ReColored

This is a fork of colored. It is named recolored in order to be usable on crates.io.

The following is the original README, if you want to use this fork, you will need to replace colored by recolored.

Coloring terminal so simple, you already know how to do it!

    "this is blue".blue();
    "this is red".red();
    "this is red on blue".red().on_blue();
    "this is also red on blue".on_blue().red();
    "bright colors are welcome as well".on_bright_blue().bright_red();
    "or any rgb color".true_color(171, 205, 239);
    "or any hexadecimal color".hex_color(0xabcdef);
    "or use colors from the palette".palette(36);
    "you can also make bold comments".bold();
    println!("{} {} {}", "or use".cyan(), "any".italic().yellow(), "string type".cyan());
    "or change advice. This is red".yellow().blue().red();
    "or clear things up. This is default color and style".red().bold().clear();
    "purple and magenta are the same".purple().magenta();
    "and so are normal and clear".normal().clear();
    "you can specify color by string".color("blue").on_color("red");
    String::from("this also works!").green().bold();
    format!("{:30}", "format works as expected. This will be padded".blue());
    format!("{:.3}", "and this will be green but truncated to 3 chars".green());

How to use

Add this in your Cargo.toml:

[dependencies]
colored = "1.9"

and add this to your lib.rs or main.rs:

    extern crate recolored; // not needed in Rust 2018

    use recolored::*;

    // test the example with `cargo run --example most_simple`
    fn main() {
        // TADAA!
        println!("{} {} !", "it".green(), "works".blue().bold());
    }

Features

• Safe rust, easy to use, minimal dependencies, complete test suite
• Respect the CLICOLOR/CLICOLOR_FORCE behavior (see the specs)
• Respect the NO_COLOR behavior (see the specs)
• Works on Linux, MacOS, and Windows (Powershell)

Colors:

• black
• red
• green
• yellow
• blue
• magenta (or purple)
• cyan
• white

Bright colors: prepend the color by bright_. So easy. Background colors: prepend the color by on_. Simple as that. Bright Background colors: prepend the color by on_bright_. Not hard at all. Any 8-bit palette color: use palette(u8). Super simple. Any RGB color: use true_color(u8, u8, u8). Really easy. Any hexadecimal color: use hex_color(0xABCDEF). Far from difficult.

Styles:

• bold
• underline
• italic
• dimmed
• reversed
• blink
• hidden
• strikethrough

You can clear color and style anytime by using normal() or clear()

Advanced Control:

Dynamic color from str

As Color implements FromStr, From<&str>, and From<String>, you can easily cast a string into a color like that:

// the easy way
"blue string yo".color("blue");

// this will default to white
"white string".color("zorglub");

// the safer way via a Result
let color_res : Result<Color, ()> = "zorglub".parse();
"red string".color(color_res.unwrap_or(Color::Red));

Colorization control

If you want to disable any coloring at compile time, you can simply do so by using the no-color feature.

For example, you can do this in your Cargo.toml to disable color in tests:

[features]
# this effectively enable the feature `no-color` of colored when testing with
# `cargo test --feature dumb_terminal`
dumb_terminal = ["colored/no-color"]

You can use have even finer control by using the colored::control::set_override method.
