# 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

* [Fatih Arslan](https://github.com/fatih)
* Windows support via @mattn: [colorable](https://github.com/mattn/go-colorable)

/*
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...")

# INI
[![Build Status](https://img.shields.io/travis/go-ini/ini/master.svg?style=for-the-badge&logo=travis)](https://travis-ci.org/go-ini/ini) [![Sourcegraph](https://img.shields.io/badge/view%20on-Sourcegraph-brightgreen.svg?style=for-the-badge&logo=sourcegraph)](https://sourcegraph.com/github.com/go-ini/ini)
![](https://avatars0.githubusercontent.com/u/10216035?v=3&s=200)
Package ini provides INI file read and write functionality in Go.
## Features
- Load from multiple data sources(`[]byte`, file and `io.ReadCloser`) with overwrites.
- Read with recursion values.
- Read with parent-child sections.
- Read with auto-increment key names.
- Read with multiple-line values.
- Read with tons of helper methods.
- Read and convert values to Go types.
- Read and **WRITE** comments of sections and keys.
- Manipulate sections, keys and comments with ease.
- Keep sections and keys in order as you parse and save.
## Installation
The minimum requirement of Go is **1.6**.
```sh
$ go get gopkg.in/ini.v1
```
Please add `-u` flag to update in the future.

go-flags: a go library for parsing command line arguments
=========================================================
[![GoDoc](https://godoc.org/github.com/jessevdk/go-flags?status.png)](https://godoc.org/github.com/jessevdk/go-flags) [![Build Status](https://travis-ci.org/jessevdk/go-flags.svg?branch=master)](https://travis-ci.org/jessevdk/go-flags) [![Coverage Status](https://img.shields.io/coveralls/jessevdk/go-flags.svg)](https://coveralls.io/r/jessevdk/go-flags?branch=master)
This library provides similar functionality to the builtin flag library of
go, but provides much more functionality and nicer formatting. From the
documentation:
Package flags provides an extensive command line option parser.
The flags package is similar in functionality to the go builtin flag package
but provides more options and uses reflection to provide a convenient and
succinct way of specifying command line options.
Supported features:
* Options with short names (-v)
* Options with long names (--verbose)
* Options with and without arguments (bool v.s. other type)
* Options with optional arguments and default values
* Multiple option groups each containing a set of options
* Generate and print well-formatted help message
* Passing remaining command line arguments after -- (optional)
* Ignoring unknown command line options (optional)
* Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
* Supports multiple short options -aux
* Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
* Supports same option multiple times (can store in slice or last option counts)
* Supports maps
* Supports function callbacks
* Supports namespaces for (nested) option groups
The flags package uses structs, reflection and struct field tags
to allow users to specify command line options. This results in very simple
and concise specification of your application options. For example:
```go
type Options struct {
Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
}
```
This specifies one option with a short name -v and a long name --verbose.
When either -v or --verbose is found on the command line, a 'true' value
will be appended to the Verbose field. e.g. when specifying -vvv, the
resulting value of Verbose will be {[true, true, true]}.
Example:
--------
```go
var opts struct {
// Slice of bool will append 'true' each time the option
// is encountered (can be set multiple times, like -vvv)
Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
// Example of automatic marshalling to desired type (uint)
Offset uint `long:"offset" description:"Offset"`
// Example of a callback, called each time the option is found.
Call func(string) `short:"c" description:"Call phone number"`
// Example of a required flag
Name string `short:"n" long:"name" description:"A name" required:"true"`
// Example of a value name
File string `short:"f" long:"file" description:"A file" value-name:"FILE"`
// Example of a pointer
Ptr *int `short:"p" description:"A pointer to an integer"`
// Example of a slice of strings
StringSlice []string `short:"s" description:"A slice of strings"`
// Example of a slice of pointers
PtrSlice []*string `long:"ptrslice" description:"A slice of pointers to string"`
// Example of a map
IntMap map[string]int `long:"intmap" description:"A map from string to int"`
}
// Callback which will invoke callto:<argument> to call a number.
