Handsome Logger

Handsome logger aims to be quite simple and quite powerful.

This is a fork of simplelog.rs from commit 70f4dcb6c20de819b68a4c52988e850403f779db and is available under same license as the original project.

I created it because the formatting possibilities of this library were insufficient for me and the changes that would have to be made to it to "fix" it were too big.

Features

Colored output - at least colored is [INFO], [DEBUG], [WARN], [TRACE] and [ERROR]
Saving both to file and terminal
Customizable format - place where each field is added can be easily modified
Multiple properties - thread id, module name, file name, line number, timestamp

Example Usage

First add to Cargo.toml, this two lines

handsome_logger = "0.1"
log = "0.4"

use handsome_logger::{ColorChoice, CombinedLogger, ConfigBuilder, TermLogger};
use log::{error, info,debug, trace, warn};

fn main() {
    let config = ConfigBuilder::default().set_level(handsome_logger::LevelFilter::Debug).build();

    TermLogger::init(
        config,
        handsome_logger::TerminalMode::Mixed, // Save results to stderr or stdout?
        ColorChoice::Auto,
    ).unwrap();

    trace!("Got TRACE");
    debug!("Got DEBUG");
    info!("Got INFO");
    warn!("Got WARNING");
    error!("Got ERROR");
}

should print

17:38:18 [DEBUG] [project:14] Got DEBUG
17:38:18 [INFO] [project:15] Got INFO
17:38:18 [WARN] [project:16] Got WARNING
17:38:18 [ERROR] [project:17] Got ERROR

Why?

Recently I needed to use logger in my project, but I found that tested loggers not have all required features that I need:

Formatting is simple - both env_logger and simplelog are simple to use, but for users may be a little hard to modify
Save data in different format to file and to terminal
Have colourful output - without it is hard to read logs

TODO

Add more tests
Set minimal required version of rust(currently only latest rust version is supported)
Add more documentations
Add more examples
Add handling of default environment variables like env_logger
Add filtering options
