The `StrictNewVersion` -function only parses valid version 2 semantic versions as outlined in the -specification. The `NewVersion` function attempts to coerce a version into a -semantic version and parse it. For example, if there is a leading v or a version -listed without all 3 parts (e.g. `v1.2`) it will attempt to coerce it into a valid -semantic version (e.g., 1.2.0). In both cases a `Version` object is returned -that can be sorted, compared, and used in constraints. - -When parsing a version an error is returned if there is an issue parsing the -version. For example, - - v, err := semver.NewVersion("1.2.3-beta.1+build345") - -The version object has methods to get the parts of the version, compare it to -other versions, convert the version back into a string, and get the original -string. Getting the original string is useful if the semantic version was coerced -into a valid form. - -## Sorting Semantic Versions - -A set of versions can be sorted using the `sort` package from the standard library. -For example, - -```go -raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",} -vs := make([]*semver.Version, len(raw)) -for i, r := range raw { - v, err := semver.NewVersion(r) - if err != nil { - t.Errorf("Error parsing version: %s", err) - } - - vs[i] = v -} - -sort.Sort(semver.Collection(vs)) -``` - -## Checking Version Constraints - -There are two methods for comparing versions. One uses comparison methods on -`Version` instances and the other uses `Constraints`. There are some important -differences to notes between these two methods of comparison. - -1. When two versions are compared using functions such as `Compare`, `LessThan`, - and others it will follow the specification and always include prereleases - within the comparison. It will provide an answer that is valid with the - comparison section of the spec at https://semver.org/#spec-item-11 -2. When constraint checking is used for checks or validation it will follow a - different set of rules that are common for ranges with tools like npm/js - and Rust/Cargo. This includes considering prereleases to be invalid if the - ranges does not include one. If you want to have it include pre-releases a - simple solution is to include `-0` in your range. -3. Constraint ranges can have some complex rules including the shorthand use of - ~ and ^. For more details on those see the options below. - -There are differences between the two methods or checking versions because the -comparison methods on `Version` follow the specification while comparison ranges -are not part of the specification. Different packages and tools have taken it -upon themselves to come up with range rules. This has resulted in differences. -For example, npm/js and Cargo/Rust follow similar patterns while PHP has a -different pattern for ^. The comparison features in this package follow the -npm/js and Cargo/Rust lead because applications using it have followed similar -patters with their versions. - -Checking a version against version constraints is one of the most featureful -parts of the package. - -```go -c, err := semver.NewConstraint(">= 1.2.3") -if err != nil { - // Handle constraint not being parsable. -} - -v, err := semver.NewVersion("1.3") -if err != nil { - // Handle version not being parsable. -} -// Check if the version meets the constraints. The a variable will be true. -a := c.Check(v) -``` - -### Basic Comparisons - -There are two elements to the comparisons. First, a comparison string is a list -of space or comma separated AND comparisons. These are then separated by || (OR) -comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a -comparison that's greater than or equal to 1.2 and less than 3.0.0 or is -greater than or equal to 4.2.3. - -The basic comparisons are: - -* `=`: equal (aliased to no operator) -* `!=`: not equal -* `>`: greater than -* `<`: less than -* `>=`: greater than or equal to -* `<=`: less than or equal to - -### Working With Prerelease Versions - -Pre-releases, for those not familiar with them, are used for software releases -prior to stable or generally available releases. Examples of prereleases include -development, alpha, beta, and release candidate releases. A prerelease may be -a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the -order of precedence, prereleases come before their associated releases. In this -example `1.2.3-beta.1 < 1.2.3`. - -According to the Semantic Version specification prereleases may not be -API compliant with their release counterpart. It says, - -> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version. - -SemVer comparisons using constraints without a prerelease comparator will skip -prerelease versions. For example, `>=1.2.3` will skip prereleases when looking -at a list of releases while `>=1.2.3-0` will evaluate and find prereleases. - -The reason for the `0` as a pre-release version in the example comparison is -because pre-releases can only contain ASCII alphanumerics and hyphens (along with -`.` separators), per the spec. Sorting happens in ASCII sort order, again per the -spec. The lowest character is a `0` in ASCII sort order -(see an [ASCII Table](http://www.asciitable.com/)) - -Understanding ASCII sort ordering is important because A-Z comes before a-z. That -means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case -sensitivity doesn't apply here. This is due to ASCII sort ordering which is what -the spec specifies. - -### Hyphen Range Comparisons - -There are multiple methods to handle ranges and the first is hyphens ranges. -These look like: - -* `1.2 - 1.4.5` which is equivalent to `>= 1.2 <= 1.4.5` -* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5` - -### Wildcards In Comparisons - -The `x`, `X`, and `*` characters can be used as a wildcard character. This works -for all comparison operators. When used on the `=` operator it falls -back to the patch level comparison (see tilde below). For