SemVer

SemVer for 4D

Usage

Create an instance of SemVer to use it later.

$semver:=cs.SemVer.Instance.new()

Version object

Create version object

from string

$version:=$semver.version("1.2.3")
$version:=$semver.version("1.2") // 1.2.0

from digits

$version:=$semver.version(1;2;3)

from collection

$version:=$semver.version(New collection(1;2;3))

Attribute of version object

$version.major
$version.minor
$version.patch

Extract digits

You can extract specific digit without creating Version object

$semver.major("1.2.3") // 1
$semver.minor("1.2.3") // 2
$semver.patch("1.2.3") // 3

But if you need to extract all the digits, prefer use Version object

Check if version string is valid

$semver.valid("1.2.3") // True
$semver.valid("not.a.version") // False

Compare version

comparator

$semver.compare(semver.v0; $semver.v1)

• return 0 if equals
• return 1 if first argument is greater
• return -1 if first argument is lower

equality

semver.eq($semver.v1;"1.0.0")

greater

$semver.gt($semver.v1; "0.9.0")
$semver.gt("0.9.2"; "0.9.0")
$semver.gt("1.0.0"; "0.9.0")

greater or equals than

$semver.gte("1.5.6"; "0.9.0")

lower than

$semver.lt("0.5.6"; "0.9.0")

lower or equals than

$semver.lte("0.5.6"; "0.9.0")

Range object

A range object contains two versions, the min and the max and allow to check if a version satisfy this bounds.

Create range object

with two min/max version from collection or object

$range:=$semver.range(New collection("1.0.1"; "1.2.1"))
$range:=$semver.range(New object("min"; "1.0.1"; "max"; "1.2.1"))

from exact version

$version:=$semver.range("1.2.3")
$version:=$semver.range($semver.version("1.2.3"))

min and max will be equals

from string

to specify a range of stable versions

Use >, <, =, >= or <= for comparisons, or - to specify an inclusive range

examples:

• >2.1
• 1.0.0 - 1.2.0

to include everything greater than a particular version in the same minor range

Use the tilde symbol, ~

examples:

• ~2.2.0

to include everything greater than a particular version in the same major range

Use the caret (aka hat) symbol, ^

examples:

• ^2.2.1
• ^0.1.0

Check if version satisfy a range

$valid:=semver.range(">1").satisfiedBy("1.5.1")
$valid:=semver.range("1.0.0 - 1.2.0").satisfiedBy("1.5.1")
$valid:=semver.range("^1.0.0").satisfiedBy("1.5.1")

TODO

• increment functions
• is valid function
• compare two versions
• check if version satisfy simple range
• compare version with special syntax like "<=2.5.0 || 5.0.0 - 7.2.3"
• support suffix(-prerelease and +build)
• support wildcards *,x,X
• support just two number with space and operators like ">= 1.2 < 3.0.0"
• clean version string (coerce)
