Crate jt_consoleutils 

Console and shell utilities for Rust CLI tools.

jt-consoleutils provides a set of composable building blocks used across CLI tools in the jt-* ecosystem. Everything is designed to be testable: traits with mock/test implementations are provided for every abstraction that touches I/O or process execution.

Modules at a glance

Module	What it provides
output	output::Output trait, output::ConsoleOutput, output::StringOutput, output::OutputMode
shell	shell::Shell trait, shell::ProcessShell, shell::DryRunShell, shell::MockShell
colorize	Rainbow ANSI colorizer
colors	ANSI escape-code constants
help	Help / version printing helpers
terminal	Terminal width detection
str_utils	Human-readable byte formatting and other string helpers
fs_utils	Filesystem comparison and permission helpers
version	Build-info version string formatter
build_support (feature build-support)	build.rs helper that emits BUILD_DATE / GIT_HASH

Quick start — output

use jt_consoleutils::output::{ConsoleOutput, Output, OutputMode};

let mode = OutputMode { verbose: false, quiet: false, dry_run: false };
let mut out = ConsoleOutput::new(mode);
out.writeln("Hello, world!");

Quick start — shell

use jt_consoleutils::shell;
use jt_consoleutils::output::{StringOutput, OutputMode};

let mode = OutputMode::default();
let sh = shell::create(/*dry_run=*/ false);
// sh is a Box<dyn Shell> backed by ProcessShell.

Modules
