nu_plugin_ls_colorize

A simple plugin for Nushell which colorizes paths according to the builtin ls colors or the LS_COLORS environment variable (if set). In most cases, a colorized path should look the exact same as it would in ls or ls | grid -c when printed.

Installing

cargo install nu_plugin_ls_colorize
plugin add ~/.cargo/bin/nu_plugin_ls_colorize

Usage

Colorize a single path

let colorized = $env.PWD | ls-colorize
$colorized | debug -v
#
# "\u{1b}[38;5;81m/current/working/directory\u{1b}[0m"

Colorize a list of paths

cd nu_plugin_ls_colorize
let colorized = ls | get name | ls-colorize
$colorized | debug -v
