semver for golang [![Build Status](https://travis-ci.org/blang/semver.svg?branch=master)](https://travis-ci.org/blang/semver) [![GoDoc](https://godoc.org/github.com/blang/semver?status.png)](https://godoc.org/github.com/blang/semver) [![Coverage Status](https://img.shields.io/coveralls/blang/semver.svg)](https://coveralls.io/r/blang/semver?branch=master)
======
semver is a [Semantic Versioning](http://semver.org/) library written in golang. It fully covers spec version `2.0.0`.
Usage
-----
```bash
$ go get github.com/blang/semver
```
Note: Always vendor your dependencies or fix on a specific version tag.
```go
import github.com/blang/semver
v1, err := semver.Make("1.0.0-beta")
v2, err := semver.Make("2.0.0-beta")
v1.Compare(v2)
```
Also check the [GoDocs](http://godoc.org/github.com/blang/semver).
Why should I use this lib?
-----
- Fully spec compatible
- No reflection
- No regex
- Fully tested (Coverage >99%)
- Readable parsing/validation errors
- Fast (See [Benchmarks](#benchmarks))
- Only Stdlib
- Uses values instead of pointers
- Many features, see below
Features
-----
- Parsing and validation at all levels
- Comparator-like comparisons
- Compare Helper Methods
- InPlace manipulation
- Ranges `>=1.0.0 <2.0.0 || >=3.0.0 !3.0.1-beta.1`
- Wildcards `>=1.x`, `<=2.5.x`
- Sortable (implements sort.Interface)
- database/sql compatible (sql.Scanner/Valuer)
- encoding/json compatible (json.Marshaler/Unmarshaler)
Ranges
------
A `Range` is a set of conditions which specify which versions satisfy the range.
A condition is composed of an operator and a version. The supported operators are:
- `<1.0.0` Less than `1.0.0`
- `<=1.0.0` Less than or equal to `1.0.0`
- `>1.0.0` Greater than `1.0.0`
- `>=1.0.0` Greater than or equal to `1.0.0`
- `1.0.0`, `=1.0.0`, `==1.0.0` Equal to `1.0.0`
- `!1.0.0`, `!=1.0.0` Not equal to `1.0.0`. Excludes version `1.0.0`.
Note that spaces between the operator and the version will be gracefully tolerated.
A `Range` can link multiple `Ranges` separated by space:
Ranges can be linked by logical AND:
- `>1.0.0 <2.0.0` would match between both ranges, so `1.1.1` and `1.8.7` but not `1.0.0` or `2.0.0`
- `>1.0.0 <3.0.0 !2.0.3-beta.2` would match every version between `1.0.0` and `3.0.0` except `2.0.3-beta.2`
Ranges can also be linked by logical OR:
- `<2.0.0 || >=3.0.0` would match `1.x.x` and `3.x.x` but not `2.x.x`
AND has a higher precedence than OR. It's not possible to use brackets.
Ranges can be combined by both AND and OR
- `>1.0.0 <2.0.0 || >3.0.0 !4.2.1` would match `1.2.3`, `1.9.9`, `3.1.1`, but not `4.2.1`, `2.1.1`
Range usage:
```
v, err := semver.Parse("1.2.3")
range, err := semver.ParseRange(">1.0.0 <2.0.0 || >=3.0.0")
if range(v) {
//valid
}
```
Example
-----
Have a look at full examples in [examples/main.go](examples/main.go)
```go
import github.com/blang/semver
v, err := semver.Make("0.0.1-alpha.preview+123.github")
fmt.Printf("Major: %d\n", v.Major)
fmt.Printf("Minor: %d\n", v.Minor)
fmt.Printf("Patch: %d\n", v.Patch)
fmt.Printf("Pre: %s\n", v.Pre)
fmt.Printf("Build: %s\n", v.Build)
// Prerelease versions array
if len(v.Pre) > 0 {
fmt.Println("Prerelease versions:")
for i, pre := range v.Pre {
fmt.Printf("%d: %q\n", i, pre)
}
}
// Build meta data array
if len(v.Build) > 0 {
fmt.Println("Build meta data:")
for i, build := range v.Build {
fmt.Printf("%d: %q\n", i, build)
}
}
v001, err := semver.Make("0.0.1")
// Compare using helpers: v.GT(v2), v.LT, v.GTE, v.LTE
v001.GT(v) == true
v.LT(v001) == true
v.GTE(v) == true
v.LTE(v) == true
// Or use v.Compare(v2) for comparisons (-1, 0, 1):
v001.Compare(v) == 1
v.Compare(v001) == -1
v.Compare(v) == 0
// Manipulate Version in place:
v.Pre[0], err = semver.NewPRVersion("beta")
if err != nil {
fmt.Printf("Error parsing pre release version: %q", err)
}
fmt.Println("\nValidate versions:")
v.Build[0] = "?"
err = v.Validate()
if err != nil {
fmt.Printf("Validation failed: %s\n", err)
}

Motivation
-----
I simply couldn't find any lib supporting the full spec. Others were just wrong or used reflection and regex which i don't like.
