lscolors

A cross-platform library for colorizing paths according to the LS_COLORS environment variable (like ls).

Usage

use lscolors::{LsColors, Style};

let lscolors = LsColors::from_env().unwrap_or_default();

let path = "some/folder/test.tar.gz";
let style = lscolors.style_for_path(path);

// If you want to use `ansi_term`:
let ansi_style = style.map(Style::to_ansi_term_style)
                      .unwrap_or_default();
println!("{}", ansi_style.paint(path));

// If you want to use `nu-ansi-term` (fork of ansi_term) or `gnu_legacy`:
let nu_ansi_style = style.map(Style::to_nu_ansi_term_style)
                      .unwrap_or_default();
println!("{}", nu_ansi_style.paint(path));

// If you want to use `crossterm`:
let crossterm_style = style.map(Style::to_crossterm_style)
                      .unwrap_or_default();
println!("{}", crossterm_style.apply(path));

Command-line application

This crate also comes with a small command-line program lscolors that can be used to colorize the output of other commands:

> find . -maxdepth 2 | lscolors

> rg foo -l | lscolors

You can install it by running cargo install lscolors or by downloading one of the prebuilt binaries from the release page. If you want to build the application from source, you can run

cargo build --release --features=nu-ansi-term --locked
