# Color [](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.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## 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

||||
|
||||

/*
|

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( | ||||
