Colourful-Logger 2.0

The Colourful-Logger is a simple yet effective logging utility designed to enhance the readability of log messages by incorporating vibrant colors. Allowing you to also print structs, strings and other important types, either to the terminal or to a file.

Features

• Easy to use
• Colour coded log levels
• Quick identification of log types
• Enhanced readability
• Simple integration into projects
• Immediate visual improvement
• Terminal or File Logging
• Log any seralised data structures
• Log filtering

How to use

You can use either lazy_static! to use the logger as a global variable Colourful logger also has a built in default(), if you want a preset Logging.

[!IMPORTANT] If you want to log structs, which are typically not supported automatically Add serde = { version = "1.0.213", features = ["derive"] } to your Cargo.toml And then append #[derive(Serialize)] above your struct to seralise it.
It is then accessible to the logger as an object.

You may change the log file, remove the log file or even change the LogLevel at any time.

Change File and LogLevel

use colourful_logger::{Logger, LogLevel};

fn main() {
    let mut logger = Logger::default();

    logger.set_file("file_name.log");
    logger.remove_file();
    logger.set_log_level(LogLevel::Warn);
}

Without Default, but Lazy Static!

use colourful_logger::{Logger, LogLevel};
use lazy_static::lazy_static;
use serde::Serialize;

lazy_static! {
    // Keep log_file as "" so that it doesn't log to the file.
    // If you want it to then be sure to type in the file name and extension.
    static ref LOGGER: Logger = Logger::new(LogLevel::Info, Some(""));
}

#[derive(Serialize)]
struct RandomStruct {
    field1: String,
    field2: i32,
}

fn main(): {
    let random_struct = RandomStruct{ field1: "some random value 1".to_string(), field2: 540 };
    LOGGER.info("This is a message!", "Tag", false, random_struct);
    LOGGER.info("Another message!", "Main", true, "Joe".to_string());
    LOGGER.info_single("This is a single message!", "Hello");

    // Output
    // [2024-10-25 07:08:11] info: ┏ [Tag] This is a message!
    //                              ┗ [1] {"field1":"some random value 2","field2":69}
    //
    // [2024-10-25 07:08:11] info:  ┏ [Main] Another message!
    //                              ┃ at main.rs:42:5 [colourful_logger::main::h64e1f92e8d679d92]
    //                              ┗ [1] "Joe"
    //
    // [2024-10-25 07:08:11] info:  ▪ [Hello] This is a single message!
}

With Default, without Lazy Static!

use colourful_logger::Logger as Logger;

#[derive(Serialize)]
struct RandomStruct {
    field1: String,
    field2: i32,
}

fn main(): {
    let logger = Logger::default();

    logger.info("This is a message!", "Tag", false, random_struct);
    logger.info("Another message!", "Main", true, "Joe".to_string());
    logger.info_single("This is a single message!", "Hello");

    // Output
    // [2024-10-25 07:08:11] info: ┏ [Tag] This is a message!
    //                              ┗ [1] {"field1":"some random value 2","field2":69}
    //
    // [2024-10-25 07:08:11] info:  ┏ [Main] Another message!
    //                              ┃ at main.rs:42:5 [colourful_logger::main::h64e1f92e8d679d92]
    //                              ┗ [1] "Joe"
    //
    // [2024-10-25 07:08:11] info:  ▪ [Hello] This is a single message!
}
