The blazing fast way to check what version of grep you’re using, written in Rust.

This is a Rust rewrite of the version tool written by Keith Peters. I wanted to write a complete project in Rust that I would actually find useful, and I thought it would be funny to rewrite such a simple tool in Rust. The code is super messy for now, I just got the main functionality working and am going back to refactor it into something maintainable.

Usage

To get the version of a tool, use:

version <tool name>

For example:

$ version python3
Command: python3 -V
Python 3.9.5

To get a list of all the tools that version knows about, run:

version --list

Installation

If you don’t have the Rust toolchain, you can install it using rustup, then run:

cargo install --git "https://github.com/Hasnep/version.git"
