# Otter

Otter is a modern implementation of the [Gpodder server](https://gpodder.net/)
API. Its primary goal is to be used as a self-hostable drop-in replacement for
Gpodder, suitable for low-power devices.

## Features

* Implementation of API sections needed for synchronisation
    * Authentication
    * Devices API
    * Subscriptions API
    * Episode actions API

## Configuration

Otter is configurable via a TOML config file, environment variables and CLI
arguments thanks to the [Figment](https://docs.rs/figment/latest/figment/)
library. Each variable in the configuration file below can be provided via an
environment variable (prefixed using `OTTER_`) or a CLI argument.

```toml
data_dir = "./data"
domain = "127.0.0.1"
port = 8080
```

Otter can be told to read a config variable using the `--config/-c` flag (see
the `help` command for other useful CLI commands). Each variable needs to be
provided either from the config file, as an environment variable (e.g.
`OTTER_DATA_DIR`) or a CLI argument (e.g. `--data-dir`).

If a variable is provided in multiple ways, environment variables overwrite
configuration file variables, and CLI arguments overwrite both.