Contribution
-----
Feel free to make a pull request. For bigger changes create a issue first to discuss about it.

# color [![](https://github.com/fatih/color/workflows/build/badge.svg)](https://github.com/fatih/color/actions) [![PkgGoDev](https://pkg.go.dev/badge/github.com/fatih/color)](https://pkg.go.dev/github.com/fatih/color)
Color lets you use colorized outputs in terms of [ANSI Escape
Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It
has support for Windows too! The API can be used in several ways, pick one that
suits you.
![Color](https://user-images.githubusercontent.com/438920/96832689-03b3e000-13f4-11eb-9803-46f4c4de3406.jpg)
## Install
```bash
go get github.com/fatih/color
```
## Examples
### Standard colors
```go
// Print with default helper functions
color.Cyan("Prints text in cyan.")
// A newline will be appended automatically
color.Blue("Prints %s in blue.", "text")
// These are using the default foreground colors
color.Red("We have red")
color.Magenta("And many others ..")
```
### Mix and reuse colors
```go
// Create a new color object
c := color.New(color.FgCyan).Add(color.Underline)
c.Println("Prints cyan text with an underline.")
// Or just add them to New()
d := color.New(color.FgCyan, color.Bold)
d.Printf("This prints bold cyan %s\n", "too!.")
// Mix up foreground and background colors, create new mixes!
red := color.New(color.FgRed)
boldRed := red.Add(color.Bold)
boldRed.Println("This will print text in bold red.")
whiteBackground := red.Add(color.BgWhite)
whiteBackground.Println("Red text with white background.")
```
### Use your own output (io.Writer)
```go
// Use your own io.Writer output
color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
blue := color.New(color.FgBlue)
blue.Fprint(writer, "This will print text in blue.")
```
### Custom print functions (PrintFunc)
```go
// Create a custom print function for convenience
red := color.New(color.FgRed).PrintfFunc()
red("Warning")
red("Error: %s", err)
// Mix up multiple attributes
notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
notice("Don't forget this...")
```
### Custom fprint functions (FprintFunc)
```go
blue := color.New(color.FgBlue).FprintfFunc()
blue(myWriter, "important notice: %s", stars)
// Mix up with multiple attributes
success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
success(myWriter, "Don't forget this...")
```
### Insert into noncolor strings (SprintFunc)
```go
// Create SprintXxx functions to mix strings with other non-colorized strings:
yellow := color.New(color.FgYellow).SprintFunc()
red := color.New(color.FgRed).SprintFunc()
fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
fmt.Printf("This %s rocks!\n", info("package"))
// Use helper functions
fmt.Println("This", color.RedString("warning"), "should be not neglected.")
fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
// Windows supported too! Just don't forget to change the output to color.Output
fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
```
### Plug into existing code
```go
// Use handy standard colors
color.Set(color.FgYellow)
fmt.Println("Existing text will now be in yellow")
fmt.Printf("This one %s\n", "too")
color.Unset() // Don't forget to unset
// You can mix up parameters
color.Set(color.FgMagenta, color.Bold)
defer color.Unset() // Use it in your function
fmt.Println("All text will now be bold magenta.")
```
### Disable/Enable color
There might be a case where you want to explicitly disable/enable color output. the
`go-isatty` package will automatically disable color output for non-tty output streams
(for example if the output were piped directly to `less`).
The `color` package also disables color output if the [`NO_COLOR`](https://no-color.org) environment
variable is set to a non-empty string.
`Color` has support to disable/enable colors programmatically both globally and
for single color definitions. For example suppose you have a CLI app and a
`-no-color` bool flag. You can easily disable the color output with:
```go
var flagNoColor = flag.Bool("no-color", false, "Disable color output")
if *flagNoColor {
color.NoColor = true // disables colorized output
}
```
It also has support for single color definitions (local). You can
disable/enable color output on the fly:
```go
c := color.New(color.FgCyan)
c.Println("Prints cyan text")
c.DisableColor()
c.Println("This is printed without any color")
c.EnableColor()
c.Println("This prints again cyan...")
```
## GitHub Actions
To output color in GitHub Actions (or other CI systems that support ANSI colors), make sure to set `color.NoColor = false` so that it bypasses the check for non-tty output streams.
