# SemVer
The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
* Parse semantic versions
* Sort semantic versions
* Check if a semantic version fits within a set of constraints
* Optionally work with a `v` prefix
[![Stability:
Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
[![Build Status](https://travis-ci.org/Masterminds/semver.svg)](https://travis-ci.org/Masterminds/semver) [![Build status](https://ci.appveyor.com/api/projects/status/jfk66lib7hb985k8/branch/master?svg=true&passingText=windows%20build%20passing&failingText=windows%20build%20failing)](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [![GoDoc](https://godoc.org/github.com/Masterminds/semver?status.svg)](https://godoc.org/github.com/Masterminds/semver) [![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
## Parsing Semantic Versions
To parse a semantic version use the `NewVersion` function. For example,
```go
v, err := semver.NewVersion("1.2.3-beta.1+build345")
```
If there is an error the version wasn't parseable. 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. For more details
please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
## Sorting Semantic Versions
A set of versions can be sorted using the [`sort`](https://golang.org/pkg/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
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 parseable.
}
v, _ := semver.NewVersion("1.3")
if err != nil {
// Handle version not being parseable.
}
// 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 separated and comparisons. These are then separated by || separated 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
_Note, according to the Semantic Version specification pre-releases 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 without a pre-release value will skip pre-release versions.
For example, `>1.2.3` will skip pre-releases when looking at a list of values
while `>1.2.3-alpha.1` will evaluate pre-releases._
## 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 pack 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. 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`
# 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, _ := 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"
}
```

/*
Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
Specifically it provides the ability to:
* Parse semantic versions
* Sort semantic versions
* Check if a semantic version fits within a set of constraints
* Optionally work with a `v` prefix
Parsing Semantic Versions
To parse a semantic version use the `NewVersion` function. For example,
v, err := semver.NewVersion("1.2.3-beta.1+build345")
If there is an error the version wasn't parseable. 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. For more details
please see the documentation at https://godoc.org/github.com/Masterminds/semver.
Sorting Semantic Versions
A set of versions can be sorted using the `sort` package from the standard library.
For example,
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
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 parseable.
}
v, _ := semver.NewVersion("1.3")
if err != nil {
// Handle version not being parseable.
}
// 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 separated and comparisons. These are then separated by || separated 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
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 pack 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. 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`

# Changelog
## 3.1.0 (2020-04-15)
### Added
- #131: Add support for serializing/deserializing SQL (thanks @ryancurrah)
### Changed
- #148: More accurate validation messages on constraints
## 3.0.3 (2019-12-13)
### Fixed
- #141: Fixed issue with <= comparison
## 3.0.2 (2019-11-14)
### Fixed
- #134: Fixed broken constraint checking with ^0.0 (thanks @krmichelos)
## 3.0.1 (2019-09-13)
### Fixed
- #125: Fixes issue with module path for v3
## 3.0.0 (2019-09-12)
This is a major release of the semver package which includes API changes. The Go
API is compatible with ^1. The Go API was not changed because many people are using
`go get` without Go modules for their applications and API breaking changes cause
errors which we have or would need to support.
The changes in this release are the handling based on the data passed into the
functions. These are described in the added and changed sections below.
### Added
- StrictNewVersion function. This is similar to NewVersion but will return an
error if the version passed in is not a strict semantic version. For example,
1.2.3 would pass but v1.2.3 or 1.2 would fail because they are not strictly
speaking semantic versions. This function is faster, performs fewer operations,
and uses fewer allocations than NewVersion.
- Fuzzing has been performed on NewVersion, StrictNewVersion, and NewConstraint.
The Makefile contains the operations used. For more information on you can start
on Wikipedia at https://en.wikipedia.org/wiki/Fuzzing
- Now using Go modules
### Changed
- NewVersion has proper prerelease and metadata validation with error messages
to signal an issue with either of them
- ^ now operates using a similar set of rules to npm/js and Rust/Cargo. If the
version is >=1 the ^ ranges works the same as v1. For major versions of 0 the
rules have changed. The minor version is treated as the stable version unless
a patch is specified and then it is equivalent to =. One difference from npm/js
is that prereleases there are only to a specific version (e.g. 1.2.3).
Prereleases here look over multiple versions and follow semantic version
ordering rules. This pattern now follows along with the expected and requested
handling of this packaged by numerous users.
## 1.5.0 (2019-09-11)
### Added
- #103: Add basic fuzzing for `NewVersion()` (thanks @jesse-c)
### Changed
- #82: Clarify wildcard meaning in range constraints and update tests for it (thanks @greysteil)

properly.
## Release 1.2.0 (2016-11-04)
### Added
- #20: Added MustParse function for versions (thanks @adamreese)
- #15: Added increment methods on versions (thanks @mh-cbon)
### Fixed
- Issue #21: Per the SemVer spec (section 9) a pre-release is unstable and
might not satisfy the intended compatibility. The change here ignores pre-releases
on constraint checks (e.g., ~ or ^) when a pre-release is not part of the
constraint. For example, `^1.2.3` will ignore pre-releases while
`^1.2.3-alpha` will include them.

# SemVer
The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
* Parse semantic versions
* Sort semantic versions
* Check if a semantic version fits within a set of constraints
* Optionally work with a `v` prefix
[![Stability:
Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
[![](https://github.com/Masterminds/semver/workflows/Tests/badge.svg)](https://github.com/Masterminds/semver/actions)
[![GoDoc](https://img.shields.io/static/v1?label=godoc&message=reference&color=blue)](https://pkg.go.dev/github.com/Masterminds/semver/v3)
[![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
If you are looking for a command line tool for version comparisons please see
[vert](https://github.com/Masterminds/vert) which uses this library.
## Package Versions
There are three major versions fo the `semver` package.
* 3.x.x is the new stable and active version. This version is focused on constraint
compatibility for range handling in other tools from other languages. It has
a similar API to the v1 releases. The development of this version is on the master
branch. The documentation for this version is below.
* 2.x was developed primarily for [dep](https://github.com/golang/dep). There are
no tagged releases and the development was performed by [@sdboyer](https://github.com/sdboyer).
There are API breaking changes from v1. This version lives on the [2.x branch](https://github.com/Masterminds/semver/tree/2.x).
* 1.x.x is the most widely used version with numerous tagged releases. This is the
previous stable and is still maintained for bug fixes. The development, to fix
bugs, occurs on the release-1 branch. You can read the documentation [here](https://github.com/Masterminds/semver/blob/release-1/README.md).
## Parsing Semantic Versions
There are two functions that can parse semantic versions. 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"
}
```

