Colored Next (CNXT)

An enhanced fork of colored offering superior performance and terminal handling.

Why CNXT?

1. Optimized Performance: Utilizes Cow for intelligent memory management (Inspired by this PR)
2. Modern Codebase: Removed legacy code and streamlined implementation
3. Advanced Terminal Support: Sophisticated terminal capability detection with automatic color downgrading

Usage

Coloring your terminal made simple. You already know how to do it.

Essential Configuration

1. For Windows targets, add this to enable colors in Windows CMD:

   #[cfg(windows)]
   cnxt::control::set_virtual_terminal(true);
   

   Comparison showing how Windows CMD displays colors before and after enabling virtual terminal.

   

2. CNXT dynamically detects terminal color support across three tiers:

   • Ansi16 (16 colors)
   • Ansi256 (256 colors)
   • TrueColor

   When using colors beyond your terminal's capabilities, CNXT automatically downgrades them to the maximum supported level.

   Manual control options:

   use cnxt::control::{set_should_colorize, ShouldColorize};
   
   // Environment-based detection level (default)
   set_should_colorize(ShouldColorize::from_env());
   
   // Explicit configuration
   set_should_colorize(ShouldColorize::YesWithTrueColor);  // Force truecolor
   set_should_colorize(ShouldColorize::YesWithAnsi256);    // Force 256-color
   set_should_colorize(ShouldColorize::No);                // Disable colors
   set_should_colorize(ShouldColorize::Yes);               // Enable colors with auto-detect level
   
   // Manual color fallback
   use cnxt::Color;
   
   let truecolor = Color::TrueColor { r: 166, g: 227, b: 161 };
   let ansi16 = truecolor.fallback_to_ansi16();
   let ansi256 = truecolor.fallback_to_ansi256();
   

Features

1. terminal-detection (Enabled by default):

   Automatically detects terminal color support and downgrades colors accordingly.

   Defaultly use TrueColor if disable this feature.

2. conditional-coloring : Provide helper functions to colorize strings based on conditions.

   use cnxt::Colorize as _;
   
   println!("{}", "red".red_if(true)); // print red color
   println!("{}", "red".red_if(false)); // print no color
   
   println!("{}", "green".green().red_if(false)); // print green color
