Ver-CMP

A useful cli-tool and library for compairing semantic versions

Cli App

Cli Installation

To build the cli tool, run the following command:

cargo build --bin ver_cmp_cli --features build-binary --release

Cli Usage

ver-cmp --ver1 0.2.3 --ver2 0.2.1

Returns the following

0.2.3

[!TIP] You can use the -c or --compare flag to return a 0 1 or 2 for greater, less, or equal respectively to easily pipe the output to other commands

Library

This example shows how to use the library to compare two versions and how to handle the result

use ver_cmp::*;

fn main() {
    let ver1 = "1.1.5";
    let ver2 = "1.0.3";
    let result = compare_versions(ver1, ver2);

    match result {
        Ok(Ordering::Greater) => println!("{} > {}", ver1, ver2),
        Ok(Ordering::Less) => println!("{} < {}", ver1, ver2),
        Ok(Ordering::Equal) => println!("{} == {}", ver1, ver2),
        Err(e) => println!("Error: {}", e),
    }
}
