A simple logger built on top of [env_logger](https://docs.rs/env_logger).

It is configured via an environment variable and writes to standard

error with nice colored output for log levels.

Originally a fork from [pretty_env_logger](https://github.com/seanmonstar/pretty-env-logger).

## Screenshots

## Usage

Add the dependency to your `Cargo.toml`:

```toml

[dependencies]

log = "0.4"

lovely_env_logger = "0.6"

```

Add some usage to your application:

```rust

extern crate lovely_env_logger;

#[macro_use] extern crate log;

fn main() {

    lovely_env_logger::init_default();

    info!("such information");

    warn!("o_O");

    error!("much error");

}

```

Then run your app with the environmental variable set:

```

RUST_LOG=trace cargo run

```
