# go-ansiterm
This is a cross platform Ansi Terminal Emulation library. It reads a stream of Ansi characters and produces the appropriate function calls. The results of the function calls are platform dependent.
For example the parser might receive "ESC, [, A" as a stream of three characters. This is the code for Cursor Up (http://www.vt100.net/docs/vt510-rm/CUU). The parser then calls the cursor up function (CUU()) on an event handler. The event handler determines what platform specific work must be done to cause the cursor to move up one position.
The parser (parser.go) is a partial implementation of this state machine (http://vt100.net/emu/vt500_parser.png). There are also two event handler implementations, one for tests (test_event_handler.go) to validate that the expected events are being produced and called, the other is a Windows implementation (winterm/win_event_handler.go).
See parser_test.go for examples exercising the state machine and generating appropriate function calls.

TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
reflection interface similar to Go's standard library `json` and `xml`
packages.
Compatible with TOML version [v1.0.0](https://toml.io/en/v1.0.0).
Documentation: https://godocs.io/github.com/BurntSushi/toml
See the [releases page](https://github.com/BurntSushi/toml/releases) for a
changelog; this information is also in the git tag annotations (e.g. `git show
v0.4.0`).
This library requires Go 1.13 or newer; install it with:
% go get github.com/BurntSushi/toml@latest
It also comes with a TOML validator CLI tool:
% go install github.com/BurntSushi/toml/cmd/tomlv@latest
% tomlv some-toml-file.toml
### Testing
This package passes all tests in [toml-test] for both the decoder and the
encoder.
[toml-test]: https://github.com/BurntSushi/toml-test
### Examples
This package works similar to how the Go standard library handles XML and JSON.
Namely, data is loaded into Go values via reflection.
For the simplest example, consider some TOML file as just a list of keys and
values:
```toml
Age = 25
Cats = [ "Cauchy", "Plato" ]
Pi = 3.14
Perfection = [ 6, 28, 496, 8128 ]
DOB = 1987-07-05T05:45:00Z
```
Which could be defined in Go as:
```go
type Config struct {
Age int
Cats []string
Pi float64
Perfection []int
DOB time.Time // requires `import time`
}
```
And then decoded with:
```go
var conf Config
_, err := toml.Decode(tomlData, &conf)
// handle error
```
You can also use struct tags if your struct field name doesn't map to a TOML
key value directly:
```toml
some_key_NAME = "wat"
```
```go
type TOML struct {
ObscureKey string `toml:"some_key_NAME"`
}
```
Beware that like other most other decoders **only exported fields** are
considered when encoding and decoding; private fields are silently ignored.
### Using the `Marshaler` and `encoding.TextUnmarshaler` interfaces
Here's an example that automatically parses duration strings into
`time.Duration` values:
```toml
[[song]]
name = "Thunder Road"
duration = "4m49s"
[[song]]
name = "Stairway to Heaven"
duration = "8m03s"
```
Which can be decoded with:
```go
type song struct {
Name string
Duration duration
}
type songs struct {
Song []song
}
var favorites songs
if _, err := toml.Decode(blob, &favorites); err != nil {
log.Fatal(err)
}
for _, s := range favorites.Song {
fmt.Printf("%s (%s)\n", s.Name, s.Duration)
}
```
And you'll also need a `duration` type that satisfies the
`encoding.TextUnmarshaler` interface:
```go
type duration struct {
time.Duration
}
func (d *duration) UnmarshalText(text []byte) error {
var err error
d.Duration, err = time.ParseDuration(string(text))
return err
}
```
To target TOML specifically you can implement `UnmarshalTOML` TOML interface in
a similar way.
### More complex usage
Here's an example of how to load the example from the official spec page:
```toml
# This is a TOML document. Boom.
title = "TOML Example"
[owner]
name = "Tom Preston-Werner"
organization = "GitHub"
bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
dob = 1979-05-27T07:32:00Z # First class dates? Why not?
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
connection_max = 5000
enabled = true
[servers]
# You can indent as you please. Tabs or spaces. TOML don't care.
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"
[clients]
data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
# Line breaks are OK when inside arrays
hosts = [
"alpha",
"omega"
]
```
And the corresponding Go types are:
```go
type tomlConfig struct {
Title string
Owner ownerInfo
DB database `toml:"database"`
Servers map[string]server
Clients clients
}
type ownerInfo struct {
Name string
Org string `toml:"organization"`
Bio string
DOB time.Time
}
type database struct {
Server string
Ports []int
ConnMax int `toml:"connection_max"`
Enabled bool
}
type server struct {
IP string
DC string
}
type clients struct {
Data [][]interface{}
Hosts []string
}
```
Note that a case insensitive match will be tried if an exact match can't be
found.
A working example of the above can be found in `_example/example.{go,toml}`.

Package toml implements decoding and encoding of TOML files.
This package supports TOML v1.0.0, as listed on https://toml.io
There is also support for delaying decoding with the Primitive type, and
querying the set of keys in a TOML document with the MetaData type.
The github.com/BurntSushi/toml/cmd/tomlv package implements a TOML validator,
and can be used to verify if TOML document is valid. It can also be used to
print the type of each key.

