chat prompts if they begin with `botnick:`.<br/>
The bot will see a chat prompt as a command if the message begins with `botnick: /`.<br/>

## Config

An example is provided under `config-example.toml`. Please note that all the config options are specific to one instance which is defined by `ircd.nameofyourinstance`.<br/>

#### ircServer

The address for the IRC server to connect to.

#### ircNick

The nick the bot should use.

#### enableSasl

Whether to use SASL for authentication.

#### ircSaslUser

#### ollamaEndpoint

The address for the Ollama chat endpoint.

#### model

The name of the model to use.

#### chromaStyle

The style to use for syntax highlighting done by [chroma](https://github.com/alecthomas/chroma). This is basically what's called a "theme".

#### chromaFormatter

The formatter to use. This tells chroma how to generate the color in the output. The supported options are:

- `noop` for no syntax highlighting
- `terminal` for 8-color terminals
- `terminal8` for 8-color terminals
- `terminal16` for 16-color terminals
- `terminal256` for 256-color terminals
- `terminal16m` for treucolor terminals
- `html` for HTML output

**_NOTE_**: please note that the terminal formatters will increase the size of the IRC event. Depending on the IRC server, this may or may not be a problem.

#### provider

Which LLM provider to use. The supported options are:

- [ollama](https://github.com/ollama/ollama)
- chatgpt
- gemini

#### apikey

#### pingDelay

Ping delay for the IRC server.

#### pingTimeout

#### useTLS

Whether to use TLS to connect to the IRC server. This option is provided to support usage on overlay networks such as Tor, i2p and [yggdrassil](https://github.com/yggdrasil-network/yggdrasil-go).

#### disableSTSFallback

Disables the "fallback" to a non-TLS connection if the strict transport policy expires and the first attempt to reconnect back to the TLS version fails.

#### allowFlood

#### debug

Whether to enable debug logging. The logs are written to stdout.

#### out

```
admins = ["admin1", "admin2"]
```

```

### databaseUser

### databasePassword

```

### llmProxy

Determines which proxy to use to connect to the LLM endpoint:

```
llmProxy = "socks5://127.0.0.1:9050"
```

### ircdName

Name of the milla instance, must be unique across all instances.

### adminOnly

## Deploy

### Docker

Images are automatically pushed to dockerhub. So you can get it from [there](https://hub.docker.com/r/terminaldweller/milla).
An example docker compose file is provided in the repo under `docker-compose.yaml`.
milla can be used with [gvisor](https://gvisor.dev/)'s docker runtime, `runsc`.

```yaml
services:
  milla:
    image: milla
    build:
      context: .
    deploy:
      resources:
        limits:
          memory: 64M
    logging:
      driver: "json-file"
      options:
        max-size: "100m"
    networks:
      - millanet
      user: ${UID}:${GID}
    restart: unless-stopped
    command: ["--config", "/opt/milla/config.toml"]
    volumes:
      - ./config-gpt.toml:/opt/milla/config.toml
      - /etc/localtime:/etc/localtime:ro
      - /etc/resolv.conf:/etc/resolv.conf:ro
    cap_drop:
      - ALL
    runtime: runsc
networks:
  millanet:
    driver: bridge
```

### Public Message Storage

milla can be configured to store all incoming public messages for future use in a postgres database. An example docker compose file is provided under `docker-compose-postgres.yaml`.<br/>

The env vars `UID`and `GID`need to be defined or they can replaces by your host user's uid and gid.<br/>

As a convenience, there is a a [distroless](https://github.com/GoogleContainerTools/distroless) dockerfile, `Dockerfile_distroless` also provided.<br/>
A vendored build of milla is available by first running `go mod vendor` and then using the provided Dockerfile, `Dockerfile_distroless_vendored`.<br/>

### Build

For a regular build:

```sh
go mod download
go build
```

For a vendored build:
