About:
Faketty is a command-line wrapper that executes a subprocess within a pseudo-terminal (PTY), preserving interactive behavior even when stdout or stderr are redirected. This ensures that programs like `ls`, `grep`, or package managers produce colorized output and behave as if attached to a real terminal. It is a lightweight utility written in Rust, designed for reliability and cross-platform compatibility.

Key Features:

Preserves interactive program behavior and TTY features
Forces colorized output even when piping or redirecting
Written in Rust for performance and safety
Simple, single-binary CLI tool

Use Cases:

Capturing colorized output from tools like `ls` or `grep` into a log file
Forcing interactive prompts in scripts that would otherwise disable them
Debugging build systems or CI pipelines that redirect output

Alternatives:

script – Standard Unix tool for emulating a terminal, but less convenient for simple command wrapping
unbuffer (expect) – Part of the Expect suite; heavier dependency and less modern than faketty