A '\' inside a "-delimited string is interpreted as an escape character.
The following escape sequences are supported:
\b, \t, \n, \f, \r, \", \\, \uXXXX, and \UXXXXXXXX
To prevent a '\' from being recognized as an escape character, use either:
- a ' or '''-delimited string; escape characters aren't processed in them; or
- write two backslashes to get a single backslash: '\\'.
If you're trying to add a Windows path (e.g. "C:\Users\martin") then using '/'

GoUtils
===========
[![Stability: Maintenance](https://masterminds.github.io/stability/maintenance.svg)](https://masterminds.github.io/stability/maintenance.html)
[![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils) [![Build Status](https://travis-ci.org/Masterminds/goutils.svg?branch=master)](https://travis-ci.org/Masterminds/goutils) [![Build status](https://ci.appveyor.com/api/projects/status/sc2b1ew0m7f0aiju?svg=true)](https://ci.appveyor.com/project/mattfarina/goutils)
GoUtils provides users with utility functions to manipulate strings in various ways. It is a Go implementation of some
string manipulation libraries of Java Apache Commons. GoUtils includes the following Java Apache Commons classes:
* WordUtils
* RandomStringUtils
* StringUtils (partial implementation)
## Installation
If you have Go set up on your system, from the GOPATH directory within the command line/terminal, enter this:
go get github.com/Masterminds/goutils
If you do not have Go set up on your system, please follow the [Go installation directions from the documenation](http://golang.org/doc/install), and then follow the instructions above to install GoUtils.
## Documentation
GoUtils doc is available here: [![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils)
## Usage
The code snippets below show examples of how to use GoUtils. Some functions return errors while others do not. The first instance below, which does not return an error, is the `Initials` function (located within the `wordutils.go` file).
package main
import (
"fmt"
"github.com/Masterminds/goutils"
)
func main() {
// EXAMPLE 1: A goutils function which returns no errors
fmt.Println (goutils.Initials("John Doe Foo")) // Prints out "JDF"
}
Some functions return errors mainly due to illegal arguements used as parameters. The code example below illustrates how to deal with function that returns an error. In this instance, the function is the `Random` function (located within the `randomstringutils.go` file).
package main
import (
"fmt"
"github.com/Masterminds/goutils"
)
func main() {
// EXAMPLE 2: A goutils function which returns an error
rand1, err1 := goutils.Random (-1, 0, 0, true, true)
if err1 != nil {
fmt.Println(err1) // Prints out error message because -1 was entered as the first parameter in goutils.Random(...)
} else {
fmt.Println(rand1)
}
}

## 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)
- #83: Clarify caret operator range for pre-1.0.0 dependencies (thanks @greysteil)
- #72: Adding docs comment pointing to vert for a cli
- #71: Update the docs on pre-release comparator handling
- #89: Test with new go versions (thanks @thedevsaddam)
- #87: Added $ to ValidPrerelease for better validation (thanks @jeremycarroll)
### Fixed
- #78: Fix unchecked error in example code (thanks @ravron)
- #70: Fix the handling of pre-releases and the 0.0.0 release edge case
- #97: Fixed copyright file for proper display on GitHub
- #107: Fix handling prerelease when sorting alphanum and num
- #109: Fixed where Validate sometimes returns wrong message on error
## 1.4.2 (2018-04-10)
### Changed
- #72: Updated the docs to point to vert for a console appliaction
- #71: Update the docs on pre-release comparator handling
### Fixed

## Release 1.2.1 (2016-11-28)
### Fixed
- #24: Fixed edge case issue where constraint "> 0" does not handle "0.0.1-alpha"
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.
## Release 1.1.1 (2016-06-30)
### Changed
- Issue #9: Speed up version comparison performance (thanks @sdboyer)
- Issue #8: Added benchmarks (thanks @sdboyer)
- Updated Go Report Card URL to new location
- Updated Readme to add code snippet formatting (thanks @mh-cbon)
- Updating tagging to v[SemVer] structure for compatibility with other tools.
## Release 1.1.0 (2016-03-11)
- Issue #2: Implemented validation to provide reasons a versions failed a
constraint.
## Release 1.0.1 (2015-12-31)
- Fixed #1: * constraint failing on valid versions.
## Release 1.0.0 (2015-10-20)
- Initial release

# 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"
}

### 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

## Release 2.0.0 (2016-03-29)
Because we switched from `int` to `int64` as the return value for all integer math functions, the library's major version number has been incremented.

# 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 }}
```
produces this:
```
HELLO!HELLO!HELLO!HELLO!HELLO!
```
## 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.

/*
Package sprig provides template functions for Go.
This package contains a number of utility functions for working with data
inside of Go `html/template` and `text/template` files.
To add these functions, use the `template.Funcs()` method:
t := templates.New("foo").Funcs(sprig.FuncMap())
Note that you should add the function map before you parse any template files.
In several cases, Sprig reverses the order of arguments from the way they
appear in the standard library. This is to make it easier to pipe
arguments into functions.
See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.

# go-winio [![Build Status](https://github.com/microsoft/go-winio/actions/workflows/ci.yml/badge.svg)](https://github.com/microsoft/go-winio/actions/workflows/ci.yml)
This repository contains utilities for efficiently performing Win32 IO operations in
Go. Currently, this is focused on accessing named pipes and other file handles, and
for using named pipes as a net transport.
This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
newer operating systems. This is similar to the implementation of network sockets in Go's net
package.
Please see the LICENSE file for licensing information.
