Function chocodye::ansi_text

pub fn ansi_text(bg: Rgb, s: &str) -> String

Changes the background color of a string using three ANSI escape codes if the terminal support truecolors.

If the environment variable COLORTERM is not defined or contains neither truecolor nor 24bit, the string parameter is returned as is.

This function also changes the foreground color according to the specified background color in order to ensure that the text is visible.

Examples

use chocodye::{Rgb, ansi_text};
use std::env;

env::remove_var("COLORTERM");
assert_eq!(ansi_text(Rgb::RED, "hello world!"), "hello world!");

env::set_var("COLORTERM", "truecolor");
assert_eq!(ansi_text(Rgb::RED, "hello world!"), "\x1B[48;2;255;0;0m\x1B[38;2;255;255;255mhello world!\x1B[0m");
