<artifactId>npm-semver</artifactId>
<version>1.0.0</version>
</dependency>
Gradle configuration
compile group: "com.github.yuchi", name: "npm-semver", version: "1.0.0"
// or
compile "com.github.yuchi:npm-semver:1.0.0"
Quick usage
Version version = Version.from("1.2.3");
Range range = Range.from("^1.2.0");
range.test(version) // true
Full Usage
Version comparison
boolean loose = false;
Version v1 = Version.from("1.2.3", loose);
String v2 = Version.from("1.3.0", loose);
v1.compareTo(v2); // -1
v2.compareTo(v1); // +1
v1.compareTo(v1); // 0
In Range tests
boolean loose = false;
Version v = Version.from("1.2.3", loose);
Range r = Range.from("^1.0.0", loose);
r.test(v); // true
Range boundaries test
boolean loose = false;
SemVer.isGreaterThenRange("1.3.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isGreaterThenRange("1.5.0", ">1.0.0 <1.4.0", loose); // true
SemVer.isGreaterThenRange("0.9.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isLessThenRange("1.3.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isLessThenRange("1.5.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isLessThenRange("0.9.0", ">1.0.0 <1.4.0", loose); // true
Sorting
List<Version> versions = new ArrayList<Version>();
versions.add(Version.from("4.2.0", false));
versions.add(Version.from("1.8.0", false));
versions.add(Version.from("1.2.0", false));
versions.sort(new VersionComparator()); // { "4.2.0", "1.8.0", "1.2.0" }
Versions Stream filtering
List<Version> versions = new ArrayList<Version>();
versions.add(Version.from("4.2.0", false));
versions.add(Version.from("1.8.0", false));
versions.add(Version.from("1.2.0", false));
Range range = Range.from(">3.0.0", false);
version.stream().filter(range::test); // { "4.2.0" }
Publishing
$ trash build
$ trash tmp
$ mkdir tmp
$ gradle clean preparePublish publish
$ gradle clean preparePublish publish # yes you need to launch it twice
