# Color [![GoDoc](https://godoc.org/github.com/fatih/color?status.svg)](https://godoc.org/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://i.imgur.com/c1JI0lA.png)
## 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(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`)
`Color` has support to disable/enable colors 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...")
```
## 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 where 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
}
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...")

# structtag [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/fatih/structtag)
structtag provides an easy way of parsing and manipulating struct tag fields.
Please vendor the library as it might change in future versions.
# Install
```bash
go get github.com/fatih/structtag
```
# Example
```go
package main
import (
"fmt"
"reflect"
"sort"
"github.com/fatih/structtag"
)
func main() {
type t struct {
t string `json:"foo,omitempty,string" xml:"foo"`
}
// get field tag
tag := reflect.TypeOf(t{}).Field(0).Tag
// ... and start using structtag by parsing the tag
tags, err := structtag.Parse(string(tag))
if err != nil {
panic(err)
}
// iterate over all tags
for _, t := range tags.Tags() {
fmt.Printf("tag: %+v\n", t)
}
// get a single tag
jsonTag, err := tags.Get("json")
if err != nil {
panic(err)
}
fmt.Println(jsonTag) // Output: json:"foo,omitempty,string"
fmt.Println(jsonTag.Key) // Output: json
fmt.Println(jsonTag.Name) // Output: foo
fmt.Println(jsonTag.Options) // Output: [omitempty string]
// change existing tag
jsonTag.Name = "foo_bar"
jsonTag.Options = nil
tags.Set(jsonTag)
// add new tag
tags.Set(&structtag.Tag{
Key: "hcl",
Name: "foo",
Options: []string{"squash"},
})
// print the tags
fmt.Println(tags) // Output: json:"foo_bar" xml:"foo" hcl:"foo,squash"
// sort tags according to keys
sort.Sort(tags)
fmt.Println(tags) // Output: hcl:"foo,squash" json:"foo_bar" xml:"foo"
}
```

# go-colorable
[![Godoc Reference](https://godoc.org/github.com/mattn/go-colorable?status.svg)](http://godoc.org/github.com/mattn/go-colorable)
[![Build Status](https://travis-ci.org/mattn/go-colorable.svg?branch=master)](https://travis-ci.org/mattn/go-colorable)
[![Coverage Status](https://coveralls.io/repos/github/mattn/go-colorable/badge.svg?branch=master)](https://coveralls.io/github/mattn/go-colorable?branch=master)
[![Go Report Card](https://goreportcard.com/badge/mattn/go-colorable)](https://goreportcard.com/report/mattn/go-colorable)
Colorable writer for windows.
For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
This package is possible to handle escape sequence for ansi color on windows.
## Too Bad!
![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/bad.png)
## So Good!
![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/good.png)
## Usage
```go
logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
logrus.SetOutput(colorable.NewColorableStdout())
logrus.Info("succeeded")
logrus.Warn("not correct")
logrus.Error("something error")
logrus.Fatal("panic")
```
You can compile above code on non-windows OSs.
## Installation
```
$ go get github.com/mattn/go-colorable

# Dots
Implements the wildcard file matching in Go used by golint, go test etc.
## Usage
```go
import "github.com/mgechev/dots"
func main() {
result, err := dots.Resolve([]string{"./fixtures/..."}, []string{"./fixtures/foo"})
for _, f := range result {
fmt.Println(f);
}
}
```
If we suppose that we have the following directory structure:
```text
├── README.md
├── fixtures
│   ├── bar
│   │   ├── bar1.go
│   │   └── bar2.go
│   ├── baz
│   │   ├── baz1.go
│   │   ├── baz2.go
│   │   └── baz3.go
│   └── foo
│   ├── foo1.go
│   ├── foo2.go
│   └── foo3.go
└── main.go
```
The result will be:
```text
fixtures/bar/bar1.go
fixtures/bar/bar2.go
fixtures/baz/baz1.go
fixtures/baz/baz2.go
fixtures/baz/baz3.go
```
`dots` supports wildcard in both - the first and the last argument of `Resolve`, which means that you can ignore files based on a wildcard:
```go
dots.Resolve([]string{"github.com/mgechev/dots"}, []string{"./..."}) // empty list
dots.Resolve([]string{"./fixtures/bar/..."}, []string{"./fixture/foo/...", "./fixtures/baz/..."}) // bar1.go, bar2.go
```
## Preserve package structure
`dots` allow you to receive a slice of slices where each nested slice represents an individual package:
```go
dots.ResolvePackages([]string{"github.com/mgechev/dots/..."}, []string{})
```
So we will get the result:
```text
[
[
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar1.go",
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar2.go"
],
[
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz1.go",
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz2.go",
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz3.go"
],
[
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo1.go",
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo2.go",
"$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo3.go"
],
[
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz1.go",
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz2.go"
],
[
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo1.go",
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo2.go"
],
[
"$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/bar/bar1.go"
]
]
```
This method is especially useful, when you want to perform type checking over given package from the result.
