# Color [![GoDoc](https://godoc.org/github.com/fatih/color?status.svg)](https://godoc.org/github.com/fatih/color) [![Build Status](https://img.shields.io/travis/fatih/color.svg?style=flat-square)](https://travis-ci.org/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
```
Note that the `vendor` folder is here for stability. Remove the folder if you
already have the dependencies in your GOPATH.
## 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...")

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

# Contributing to Go
Go is an open source project.
It is the work of hundreds of contributors. We appreciate your help!
## Filing issues
When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
1. What version of Go are you using (`go version`)?
2. What operating system and processor architecture are you using?
3. What did you do?
4. What did you expect to see?
5. What did you see instead?
General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
The gophers there will answer or ask you to file an issue if you've tripped over a bug.
## Contributing code
Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
before sending patches.
**We do not accept GitHub pull requests**
(we use [Gerrit](https://code.google.com/p/gerrit/) instead for code review).
Unless otherwise noted, the Go source files are distributed under
the BSD-style license found in the LICENSE file.

# The plan9 package provides access to the raw system call
# interface of the underlying operating system. Porting Go to
# a new architecture/operating system combination requires
# some manual effort, though there are tools that automate
# much of the process. The auto-generated files have names
# beginning with z.
#
# This script runs or (given -n) prints suggested commands to generate z files
# for the current system. Running those commands is not automatic.
# This script is documentation more than anything else.
#
# * asm_${GOOS}_${GOARCH}.s
#
# This hand-written assembly file implements system call dispatch.
# There are three entry points:
#
# func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
# func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
# func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
#
# The first and second are the standard ones; they differ only in
# how many arguments can be passed to the kernel.
# The third is for low-level use by the ForkExec wrapper;
# unlike the first two, it does not call into the scheduler to
# let it know that a system call is running.
#
# * syscall_${GOOS}.go
#
# This hand-written Go file implements system calls that need
# special handling and lists "//sys" comments giving prototypes
# for ones that can be auto-generated. Mksyscall reads those
# comments to generate the stubs.
#
# * syscall_${GOOS}_${GOARCH}.go
#
# Same as syscall_${GOOS}.go except that it contains code specific
# to ${GOOS} on one particular architecture.
#
# * types_${GOOS}.c
#
# This hand-written C file includes standard C headers and then
# creates typedef or enum names beginning with a dollar sign
# (use of $ in variable names is a gcc extension). The hardest
# part about preparing this file is figuring out which headers to
# include and which symbols need to be #defined to get the
# actual data structures that pass through to the kernel system calls.
# Some C libraries present alternate versions for binary compatibility
# and translate them on the way in and out of system calls, but
# there is almost always a #define that can get the real ones.
# See types_darwin.c and types_linux.c for examples.
#
# * zerror_${GOOS}_${GOARCH}.go
#
# This machine-generated file defines the system's error numbers,
# error strings, and signal numbers. The generator is "mkerrors.sh".
# Usually no arguments are needed, but mkerrors.sh will pass its
# arguments on to godefs.
#

// Package plan9 contains an interface to the low-level operating system

// by default, godoc will display the OS-specific documentation for the current

// system, set $GOOS and $GOARCH to the desired system. For example, if
// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
// to freebsd and $GOARCH to arm.
// The primary use of this package is inside other packages that provide a more
// portable interface to the system, such as "os", "time" and "net". Use
// those packages rather than this one if you can.
// For details of the functions and data types in this package consult
// the manuals for the appropriate operating system.

# Building `sys/unix`
The sys/unix package provides access to the raw system call interface of the
underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
Porting Go to a new architecture/OS combination or adding syscalls, types, or
constants to an existing architecture/OS pair requires some manual effort;
however, there are tools that automate much of the process.
## Build Systems
There are currently two ways we generate the necessary files. We are currently
migrating the build system to use containers so the builds are reproducible.
This is being done on an OS-by-OS basis. Please update this documentation as
components of the build system change.
### Old Build System (currently for `GOOS != "Linux" || GOARCH == "sparc64"`)
The old build system generates the Go files based on the C header files
present on your system. This means that files
for a given GOOS/GOARCH pair must be generated on a system with that OS and
architecture. This also means that the generated code can differ from system
to system, based on differences in the header files.
To avoid this, if you are using the old build system, only generate the Go
files on an installation with unmodified header files. It is also important to
keep track of which version of the OS the files were generated from (ex.
Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
and have each OS upgrade correspond to a single change.
To build the files for your current OS and architecture, make sure GOOS and
GOARCH are set correctly and run `mkall.sh`. This will generate the files for
your specific system. Running `mkall.sh -n` shows the commands that will be run.
