has-rs

A simple rust implementation of has by kdabir.

has checks presence of various command line tools on the PATH and reports their installed version.

It should work on Windows, Mac OS, and Linux.

This was created as part of my practice and learning of the Rust programming language. I started this back in August 2022, but I got to releasing this now (October 2024).

This application is lot simpler in the sense that it simply tries to figure the program versions by guessing the version command (such as -v, -V, --version, -version, or just version). This program does not check the PATH variable, system values, or any environment variables.

build & run

You can simply navigate to the has-rs folder and run the following command to build it:

cargo build

... or to run it and check if a system has git, gcc and node installed:

cargo run git gcc node
