+
+
+
+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.")
+```
+
+### 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...")
+```
+
+### 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.Printf("This", color.RedString("warning"), "should be not neglected.")
+fmt.Printf(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 color
+
+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:
+
+```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 ..")
+
+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.")
+
+
+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...")
+
+
+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 works 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...")

-Executables
-===========
+## Executables
 
 Go Ethereum comes with several wrappers/executables found in 
 [the `cmd` directory](https://github.com/ethereum/go-ethereum/tree/develop/cmd):
 
-* `geth` Ethereum CLI (ethereum command line interface client)
-* `bootnode` runs a bootstrap node for the Discovery Protocol
-* `ethtest` test tool which runs with the [tests](https://github.com/ethereum/tests) suite: 
-  `/path/to/test.json > ethtest --test BlockTests --stdin`.
-* `evm` is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas
-  10000 -price 0 -dump`. See `-h` for a detailed description.
-* `disasm` disassembles EVM code: `echo "6001" | disasm`
-* `rlpdump` prints RLP structures

-Command line options
-====================
+## Command line options
 
 `geth` can be configured via command line options, environment variables and config files.
 
 To get the options available:
 
-    geth --help
+    geth help
 
 For further details on options, see the [wiki](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options)
