colorize's Introduction

colorize

libcolorize provide simple text colorization for terminal emulator, using ansi escape characters.

To build libcolorize just do :

> rustc lib.rs

libcolorize is really simple to use, see this short example !

extern crate colorize;
// Import the trait implemented for &'static str and ~str
use colorize::AnsiColor;
// Import the colors for the global
use colorize::{BrightRed, Blue};

pub fn main() {
    // Set some global colors
    colorize::global_fg(BrightRed);
    colorize::global_bg(Blue);
    // ^~~~ These settings are reset to default at the end.

    // You can use specific colors or style on a given str,
    // the globals colors are restored after !

    // Write a green underlined text on a yellow background !
    println!("{}", "Hello World !".green().underlined().yellowb());

    // Use bright or normal colors
    println!("{}", "Bright Green foreground and Magenta background !".b_green().magentab());
}

colorize's Issues

Doesn't print on print! Only works on println!

So I am currently working on a shell and I am using it to print the ">" in the color green or red depending on the exit code. I can't make it work. Can you help?

build error

hi @jeremyletang
check this build error.
happy coding~ ;)

Fix example code in README

Code:

extern crate colorize;
// Import the trait implemented for &'static str and ~str
use colorize::AnsiColor;
// Import the colors for the global
use colorize::{BrightRed, Blue};

pub fn main() {
    // Set some global colors
    colorize::global_fg(BrightRed);
    colorize::global_bg(Blue);
    // ^~~~ These settings are reset to default at the end.

    // You can use specific colors or style on a given str,
    // the globals colors are restored after !

    // Write a green underlined text on a yellow background !
    println!("{}", "Hello World !".greenf().underline().yellowb());

    // Use bright or normal colors
    println!("{}", "Bright Green foreground and Magenta background !".b_greenf().magentab());
}
