Crate selog

Simple, Easy LOGger logs to StdErr.

CAUTION: This crate is compatible with log ^0.4.11.

This crate provides a simple, minimal and easy to use implementation of log crate.

Example

Simple Use Case

#[macro_use]
extern crate log;
extern crate selog;

use selog::SELog;

fn main() {
    SELog::new().init().unwrap();

    error!("Failed something");

    // ..
}

Using clap

Tested on clap 2.33.3

#[macro_use]
extern crate log;
#[macro_use]
extern crate clap;
extern crate selog;

use clap::Arg;
use selog::{Colorize, SELevel, SELog};
use std::str::FromStr;

fn main() {
    let m = app_from_crate!()
        .args(&[
            Arg::from_usage("-v --verbose 'More verbose output.'"),
            Arg::from_usage("-d --debug 'Output debug log.'"),
            Arg::from_usage("-q --quiet 'Less output.'"),
            Arg::from_usage("--no-output 'Silence all output.'"),
            Arg::from_usage("--color=[mode] 'Control color of output.'")
                .possible_values(&["off", "auto", "on"])
                .default_value("auto"),
        ])
        .get_matches();

    SELog::new()
        .level(
            SELevel::new()
                .verbose(m.is_present("verbose"))
                .debug(m.is_present("debug"))
                .quiet(m.is_present("quiet"))
                .off(m.is_present("no-output")),
        )
        // As the string is validated in the definition, these `unwrap` are safe.
        .colorize(Colorize::from_str(m.value_of("color").unwrap()).unwrap())
        .init()
        .unwrap();


    error!("Failed something.");

    // ...
}