## Todo
* Save/Return previous values
* Evaluate fmt.Formatter interface

/*
Package color is an ANSI color package to output colorized or SGR defined
output to the standard output. The API can be used in several way, pick one
that suits you.
Use simple and default helper functions with predefined foreground colors:
color.Cyan("Prints text in cyan.")
// a newline will be appended automatically
color.Blue("Prints %s in blue.", "text")
// More default foreground colors..
color.Red("We have red")
color.Yellow("Yellow color too!")
color.Magenta("And many others ..")
// Hi-intensity colors
color.HiGreen("Bright green color.")
color.HiBlack("Bright black means gray..")
color.HiWhite("Shiny white color!")
However, there are times when custom color mixes are required. Below are some
examples to create custom color objects and use the print functions of each
separate color object.
// Create a new color object
c := color.New(color.FgCyan).Add(color.Underline)
c.Println("Prints cyan text with an underline.")
// Or just add them to New()
d := color.New(color.FgCyan, color.Bold)
d.Printf("This prints bold cyan %s\n", "too!.")
// Mix up foreground and background colors, create new mixes!
red := color.New(color.FgRed)
boldRed := red.Add(color.Bold)
boldRed.Println("This will print text in bold red.")
whiteBackground := red.Add(color.BgWhite)
whiteBackground.Println("Red text with White background.")
// Use your own io.Writer output
color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
blue := color.New(color.FgBlue)
blue.Fprint(myWriter, "This will print text in blue.")
You can create PrintXxx functions to simplify even more:
// Create a custom print function for convenient
red := color.New(color.FgRed).PrintfFunc()
red("warning")
red("error: %s", err)
// Mix up multiple attributes
notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
notice("don't forget this...")
You can also FprintXxx functions to pass your own io.Writer:
blue := color.New(FgBlue).FprintfFunc()
blue(myWriter, "important notice: %s", stars)
// Mix up with multiple attributes
success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
success(myWriter, don't forget this...")
Or create SprintXxx functions to mix strings with other non-colorized strings:
yellow := New(FgYellow).SprintFunc()
red := New(FgRed).SprintFunc()
fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
info := New(FgWhite, BgGreen).SprintFunc()
fmt.Printf("this %s rocks!\n", info("package"))
Windows support is enabled by default. All Print functions work as intended.
However, only for color.SprintXXX functions, user should use fmt.FprintXXX and
set the output to color.Output:
fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
info := New(FgWhite, BgGreen).SprintFunc()
fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
Using with existing code is possible. Just use the Set() method to set the
standard output to the given parameters. That way a rewrite of an existing
code is not required.
// Use handy standard colors.
color.Set(color.FgYellow)
fmt.Println("Existing text will be now in Yellow")
fmt.Printf("This one %s\n", "too")
color.Unset() // don't forget to unset
// You can mix up parameters
color.Set(color.FgMagenta, color.Bold)
defer color.Unset() // use it in your function
fmt.Println("All text will be now bold magenta.")
There might be a case where you want to disable color output (for example to
pipe the standard output of your app to somewhere else). `Color` has support to
disable colors both globally and for single color definition. For example
suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
the color output with:
var flagNoColor = flag.Bool("no-color", false, "Disable color output")
if *flagNoColor {
color.NoColor = true // disables colorized output
}
You can also disable the color by setting the NO_COLOR environment variable to any value.
It also has support for single color definitions (local). You can
disable/enable color output on the fly:
c := color.New(color.FgCyan)
c.Println("Prints cyan text")
c.DisableColor()
c.Println("This is printed without any color")
c.EnableColor()
c.Println("This prints again cyan...")

# graphql-go [![Sourcegraph](https://sourcegraph.com/github.com/graph-gophers/graphql-go/-/badge.svg)](https://sourcegraph.com/github.com/graph-gophers/graphql-go?badge) [![Build Status](https://graph-gophers.semaphoreci.com/badges/graphql-go/branches/master.svg?style=shields)](https://graph-gophers.semaphoreci.com/projects/graphql-go) [![GoDoc](https://godoc.org/github.com/graph-gophers/graphql-go?status.svg)](https://godoc.org/github.com/graph-gophers/graphql-go)
<p align="center"><img src="docs/img/logo.png" width="300"></p>
The goal of this project is to provide full support of the [GraphQL draft specification](https://facebook.github.io/graphql/draft) with a set of idiomatic, easy to use Go packages.
While still under heavy development (`internal` APIs are almost certainly subject to change), this library is
safe for production use.
## Features
- minimal API
- support for `context.Context`
- support for the `OpenTracing` standard
- schema type-checking against resolvers
- resolvers are matched to the schema based on method sets (can resolve a GraphQL schema with a Go interface or Go struct).
