Crate simple_file_logger

Simple File Logger

A simple file logger for rust.

The crate log is required to use this package.

cargo add log

Very basic setup, just provide an app name and an optional log level.

use simple_file_logger::{init_logger, LogLevel};
use log::info;

fn main() {
    init_logger("my_app", Loglevel::Info).unwrap();
    info!("Hello, world!");
}

or if you want to use the default log level (and save typing around 15 characters):

use simple_file_logger::init_logger;

fn main() {
    init_logger!("my_app").unwrap();
    info!("Hello, world!");
}

The log levels are: trace, debug, info , warn, error.

The log file is located:

OS	Path	Example
Windows	%FOLDERID_LocalAppData%\program_name\log\program_nametime_stamp.log	C:\Users\username\AppData\Local\program_name\log\program_name_2020-05-01T12-34-56.log
Linux	$XDG_DATA_HOME/program_name/log/program_name_time_stamp.log	/home/username/.local/share/program_name/log/program_name_2020-05-01T12-34-56.log
