📦 MyLog

A minimal Rust crate providing 3 lightweight logging macros to simplify writing log messages to a file.

✨ Features

This crate includes the following macros:

• info!()
• warn!()
• error!()

Each macro:

• Parses input like format!()

• Automatically adds :

  • A timestamp
  • Log level (INFO, WARN, ERROR)
  • Source file name and line number

• Writes the formatted message to a log.txt file

[!NOTE] You can easily set the folder where the log file is saved with the function init().

🚀 Getting Started

🔧​ Install

To start using this crate in your Rust project, you can choose one of the following integration methods :

• Add the crate as a dependency by editing your Cargo.toml :

[dependencies]
mylog = "0.1.2"

• Use cargo add :

cargo add mylog

📚​ Examples

You could clone the repository to test the following example :

git clone https://github.com/LugolBis/mylog

cd mylog && cargo run examples

A simple example :

// A Rust script

use mylog::{error, info, warn, logs::init};

fn main() {
    // To save the log file in the folder 'path/to/my_logs'
    init("path/to/mylogs".to_string());

    info!("Welcome on MyLog !");
    warn!("Driving too fast is dangerous -> {:#?}", ["car0", "car1"]);
    error!("{} NOT FOUND - We can't find your dignity...", 404);
}

This will write the following content in a file logs.txt at the root of your project :

[2025-06-04 23:35:06] [INFO] [examples/usage/src/main.rs:4] : Welcome on MyLog !
[2025-06-04 23:35:06] [WARNING] [examples/usage/src/main.rs:5] : Driving too fast is dangerous -> [
    "car0",
    "car1",
]
[2025-06-04 23:35:06] [ERROR] [examples/usage/src/main.rs:6] : 404 NOT FOUND - We can't find your dignity...

[!NOTE] For performancies prefer the version 1.0.0, who's provide less fonctionnalities.
