# fondant
> an experimental, macro-only, boilerplate free, configuration management library
### example
```rust
// derive the `Configure` trait, and specify the
// `config_file` attribute
#[derive(Configure, Default, Serialize, Deserialize)]
#[config_file = "config.toml"]
struct AppConfig {
-- snip --
}
// `Configure` exposes `load` and `store`
fn main() {
let mut config = AppConfig::load().unwrap();
config.version = 2;
config.path = "/home/np".to_string();
config.store();
}
```
You can specify a path to be used, unless you want to stick
with the defaults:
```rust
// load from and store in user's home directory
#[config_file = "~/config.toml"]
```
`fondant` supports `yaml`, `toml` and `json`, defaults to
`toml`:
```rust
#[config_file = "config.toml"]
#[config_file = "my_app_config.yaml"]
#[config_file = "~/.app.conf.json"]
```
### todo
- [ ] improve error from trait impl
- [ ] use `syn::Error` and `syn::Result` to report macro errors
- [ ] write docs
- [ ] bundle and publish to crates.io
