[](https://travis-ci.org/seanmonstar/pretty-env-logger)
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.
## Usage
Add the dependency to your `Cargo.toml`:
```toml
[dependencies]
log = "0.4"
pretty_env_logger = "0.4"
```
Add some usage to your application:
```rust
extern crate pretty_env_logger;
#[macro_use] extern crate log;
fn main() {
pretty_env_logger::init();
info!("such information");
warn!("o_O");
error!("much error");
}
```
Then run your app with the environmental variable set:
```
RUST_LOG=trace cargo run
```