// Note that this works just on OS X (and probably only with
// Skype) but it shows the idea.
opts.Call = func(num string) {
cmd := exec.Command("open", "callto:"+num)
cmd.Start()
cmd.Process.Release()
}
// Make some fake arguments to parse.
args := []string{
"-vv",
"--offset=5",
"-n", "Me",
"-p", "3",
"-s", "hello",
"-s", "world",
"--ptrslice", "hello",
"--ptrslice", "world",
"--intmap", "a:1",
"--intmap", "b:5",
"arg1",
"arg2",
"arg3",
}
// Parse flags from `args'. Note that here we use flags.ParseArgs for
// the sake of making a working example. Normally, you would simply use
// flags.Parse(&opts) which uses os.Args
args, err := flags.ParseArgs(&opts, args)
if err != nil {
panic(err)
}
fmt.Printf("Verbosity: %v\n", opts.Verbose)
fmt.Printf("Offset: %d\n", opts.Offset)
fmt.Printf("Name: %s\n", opts.Name)
fmt.Printf("Ptr: %d\n", *opts.Ptr)
fmt.Printf("StringSlice: %v\n", opts.StringSlice)
fmt.Printf("PtrSlice: [%v %v]\n", *opts.PtrSlice[0], *opts.PtrSlice[1])
fmt.Printf("IntMap: [a:%v b:%v]\n", opts.IntMap["a"], opts.IntMap["b"])
fmt.Printf("Remaining args: %s\n", strings.Join(args, " "))
// Output: Verbosity: [true true]
// Offset: 5
// Name: Me
// Ptr: 3
// StringSlice: [hello world]
// PtrSlice: [hello world]
// IntMap: [a:1 b:5]
// Remaining args: arg1 arg2 arg3

Package flags provides an extensive command line option parser.
The flags package is similar in functionality to the go built-in flag package
but provides more options and uses reflection to provide a convenient and
succinct way of specifying command line options.
Supported features
The following features are supported in go-flags:
Options with short names (-v)
Options with long names (--verbose)
Options with and without arguments (bool v.s. other type)
Options with optional arguments and default values
Option default values from ENVIRONMENT_VARIABLES, including slice and map values
Multiple option groups each containing a set of options
Generate and print well-formatted help message
Passing remaining command line arguments after -- (optional)
Ignoring unknown command line options (optional)
Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
Supports multiple short options -aux
Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
Supports same option multiple times (can store in slice or last option counts)
Supports maps
Supports function callbacks
Supports namespaces for (nested) option groups
Additional features specific to Windows:
Options with short names (/v)
Options with long names (/verbose)
Windows-style options with arguments use a colon as the delimiter
Modify generated help message with Windows-style / options
Windows style options can be disabled at build time using the "forceposix"
build tag
Basic usage
The flags package uses structs, reflection and struct field tags
to allow users to specify command line options. This results in very simple
and concise specification of your application options. For example:
type Options struct {
Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
}
This specifies one option with a short name -v and a long name --verbose.
When either -v or --verbose is found on the command line, a 'true' value
will be appended to the Verbose field. e.g. when specifying -vvv, the
resulting value of Verbose will be {[true, true, true]}.
Slice options work exactly the same as primitive type options, except that
whenever the option is encountered, a value is appended to the slice.
Map options from string to primitive type are also supported. On the command
line, you specify the value for such an option as key:value. For example
type Options struct {
AuthorInfo string[string] `short:"a"`
}
Then, the AuthorInfo map can be filled with something like
-a name:Jesse -a "surname:van den Kieboom".
Finally, for full control over the conversion between command line argument
values and options, user defined types can choose to implement the Marshaler
and Unmarshaler interfaces.
Available field tags
The following is a list of tags for struct fields supported by go-flags:
short: the short name of the option (single character)
long: the long name of the option
required: if non empty, makes the option required to appear on the command
line. If a required option is not present, the parser will
return ErrRequired (optional)
description: the description of the option (optional)
long-description: the long description of the option. Currently only
displayed in generated man pages (optional)
no-flag: if non-empty, this field is ignored as an option (optional)
optional: if non-empty, makes the argument of the option optional. When an
argument is optional it can only be specified using
--option=argument (optional)
optional-value: the value of an optional option when the option occurs
without an argument. This tag can be specified multiple
times in the case of maps or slices (optional)
default: the default value of an option. This tag can be specified
multiple times in the case of slices or maps (optional)
default-mask: when specified, this value will be displayed in the help
instead of the actual default value. This is useful
mostly for hiding otherwise sensitive information from
showing up in the help. If default-mask takes the special
value "-", then no default value will be shown at all
(optional)
env: the default value of the option is overridden from the
specified environment variable, if one has been defined.
(optional)
env-delim: the 'env' default value from environment is split into
multiple values with the given delimiter string, use with
slices and maps (optional)
value-name: the name of the argument value (to be shown in the help)
(optional)
choice: limits the values for an option to a set of values.
