# Confy: compile-time configuration

Confy is a Rust compiler plugin for reading and using a TOML configuration file
at compile-time.

## Usage example

Add Confy to your `Cargo.toml`
```toml
[dependencies]
confy = "0.1.0"
```

And then you can use it like this:
```rust
#![feature(plugin)]
#![plugin(confy(file="Config.toml"))]

fn main() {
    assert_eq!(config!("string"), "value");
    assert_eq!(config!("int"), 42);
    assert_eq!(config!("bool"), false);
    assert_eq!(config!("float"), 78.8);
    assert_eq!(config!("array"), vec![3, 4, 5]);

    // You can specify a default, just in case
    assert_eq!(config!("key not found", "foo"), "foo");
}
```

You can retrieve all TOML types except for table: string, integers, floats, and
boolean values.