/*
Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
Specifically it provides the ability to:
* Parse semantic versions
* Sort semantic versions
* Check if a semantic version fits within a set of constraints
* Optionally work with a `v` prefix
Parsing Semantic Versions
There are two functions that can parse semantic versions. 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. 1.2) 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 optional error can be returned if there is an issue
parsing the version. For example,
v, err := semver.NewVersion("1.2.3-beta.1+b345")
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. For more details please see the documentation
at https://godoc.org/github.com/Masterminds/semver.
Sorting Semantic Versions
A set of versions can be sorted using the `sort` package from the standard library.
For example,
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 and Comparing Versions
There are two methods for comparing versions. One uses comparison methods on
`Version` instances and the other is using 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 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. 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,
c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
if err != nil {
// Handle constraint not being parseable.
}
v, _ := 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"
}

# Sprig: Template functions for Go templates
[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
[![Build Status](https://travis-ci.org/Masterminds/sprig.svg?branch=master)](https://travis-ci.org/Masterminds/sprig)
The Go language comes with a [built-in template
language](http://golang.org/pkg/text/template/), but not
very many template functions. This library provides a group of commonly
used template functions.
It is inspired by the template functions found in
[Twig](http://twig.sensiolabs.org/documentation) and also in various
JavaScript libraries, such as [underscore.js](http://underscorejs.org/).
## Usage
Template developers can read the [Sprig function documentation](http://masterminds.github.io/sprig/) to
learn about the >100 template functions available.
For Go developers wishing to include Sprig as a library in their programs,
API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig), but
read on for standard usage.
### Load the Sprig library
To load the Sprig `FuncMap`:
```go
import (
"github.com/Masterminds/sprig"
"html/template"
)
// This example illustrates that the FuncMap *must* be set before the
// templates themselves are loaded.
tpl := template.Must(
template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
)
```
### Call the functions inside of templates
By convention, all functions are lowercase. This seems to follow the Go
idiom for template functions (as opposed to template methods, which are
TitleCase).
Example:
```
{{ "hello!" | upper | repeat 5 }}
```
Produces:
```
HELLO!HELLO!HELLO!HELLO!HELLO!
```
## Principles:
The following principles were used in deciding on which functions to add, and
determining how to implement them.
- Template functions should be used to build layout. Therefore, the following
types of operations are within the domain of template functions:
- Formatting
- Layout
- Simple type conversions
- Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
- Template functions should not return errors unless there is no way to print
a sensible value. For example, converting a string to an integer should not
produce an error if conversion fails. Instead, it should display a default
value that can be displayed.
- Simple math is necessary for grid layouts, pagers, and so on. Complex math
(anything other than arithmetic) should be done outside of templates.
- Template functions only deal with the data passed into them. They never retrieve
data from a source.
- Finally, do not override core Go template functions.