example, - -* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` -* `>= 1.2.x` is equivalent to `>= 1.2.0` -* `<= 2.x` is equivalent to `< 3` -* `*` is equivalent to `>= 0.0.0` - -### Tilde Range Comparisons (Patch) - -The tilde (`~`) comparison operator is for patch level ranges when a minor -version is specified and major level changes when the minor number is missing. -For example, - -* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0` -* `~1` is equivalent to `>= 1, < 2` -* `~2.3` is equivalent to `>= 2.3, < 2.4` -* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` -* `~1.x` is equivalent to `>= 1, < 2` - -### Caret Range Comparisons (Major) - -The caret (`^`) comparison operator is for major level changes once a stable -(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts -as the API stability level. This is useful when comparisons of API versions as a -major change is API breaking. For example, - -* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` -* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` -* `^2.3` is equivalent to `>= 2.3, < 3` -* `^2.x` is equivalent to `>= 2.0.0, < 3` -* `^0.2.3` is equivalent to `>=0.2.3 <0.3.0` -* `^0.2` is equivalent to `>=0.2.0 <0.3.0` -* `^0.0.3` is equivalent to `>=0.0.3 <0.0.4` -* `^0.0` is equivalent to `>=0.0.0 <0.1.0` -* `^0` is equivalent to `>=0.0.0 <1.0.0` - -## Validation - -In addition to testing a version against a constraint, a version can be validated -against a constraint. When validation fails a slice of errors containing why a -version didn't meet the constraint is returned. For example, - -```go -c, err := semver.NewConstraint("<= 1.2.3, >= 1.4") -if err != nil { - // Handle constraint not being parseable. -} - -v, err := semver.NewVersion("1.3") -if err != nil { - // Handle version not being parseable. -} - -// Validate a version against a constraint. -a, msgs := c.Validate(v) -// a is false -for _, m := range msgs { - fmt.Println(m) - - // Loops over the errors which would read - // "1.3 is greater than 1.2.3" - // "1.3 is less than 1.4" -} -``` - -## Contribute - -If you find an issue or want to contribute please file an [issue](https://github.com/Masterminds/semver/issues) -or [create a pull request](https://github.com/Masterminds/semver/pulls). - -## Security - -Security is an important consideration for this project.

It will provide an answer valid with the comparison - spec section at https://semver.org/#spec-item-11 - 2. When constraint checking is used for checks or validation it will follow a - different set of rules that are common for ranges with tools like npm/js - and Rust/Cargo. This includes considering prereleases to be invalid if the - ranges does not include on. If you want to have it include pre-releases a - simple solution is to include `-0` in your range. - 3. Constraint ranges can have some complex rules including the shorthard use of - ~ and ^. For more details on those see the options below. - -There are differences between the two methods or checking versions because the -comparison methods on `Version` follow the specification while comparison ranges -are not part of the specification. Different packages and tools have taken it -upon themselves to come up with range rules. This has resulted in differences. -For example, npm/js and Cargo/Rust follow similar patterns which PHP has a -different pattern for ^. The comparison features in this package follow the -npm/js and Cargo/Rust lead because applications using it have followed similar -patters with their versions. - -Checking a version against version constraints is one of the most featureful -parts of the package. - - c, err := semver.NewConstraint(">= 1.2.3") - if err != nil { - // Handle constraint not being parsable. - } - - v, err := semver.NewVersion("1.3") - if err != nil { - // Handle version not being parsable. - } - // Check if the version meets the constraints. The a variable will be true. - a := c.Check(v) - -# Basic Comparisons - -There are two elements to the comparisons. First, a comparison string is a list -of comma or space separated AND comparisons. These are then separated by || (OR) -comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a -comparison that's greater than or equal to 1.2 and less than 3.0.0 or is -greater than or equal to 4.2.3. This can also be written as -`">= 1.2, < 3.0.0 || >= 4.2.3"` - -The basic comparisons are: - - - `=`: equal (aliased to no operator) - - `!=`: not equal - - `>`: greater than - - `<`: less than - - `>=`: greater than or equal to - - `<=`: less than or equal to - -# Hyphen Range Comparisons - -There are multiple methods to handle ranges and the first is hyphens ranges. -These look like: - - - `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5` - - `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5` - -# Wildcards In Comparisons - -The `x`, `X`, and `*` characters can be used as a wildcard character. This works -for all comparison operators. When used on the `=` operator it falls -back to the tilde operation. For example, - - - `1.2.x` is equivalent to `>= 1.2.0 < 1.3.0` - - `>= 1.2.x` is equivalent to `>= 1.2.0` - - `<= 2.x` is equivalent to `<= 3` - - `*` is equivalent to `>= 0.0.0` - -Tilde Range Comparisons (Patch) - -The tilde (`~`) comparison operator is for patch level ranges when a minor -version is specified and major level changes when the minor number is missing. -For example, - - - `~1.2.3` is equivalent to `>= 1.2.3 < 1.3.0` - - `~1` is equivalent to `>= 1, < 2` - - `~2.3` is equivalent to `>= 2.3 < 2.4` - - `~1.2.x` is equivalent to `>= 1.2.0 < 1.3.0` - - `~1.x` is equivalent to `>= 1 < 2` - -Caret Range Comparisons (Major) - -The caret (`^`) comparison operator is for major level changes once a stable -(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts -as the API stability level. This is useful when comparisons of API versions as a -major change is API breaking.