This tag can be specified multiple times (optional)
hidden: if non-empty, the option is not visible in the help or man page.
base: a base (radix) used to convert strings to integer values, the
default base is 10 (i.e. decimal) (optional)
ini-name: the explicit ini option name (optional)
no-ini: if non-empty this field is ignored as an ini option
(optional)
group: when specified on a struct field, makes the struct
field a separate group with the given name (optional)
namespace: when specified on a group struct field, the namespace
gets prepended to every option's long name and
subgroup's namespace of this group, separated by
the parser's namespace delimiter (optional)
command: when specified on a struct field, makes the struct
field a (sub)command with the given name (optional)
subcommands-optional: when specified on a command struct field, makes
any subcommands of that command optional (optional)
alias: when specified on a command struct field, adds the
specified name as an alias for the command. Can be
be specified multiple times to add more than one
alias (optional)
positional-args: when specified on a field with a struct type,
uses the fields of that struct to parse remaining
positional command line arguments into (in order
of the fields). If a field has a slice type,
then all remaining arguments will be added to it.
Positional arguments are optional by default,
unless the "required" tag is specified together
with the "positional-args" tag. The "required" tag
can also be set on the individual rest argument
fields, to require only the first N positional
arguments. If the "required" tag is set on the
rest arguments slice, then its value determines
the minimum amount of rest arguments that needs to
be provided (e.g. `required:"2"`) (optional)
positional-arg-name: used on a field in a positional argument struct; name
of the positional argument placeholder to be shown in
the help (optional)
Either the `short:` tag or the `long:` must be specified to make the field eligible as an
option.
Option groups
Option groups are a simple way to semantically separate your options. All
options in a particular group are shown together in the help under the name
of the group. Namespaces can be used to specify option long names more
precisely and emphasize the options affiliation to their group.
There are currently three ways to specify option groups.
1. Use NewNamedParser specifying the various option groups.
2. Use AddGroup to add a group to an existing parser.
3. Add a struct field to the top-level options annotated with the
group:"group-name" tag.
Commands
The flags package also has basic support for commands. Commands are often
used in monolithic applications that support various commands or actions.
Take git for example, all of the add, commit, checkout, etc. are called
commands. Using commands you can easily separate multiple functions of your
application.
There are currently two ways to specify a command.
1. Use AddCommand on an existing parser.
2. Add a struct field to your options struct annotated with the
command:"command-name" tag.
The most common, idiomatic way to implement commands is to define a global
parser instance and implement each command in a separate file. These
command files should define a go init function which calls AddCommand on
the global parser.
When parsing ends and there is an active command and that command implements
the Commander interface, then its Execute method will be run with the
remaining command line arguments.
Command structs can have options which become valid to parse after the
command has been specified on the command line, in addition to the options
of all the parent commands. I.e. considering a -v flag on the parser and an
add command, the following are equivalent:
./app -v add
./app add -v
However, if the -v flag is defined on the add command, then the first of
the two examples above would fail since the -v flag is not defined before
the add command.
Completion
go-flags has builtin support to provide bash completion of flags, commands
and argument values. To use completion, the binary which uses go-flags
can be invoked in a special environment to list completion of the current
command line argument. It should be noted that this `executes` your application,
and it is up to the user to make sure there are no negative side effects (for
example from init functions).
Setting the environment variable `GO_FLAGS_COMPLETION=1` enables completion
by replacing the argument parsing routine with the completion routine which
outputs completions for the passed arguments. The basic invocation to
complete a set of arguments is therefore:
GO_FLAGS_COMPLETION=1 ./completion-example arg1 arg2 arg3
where `completion-example` is the binary, `arg1` and `arg2` are
the current arguments, and `arg3` (the last argument) is the argument
to be completed. If the GO_FLAGS_COMPLETION is set to "verbose", then
descriptions of possible completion items will also be shown, if there
are more than 1 completion items.
To use this with bash completion, a simple file can be written which
calls the binary which supports go-flags completion:
_completion_example() {
# All arguments except the first one
args=("${COMP_WORDS[@]:1:$COMP_CWORD}")
# Only split on newlines
local IFS=$'\n'
# Call completion (note that the first element of COMP_WORDS is
# the executable itself)
COMPREPLY=($(GO_FLAGS_COMPLETION=1 ${COMP_WORDS[0]} "${args[@]}"))
return 0
}
complete -F _completion_example completion-example
Completion requires the parser option PassDoubleDash and is therefore enforced if the environment variable GO_FLAGS_COMPLETION is set.
Customized completion for argument values is supported by implementing
the flags.Completer interface for the argument value type. An example
of a type which does so is the flags.Filename type, an alias of string
allowing simple filename completion. A slice or array argument value
whose element type implements flags.Completer will also be completed.

# 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
```
