4 | Lightweight library for Android, Java and Kotlin to compare version strings.
5 |
6 | This library allows you to easily compare version strings. Versions can but do not necessarily have to follow the SemVer convention. Any number of version parts as well as common pre-release suffixes will be taken into account.
7 |
8 | Pure Java (java.util), no dependencies, very small method count.
9 |
10 | ## Download [](https://search.maven.org/artifact/io.github.g00fy2/versioncompare)
11 |
12 |
13 | Gradle
14 |
15 | ```kotlin
16 | dependencies {
17 | implementation("io.github.g00fy2:versioncompare:1.5.0")
18 | }
19 | ```
20 |
21 |
22 | Maven
23 |
24 | ```xml
25 |
26 | io.github.g00fy2
27 | versioncompare
28 | 1.5.0
29 |
30 | ```
31 |
32 |
33 | > ⚠️ Starting with version 1.4.0 this library moved to MavenCentral. As a result the *groupId* had to be changed. If you use the old `com.g00fy2:versioncompare` artifact check out the migration guide in the [release notes](https://github.com/G00fY2/version-compare/releases/tag/1.4.0).
34 |
35 | ## Usage
36 | To compare two version strings just create a new Version object. Invalid inputs (*null* or non-numeric first char) will by default be handled as `0.0.0`.
37 |
38 |
39 | Kotlin
40 |
41 | You can use the default [comparison operators](https://kotlinlang.org/docs/operator-overloading.html#comparison-operators) to compare version objects:
42 |
43 | ```kotlin
44 | var result: Boolean
45 |
46 | result = Version("1.2.1") > Version("1.2") // result = true
47 |
48 | result = Version("1.0.2-rc2") < Version("1.0.2-rc3") // result = true
49 |
50 | result = Version("1.3") == Version("1.3.0") // result = true
51 |
52 | result = Version("2.1.0") >= Version("2.0") // result = true
53 |
54 | result = Version("2.0.0-beta") >= Version("2.0") // result = false
55 | result = Version("2.0.0-beta").isAtLeast("2.0", /* ignoreSuffix: */ true) // result = true
56 | ```
57 |
58 |
59 |
60 | Java
61 |
62 | ```java
63 | boolean result;
64 |
65 | result = new Version("1.2.1").isHigherThan("1.2"); // result = true
66 |
67 | result = new Version("1.0.2-rc2").isLowerThan("1.0.2-rc3"); // result = true
68 |
69 | result = new Version("1.3").isEqual("1.3.0"); // result = true
70 |
71 | result = new Version("2.0.0-beta").isAtLeast("2.0"); // result = false
72 | result = new Version("2.0.0-beta").isAtLeast("2.0", /* ignoreSuffix: */ true); // result = true
73 | ```
74 |
75 |
76 | ### For more detailed usage, check out the [documentation](https://g00fy2.github.io/version-compare/io/github/g00fy2/versioncompare/Version.html).
77 |
78 | ## Version structure example
79 | ```
80 | Version 1.7.3-rc2.xyz
81 | +-------+ +-------+ +-------+ +-------+
82 | String | 1 | . | 7 | . | 3-rc2 | . | xyz |
83 | +-------+ +-------+ +-------+ +-------+
84 | | | | | |
85 | major [1] <-- | | ---- |
86 | minor [7] <-------------- | | ----
87 | patch [3] <------------------------ ||
88 | ... +------------+
89 | suffix | -rc2.xyz |
90 | +------------+
91 | -------------------------------------------------------------------------
92 | suffix compare logic ||
93 | ----- -----
94 | | |
95 | +-------+ +-------+
96 | detected pre-release | rc2 | | .xyz | ignored part
97 | +-------+ +-------+
98 | ||
99 | --- ---
100 | | |
101 | +----+ +---+
102 | | rc | | 2 | pre-release build
103 | +----+ +---+
104 | ```
105 |
106 | **Notes:**
107 | * expected separator between version numbers is `.`
108 | * suffix and pre-release number do **not need** a special separator `1.1rc == 1.1.rc == 1.1-rc`
109 |
110 | ### Supported pre-release suffixes
111 | | order | suffix |
112 | | ----- | --------- |
113 | | 5 | *empty* or *unknown* |
114 | | 4 | rc |
115 | | 3 | beta |
116 | | 2 | alpha |
117 | | 1 | pre + alpha |
118 | | 0 | snapshot |
119 |
120 | **Notes:**
121 | * higher order results in higher version `1.0 > 1.0-beta`
122 | * pre-release builds (except for snapshots) are supported `1.0-rc3 > 1.0-rc2`
123 |

21 | # Gradle start up script for POSIX generated by Gradle.
22 | #
23 | # Important for running:
24 | #
25 | # (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
26 | # noncompliant, but you have some other compliant shell such as ksh or
27 | # bash, then to run this script, type that shell name before the whole
28 | # command line, like:
29 | #
30 | # ksh Gradle
31 | #
32 | # Busybox and similar reduced shells will NOT work, because this script
33 | # requires all of these POSIX shell features:
34 | # * functions;
35 | # * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
36 | # «${var#prefix}», «${var%suffix}», and «$( cmd )»;
37 | # * compound commands having a testable exit status, especially «case»;
38 | # * various built-in commands including «command», «set», and «ulimit».
39 | #
40 | # Important for patching:
41 | #
42 | # (2) This script targets any POSIX shell, so it avoids extensions provided
43 | # by Bash, Ksh, etc; in particular arrays are avoided.
44 | #
45 | # The "traditional" practice of packing multiple parameters into a
46 | # space-separated string is a well documented source of bugs and security
47 | # problems, so this is (mostly) avoided, by progressively accumulating
48 | # options in "$@", and eventually passing that to Java.
49 | #
50 | # Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
51 | # and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
52 | # see the in-line comments for details.
53 | #
54 | # There are tweaks for specific operating systems such as AIX, CygWin,
55 | # Darwin, MinGW, and NonStop.
56 | #
57 | # (3) This script is generated from the Groovy template
58 | # https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
