A pretty, opinionated style for env_logger inspirated by pretty-env-logger.

It is not a goal of this crate to create a feature rich wrapper around env_logger. Instead it does provide a formater, which can be applied to the env_logger::Builder. Additional an optional function to create and register a zero config logger is provided.

Timestamp, emojis and modules can be disable separately.

Usage

Quickstart
my_env_logger_style::just_log();
info!("Hello, world!");

This creates the default env_logger from environment variables and register it as logger.

Advance

You can also create an env_logger::Builder and apply the style definded at this crate, by using the format() function.

use log::info;
use my_env_logger_style::format;

env_logger::Builder::new()
	.parse_default_env()
	.format(format)
	.init();
info!("Hello, world!");

Feature-flags

time (default)

Enable RFC3339 timestamps
