# semver

[![Build Status](https://travis-ci.org/gernest/semver.svg?branch=master)](https://travis-ci.org/gernest/semver)

semantic versioning for zig. This allows you to parse and compare semantic version strings.

## usage

```

const semver = @import("src/main.zig");

const warn = @import("std").debug.warn;

test "parse version string to a struct" {

    const version = try semver.parse("v1.2.3-pre+meta");

    warn("\n{}\n", version);

}

test "compare two version strings" {

    const versionSample = struct {

        x: []const u8,

        y: []const u8,

    };

    const version_list = []versionSample{

        versionSample{ .x = "1.2.3", .y = "3.2.1" },

        // you can prefix the version string with v, it is supported.

        versionSample{ .x = "v5.2.3", .y = "v3.2.1" },

    };

    warn("\n");

    for (version_list) |v| {

        const cmp = try semver.compare(v.x, v.y);

        switch (cmp) {

            semver.Comparison.LessThan => {

                warn("{} < {}\n", v.x, v.y);

            },

            semver.Comparison.Equal => {

                warn("{} == {}\n", v.x, v.y);

            },

            semver.Comparison.GreaterThan => {

                warn("{} > {}\n", v.x, v.y);

            },

            else => unreachable,

        }

    }

}

// $ zig test example.zig

// Test 1/2 parse version string to a struct...

// Version{ .major = 1, .minor = 2, .patch = 3, .pre_release = pre, .build = meta }

// OK

// Test 2/2 compare two version strings...

// 1.2.3 < 3.2.1

// v5.2.3 > v3.2.1

// OK

// All tests passed.
