Handsome Logger

Handsome logger aims to be fast, easy to use and configurable logger.

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 abilities of this library were insufficient for me and the changes that would have to be made to it to "fix" it were too big.

Example

Features

Multiple loggers - SimpleLogger(simplest and the stablest), TermLogger(SimpleLogger + colored output), WriteLogger(can save logs e.g. to file), CombinedLogger(can combine multiple loggers and save logs, both to file and to terminal)
Customizable format - each element, like timestamp or module name, log level, can be customized
Colored output - you can colorize any part of log message
Simple to use - library can be easily configured in few lines of code for most use cases
Ability to set log level by environment variable e.g. RUST_LOG=error ./app
Filtering messages - you can ignore any message basing on your own function
Multiple log message formatters(you can use them more than once - nobody can stop you): [_line] - prints line of code where log was called or 0 if cannot read line [_file] - prints full project path to file where log was called if is inside repository of full path if is outside, or "<unknown>" if cannot read file path [_file_name] - prints file name where log was called or "<unknown>" if cannot read file name [_module] - prints module name where log was called or "<unknown>" if cannot read module name [_msg] - prints user log message [_time] - prints time of logged message [_level] - prints log level (INFO, DEBUG, etc.) [_thread_id] - prints thread id [_thread_name] - prints thread name [_process_id] - prints process id [_color_start], [_color_end] - starts and ends colorization of log message
Example Usage

First add to Cargo.toml, this two lines handsome_logger = "0.3" log = "0.4" ```rust use handsome_logger::{ColorChoice, Config, TermLogger, TerminalMode}; use log::*;

fn main() { handsome_logger::init().unwrap(); // which is simpler alternative to // TermLogger::init(Config::default(), TerminalMode::Mixed, ColorChoice::Auto).unwrap();

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

} should print 21:20:22 [INFO] terminallogging: Got INFO 21:20:22 [WARN] terminallogging: Got WARNING 21:20:22 [ERROR] terminal_logging: Got ERROR ```

examples folder contains examples of - formatting logs - saving logs to file and rotating it - using multiple loggers - colouring terminal output - filtering messages
