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
|
||||
|
||||
[](https://masterminds.github.io/stability/active.html)
|
||||
[](https://travis-ci.org/Masterminds/semver) [](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [](https://godoc.org/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.
|
||||
|
||||
## 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
|
||||
|
||||
## Working With Pre-release Versions
|
||||
|
||||
Pre-releases, for those not familiar with them, are used for software releases
|
||||
prior to stable or generally available releases. Examples of pre-releases include
|
||||
development, alpha, beta, and release candidate releases. A pre-release may be
|
||||
a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
|
||||
order of precidence, pre-releases come before their associated releases. In this
|
||||
example `1.2.3-beta.1 < 1.2.3`.
|
||||
|
||||
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 comparator will skip pre-release versions.
|
||||
For example, `>=1.2.3` will skip pre-releases when looking at a list of releases
|
||||
while `>=1.2.3-0` will evaluate and find pre-releases.
|
||||
|
||||
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 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`
|
||||
* `^0.0.1` is equivalent to `>= 0.0.1, < 1.0.0`
|
||||
* `^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, err := 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`

|
||||
|
||||
## 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.
|
||||

|
||||
|
||||
### Fixed
|

properly.
|
||||
|

### Fixed
|
||||
|

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

||||

||||

|
||||
|
||||
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`
|

## 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"
|
||||
}

/*
|
||||
Package complete provides a tool for bash writing bash completion in go, and bash completion for the go command line.
|
||||
|
||||
Writing bash completion scripts is a hard work. This package provides an easy way
|
||||
to create bash completion scripts for any command, and also an easy way to install/uninstall
|
||||
the completion of the command.
|
||||
|
||||
Go Command Bash Completion
|
||||
|
||||
In ./cmd/gocomplete there is an example for bash completion for the `go` command line.
|
||||
|
||||
This is an example that uses the `complete` package on the `go` command - the `complete` package
|
||||
can also be used to implement any completions, see #usage.
|
||||
|
||||
Install
|
||||
|
||||
1. Type in your shell:
|
||||
|
||||
go get -u github.com/posener/complete/gocomplete
|
||||
gocomplete -install
|
||||
|
||||
2. Restart your shell
|
||||
|
||||
Uninstall by `gocomplete -uninstall`
|
||||
|
||||
Features
|
||||
|
||||
- Complete `go` command, including sub commands and all flags.
|
||||
- Complete packages names or `.go` files when necessary.
|
||||
- Complete test names after `-run` flag.
|
||||
|
||||
Complete package
|
||||
|
||||
Supported shells:
|
||||
|
||||
- [x] bash
|
||||
- [x] zsh
|
||||
- [x] fish
|
||||
|
||||
Usage
|
||||
|
||||
Assuming you have program called `run` and you want to have bash completion
|
||||
for it, meaning, if you type `run` then space, then press the `Tab` key,
|
||||
the shell will suggest relevant complete options.
|
||||
|
||||
In that case, we will create a program called `runcomplete`, a go program,
|
||||
with a `func main()` and so, that will make the completion of the `run`
|
||||
program. Once the `runcomplete` will be in a binary form, we could
|
||||
`runcomplete -install` and that will add to our shell all the bash completion
|
||||
options for `run`.
|
||||
|
||||
So here it is:
|
||||
|
||||
import "github.com/posener/complete"
|
||||
|
||||
func main() {
|
||||
|
||||
// create a Command object, that represents the command we want
|
||||
// to complete.
|
||||
run := complete.Command{
|
||||
|
||||
// Sub defines a list of sub commands of the program,
|
||||
// this is recursive, since every command is of type command also.
|
||||
Sub: complete.Commands{
|
||||
|
||||
// add a build sub command
|
||||
"build": complete.Command {
|
||||
|
||||
// define flags of the build sub command
|
||||
Flags: complete.Flags{
|
||||
// build sub command has a flag '-cpus', which
|
||||
// expects number of cpus after it. in that case
|
||||
// anything could complete this flag.
|
||||
"-cpus": complete.PredictAnything,
|
||||
},
|
||||
},
|
||||
},
|
||||
|
||||
// define flags of the 'run' main command
|
||||
Flags: complete.Flags{
|
||||
// a flag -o, which expects a file ending with .out after
|
||||
// it, the tab completion will auto complete for files matching
|
||||
// the given pattern.
|
||||
"-o": complete.PredictFiles("*.out"),
|
||||
},
|
||||
|
||||
// define global flags of the 'run' main command
|
||||
// those will show up also when a sub command was entered in the
|
||||
// command line
|
||||
GlobalFlags: complete.Flags{
|
||||
|
||||
// a flag '-h' which does not expects anything after it
|
||||
"-h": complete.PredictNothing,
|
||||
},
|
||||
}
|
||||
|
||||
// run the command completion, as part of the main() function.
|
||||
// this triggers the autocompletion when needed.
|
||||
// name must be exactly as the binary that we want to complete.
|
||||
complete.New("run", run).Run()
|
||||
}
|
||||
|
||||
Self completing program
|
||||
|
||||
In case that the program that we want to complete is written in go we
|
||||
can make it self completing.
|
||||
Here is an example: ./example/self/main.go .