- handles panics in resolvers
- parallel execution of resolvers
- subscriptions
- [sample WS transport](https://github.com/graph-gophers/graphql-transport-ws)
## Roadmap
We're trying out the GitHub Project feature to manage `graphql-go`'s [development roadmap](https://github.com/graph-gophers/graphql-go/projects/1).
Feedback is welcome and appreciated.
## (Some) Documentation
### Basic Sample
```go
package main
import (
"log"
"net/http"
graphql "github.com/graph-gophers/graphql-go"
"github.com/graph-gophers/graphql-go/relay"
)
type query struct{}
func (_ *query) Hello() string { return "Hello, world!" }
func main() {
s := `
type Query {
hello: String!
}
`
schema := graphql.MustParseSchema(s, &query{})
http.Handle("/query", &relay.Handler{Schema: schema})
log.Fatal(http.ListenAndServe(":8080", nil))
}
```
To test:
```sh
curl -XPOST -d '{"query": "{ hello }"}' localhost:8080/query
```
### Resolvers
A resolver must have one method or field for each field of the GraphQL type it resolves. The method or field name has to be [exported](https://golang.org/ref/spec#Exported_identifiers) and match the schema's field's name in a non-case-sensitive way.
You can use struct fields as resolvers by using `SchemaOpt: UseFieldResolvers()`. For example,
```
opts := []graphql.SchemaOpt{graphql.UseFieldResolvers()}
schema := graphql.MustParseSchema(s, &query{}, opts...)
```
When using `UseFieldResolvers` schema option, a struct field will be used *only* when:
- there is no method for a struct field
- a struct field does not implement an interface method
- a struct field does not have arguments
The method has up to two arguments:
- Optional `context.Context` argument.
- Mandatory `*struct { ... }` argument if the corresponding GraphQL field has arguments. The names of the struct fields have to be [exported](https://golang.org/ref/spec#Exported_identifiers) and have to match the names of the GraphQL arguments in a non-case-sensitive way.
The method has up to two results:
- The GraphQL field's value as determined by the resolver.
- Optional `error` result.
Example for a simple resolver method:
```go
func (r *helloWorldResolver) Hello() string {
return "Hello world!"
}
```
The following signature is also allowed:
```go
func (r *helloWorldResolver) Hello(ctx context.Context) (string, error) {
return "Hello world!", nil
}
```
### Schema Options
- `UseStringDescriptions()` enables the usage of double quoted and triple quoted. When this is not enabled, comments are parsed as descriptions instead.
- `UseFieldResolvers()` specifies whether to use struct field resolvers.
- `MaxDepth(n int)` specifies the maximum field nesting depth in a query. The default is 0 which disables max depth checking.
- `MaxParallelism(n int)` specifies the maximum number of resolvers per request allowed to run in parallel. The default is 10.
- `Tracer(tracer trace.Tracer)` is used to trace queries and fields. It defaults to `trace.OpenTracingTracer`.
- `ValidationTracer(tracer trace.ValidationTracer)` is used to trace validation errors. It defaults to `trace.NoopValidationTracer`.
- `Logger(logger log.Logger)` is used to log panics during query execution. It defaults to `exec.DefaultLogger`.
- `PanicHandler(panicHandler errors.PanicHandler)` is used to transform panics into errors during query execution. It defaults to `errors.DefaultPanicHandler`.
- `DisableIntrospection()` disables introspection queries.
### Custom Errors
Errors returned by resolvers can include custom extensions by implementing the `ResolverError` interface:
```go
type ResolverError interface {
error
Extensions() map[string]interface{}
}
```
Example of a simple custom error:
```go
type droidNotFoundError struct {
Code string `json:"code"`
Message string `json:"message"`
}
func (e droidNotFoundError) Error() string {
return fmt.Sprintf("error [%s]: %s", e.Code, e.Message)
}
func (e droidNotFoundError) Extensions() map[string]interface{} {
return map[string]interface{}{
"code": e.Code,
"message": e.Message,
}
}
```
Which could produce a GraphQL error such as:
```go
{
"errors": [
{
"message": "error [NotFound]: This is not the droid you are looking for",
"path": [
"droid"
],
"extensions": {
"code": "NotFound",
"message": "This is not the droid you are looking for"
}
}
],
"data": null
}
```

#
# Depending on the kind of a type, certain fields describe information about that
# type. Scalar types provide no information beyond a name and description, while
# Enum types provide their values. Object and Interface types provide the fields
# they describe. Abstract types, Union and Interface, provide the Object types
# possible at runtime. List and NonNull types compose other types.
