sensible-env-logger 0.0.5

A simple logger, optionally configured via environment variables which writes to standard error with nice colored output for log levels. It sets up logging with "sensible" defaults that make it ideal for running examples and tests on a crate of choice.

Usage

Even though it has env in the name, the sensible-env-logger requires minimal configuration and setup to use:

#[macro_use] extern crate log;

fn main() {
sensible_env_logger::init!();

trace!("a trace example");
debug!("deboogging");
info!("such information");
warn!("o_O");
error!("boom");
}

Run the program and you should see all the log output for your crate.

Alternatively, run the program with the environment variables that control the log level for your crate as well as external crates explicitly set, like RUST_LOG=debug and GLOBAL_RUST_LOG=error.

Defaults

The defaults can be setup by calling init!() or try_init!() at the start of the program.

Examples

You can check out sample usage of this crate in the examples/ folder in the project repo on GitHub.

Readme Docs

You can find the crate's readme documentation on the crates.io page, or alternatively in the README.md file on the GitHub project repo.

Enable logging

This crate uses pretty_env_logger and env_logger internally, so the same ways of enabling logs through an environment variable are supported.

The sensible_env_logger crate re-exports these crates, through the pretty and env namespaces respectively.
