semver

A library for working with versions in semver format.

Usage

import semver

fn main() {
    ver1 := semver.from('1.2.4') or {
        println('Invalid version')
        return
    }
    ver2 := semver.from('2.3.4') or {
        println('Invalid version')
        return
    }
    println(ver1.gt(ver2))
    println(ver2.gt(ver1))
    println(ver1.satisfies('>=1.1.0 <2.0.0'))
    println(ver2.satisfies('>=1.1.0 <2.0.0'))
    println(ver2.satisfies('>=1.1.0 <2.0.0 || >2.2.0'))
}

fn build(major int, minor int, patch int) Version

build returns a Version structure with given major, minor and patch versions.

fn coerce(input string) ?Version

• Utilites. coerce converts the input version to a Version struct. coerce will strip any contents after the parsed version string:

fn from(input string) ?Version

• Constructor. from returns a Version structure parsed from input string.

fn is_valid(input string) bool

is_valid returns true if the input string can be converted to a (semantic) Version struct.

enum Increment {
	major
	minor
	patch
}

Increment represents the different types of version increments.

struct Version {
pub:
	major      int
	minor      int
	patch      int
	prerelease string
	metadata   string
}

• Structures. Version represents a semantic version in semver format.

fn (ver Version) increment(typ Increment) Version

• Transformation. increment returns a Version structure with incremented values.

fn (ver Version) satisfies(input string) bool

• Comparison. satisfies returns true if the input expression can be validated to true when run against this Version.

assert semver.build(1,0,0).satisfies('<=2.0.0') == true

assert semver.build(1,0,0).satisfies('>=2.0.0') == false

fn (v1 Version) eq(v2 Version) bool

eq returns true if v1 is equal to v2.

fn (v1 Version) gt(v2 Version) bool

gt returns true if v1 is greater than v2.

fn (v1 Version) lt(v2 Version) bool

lt returns true if v1 is less than v2.

fn (v1 Version) ge(v2 Version) bool

ge returns true if v1 is greater than or equal to v2.

fn (v1 Version) le(v2 Version) bool

le returns true if v1 is less than or equal to v2.
