Available Enhancements

1. Colors and Styling

Add semantic colors to CLI output using owo-colors.

What Gets Added:

• Dependency: owo-colors
• Dependency: supports-color (for detection)
• Color module with semantic helpers
• NO_COLOR environment variable support
• Terminal capability detection

Example Implementation:

// src/colors.rs
use owo_colors::{OwoColorize, Stream};

pub fn success(message: &str) {
    println!(
        "{} {}",
        "✓".if_supports_color(Stream::Stdout, |text| text.green().bold()),
        message
    );
}

pub fn error(message: &str) {
    eprintln!(
        "{} {}",
        "✗".if_supports_color(Stream::Stderr, |text| text.red().bold()),
        message
    );
}

pub fn warning(message: &str) {
    println!(
        "{} {}",
        "⚠".if_supports_color(Stream::Stdout, |text| text.yellow().bold()),
        message
    );
}

pub fn info(message: &str) {
    println!(
        "{} {}",
        "ℹ".if_supports_color(Stream::Stdout, |text| text.blue().bold()),
        message
    );
}

pub fn supports_color() -> bool {
    use supports_color::Stream as ColorStream;
    supports_color::on(ColorStream::Stdout).is_some()
}

Usage in Code:

use crate::colors;

colors::success("Build completed!");
colors::error("Failed to read file");
colors::warning("Configuration incomplete");
colors::info("Processing 10 files");