Requirements: bash, perl, go
### New Build System (currently for `GOOS == "Linux" && GOARCH != "sparc64"`)
The new build system uses a Docker container to generate the go files directly
from source checkouts of the kernel and various system libraries. This means
that on any platform that supports Docker, all the files using the new build
system can be generated at once, and generated files will not change based on
what the person running the scripts has installed on their computer.
The OS specific files for the new build system are located in the `${GOOS}`
directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
the kernel or system library updates, modify the Dockerfile at
`${GOOS}/Dockerfile` to checkout the new release of the source.
To build all the files under the new build system, you must be on an amd64/Linux
system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
then generate all of the files for all of the GOOS/GOARCH pairs in the new build
system. Running `mkall.sh -n` shows the commands that will be run.
Requirements: bash, perl, go, docker
## Component files
This section describes the various files used in the code generation process.
It also contains instructions on how to modify these files to add a new
architecture/OS or to add additional syscalls, types, or constants. Note that
if you are using the new build system, the scripts cannot be called normally.
They must be called from within the docker container.
### asm files
The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
call dispatch. There are three entry points:
```
func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
```
The first and second are the standard ones; they differ only in how many
arguments can be passed to the kernel. The third is for low-level use by the
ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
let it know that a system call is running.
When porting Go to an new architecture/OS, this file must be implemented for
each GOOS/GOARCH pair.
### mksysnum
Mksysnum is a script located at `${GOOS}/mksysnum.pl` (or `mksysnum_${GOOS}.pl`
for the old system). This script takes in a list of header files containing the
syscall number declarations and parses them to produce the corresponding list of
Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
constants.
Adding new syscall numbers is mostly done by running the build on a sufficiently
new installation of the target OS (or updating the source checkouts for the
new build system). However, depending on the OS, you make need to update the
parsing in mksysnum.
### mksyscall.pl
The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
hand-written Go files which implement system calls (for unix, the specific OS,
or the specific OS/Architecture pair respectively) that need special handling
and list `//sys` comments giving prototypes for ones that can be generated.
The mksyscall.pl script takes the `//sys` and `//sysnb` comments and converts
them into syscalls. This requires the name of the prototype in the comment to
match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
prototype can be exported (capitalized) or not.
Adding a new syscall often just requires adding a new `//sys` function prototype
with the desired arguments and a capitalized name so it is exported. However, if
you want the interface to the syscall to be different, often one will make an
unexported `//sys` prototype, an then write a custom wrapper in
`syscall_${GOOS}.go`.
### types files
For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
`types_${GOOS}.go` on the old system). This file includes standard C headers and
creates Go type aliases to the corresponding C types. The file is then fed
through godef to get the Go compatible definitions. Finally, the generated code
is fed though mkpost.go to format the code correctly and remove any hidden or
private identifiers. This cleaned-up code is written to
`ztypes_${GOOS}_${GOARCH}.go`.
The hardest part about preparing this file is figuring out which headers to
include and which symbols need to be `#define`d to get the actual data
structures that pass through to the kernel system calls. Some C libraries
preset alternate versions for binary compatibility and translate them on the
way in and out of system calls, but there is almost always a `#define` that can
get the real ones.
See `types_darwin.go` and `linux/types.go` for examples.
To add a new type, add in the necessary include statement at the top of the
file (if it is not already there) and add in a type alias line. Note that if
your type is significantly different on different architectures, you may need
some `#if/#elif` macros in your include statements.
### mkerrors.sh
This script is used to generate the system's various constants. This doesn't
just include the error numbers and error strings, but also the signal numbers
an a wide variety of miscellaneous constants. The constants come from the list
of include files in the `includes_${uname}` variable. A regex then picks out
the desired `#define` statements, and generates the corresponding Go constants.
The error numbers and strings are generated from `#include <errno.h>`, and the
signal numbers and strings are generated from `#include <signal.h>`. All of
these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
`_errors.c`, which prints out all the constants.
To add a constant, add the header that includes it to the appropriate variable.
Then, edit the regex (if necessary) to match the desired constant. Avoid making
the regex too broad to avoid matching unintended constants.
## Generated files
### `zerror_${GOOS}_${GOARCH}.go`
A file containing all of the system's generated error numbers, error strings,
signal numbers, and constants. Generated by `mkerrors.sh` (see above).
### `zsyscall_${GOOS}_${GOARCH}.go`
A file containing all the generated syscalls for a specific GOOS and GOARCH.
Generated by `mksyscall.pl` (see above).
### `zsysnum_${GOOS}_${GOARCH}.go`
A list of numeric constants for all the syscall number of the specific GOOS
and GOARCH. Generated by mksysnum (see above).
### `ztypes_${GOOS}_${GOARCH}.go`
A file containing Go types for passing into (or returning from) syscalls.
Generated by godefs and the types file (see above).
