A library for parsing and comparing software version numbers.
We like to give version numbers to our software in a myriad of different ways. Some ways follow strict guidelines for incrementing and comparison. Some follow conventional wisdom and are generally self-consistent. Some are just plain asinine. This library provides a means of parsing and comparing any style of versioning, be it a nice Semantic Version like this:
1.2.3-r1
...or a monstrosity like this:
2:10.2+0.0093r3+1-1
For the Haskell version of this library, see here.
use versions::Versioning;
let good = Versioning::new("1.6.0").unwrap();
let evil = Versioning::new("1.6.0a+2014+m872b87e73dfb-1").unwrap();
assert!(good.is_ideal()); // It parsed as a `SemVer`.
assert!(evil.is_complex()); // It parsed as a `Mess`.
assert!(good > evil); // We can compare them anyway!