|
||||
|
||||
Arbitrary-precision fixed-point decimal numbers in go.
|
||||
|
||||
_Note:_ Decimal library can "only" represent numbers with a maximum of 2^31 digits after the decimal point.
|
||||
|
||||
## Features
|
||||
|
||||
* The zero-value is 0, and is safe to use without initialization
|
||||
* Addition, subtraction, multiplication with no loss of precision
|
||||
* Division with specified precision
|
||||
* Database/sql serialization/deserialization
|
||||
* JSON and XML serialization/deserialization
|
||||
|
||||
## Install
|
||||
|
||||
Run `go get github.com/shopspring/decimal`
|
||||
|
||||
## Requirements
|
||||
|
||||
Decimal library requires Go version `>=1.7`
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"github.com/shopspring/decimal"
|
||||
)
|
||||
|
||||
func main() {
|
||||
price, err := decimal.NewFromString("136.02")
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
quantity := decimal.NewFromInt(3)
|
||||
|
||||
fee, _ := decimal.NewFromString(".035")
|
||||
taxRate, _ := decimal.NewFromString(".08875")
|
||||
|
||||
subtotal := price.Mul(quantity)
|
||||
|
||||
preTax := subtotal.Mul(fee.Add(decimal.NewFromFloat(1)))
|
||||
|
||||
total := preTax.Mul(taxRate.Add(decimal.NewFromFloat(1)))
|
||||
|
||||
fmt.Println("Subtotal:", subtotal) // Subtotal: 408.06
|
||||
fmt.Println("Pre-tax:", preTax) // Pre-tax: 422.3421
|
||||
fmt.Println("Taxes:", total.Sub(preTax)) // Taxes: 37.482861375
|
||||
fmt.Println("Total:", total) // Total: 459.824961375
|
||||
fmt.Println("Tax rate:", total.Sub(preTax).Div(preTax)) // Tax rate: 0.08875
|
||||
}

## FAQ
|
||||
|
||||
#### Why don't you just use float64?
|
||||
|
||||
Because float64 (or any binary floating point type, actually) can't represent
|
||||
numbers such as `0.1` exactly.
|
||||
|
||||
Consider this code: http://play.golang.org/p/TQBd4yJe6B You might expect that
|
||||
it prints out `10`, but it actually prints `9.999999999999831`. Over time,
|
||||
these small errors can really add up!
|
||||
|
||||
#### Why don't you just use big.Rat?
|
||||
|
||||
big.Rat is fine for representing rational numbers, but Decimal is better for
|
||||
representing money. Why? Here's a (contrived) example:
|
||||
|
||||
Let's say you use big.Rat, and you have two numbers, x and y, both
|
||||
representing 1/3, and you have `z = 1 - x - y = 1/3`. If you print each one
|
||||
out, the string output has to stop somewhere (let's say it stops at 3 decimal
|
||||
digits, for simplicity), so you'll get 0.333, 0.333, and 0.333. But where did
|
||||
the other 0.001 go?
|
||||
|
||||
Here's the above example as code: http://play.golang.org/p/lCZZs0w9KE
|
||||
|
||||
With Decimal, the strings being printed out represent the number exactly. So,
|
||||
if you have `x = y = 1/3` (with precision 3), they will actually be equal to
|
||||
0.333, and when you do `z = 1 - x - y`, `z` will be equal to .334. No money is
|
||||
unaccounted for!
|
||||
|
||||
You still have to be careful. If you want to split a number `N` 3 ways, you
|
||||
can't just send `N/3` to three different people. You have to pick one to send
|
||||
`N - (2/3*N)` to. That person will receive the fraction of a penny remainder.
|
||||
|
||||
But, it is much easier to be careful with Decimal than with big.Rat.
|
||||
|
||||
#### Why isn't the API similar to big.Int's?
|
||||
|
||||
big.Int's API is built to reduce the number of memory allocations for maximal
|
||||
performance. This makes sense for its use-case, but the trade-off is that the
|
||||
API is awkward and easy to misuse.
|
||||
|
||||
For example, to add two big.Ints, you do: `z := new(big.Int).Add(x, y)`. A
|
||||
developer unfamiliar with this API might try to do `z := a.Add(a, b)`. This
|
||||
modifies `a` and sets `z` as an alias for `a`, which they might not expect. It
|
||||
also modifies any other aliases to `a`.
|
||||
|
||||
Here's an example of the subtle bugs you can introduce with big.Int's API:
|
||||
https://play.golang.org/p/x2R_78pa8r
|
||||
|
||||
In contrast, it's difficult to make such mistakes with decimal. Decimals
|
||||
behave like other go numbers types: even though `a = b` will not deep copy
|
||||
`b` into `a`, it is impossible to modify a Decimal, since all Decimal methods
|
||||
return new Decimals and do not modify the originals. The downside is that
|
||||
this causes extra allocations, so Decimal is less performant. My assumption
|
||||
is that if you're using Decimals, you probably care more about correctness
|
||||
than performance.
