Rust logging ⛔

💬 A couple of functions to make logging in Rust easier.

Installation 📦

```toml

Cargo.toml

[dependencies] rust_logging = "1.0.0" ```

Usage 📝

Initializing

```rs use rust_logging::*;

fn main() { // With default settings let default_logger = Logger::new();

// With custom settings
let settings = LoggerOptions {
    error_icon: "💥", // the icon for errors
    warn_icon: "⚠️", // the icon for warnings
    info_icon: "ℹ️", // the icon for info
    success_icon: "✅", // the icon for success
    icon_connector: "=>", // the connector between the icon and the message
    log_file: "log.txt", // the file to log to when logging to a file
    highlight: true, // highlight text after ":" in the message
    ..Default::default() // the default values for the non specified settings
}

let custom_logger = settings.get_logger();

} ```

Logging

This code provides the following functions:

• 🟡 warn(): Prints a warning message.
• 🔴 error(): Prints an error message.
• 🔵 info(): Prints an information message.
• 🟢 success(): Prints a success message.
• ℹ️ Add a f before the function name to print the message to the log file

Each function takes a single parameter, which is the message to be printed.

rust logger.error("a command failed : hello"); logger.info("executing command : hello"); logger.warn("a command is about to fail : hello"); logger.success("a command succeeded : hello");

Highlighting 🔍

By default, the text after the colon is highlighted.

This can be disabled by setting the highlight field to false inside the custom settings.

```rs let settings = LoggerOptions { highlight: false, ..Default::default() }

let logger = settings.get_logger(); ```

Icon connector 🔗

By default, the icon and the message are separated by an arrow ->

You can change this by setting the icon_connector field to something else.

```rs let settings = LoggerOptions { icon_connector: "=>", ..Default::default() }

let logger = settings.get_logger(); ```

Icons 🔍

By default, the following icons are used:

| Icon | Function | | ----- | --------- | | [ x ] | error() | | [ i ] | info() | | [ v ] | success() | | [ ! ] | warn() |

You can change this by setting the following fields inside the custom settings:

```rust let settings = LoggerOptions { erroricon: "💥", warnicon: "⚠️", infoicon: "ℹ️", successicon: "✅", ..Default::default() }

let logger = settings.get_logger(); ```

Log file 📄

You can specify the log file path to write the messages to with the log_file field.

Use the f prefix before the function name to print the message to the log file.

```rust let settings = LoggerOptions { log_file: "myProgram.log", ..Default::default() }

let logger = settings.get_logger();

// -----------------------------

logger.fwarning("This is a : warning message"); logger.fsuccess("This is a : success message"); logger.finfo("This is an : information message"); logger.ferror("This is an : error message"); ```

also logging to terminal when logging to file 📄

You can set environment variable LOG to print to also log to the terminal when logging to a file.

```bash LOG=print [program]

#

PROGRAM SOURCE CODE

ferror("This is an : error message");

#

[Terminal output] :

[ x ] -> This is an : error message

#

LOGFILE CONTENT

[ x ] -> This is an : error message

#

```