### Fixed
## Release 2.19.0 (2019-03-02)
IMPORTANT: This release reverts a change from 2.18.0
In the previous release (2.18), we prematurely merged a partial change to the crypto functions that led to creating two sets of crypto functions (I blame @technosophos -- since that's me). This release rolls back that change, and does what was originally intended: It alters the existing crypto functions to use secure random.
We debated whether this classifies as a change worthy of major revision, but given the proximity to the last release, we have decided that treating 2.18 as a faulty release is the correct course of action. We apologize for any inconvenience.
### Changed
- Fix substr panic 35fb796 (Alexey igrychev)
- Remove extra period 1eb7729 (Matthew Lorimor)
- Make random string functions use crypto by default 6ceff26 (Matthew Lorimor)
- README edits/fixes/suggestions 08fe136 (Lauri Apple)
## Release 2.18.0 (2019-02-12)

- Surface crypto secure random strings from goutils fe1de12 (Matthew Lorimor)

- Fix substr var names and comments d581f80 (Dean Coakley)
- Fix substr documentation 2737203 (Dean Coakley)
## Release 2.17.1 (2019-01-03)

- add now takes varargs
- biggest now takes varargs

# Sprig: Template functions for Go templates
[![GoDoc](https://img.shields.io/static/v1?label=godoc&message=reference&color=blue)](https://pkg.go.dev/github.com/Masterminds/sprig/v3)
[![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/sprig)](https://goreportcard.com/report/github.com/Masterminds/sprig)
[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
[![](https://github.com/Masterminds/sprig/workflows/Tests/badge.svg)](https://github.com/Masterminds/sprig/actions)
The Go language comes with a [built-in template
language](http://golang.org/pkg/text/template/), but not
very many template functions. Sprig is a library that provides more than 100 commonly
used template functions.
It is inspired by the template functions found in
[Twig](http://twig.sensiolabs.org/documentation) and in various
JavaScript libraries, such as [underscore.js](http://underscorejs.org/).
## IMPORTANT NOTES
Sprig leverages [mergo](https://github.com/imdario/mergo) to handle merges. In
its v0.3.9 release there was a behavior change that impacts merging template
functions in sprig. It is currently recommended to use v0.3.8 of that package.
Using v0.3.9 will cause sprig tests to fail. The issue in mergo is tracked at
https://github.com/imdario/mergo/issues/139.
## Package Versions
There are two active major versions of the `sprig` package.
* v3 is currently stable release series on the `master` branch. The Go API should
remain compatible with v2, the current stable version. Behavior change behind
some functions is the reason for the new major version.
* v2 is the previous stable release series. It has been more than three years since
the initial release of v2. You can read the documentation and see the code
on the [release-2](https://github.com/Masterminds/sprig/tree/release-2) branch.
Bug fixes to this major version will continue for some time.
## Usage
**Template developers**: Please use Sprig's [function documentation](http://masterminds.github.io/sprig/) for
detailed instructions and code snippets for the >100 template functions available.
**Go developers**: If you'd like to include Sprig as a library in your program,
our API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig).
For standard usage, read on.
### Load the Sprig library
To load the Sprig `FuncMap`:
```go
import (
"github.com/Masterminds/sprig"
"html/template"
)
// This example illustrates that the FuncMap *must* be set before the
// templates themselves are loaded.
tpl := template.Must(
template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
)
```
### Calling the functions inside of templates
By convention, all functions are lowercase. This seems to follow the Go
idiom for template functions (as opposed to template methods, which are
TitleCase). For example, this:
```
{{ "hello!" | upper | repeat 5 }}
```

## Principles Driving Our Function Selection
We followed these principles to decide which functions to add and how to implement them:
- Use template functions to build layout. The following
types of operations are within the domain of template functions:
- Formatting
- Layout
- Simple type conversions
- Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
- Template functions should not return errors unless there is no way to print
a sensible value. For example, converting a string to an integer should not
produce an error if conversion fails. Instead, it should display a default
value.
- Simple math is necessary for grid layouts, pagers, and so on. Complex math
(anything other than arithmetic) should be done outside of templates.
- Template functions only deal with the data passed into them. They never retrieve
data from a source.
- Finally, do not override core Go template functions.

# copystructure
copystructure is a Go library for deep copying values in Go.
This allows you to copy Go values that may contain reference values
such as maps, slices, or pointers, and copy their data as well instead
of just their references.
## Installation
Standard `go get`:
```
$ go get github.com/mitchellh/copystructure
```
## Usage & Example
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/copystructure).
The `Copy` function has examples associated with it there.

# reflectwalk
reflectwalk is a Go library for "walking" a value in Go using reflection,
in the same way a directory tree can be "walked" on the filesystem. Walking
a complex structure can allow you to do manipulations on unknown structures
such as those decoded from JSON.
